## CISA exposes malware kits deployed in Ivanti EPMM attacks
## Ionut Ilascu
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has published an analysis of the malware deployed in attacks exploiting vulnerabilities affecting Ivanti Endpoint Manager Mobile (EPMM).
The flaws are an authentication bypass in EPMM’s API component (CVE-2025-4427) and a code injection vulnerability (CVE-2025-4428) that allows execution of arbitrary code.
The two vulnerabilities affect the following Ivanti EPMM development branches and their earlier releases: 11.12.0.4, 12.3.0.1, 12.4.0.1, and 12.5.0.0.
Ivanti addressed the issues on May 13, but threat actors had already been exploiting them as zero days in attacks against “a very limited number of customers.”

Twenty years ago this week, I released the first public version of Nessus. Little did I know at the time the profound impact it would have both on the industry and on me personally.
Over this period of time, Nessus quite literally redefined the vulnerability management industry and profoundly influenced the security industry as a whole. Nessus is one of the most widely used security tools on the market today. I’m very proud to say that Nessus has helped 1.6 million enthusiasts become cybersecurity professionals – and I can’t even begin to tell you the number of people who have told me that Nessus launched their careers, and hearing that is always so personally gratifying.

Cryptography is like finding and patching system vulnerabilities. Both are a race. In the former, the race is between mathematicians finding efficient, hard-to-reverse computations and opposing mathematicians solving hard numerical problems to defeat them. In the latter, the race is between IT and malicious actors who may find the vulnerabilities first to exploit them. The race in encryption is fueled by the exponential increase in computing power outlined by Moore’s law, constantly driving the algorithms we use toward obsolescence.
For a long time, the golden standard in strong cryptography was based on schemes using the result of multiplying two prime numbe

This post was updated on Jan. 12, 2018 to include additional technical details and supplemental links.
The recently disclosed Meltdown and Spectre vulnerabilities started off 2018 with a somber note, as the attacks affect everything from desktops, laptops and mobile devices to cloud providers’ infrastructure. The flaws are present in nearly all modern microprocessors and can allow an attacker to access privileged memory by abusing a feature called speculative execution.
### Speculative execution
Speculative execution is a technique that allows a microprocessor to increase performance by operating on multiple branches of instructions at once

# Detecting macOS High Sierra root account without authentication
Nick Miles

Yesterday, Tenable™ released two plugins to detect macOS High Sierra installs which allow a local user to login as root without a password after several login attempts. Both plugins require authentication, however, there was one scenario where a user could log in over VNC protocol with the root account and no password if screen sharing was enabled. Today, we are releasing a plugin to remotely detect the vulnerability without authentication.
### Confirming the Vulnerability
One of my colleagues initially reported that exploitation was possible remotely over VNC after trying against his personal laptop. To confirm the report, I fired up tightVNC (an open source VP

Editor's note (Nov. 20, 2025): The material in this blog no longer reflects current capabilities. Tenable documentation offers the latest guidance here: https://docs.tenable.com/nessus/Content/configure-least-privilege-ssh-scan.htm
Credentialed scans have long been advocated as the quickest and most accurate way to perform a vulnerability assessment against any network. But like with all things technology, it runs into two usual roadblocks: people and processes.
When the topic of credentialed network scans is discussed it inevitably leads to questions such as, who is requesting access and why? What level of privileges is needed and why? Which commands will be run

As a companion to another post on hardening network devices and creating baseline configurations, I wanted to look at another area where standardizing configurations can pay off in a big way. While there is plenty of fertile ground out there, I decided to focus on some specific aspects of databases. As I started reviewing recent research, I noticed a couple of interesting things from the world of finance that likely aren’t radically different from most environments. Findings in both the Verizon 2017 Data Breach Investigations Report (DBIR) and the SecurityScorecard 2016 Financial Industry Cybersecurity Research Report bear out that there are a number of challenges for security pros across financi

Printers. They are everywhere. In big businesses. In small businesses. In our homes. In our schools. Wherever you go, there they are. But where are they in your threat model? When was the last time you updated the firmware? Do you know if there are public exploits for your printer?
For example, in early April, Hewlett Packard released a security bulletin titled, HP PageWide Printers, HP OfficeJet Pro Printers, Arbitrary Code Execution. The bulletin states:
> A potential security vulnerability has been identified with certain HP printers. This vulnerability could potentially be exploited to execute arbitrary code.

# Rediscovering the Intel AMT Vulnerability

On May 1, 2017 Intel disclosed the AMT vulnerability (INTEL-SA-00075), but details of that vulnerability were not made public. However, Tenable researchers were able to overcome this challenge and make Tenable the first to deliver Intel AMT vulnerability detection capabilities to customers, just minutes after Intel’s announcement yesterday. This is the story of how we did it.
### The hunt
The first thing our research team tried was to set up a known vulnerable target. After some searching, we found a Dell computer that had Intel AMT support but there was a problem. It was not configured/provisioned for what we needed.
The Intel Management Engine Interface (MEI) driver was installed but

Kali Linux, a Linux distribution designed specifically for penetration testing, comes prepackaged with many pen test tools. Nessus® provides a penetration tester with a wealth of capabilities that will assist in the engagement, such as:
- Identifying local and remote vulnerabilities
- Configuration and compliance audits
- Checking for default credentials
- Web application scanning
Nessus isn’t installed on Kali Linux by default, but this post will show you how to install Nessus and provide some suggestions for using it in a penetration testing engagement to gain a more complete understanding of your organization's security posture.

What scans do you use? Tenable customers can assess their security risks from information gathered by vulnerability and compliance scans. In this blog, I’ll show you how to build a customized scan that helps diagnose authentication issues that show up when running those scans. I call it the Quick Credential Debug Scan, or QCD for short.
QCD is popular because of its speed and its light impact on the target. QCD performs key tests required to access the target system. Even though the scan requires credentials, the scan does not probe for vulnerability or compliance information.
The Host Access Capabilities component in the Credentialed Windows Scanning dashboard shows some of the diagnostic results te

# Do You Know Where Your UPnP Is?
Jacob Baines
October 20, 2016

Much has been said about the security of Universal Plugin and Play (UPnP) over the years. There have been FBI warnings, security researchers have published papers, and even Forbes has told us to disable UPnP. But how do you know if UPnP servers are on your network? Are there specific services we should worry about? Do we really need to be concerned about UPnP?
### Finding UPnP services
To answer some of these questions, Tenable wrote a simple Python script called upnp_info.py. You can find it on our GitHub. The script finds all UPnP services and enumerates their functionality. Check out the README for full details.
Some of you may be thinking, “I don’t need that script. I know I disabled UPn

# Expanding on a Known Vulnerability: Attacking with Jython
Jacob Baines
September 7, 2016

As a Reverse Engineer at Tenable, I investigate disclosed vulnerabilities in order to write remote plugins for the Nessus® vulnerability scanner. Each investigation is unique and presents its own set of challenges. In some cases, new vulnerabilities are uncovered. One such investigation happened earlier this year when I was analyzing CVE-2016-3737 in Red Hat JBoss Operations Network (JON).
When I began looking into CVE-2016-3737, the entry in the National Vulnerability Database was empty but there was a Red Hat security advisory that read:
> It was discovered that sending specially crafted HTTP request to the JON server would allow deserialization of that message w

# Post-Hunt Survival Skills: Scope and Triage

Inevitably when you threat hunt - you will find something. What happens next? A barrage of questions ensues:
- Is it an incident, administrative activity, an external attacker in your environment?
- How did the attackers get in, what did they touch, and what systems and services are impacted.
- Is it simply a misconfiguration of a service, uncovered by the hunt?
Answering these questions can be the most unexpectedly challenging aspect of threat hunting, depending on the size and maturity of your organization. How do you determine when to escalate and call in responders?
Tenable provides many features to find and scope the breadth of an incident prior to the fire drill

# Auditing Docker with Nessus 6.6

“It worked in Dev, it works in Dev. Don’t know why it’s not working in production. It’s an Ops problem now.”
Many of us have lived through a failed production deployment of an application at least once. And unfortunately for some, the memories from such failed deployments can haunt for the rest of our lives. But thanks to a relatively old technology (but gaining traction recently), such things could quickly become a thing of the past. Welcome containerization—or as most people know it—Docker containers.
### Why Docker?
Developers have long sought a system with which they could build a piece of software once, package it, and then run it anywhere—without having to worry about dependencies, lib

# Ghost in the Machine: “MouseJack” Wireless Mouse and Keyboard Injection Vulnerability (Updated)

It was over 6 years ago that the wireless keyboard sniffer project known as “Keykeriki” was first demonstrated. The sniffer allowed someone to eavesdrop on what is being typed as each key was pressed on the keyboard. Recently, another vulnerability dubbed “MouseJack” has been discovered in the way some wireless devices, such as the Logitech Unifying Receivers for wireless keyboards process received RF packets, allowing keystroke injection that bypasses encryption. Exploiting this vulnerability involves transmitting RF packets to a vulnerable vendor dongle and requires physical proximity to the target computer. This vulnerability

Most of us involved with vulnerability management have probably used a Nessus® filter to display specific reporting results. For example, I have used a query to select all of the Windows servers in an environment, and then report on the high and critical severity vulnerabilities. Queries like this focus analysis and increase insight from reports. Report queries are useful for vulnerability management – so valuable that their usage raises two questions in my mind.
First, can we apply queries across the entire vulne

Almost every day we face the constant challenge of choosing from things that need our urgent attention and ones that are important. How we classify and prioritize these items largely reflects our true character. Procrastinate enough, and it doesn't take long for important items to become urgent. Fail to distinguish urgent items from the important, and it could lead to catastrophic failure. In short, identifying our priorities and executing them in our daily workflow is the key to success in any walk of life. And when it comes to vulnerability management, it’s no different.

Note: This 2015 blog includes some outdated information. For the latest information on how to leverage active scanning and offline assessments for pen testing, please read our newer blog on How to Maximize Your Penetration Tests with Nessus.
While similar, a penetration test and a vulnerability assessment are not the same thing. Used together however, especially if you are doing both active and passive vulnerability scanning, they can be extremely complementary.
Vulnerability assessments and penetration tests are similar because they both look for holes or vulnerabilities

There was a time in early 2000 when the word "virtualization" was synonymous with VMware, and rightly so. After all, VMware started the second coming of this revolutionary technology after IBM. But open source hypervisor solutions such as Xen and KVM have been slowly nibbling at this market share and have made names for themselves in the past decade. Today, it is not uncommon to see multi-hypervisor deployments in a typical data center.
Over time, virtualization technology has matured, and the hypervisors that form the basis of this technology have become feature rich. For basic tasks such as managing virtual machine life cycles or live migration, most major

The latest Patch Tuesday from Microsoft (November 11, 2014) includes fixes for some major vulnerabilities, including remote code execution bugs affecting core Windows components and Internet Explorer. The three major bulletins of note are MS14-064, MS14-065 and MS14-066, all of which have a CVSS score of above 9.0.
MS14-064 patches a bug in the Windows Object Linking and Embedding (OLE) library which appears to be a continuation of vulnerabilities disclosed last month in MS14-060 (aka Sandworm). Researchers have already seen this vulnerability used in the wild for exploitation through the use of malicious PowerPoint files. On the other hand, MS14-065 is a cumulative update that fixes 17

Several new vulnerabilities were disclosed in OpenSSL yesterday (yes the very same one which led to the Heartbleed vulnerability), along with updates for the popular open-source SSL library. One of the vulnerabilities is fairly serious, as it could allow for Man-In-The-Middle attacks under certain circumstances. Interesting notes about this new vulnerability include:

# Cyber-Criminals Don’t Take the Holidays Off

It’s nearly upon us. Black Friday weekend… the beginning of the holiday shopping and party season that will generate an estimated $5.4 billion windfall for cyber-criminals!
This holiday season we decided it would be fun to create an infographic that illustrated the relationship between holiday spending, payment card transactions, online, offline and mobile commerce, cyber-crime and remotely exploitable vulnerabilities.
Over the next month you’re likely to hear Andy Williams singing, “It’s the most wonderful time of the year.” This may be especially true for retailers in many parts of the world, who take in 20-50% of their annual revenues between now and New Year’s Eve.

A new compliance plugin is now available for Nessus customers to audit the configuration settings of Citrix XenServer. XenServer is an open-source virtualization platform used to manage cloud, server, and desktop virtual infrastructures. This new Nessus functionality allows customers to harden the virtualization layer of their infrastructure, an important component in an organization's security as so many systems are able to run on the virtual platform.
Given the similarities between XenServer and UNIX operating systems, the new XenServer compliance plugin is an extension of the UNIX compliance checks.

# Keeping Anti-Virus in Check

Nessus will generate a finding if the scan target has an Anti-Virus agent deployed with the virus detection rules out of date. We've often received feature requests asking us to allow customers to set a grace period (in days) to avoid generating this alert. Such a preference was added this week under the heading 'Antivirus Software Check':
Why does a customer need this? Often customers have their own process for distributing Anti-Virus signature updates rather than using distribution automation that comes directly from their AV vendor. This process exists to allow IT to QA the impact of the rules on their applications and desktop environments before they are pushed out. There have been several instan

The Nessus vulnerability scanner now performs configuration and compliance audits for NetApp storage devices.
### Securing All Three Layers
Nessus recently added capabilities to perform configuration and compliance audits in two major areas of the enterprise. First, Tenable added the ability to audit enterprise Cisco networking equipment, namely Cisco's Nexus NX-OS. Then, we expanded and greatly enhanced support for auditing VMware vSphere and vCenter. Now, we've added support for auditing NetApp Data ONTAP storage devices. The new .audit is primarily based off the NetApp hardening guides (technical reports TR-3649 and TR-3996).

The vulnerability modification settings provide Nessus users with the ability to change the severity of findings, or hide them completely for a single host, a single scan, all future scans, or a specific time period. Nessus users may wish to modify vulnerability finding for a variety of reasons, including:

Every network is different, and tuning your Nessus scan policy can yield great results. A new plugin has been added for Nessus 5.2 and higher (plugin ID #66359) which will analyze the scan results for your environment and the scan settings that were used, and then suggest improvements for a better audit.
For example, I scanned a Windows system on the network without entering credentials. When the Nessus scan was complete, I was presented with a "tip" that, if implemented, would yield more complete vulnerability scanning results:
Tips appear automatically once your scan completes. The initial set of tips will include several different recommendations. For example, if the targets presen

Ensuring that patches are applied to systems is a complex problem. Pinpointing those patches that must be applied to become current requires careful analysis. The new Nessus consolidated “Patch Report” plugin identifies which patches to apply to protect your systems.
### The Challenges of Patching
Regardless of platform, there are a plethora of patches to be applied. I tend to break them up into three general categories:

# Scanning and Patch Auditing VMware Using Nessus

### The Revolution Will Be Virtualized
I've worked in IT since my first computer programming job while still in college. I've visited several data centers and server rooms over the years, and I agree with the statement, "If you've seen one data center, you've seen them all." However, I've noticed a significant shift in the last several years – more and more data centers are virtual. This translates to smaller server rooms, less racks, and less servers generating heat and making freight train-like sounds with their cooling fans. Even in my own home computer lab, I use virtualization. In fact, my laptop is a traveling data center, housing at least half a dozen or more virtual mach

# Using Nessus to Discover Malware and Botnet Hosts
Paul Asadoorian
April 18, 2013
4 Min Read
When performing a vulnerability scan (or even a penetration test), you must be able to spot a host that is already compromised, contains malware, or is part of a botnet. When malware exists on a host you're testing, the right course of action is to switch from scanning or penetration testing mode into forensics mode to determine how the system was compromised and implement a plan to remove the backdoors that may exist. Unfortunately the best way to be certain all malware has been removed is to format the hard drive and re-install the operating system and all software (provided malware has not hidden inside the BIOS, UEFI, or other hardware sub-system).

### Comprehensive Linux and UNIX Patch Knowledge
Ensuring that your Linux and UNIX systems are up-to-date with the latest patches is no small task. Largely due to ever evolving Linux distributions and virtual machine (VM) sprawl, you likely have a much larger Linux footprint than ever before. Systems administrators must keep tabs on the plethora of patches being released for each platform. Unlike Microsoft Windows systems, which have a regular patch cycle, Linux and UNIX variants, for the most part, release patches for software as they become available.
Thankfully, Nessus is here to help. More than 1,000 plugins have been released this year that check for local Linux and UNIX operatin

Nessus contained the ability to perform compliance audits against VMware ESX for some time. However, the methods used SSH credentials to log into the VMware platform and perform the audit checks. SSH has been disabled by default on newer versions of ESX/ESXi.
Tenable has now implemented new checks using the VMware SOAP API (which is already being used by existing plugins to pull information about VMware systems). Tenable has developed APIs for both ESXi (the interface available free of charge to manage virtual machines (VMs) on ESX/ESXi) and vCenter (an add-on product available from VMware at some cost to manage one or more ESX/ESXi servers). Supported versions are ESXi

April 4, 2013

This year marks the 15th anniversary of the Nessus® vulnerability scanner. Over the years, there have been many significant improvements to Nessus, and it’s repeatedly proven to be an essential part of my information security toolset.
I started using Nessus about 13 years ago. As a UNIX systems administrator, I was tasked with implementing security across our systems in preparation for a security audit. Naturally, one of the pieces of software I discovered was Nessus, which allowed me to scan my systems, reduce the number of exposed services, and apply patches to the operating system and software.
Fast forward to today, and guess what? It’s still a crucial part of my security toolkit — I use Nessus in suppo

### Introduction
In recent years, Palo Alto firewalls have gained popularity within enterprise networks. Tenable Nessus ProfessionalFeed® customers can now audit the configuration of PAN-OS™-based Palo Alto Networks firewalls. Nessus can audit the firewall operational configurations and allow Palo Alto firewall reports to be embedded into Nessus reports.
Nessus communicates with the Palo Alto XML API to access the configuration and report data. The web interface must be enabled (either HTTP or HTTPS) on the firewall. Nessus requires credentials to the devices being audited; Superuser or Superuser (readonly) accounts for PAN-OS less than or equal to version 4.1.0

### Hardening Microsoft Office
Microsoft® Office® is ubiquitous in today’s work environment. MS Office applications offer many security configuration options that can reduce the likelihood of exploitation. However, the default configuration settings typically don’t provide a strong security posture. The requirements and recommendations documented in common regulations and security guides are a great start to securing your Office installations. Tenable customers can also measure and evaluate the security of their Microsoft Office Suite environment using Nessus® and Tenable SecurityCenter™ audit compliance policy files.

### Integrating with Patch Management
In December 2011, Tenable announced that Nessus could integrate with many popular patch management solutions. Initial support was offered for Red Hat Network Satellite server, Microsoft WSUS / SCCM, and VMware Go. More recently, support was added for IBM Tivoli Endpoint Manager (TEM) for Patch Management. Integration with patch management solutions means Nessus and SecurityCenter can collect information about patches from systems without requiring credentials to the targeted hosts themselves.
Today, two new plugins extend our previous integration to automatically cross-reference vulnerabilities from credentialed patc

Nessus has plugins that can pull out current (or previously used) wireless service set identifiers (WiFi SSIDs) that Windows and OS X systems have connected to in the past. The following plugins are used:
- Mac OS X Wireless Networks List (63340) - This new plugin reports a history of wireless networks used by the target system.
- Windows Wireless SSID (WMI) (25197) - Using WMI, this plugin reports the existing wireless network the target host is currently using.
For both of the above checks, you must enter valid system credentials for the target hosts. Below is a sample report from an OS X system:

### Samsung Printers Contain an SNMP Backdoor
Samsung is not the most well-known printer manufacturer in the world (although they hold 28.5% of the consumer TV market). However, they manufacture a full line of printers and multi-function devices for both home and business use. Samsung also manufactures "some" printers for Dell, though an official list is currently unknown.
On November 28, 2012, US-CERT issued an advisory warning that select Samsung/Dell printers contained a hardcoded backdoor that could be accessed via SNMP. There are a lot of interesting facts surrounding this vulnerability, including:

### Keeping Your Firewalls in Check
Ensuring that your network infrastructure, in particular your routers and firewalls, is secure and maintains its integrity is critical to successfully defending your network. If an attacker were to gain control of these types of systems, they could potentially impact the security of your network as a whole. For example, an attacker with access to your firewall could read the firewall rules and use the information to selectively attack open services and create backdoors that would slip through your firewall.

Protecting your vulnerability data from unauthorized users, whether the threat comes from external attackers or malicious insiders, is an important part of a vulnerability management program. Nessus allows users to configure SSL to provide both privacy and authentication. SSL can be configured locally or integrated into your own PKI infrastructure, allowing Nessus to be compliant with in-house security policies and standards.
While Nessus comes with a default set of SSL certificates, some configuration by the end user is required to eliminate web browser errors indicating invalid certificates. First, the hostname or IP address tied t

# Nessus Scanning Windows 8 Hosts

The new Windows 8 interface provides a very different user experience than past Microsoft operating systems. Nessus can enumerate and detect vulnerabilities on Windows 8 hosts.
Recently, Microsoft made several announcements surrounding new technology, including a new operating system (Windows 8) and a new tablet platform called "Surface." Windows 8 will present a new interface and several new changes under the hood. They're an offshoot of the new platform called Windows RT, a small, fast, and lightweight version designed to run on ARM-based tablets. In fact, this is much of the reason behind the concept of Windows 8 -- it’s meant to run on tablets and touch screens. Windows Phone 8 is the n

Nessus and SecurityCenter now support Tivoli Endpoint Manager (TEM) as a patch management platform in which patch-level information can be extracted for given scan targets.
### Nessus Patch Management Support
We are pleased to announce new support for IBM Tivoli Endpoint Manager (TEM) for Patch Management (formerly known as BigFix). This new capability allows us to use the information gathered by TEM from systems where we may not have credentials or we’re unable to reach such systems over the network. The TEM integration is configured similarly to our integration with other patch management solutions where credentials and the server IP address/h

Until now, the Nessus interface has been using Flash, which has a number of advantages as a development platform, but also has a lot of drawbacks. One of the reasons we implemented a Flash interface for Nessus was that Flash "behaves the same on every browser" (which turns out is not always the case), and it was reasonably fast to run the client (it's now outperformed by the newest javascript engines). Flash also doesn't offer a good "mobile" user experience, if at all. So, it makes sense to use a standard-based technology, and we're moving to HTML5.
So we've released the HTML5 interface as a public beta -- the default Nessus interface will still be Flash for now, but if you connect

# Auditing Open Ports on Windows Systems Using Nessus
Paul Asadoorian
September 26, 2012

Tenable recently released three new checks used for auditing the configurations of Windows systems. The new configuration auditing options allow users to audit open ports. This post provides details about the three new checks, and describes how Nessus users could use them to maintain tight control over the number of open ports on their Windows systems.
### 1. AUDIT_ALLOWED_OPEN_PORTS
This check allows users to audit the list of open ports against an "allowed" list of ports that can be open on a target. For example, let’s assume there is a company policy to only allow SMB ports 445 and 139 to be open on a target. The resulting configuration audit would look as follows:

### Passwords are Like Underwear, and It's Laundry Day
Perhaps one of the most easily overlooked security problems in the industry is password security. I'm not referring to the stored end-user password problems (discussed here), but the default (or weak) usernames and password combinations used to protect common administrative interfaces to applications and systems.
The problem stares us in the face every day, each time we log into a router, database management system, or remote access console and enter a password. Often we put a lot of time and effort into securing the end user-facing passwords, such as implementing account lockout password policies and forcing

Nessus has provided organizations with a wide variety of techniques for identifying vulnerabilities in your IT infrastructure. The foundation has long been proven, as Nessus will accurately identify vulnerabilities across the network, using credentials to gather patch level and other information, and assist with system hardening by performing compliance checks.
However, in recent years there have been significant improvements made to both the Nessus scanning engine and its feature set. Of course, over time Nessus has been able to consistently shave the time it takes to remotely scan systems and networks. In addition, Nessus has added support for thre

Many guidelines and compliance standards state that in order to be "secure" or "compliant" all of your systems must be patched. Turns out that this is easier said than done. Just when you believe your systems to be patched, something fails and patches seemingly disappear. We can then apply the "falling off" principal to several other areas of information technology, such as web applications, configuration management, and anti-virus software. How do security controls in these areas fall off? Below are some reasons how this might happen and what you can do to help correct the problems.

### Malicious Process Detection Updates
A short time ago, Tenable released a new plugin to perform Malicious Process Detection (plugin ID 59275). Originally, it identified all possible malicious processes and reported the risk level as "High." This has now been split into two plugins; the original plugin that detects processes as malware which now uses the risk level of "critical," and a new plugin titled Malicious Process Detection: Potentially Unwanted Software (plugin ID 59641):

### The Trouble with Remote Access
Remote access protocols are certainly one of the long-standing topics discussed when it comes to information security. Most security practitioners have had to deal with the threats and risks posed by the wide range of protocols used to remotely manage and access systems, including Telnet, SSH, RDP and even third-party providers such as GoToMyPC. Convenience is heavily weighed against security, as users and administrators require access to the systems, yet security in the forms of authentication and encryption seemingly "get in the way." This debate has come up in my career more times than I care to remember. When I first se

### Keeping Malware in Check
A limitation of anti-virus (AV) agents is they often do not evaluate the entire known malware sample found running on a system. Polymorphic and mutating viruses make it possible for one AV vendor to detect a malicious sample and another to completely miss it. It's not feasible to run every AV program available on the market today in your network to make up for gaps in coverage. Nessus alre

### Encryption is Only as Strong as the Key
In this case, encryption breaks down because the OS X user's password (used to unlock an encrypted volume) is logged in clear-text via debugging function to a system-wide readable log file. In this scenario, a user running Mac OS X 10.7.3 would encrypt their drive using File Vault, which is included with OS X and encrypts the entire contents of your hard drive. When your system boots up, or you access your files over AFP (Apple's File Sharing Protocol), the system uses your password to decrypt the contents of the drive and your home folder. Debugging in vulnerable versions was enabled such that the password was logged i

### Embedded Device Security Woes
Having researched embedded device security for quite some time, it never ceases to amaze me how manufacturers present vulnerabilities in their products. While I do not want to start picking on specific manufacturers (as the development process is not as easy as one might think), RuggedCom's Rugged Operating System (ROS) recently had a vulnerability disclosed. According to their website: "RuggedCom [a Siemens business unit] designs and manufactures rugged communications equipment for harsh environments." They produce a full product suite, from Ethernet switches to wireless networking, aimed at industrial (SCADA) usage.

### Covering All Your Bases
Internet-facing servers are a popular attack target: They are accessible to everyone on the Internet and can easily be probed for vulnerabilities. Based on exposure alone, Internet-facing servers present a higher risk of becoming compromised. This risk needs to be mitigated if organizations must provide access to services such as web, mail, and VPN connectivity. It is therefore important that these servers are regularly assessed for potential vulnerabilities (and more important that s

## Ron Gula on Why Tenable Fits the Department of Defense
Earlier this week, Tenable formally announced the company's products had been selected as the basis for the Assured Compliance Assessment Solution (ACAS), the Defense Information Systems Agency's Department of Defense-wide program for managing vulnerability and configuration assessments. Tenable co-founder and CEO Ron Gula took a moment to chat about the selection, and what it means to the entire Tenable team. You can watch here:

# Compliance Auditing with Microsoft PowerShell
Paul Asadoorian

### Compliance Auditing with PowerShell
Microsoft's PowerShell framework has been part of their product line for quite some time. In recent years, it has played a major role in new operating system versions (such as Window 7 and Windows Server 2008) thanks to its inclusion in common engineering criteria. All future Microsoft server products will have PowerShell support integrated in them by default. This means Microsoft products will benefit from a single management interface, rather than a mixed usage of the registry, WMI, or other system files/utilities.
For those unfamiliar with PowerShell, it's a command-line shell meant to perform administrative tasks using cmdlets. Cmdlet

# Nessus 5.0.1 Released
Paul Asadoorian
April 16, 2012

Tenable is pleased to announce the release of Nessus 5.0.1! This is a point release (moving from 5.0 to 5.0.1), containing enhancements and minor bug fixes. This release improves the stability on all platforms, and solves Windows-specific issues related to installation and packet forgery.
## New features
From a user perspective, the only change is that it is now possible to specify a separate list of UDP and TCP ports to scan on all targets. This is set in the "Port scanner range" field when you create a new policy or modify an existing one (e.g. if you wanted to scan TCP ports 1-1024 and UDP ports 1-200 the syntax is: "T:1-1024,U:1-200"). Also, a build for FreeBSD version 9 is now available.

# Using Nessus 5 to Raise the Value of Penetration Testing
Ron Gula
February 23, 2012
6 Min Read
Cross referencing the results of your vulnerability scans with the list of public exploits helps identify likely targets for authorized penetration testing teams. Removing these vulnerabilities significantly raises the value of a penetration test since the team will have to work much harder to find issues that aren’t found through automation. There are many subtle issues to consider when correlating available exploits with vulnerabilities. In this blog entry, we’ll highlight these issues by considering exploit correlation with attacks available from the Metasploit project, Core, and Immunity with the results of a very large Nessus scan of several thousand web servers.

With Nessus 5, the results from a single vulnerability scan can be filtered to show which hosts have ancient vulnerabilities, which hosts aren’t being managed, and also which hosts have been exploitable for long periods of time. This blog entry discusses the new Nessus 5 filters, how they can be used to track high-risk vulnerabilities, and how enterprise users of Tenable SecurityCenter can leverage these filters for dashboards and asset-based reporting.

Penetration tests are typically a point-in-time exercise to determine if a remote adversary or malicious insider can compromise systems that contain sensitive data. Most organizations do not conduct penetration tests on a daily basis. Instead they schedule them annually, quarterly, or in some cases monthly. Penetration tests procured on a consulting engagement are often limited to key systems and assets rather than the entire network of systems. This diminishes the value of the penetration test as the results quickly become outdated and may not be relevant to new systems or recent network changes. However, by correlating the availability of exploits with a continuous monitoring progra

# Patch Management Integration with Nessus Released
Paul Asadoorian
December 6, 2011
2 Min Read
Today, Tenable Network Security announced integration between Nessus and a variety of patch management systems that will simplify scanning in cases where credentialed scans are difficult or impossible. The integration allows Nessus and SecurityCenter users to establish direct links to patch management systems. This simplifies patch audits as the systems in your environment do not all have to contain credentials in order to be scanned. You simply need to give Nessus credentials to your patch management server. This integration enhances compliance programs and helps eliminate confusion about the patch status of systems between IT operations and network security teams.

### Why is "Cloud Storage" So Appealing?
Services such as DropBox use the cloud to enable users to share files with others and transfer work from office to home and back. The challenge is two-fold:
1. Determine how this and other cloud-based technologies align with the organization’s security policies and compliance mandates.
2. Monitor use of these solutions to ensure compliance and limit exposure while preserving benefit.
Users often turn from sanctioned file sharing methods when they reach the limits of email and internal file sharing capacity, performance, and functionality. Email was not intended to share large files, and very often restrictions are implemented on the size of an

In a perfect world, there would be no vulnerabilities. In a perfect patching world there would be a patch for every vulnerability and we would always be able to patch all of our systems as soon as a patch was available. In the real world we do the best we can and struggle with testing cycles, incompatibilities, and legacy applications which means sometimes we have to leave insecure and unpatched systems in production.
There are a variety of situations that can cause exposure:
- Some patches break needed applications or cause compatibility problems
- Patches may not yet be available for a vulnerability but the systems must stay online and exposed Legacy applications or operating systems may still be required

### "The Untouchables"
An untouchable system is one on which you cannot install software (such as agents) or apply security fixes regularly. I have come up with several different examples of such systems, and tried to use examples here from my own experiences to define why they may fall into the "untouchable" category:
- Select SCADA systems - This is a broad category, but it boils down to computers that are used in control systems networks. While many may be considered to be "air-gapped" (physically disconnected from any other types of systems), that may not actually be the case since connectivity is required to manage the devices (especially those deployed in the field).

Next up on our Nessus top ten list is #8, which covers how to use Nessus to find web application vulnerabilities. I've broken out the process into four different methods supported by Nessus:
### 1. Test For Known Vulnerabilities
Nessus contains over 2,600 plugins that can fingerprint and detect known vulnerabilities in web applications. Any plugin listed in the "CGI Abuses" or "CGI Abuses: XSS" plugin families is written to enumerate vulnerabilities that have been publicly reported in a web application product, whether open source or commercial. To enable these plugins you must enable CGI scanning in a Nessus policy's "Preferences"

During the past few weeks, the Tenable R&D team has created several plugins to enhance SSL certificate auditing capability. Nessus will identify SSL certificates regardless of port and launch dozens of plugins to check for a variety of weaknesses and vulnerabilities. Three new plugins expand that auditing capability to more effectively audit your organization.

Being the Product Evangelist for Tenable Network Security gives me some interesting insight into how the community views the features of our products. I meet some people who provide us with awesome suggestions for improvements and I also meet some people who scan their networks at semi-regular intervals using the default set of policies, unaware of the huge variety of features that Nessus includes.
Hence the project I have been working on: with help and support from the community and my fellow co-workers at Tenable, I have developed what we understand to be a list of the top ten things that people may not know about

### Security Tools Working Together
This is the third in a series of posts that describe the use of Nessus on BackTrack 5. Previous posts covered how to activate Nessus on BackTrack 5 and how to integrate Nmap, Hydra, and Nikto with Nessus. In this post we will cover initiating Nessus scans from within Metasploit. Beginning with Nessus 4, Tenable introduced the Nessus API, which lets users programmatically interface with a Nessus server using XMLRPC. Zate Berg took the initiative to write modules in Metasploit that, among other things, can launch a Nessus scan and import the results into the Metasploit database. From there, we can find which hosts are vulnerable to exploitation, exploit

# Integrating Nessus with BackTrack 5's Tools

BackTrack 5, code name "Revolution", is a very popular Linux distribution used primarily for penetration testing. It contains a lot of different tools for scanning, testing, and exploiting everything from web applications to wireless networks. Since the creators of BackTrack 5 included such a vast array of tools, I thought it would be interesting to show how some of those tools can be integrated with your Nessus server to extend functionality and import results.

### The Benefits of Credentialed Scanning and Auditing
We've covered the advantages of credentialed vulnerability scanning and configuration auditing in previous blog posts, but I want to recap some of the benefits:
- Getting Around Firewalls - Whether you are scanning through network or host firewalls, credentialed scans require less ports to be open between the scanner and the target(s) and require less network bandwidth and target resources.
### Making It Easier
Convincing your systems administrators to allow credentialed scanning in your environment can be difficult at first. Administrators are typically reluctant to provide administrative level credentials r

# Comparing the PCI, CIS and FDCC Certification Standards
Ron Gula
June 23, 2011

As a vendor, Tenable has to demonstrate compliance in many different types of categories. The Payment Card Industry, the Center for Internet Security and US government's FDCC program all have certification standards and procedures for vendors like Tenable. Since Tenable is certified in most of these these categories (we're in the process of becoming an ASV), I though it would be interesting for our blog readers to share some of our insights into the differences and misconceptions between them.
PCI
The biggest misconception about PCI is that you need to be an Authorized Scanning Vendor (ASV) to be relevant in the industry. This isn't true, otherwise you would not see the focus

### Keeping Tabs On Patches
Let’s face it; we all have to deal with patches. Everyone from an IT systems administrator to your grandma has to face the challenges of patches. Whether you have a home computer that you use to browse the web, a phone that you occasionally check email from, or 10,000 enterprise desktops spread across three continents, you're dealing with patches. Regardless of your situation, you need to be able to answer two basic questions:
- Which patches are missing?
- Which patches have been successfully installed?
If you only have one computer in the house, it probably annoys you to some degree when it’s time to apply patches, indicating that you are in fact mis

# Hardening OS X Using The NSA Guidelines

### NSA Hardening Guidelines
The National Security Agency (NSA) has developed security hardening guidelines for various operating systems and technologies. I remember when I first started in information technology and used these guides to harden my Windows servers. I was met with mixed success; some systems would run better, and some would cease to function due to configuration changes. This taught me about my systems and their configurations, and knowing what your systems do and how they are configured is the true key to successful systems administration. Remember, the “guidelines” are just that, a guide to configuring and securing your systems. Ultimately, it is up to you to determine

I was recently talking to my good friend Ed Skoudis about computer security incident response. An interesting question he asks organizations that are in "incident response" mode is, "Do you run PsExec?" PsExec is part of the Windows Sysinternals’ suite of tools and implements a service that allows users to administer Windows systems remotely using the command line. More information can be found on the PsExec download page. It also contains functionality described as:
> "PsExec's most powerful uses include launching interactive command-prompts on remote systems and remote-enabling tools like ipconfig that otherwise do not have the ability to show information about remote systems."

# Plugin Spotlights: New Nessus OS Identification Plugins

April 29, 2011

The Tenable research team recently published a few new plugins that contribute to how Nessus performs OS identification. When scanning devices and systems I am always amazed at how many different services will hint at, or even flat out reveal, the operating system and version.
### OS Identification : HNAP
HNAP is the Home Network Administration Protocol developed by Cisco Systems. It is designed to allow remote support personnel to manage devices on users networks using a SOAP-based protocol. An unfortunate side-effect is the information being leaked across the network that can be accessed without authentication. A new plugin was developed to collect this information

Supervisory Control And Data Acquisition, or SCADA, generally refers to the computers that control industrial and infrastructure systems. These include systems found in power plants, nuclear reactors, commercial buildings and more. The last few weeks have seen another serious blow to the perception of SCADA security.
On March 21st, Luigi Auriemma posted to the Full-Disclosure mail list announcing his research and vulnerability findings in SCADA products from vendors such as Siemens, Iconics, 7-Technologies and DATAC. Auriemma’s post included links to 34 advisories ranging from overflows to denial of service. Due to the sensitive nature of SCADA systems and the resources they control, his resea

With today’s plugin updates, Nessus now has the capability to warn you of hosts that are being controlled by botnets or hosting links to known malware or phishing sites.
Nessus uses a list of botnet infected hosts that is updated daily to search for your scan targets and report if the host is a known botnet zombie or is in command and control node. This is done regardless of the plugins or credentials specified and does not require sending any packets to the host to perform this check. Such hosts have been previously observed as sending malicious traffic to third-party systems across the Internet or taking an active role in attempting to control or compromise hosts for the botnet.

Have you ever been charged to perform a security audit for a set of hosts that has been turned off? If those hosts have been configured to be “woken up” with a “Wake-on-LAN” packet, you can now leverage this capability with your enterprise Nessus scans. This blog entry describes how organizations that leverage Nessus or SecurityCenter to scan their infrastructure can audit systems that have been powered off.
The most important item that you need to configure your scans is the list of Ethernet addresses of the hosts you want to wake up. A host that is configured for Wake-on-LAN isn’t fully powered off. The Ethernet card remains powered on and if it receives a spe

Tenable is pleased to announce the release of Nessus 4.4.1! This is a point release (moving from 4.4.0 to 4.4.1), containing several enhancements and minor bug fixes.
From a user perspective, there is a new feature that allows the SYN scanner to be selectively throttled. A new setting, nessus_syn_scanner.global_throughput.max can be added to the nessusd.conf file. The option sets the maximum number of packets per second that Nessus will send during a SYN port scan (regardless of how many hosts are scanned in parallel).
In addition, several enhancements and bug fixes are included:
- When qdb_mem_usage is set to "High" (default), if Nessus fails to allocate enough memory to store the plugins DB, it switche

Over the past few months, fields in Nessus reports indicating whether or not an exploit exists for a given vulnerability have continued to evolve. We first announced this feature in October 2010 in a post titled New Nessus Feature: Public Exploit Availability. Ron Gula then wrote a follow-up post called ”If an exploit falls in the forest, does anyone hear it being patched?”, that described the usefulness of the information contained within the "Exploit available" and "Exploitable With" fields in Nessus plugins.
The Nessus interface has now received an update that will display the "Exploitable With" field directly in the report (prior to the latest version, this field was only conta

And the race is on to apply patches to the Microsoft Windows systems in your environment! One of the bulletins this month, MS011-04, fixes remotely exploitable issues in the IIS FTP service. To me, FTP falls in the same category as Telnet, which is "You should be using SSH instead". Despite the lack of security that FTP offers, it still appears to be wildly popular decades later. I performed some searches using "SHODAN", "The Computer Search Engine", which scours the Internet looking for open ports, services and banners. I told it to find systems with port 21 (FTP) open and got the following results:

I've recently been doing a bit of research into the history of Nessus. I discovered that the first version of Nessus was published in 1998, and any time software has been around for that long there are bound to be some myths and misconceptions that develop as fast as new features over the years. This post will explain some common myths and set the record straight.
You can read more about this topic in The Nessus Port Scanning Engine: An Inside Look, and Web Application Scanning with Nessus.
While we did not generate any large explosions for this post, I dove across the office, just because.

Note: This blog was updated in March 2021 to include additional guidance on how customers can address custom certificate authorities.
Do you know where all of your organization’s SSL certificates are and if they are providing enough protection to you and your customers? Nessus can be used to identify all SSL certificates in use, test if they are expired and with the advent of plugin # 51192, test that they have been securely signed by a valid certificate authority. This blog entry will review Nessus’s SSL certificate auditing ability and describe how plugin #51192 can help monitor your network for untrustworthy SSL certificates.

# Using Nessus For Host Discovery
Paul Asadoorian
December 9, 2010
4 Min Read
A Nessus user recently contacted me about performing a scan that would simply discover hosts on the network. This is a very low impact scan that does not look for vulnerabilities or enumerate ports. There are a few good reasons to run this type of scan:
Systems protected by a network or host-based firewall may only respond on a single port or to an ICMP echo request. Hosts that only respond to an ICMP ping will not show up in the default Nessus scan report. By enumerating these hosts you can include them in the report to show that scans were attempted but did not find any results, then determine if this is normal behavior or not.
Your internal policies may provide specific time windows whe

Recently, Tenable added exploitability reporting for Nessus. After performing a scan, results can be filtered to see which vulnerabilities have exploits available for them. In the report, you can even see which common exploitation tools have payloads for these vulnerabilities. This is a great way to help prioritize which vulnerabilities to fix first. However, it is not a great way to manage your network or decide whether to patch a system or not. Consider the following conversation that represents many I’ve had on this topic:
IT Auditor: Ron, we love the new exploit filtering feature in Nessus!
Ron: That’s very cool. What do you like about it?

### Default vs. Easily Guessable Credentials
There are several Nessus plugins that test various common username and password combinations. I tend to put these into three different categories:
- Common Credentials - Commonly used username and/or passwords that are valid regardless of the application or device type (e.g. username "root" / password "toor")
- Brute Force Guessing - User supplied list of accounts and passwords fed to Nessus via Hydra
There are 70 plugins

Tenable is excited to announce a new release of the Nessus vulnerability scanner! This is a major release (moving from 4.2.2 to 4.4.0) and includes several new features and enhancements, including the addition of scan scheduling and enhanced reporting. The GUI and web server have both been updated and will be released through the plugin feed. The enhancements included in the plugin feed will be backward compatible with Nessus 4.2, and some of the new features will be available in Nessus 4.2 via the plugin feed update. However all users are strongly encouraged to upgrade to the latest version to take advantage of all the new features.
The list below outlines the changes included in the 4.4.0 release

### Balancing Risk
Security continues to be a balance between providing users with features and mitigating risk. . Client-side vulnerabilities seem to be the hole that many of us are stuck spinning our wheels in.
This month Microsoft fixed a buffer overflow vulnerability in Word that resulted from the processing of RTF documents in security bulletin MS10-87. This has already received some immediate attention, primarily because Outlook can be an attack vector due to the preview pane automatically displaying the contents of file attachments. At some point, you have to ask yourself "How important is it for the users to use the preview pane in Micr

### Reconfiguring Access Points
Wireless threats come in many different forms, such as disclosure of cleartext credentials, breaking encryption schemes such as WEP and attacking wireless drivers on client systems. While you can extend the range of wireless signals, for the most part these attacks require that the attacker be in close physical proximity of the wireless network and/or client to execute. This is the primary reason why most organizations do not assign a high priority to defending against these attacks. There are far more attackers on the Internet than will be in close proximity to your wireless deployment.
However, something that worries me greatly are wi

When installing Nikto on Linux systems, here are a few tips:
As of Nessus v6 the command line utilities for running Nessus scans are no longer included. Customers are encouraged to use the Nessus API to implement command line base scanning, and a host of other features include uploading and downloading reports. Customers can find examples in the Tenable Discussion Forum, and in particular the post "Nessus v6 API Demo Scripts" and documentation.
To download Nikto and install it, use the following commands:
$ wget http://cirt.net/nikto/nikto-2.1.3.tar.gz
$ tar zxvf nikto-2.1.3.tar.gz
$ cd nikto-2.1.3
Run the following two command as root:
# mkdir /opt/nikto
# cp -r * /opt/nikto/

I am often astonished as to just how many vulnerability checks are included with Nessus. There is something to be said for the scope of the nearly 40,000+ plugins (the numbering of the plugins started at 10001). On October 19, 2010, Nessus plugin number 50,000 was published into the feed. Let's go back and take a look at some of the first plugins:
The "official" first numbered Nessus plugin in the feed is ColdFusion Multiple Vulnerabilities (File Upload/Manipulation) - Plugin ID 10001. I found some interesting information about this vulnerability:

A new feature was introduced with the latest update to the Nessus web server (2.0.0) and Flash interface (build 20100913A) to provide "exploitability" information to the user. Each plugin now contains a field that indicates whether or not a publicly-known exploit for the vulnerability exists:
The value will either be "True" if an exploit exists or "False" if an exploit is not publicly known. Nessus checks select sources for the presence of an exploit and updates this field accordingly. I purposely chose a "Medium" level vulnerability for this example, as exploits do not only have to be associated with “High” level alerts. In the above case, the vulnerability is a denial of se

### "Silent" Worms: Stuxnet
The vulnerability patched with MS10-061 is perhaps one of the most interesting we've covered in a "Patch Tuesday" post this year. The vulnerability was discovered when antivirus researchers at Kaspersky Lab analyzed malware called "Stuxnet". The malware was one of the first worms to use the LNK vulnerability, and contained code to exploit three other vulnerabilities, the print spooler vulnerability patched by MS10-061 and two other unnamed privilege escalation vulnerabilities that have yet to be patched. Its not everyday that we hear of malware in the wild exploiting 4 0-day vulnerabilities.

### Don't Fall Off The Stool
When I developed the course "Advanced Vulnerability Scanning Techniques Using Nessus", I wanted to mention some of the trade-offs we make when we perform vulnerability scans using different configurations. Nessus creator Renaud Deraison helped point out that it seems to come down to three factors: speed, intrusiveness and comprehensiveness. What I found was that these three factors were extremely important throughout the duration of the class, and I realize that for vulnerability scanning and vulnerability management, these factors must be taken into consideration.
"Vulnerability scanning is a balance between speed, intrusiveness and comprehen

### Zen and the Art of Nessus Web Application Scanning
Tenable’s research and development teams have been steadily adding new features and plugins to the web application scanning functionality in Nessus to detect web application vulnerabilities. These can be grouped into two categories:
- Known Web Application Vulnerabilities - Nessus contains over 1,700 plugins that can fingerprint and detect known vulnerabilities in web applications. Any plugin listed in the "CGI Abuses" or "CGI Abuses : XSS" plugin families is written to enumerate vulnerabilities that have been previously reported in a web application product (open-source or commercial). To enable these plug

### It’s All About the Information
> "There's a war out there, old friend. A world war. And it's not about who's got the most bullets. It's about who controls the information. What we see and hear, how we work, what we think... it's all about the information!"
- "Cosmo", From the movie "Sneakers" (1992)
The last part of the quote above always seems to play in my head during the course of an average day in information security. It really is all about information in many different aspects. One aspect I would like to highlight is collecting information about those who are attacking you. Specific information potentially useful to those defending networks and systems could be:

Tenable has authored a Nessus plugin (ID 46689) named “Cisco IOS Compliance Checks” that implements the APIs used to audit systems running Cisco IOS. This plugin is pre-compiled with the Nessus “.nbin” format. This provides ProfessionalFeed users a method of using Tenable provided .audit files, or their own audit policies, to audit Cisco devices to ensure compliance with corporate policy. This functionality provides a wide range of audit capability including ACL policy detection, service status, device access control and more.

This particular bundle addresses 34 vulnerabilities in Windows, IE, Office, .NET Framework, IIS and Sharepoint, a tie for the largest vulnerability count in a single Microsoft Patch Tuesday to date. The advisories include a wide range of vulnerabilities including code execution, privilege escalation, information disclosure, denial of service and cross-site scripting (XSS).
Among the vulnerabilities addressed in June’s updates are two issues that were recognized by Microsoft in February and April. Three of the ten updates have been given severity ratings of “critical” wh

With the release of Nessus 4.2.2 a new method of credential elevation has been included for Unix-based hosts that have sudo installed: “su+sudo.” This method allows you to provide credentials for an account that does not have sudo permissions, su to a user account that does, and then issue the sudo command.
This configuration provides greater security for your credentials during scanning, and satisfies compliance requirements for many organizations.
To enable this feature, simply select “su+sudo” in the “Elevate privileges with” section under the credentials/SSH settings as shown in the following screen shot:
Under the “SSH user name”, and “SSH password” tabs, enter the credentials that do

You may know the folks over at MITRE for their work on the CVE (Common Vulnerabilities & Exposures). Standards such as CVE help us track and document thousands of vulnerabilities released each year. Along the same lines, a new project from MITRE called CPE (Common Platform Enumeration) provides the public with a standard method to enumerate software:

### Microsoft's Language
No, I'm not talking about C# or Visual Basic, I'm referring to Microsoft's very own version of the English language ("Minglish"?). An example of the Microsoft variation on the English language is shown here:
> "The vulnerability could allow remote code execution if a user visits a malicious e-mail server."
We've addressed the "could allow" statement in a previous post (for example, changing your shoes “could allow” you to win the lottery). We've also addressed the "remote code" execution and dug into what that really means. In this case, it takes on a slightly different meaning from the traditional remote buffer overflow or client

The release of Nessus 4.2 included some interesting architectural changes as the complete Nessus installation was moved to a server based model. This means that all code, including the web-based client, now resides on the server. This provides the ability to update the Nessus client via a plugin update rather than having to install a new version of a traditional client locally on a workstation or server.
The first feature rolled out in this fashion came down in a plugin update released on April 20, 2010 (client build ID 20100416A and web server build ID 1.2.1 as seen in the "About" screen of the client). With this update, Nessus users could save a scan as a template to be used for multip

### It’s A Bird, It’s a DoS, It’s Remote Code Execution!
I've always cautioned people about the danger of disregarding vulnerabilities that are labeled as "Denial of Service" (Such as MS10-014 from February) for a couple of reasons. First, when a bug exists in the code that allows something to "crash", there is usually a potential that the "crash" could somehow allow for code execution (remember that a buffer overflow is just a controlled crash). Second, when code is being analyzed so that the bug can be fixed, the surrounding code is often analyzed to be certain there are no other bugs or vulnerabilities. This analysis could lead to the disclosure of other vul

### Misconfiguration can Lead to Compromise
As a former full-time systems administrator, I understand the pain of managing and maintaining systems. A significant amount of testing is often required to ensure that you have the correct configuration settings, not just in terms of security, but also for system stability. Once you have the correct configuration it is difficult to maintain consistency across the environment on an ongoing basis (especially across hundreds, or even thousands, of disparate systems). This problem crosses all platforms and Unix/Linux and Windows administrators alike share the same challenges. Some examples include:

Nessus users have a wide range of powerful options whose functionality
is critical to a successful vulnerability scan, but whose meaning may not be completely
clear. An example of this is the “Thorough tests” option. There is more to this
option than meets the eye and knowing how to properly use it will help you
customize your scan policies to your specific needs. By default, this option is
disabled; however, of the more than 34,000 plugins available with Nessus, over
900 behave differently if this option is enabled. This blog describes what the feature
does and provides some examples of where the option should or should not be
used.
The “Thorough tests” option is located in the s

### Security In The Cloud Is Still Just Security
A recent paper published in the International Journal of Services and Standards titled "A 'cloud-free' security model for cloud computing", written by Manal M. Yunis, outlines six security considerations for cloud computing. Upon reading the six considerations, I can't help but think that they do not present new challenges but merely rehash old ones. Let’s take a look at each of the six common cloud computing security considerations in more detail:

### Attacks Happen
There are many reasons why attackers may target your organization: they could be after your intellectual property, they may have political reasons or there may be financial motivations (if you have credit card data stored on your network). I've often heard people say, "Why would someone want to attack us?" The question should really be phrased, "Why would someone need to attack us?" Often you are targeted not because of who you are, but what you have. Google hosts email accounts that are interesting to certain parties. You may be a university with plenty of bandwidth or a business partner with a company who makes electronics that the a

### "What Am I Doing Wrong?"
I am often asked, "What am I doing wrong in regard to security?". This question is usually in reaction to some event, such as a failed audit, a network outage as a result of malware or worm or a breach that was detected in the environment. I ran into this situation while doing incident response for a large university. It was my job to monitor the network and respond to the major incidents that were occurring (it was also up to me to determine what was "major" and what was not). I worked with many different network and system administrators on campus to help them improve the security of their respective departments. However, this was an academic env

Embedded devices are often connected to a network with no regard given to security. The market has been saturated with devices such as web cameras, wireless routers, VoIP phones and more. Manufacturers are in a race to see who can produce the cheapest and most user-friendly device. Of course, when you make something cheap and easy to use, security is often one of the last considerations. We are left with consumer devices that come with default credentials, common web application vulnerabilities, and no encryption support on management protocols (HTTP vs. HTTPS, and Telnet vs. SSH).
The insecurity of embedded systems may not seem to be a big deal; what could someone possib

### Patch Tuesday Gives Birth to "Zombie Wednesday"
The Tenable research team spent the night writing 14 new plugins to check for the latest round of Microsoft patches. While many will have to schedule patch installations, those who run with full automatic updates enabled are theoretically all patched by now. However, it doesn't hurt to check with a quick Nessus patch audit.
### Microsoft is in Love With the Word "Could"
There are several terms used by Microsoft throughout their advisories that spread uncertainty about the risk of the vulnerabilities presented. The excessive use of the world "could" is one such example. In the MS10-002 bulleti

### Ease and Security Don't Mix
In the eternal quest to create easy ways for systems to communicate with people and other systems, embedded device manufacturers have created new protocols. One of the first was UPnP, or Universal Plug and Play, which has had its share of security problems. The latest protocol to emerge is called HNAP, or Home Network Administration Protocol. Its goal is to "allow advanced programmatic configuration and management by remote entities." The protocols primary purpose is to aid device manufacturers in supporting remote devices such as printers and wireless routers. HNAP allows remote configurations to be both viewed and changed remotely

Providing credentials to Nessus so that it can log into the systems being scanned is a very effective method of vulnerability scanning. It enables the scanner to provide a patch audit, perform local operating system identification, portscanning, and audit the configuration files present on the target. For web application testing, credentials allow Nessus to enumerate and detect vulnerabilities inside the application, ensuring that a larger percentage of functionality is tested. The following two videos cover how to perform both network-based credentialed scanning, and provide credentials for web application scanning using Nessus 4.2.

A customer recently asked us to provide a count of
patches issued in 2009 for various Unix and Linux-based operating systems. To
honor their request, we turned to OSVDB,
the Open Source Vulnerability Database. OSVDB covers over 60,000
vulnerabilities, spans over 26,000 products and has a powerful search engine
that can produce search results based on disclosure date(s), vendor and/or
product, CVSSv2 scores, references, vulnerability classifications and more.
When generating any statistic regarding vulnerabilities, it is important to
qualify the statistics and understand they are only as good as the data set
that generated them. While OSVDB does not have a complete data

### Stinky, Aged Operating System?
It’s that time of the month again - Microsoft patch Tuesday of course! This month I expected to research several different vulnerabilities, how they work, methods to detect them, etc. However, Microsoft is only patching one vulnerability this month. I can’t believe there is only one vulnerability this month! In any case, this month's vulnerability occurs in the way applications handle Embedded OpenType fonts. I was a bit puzzled as to why so much effort was going into font rendering until I discovered that it is common for web sites to implement different languages and have them display correctly to the end user (primarily fo

### Plugins, Glorious Plugins
In 2009, Tenable released over 8,100 new plugins (and the year isn’t over yet!). These plugins have covered several different types of vulnerabilities, including web applications, embedded systems, local checks for operating systems and much more. We polled Tenable employees in our research and content groups to find some of our favorite plugins released this year,and compiled the following list:

Another Tuesday, another round of security bulletins from Microsoft. Are you patched? Nessus contains credentialed local checks for all Microsoft security bulletins.
### "Specially Crafted"
I have always wondered what the term "specially crafted" really means. What is "special"? Merriam-Webster defines it as "distinguished by some unusual quality". "Unusual" is relative, and means that someone has defined what "usual" means. This is where we start to enter a grey area. How do we determine what is "special" if the "usual" is not clearly defined? In this case, I'm talking about RFCs, the documents used to define what "usual" means with respect to Intern

### Severity Is Multi-Dimensional
Vulnerability scanning tools, such as Nessus, can produce reports and assign discovered vulnerabilities a severity rating. The problem I always had with these reports was in evaluating these ratings. Like many other administrators, I found that vulnerabilities with “high” severity ratings always caught my attention first. Sometimes it would take a week’s worth of effort to evaluate and remediate the high- severity vulnerabilities. Although I knew that I should also investigate the low or medium severity level alerts, I never seemed to have time. These were most often given a low priority when it came time to assign tasks a

### Another Milestone, Nessus 4.2
Long-time users of Nessus have probably noticed that significant improvements have been made over the past several years. For example, Nessus version 3 introduced many performance enhancements due to an overhaul of the NASL interpreter. Nessus version 4 introduced several more improvements, including multi-threading and 64-bit support, in addition to unifying the code base across multiple platforms (Windows, Linux, and Mac OS X). Tenable is proud to introduce the next evolution to the Nessus vulnerability scanner with version 4.2, which includes several enhancements including an all-new Flash-based interface.

Another Tuesday, another round of security bulletins from Microsoft. Are you patched? Nessus contains credentialed local checks for all security bulletins, and a network-based uncredentialed check for MS09-064.
### Severity is a Matter of Perspective
What struck me as interesting this month are the severity ratings. Microsoft publishes these ratings as a guide to help customers evaluate the vulnerability risk. In many cases, they seem to be doing their customers a disservice. For example, a remotely exploitable vulnerability in Microsoft Word or Excel could be leveraged by attackers to compromise desktop systems. These types of vulnerabilities are frequently exploited by attackers and penet

### Windows 7 - a "Shiny" New Operating System
Most experts agree that producing Windows Vista was not a shining moment for Microsoft. It was plagued with problems from the start, including performance and stability issues. Many organizations flat out refused to upgrade from Windows XP to Vista, deeming it not worth the investment of resources and overall cost of the upgrade. Windows 7 is now here to replace Vista and XP, and the reviews have been positive from the beginning. In my own environment, I stayed away from Vista and jumped right into Windows 7. I believe that as Windows XP comes to its end of life, Windows 7 will step right in to replace it, despite the upgrade costs. Most pe

Scanning web applications that require credentials can be a bit tricky as different applications may handle the authentication process in different ways. Nessus has configuration options that will allow you to define the authentication parameters for each application. Nessus also allows users to define pages that are not to be accessed during the web mirroring process, such as "logout.php", which prevents Nessus from being logged out of the application.

### Defeating Zombies
Attackers have a number of avenues leading directly into your network, and more importantly, into your data. Each week I read about new data losses, phishing scams and the release of hundreds of new vulnerabilities and exploits. Organizations are employing a rear guard action that is not necessarily tuned to today's attack techniques.
Tried and true defensive measures such as firewalls, anti-virus software, Intrusion Detection Systems provide "operational security", but even if this is running flawlessly, it is typically not enough. Security programs need to evolve with the latest attack trends and Internet technologies. A great blog post by Tim Mughe

Last week Microsoft released 13 security bulletins covering 34 vulnerabilities, much to the delight of overworked system administrators who now have to roll out and test the patches in their environment. Organizations are most likely at different stages in the patch deployment process, some may still be testing and some may have the patches rolled out to the entire environment. What all organizations have in common is the need to verify that patches have been installed properly. Nessus has several features, including credentialed scanning and plugins that list missing patches and can assist in the patch verification process.

# Microsoft "Patch Tuesday" - The Aftermath
Paul Asadoorian
October 19, 2009

### Black Tuesday
This month Microsoft released 13 new security advisories. While 13 sounds like a moderate number, digging into each of the security advisories reveals that each one actually patches multiple vulnerabilities, bringing the grand total to 34 individual vulnerabilities. Couple that with the recent Adobe announcements disclosing 29 vulnerabilities with the Adobe Reader product and release of the associated patches and administrators have their work cut out for them (note that Nessus plugins have been released to detect these vulnerabilities, refer to plugin id 42119 and 42120). Assessing the risk for your organization when there are this many patches in common softwar

The current version of the Nessus 4.2 client and server is labeled as "ALPHA1" and is still very much in development. However, the new client interface has been completely overhauled, moving to a web-based interfaced. This introduces a substantial change for the end user without significantly changing the features they are accustomed to. We wanted everyone to get a sneak preview of the new version, see some of the new features and give feedback early in the development phase. A short video has been uploaded to our new video channel on You Tube:
We would appreciate feedback and suggestions on how to make the new NessusClient even better. You can visit the Nessus disc

# Scanning Web Applications That Require Authentication
Paul Asadoorian
September 21, 2009
9 Min Read
Web applications that manage sensitive data are usually protected with either basic or form-based authentication. Nessus can be configured with the appropriate credentials for these authentication schemes as they relate to web application testing. This post covers these authentication schemes in-depth, and explores some of the potential problems you may experience when scanning with credentials and how to overcome them.
### Basic Authentication
For web applications, or sections of web applications, that require basic authentication, you can enter one username and password pair that Nessus can use each time it is prompted for credentials. On the "Advanced" tab in the

### Remote "0Day" IIS FTPd Exploit
On September 1, 2009 security researcher "kingcope" released an exploit for a previously undisclosed vulnerability in the Microsoft IIS 5.0/6.0 FTP Server. Microsoft had not been made aware of the problem, therefore there is no patch available at this time. The exploit is known to work against Windows 2000 servers running IIS 5.0 and 6.0, and rumored to cause a denial of service against 6.0 on Windows 2003.
### Prerequisites for the Vulnerability
A system is vulnerable if anonymous FTP is enabled (however, this may also work with valid credentials) and there is a world-writable directory on the system

### A "Rogue" Access Point
Detecting and preventing rogue wireless access points is a major concern for many organizations. It is important to ensure that all wireless networks are established and configured in compliance with the organization’s policies and standards for wireless networks. The problem is that it is very easy for a user to establish a rogue wireless access point either inadvertently or deliberately. A wireless access point plugged into your network will typically have an Ethernet connection tied into some part of your LAN, and provide wireless access to an attacker that bridges the connections. Users could put one on the network for convenience, or a company pro

Scanning web applications with Nessus offers the end user several new configuration options in the Nessus client. You should take into account:
- Number of web servers and applications being scanned
- Size of the applications (e.g. how many parameters does each CGI application have?)
- Depth and scope of the scan with respects to the type of tests being performed and how exhaustive they should be
This video demonstrates how to setup Nessus to scan a web application using the new options:

### Security and usability do not mix
PHP has a horrible reputation in the security industry based on a long history of vulnerabilities and vendor resistance to fixing them and improving security practices. It suffers from a common problem; the technology is designed to be easy to use, and therefore a high level of security is difficult to achieve. Many who are new to web application programming use PHP, but often do not pay attention to security. In addition poor developer coding practices, PHP itself presents many vulnerabilities in its default configuration even when seemingly harmless coding practice is in use. This leaves a plethora of vulnerable a

### Finding the Needle in the Haystack
It is important to know what applications and services are in your environment to properly evaluate risk. Recently, a question was posed about detecting phpMyAdmin, a popular application for managing MySQL databases. We've previously explored how this application could be used to take over a system, demonstrating the risk this application may pose. There are several actions to perform when searching for applications on your network (in this case we are searching for a web application).

As of Nessus v6 the command line utilities for running Nessus scans are no longer included. Customers are encouraged to use the Nessus API to implement command line base scanning, and a host of other features include uploading and downloading reports.

Backtrack 4 is a Linux distribution and “Live CD “ (a bootable operating system on CD or DVD) that is designed for penetration testers. It contains a wide array of tools for performing penetration tests, web application assessments and reverse engineering. It is a simple process to get the latest version of Nessus installed and running on Backtrack 4.
There are two ways to create a Backtrack 4 bootable drive: create the partitions manually or run the install.sh program. I highly recommend running the install.sh program to perform a full installation of Backtrack 4. While you can boot the distribution from a manually partitioned CD or USB thumb drive, the file system is only temporary and you

Your organization's network is a never-ending source of vulnerability information. New systems and applications are constantly being added, making the job of consistent vulnerability identification and risk management difficult. Tenable provides several tools to assist in this process. Nessus, combined with the Security Center, can provide detailed information about the vulnerabilities in your environment. The problem that many administrators face is that they are not always successful in getting management to recognize problems and provide resources for remediation. This blog post describes some tactics I have compiled over the years to help expedite this process.

Below is a breakdown of how the event was organized, including several examples of attack and defense techniques we performed.
### Day 1 - The Game
The game is divided into two areas; one for attackers ("Red Cell") and one for defenders ("Blue Cell"). The Blue Cell is further divided into teams, each defending a set of machines that represents a real company. The attackers can use whatever tools they have at their disposal. The defenders must defend everything from mock SCADA systems, VoIP, Microsoft Exch

Traditional buffer overflow vulnerabilities require specific conditions to be met on the system, payload to be written for the target platform and an exploit smart enough to get around system execution protections in memory. Some of the most dangerous exploits rely on vulnerabilities that can be triggered in a varying number of conditions and circumstances. A far more reliable approach is to take over a process or manipulate a protocol to gain access to the system that does not require that a buffer overflow vulnerability be present.
This brings us to the HP Discovery & Dependency Mapping Inventory (DDMI) agent, which runs on a variety of platforms, including Windows and Linux,

Browsing the web is increasingly hazardous, especially given the recently released vulnerabilities and associated exploits. It’s interesting how the vulnerabilities are being referred to as "remote". While they are remotely exploitable, there are differences in how they are executed. One form of remote exploit requires no user interaction. A process listens on a port and is exploited over the network without the end user having to perform any action. The ActiveX vulnerability referenced in this plugin is remote, but does require that the user have a web browser loaded and actually be browsing the web. The exploit can be embedded into different web pages and ex

Attackers have access to a great deal of public information about your organization. Public web sites, domain records, routing information and several other sources can provide an attacker with useful information to launch attacks. Public documents posted on your web site contain metadata that can be very useful to an attacker. Metadata, in the context of the documents created within your organization, is information about the document itself. This can include who created it, their email address, the creation date, the software used to create and publish it and the software version and platform. This information can then be used to create client-side attacks that specifically target individ

### Implementing Different Scan Types
Often, Nessus and Security Center users ask how often they should run a vulnerability scan, and what kinds of scans should be run. In a previous post we explored some of the different scan types, including network checks, local checks and configuration auditing. I often encourage people to run all three types of scans against their network with different frequency. All three types provide interesting and useful results that should be included in your vulnerability management program. In this post we will explore the differences, and benefits, of running the first two types of scans mentioned: network-based scans and local che

### It’s the Small Things
Embedded systems continue to be overlooked in many environments, but often can present as much risk, if not more, than other systems on your network. Every enterprise has some form of an embedded device, from printers to routers and switches, that exists on the network and exposes services that could be exploited. Some recent examples include:
- HP Printer Directory Traversal - Printers are found in every enterprise network, and while thought to be limited in functionality, can present great risk to your sensitive information. A recent directory traversal vulnerability underscores this risk. Since most do not bother to harden the printers, man

Security breaches can come from those you least suspect. Have you ever wondered what would prevent a malicious insider from obtaining privileged credentials during an IT audit? It would be a simple matter of just setting up a Linux or Windows box with a sniffer or backdoor to grab the domain or root password during the audit. Tenable has written Nessus 3 and Nessus 4 to take advantage of underlying protection mechanisms in SSH and Windows authentication protocols to limit your exposure to this type of attack.
This blog entry describes how you can securely audit your Unix and Windows hosts to limit exposing these credentials to an insider and also how to use Metasploit t

A friend of mine, who was preparing to teach a workshop that included information about Nessus, recently asked: "What are the top three things you would tell people about Nessus?" Below is a more detailed version of my response:
1) Network Scanning - With over 28,000 plugins, Nessus has some excellent coverage in terms of vulnerability scanning for your systems and network. When running a network-based scan it is important to tune it appropriately. Look at the different plugin families and enable the ones that you think are most relevant. In addition, review the Advanced options for your scan. If you are performing web application testing, take a look at the Advanced options global va

### Not All Vulnerabilities Are Created Equal
We recently asked a select group of Nessus users which Nessus plugins provide the most interesting results for a given scan. This is a great question because you can often find patterns in the types of vulnerabilities that contain characteristics such as ubiquity and ease of exploitability. Several of the favorite plugins that penetration testers see during scans have to do with default or missing passwords that give an attacker instant access to the exposed service. The good news is that this type of vulnerability is usually easy to fix . Using Nessus makes this type of vulnerability easy to spot in your environment.

# Scanning Multiple Apache VirtualHosts With Nessus

Web sites have a way of evading vulnerability scanners in the form of virtual hosting. It is a common practice to host multiple web-sites (and associated applications) on a single web server using only one IP addresses. This causes problems for vulnerability scanners, including Nessus, as they look for vulnerabilities on the single IP or hostname provided. The remote server directs this traffic to a specific virtual host or web application, leaving a considerable amount of virtual real-estate untouched. The problem is that Nessus has no easy way to enumerate the domain names or additional IP addresses associated with a given system. Scanning every hostname, domain name and IP a

### When Denial of Service Become Remote Code Execution
When vulnerabilities are discovered, they are classified by various organizations using different methods. For example, CVSS scoring uses an algorithm to determine a severity rating from 1 to 10. This rating has been adopted by the NVD (National Vulnerabilities Database) and is used by Tenable to provide scores within the Nessus plugins. Sometimes a vulnerability is announced and its original rating is set as moderate or low. This is frequently the case with Denial Of Service (DoS) vulnerabilities as they allow an attacker to disrupt services but not gain remote access to the system. However, sometimes an advisory describes a vulnerability t

As of Nessus v6 the command line utilities for running Nessus scans are no longer included. Customers are encouraged to use the Nessus API to implement command line base scanning, and a host of other features include uploading and downloading reports. Customers can find examples in the Tenable Discussion Forum, and in particular the post "Nessus v6 API Demo Scripts" and documentation.

While Nessus has traditionally been a network vulnerability scanner, it contains quite a bit of functionality that can be used to identify vulnerabilities in custom web applications. This is not to say that Nessus will replace your favorite web application testing tool (or methodology), but it does provide useful information that can be used as the foundation for web application assessments or to indicate that deeper testing is warranted.
You can read more about this topic in The Nessus Port Scanning Engine: An Inside Look, and Web Application Scanning with Nessus.

### Stacking Up to CIS Benchmarks
The Center for Internet Security (CIS) establishes consensus benchmarks for a large variety of applications and operating systems. These benchmarks are a valuable aid to evaluate the security of your systems. Tenable has produced a number of Nessus audit files that have been certified by the Center for Internet Security to perform audits against the CIS standards. These audit files are available to ProfessionalFeed and Security Center customers through the the Tenable Support Portal.
To use these audit files, you will need to provide Nessus with credentials to login to the target host to compare the configuration against the CIS standar

### Conficker Attacks UPnP
The Conficker worm behavior has been analyzed by many security professionals who have shared their findings with the community (the paper from SRI is a great example). One of the common findings is that Conficker will connect to the local route/gateway via UPnP and make changes to the firewall, if the firewall supports unauthenticated UPnP. If so, it uses UPnP to open a high numbered port in the firewall, allowing access to that port from the Internet. It then opens the same port on the infected host, and uses it to distribute the worm further across Internet. The use of UPnP as well as insecure UPnP devices can be detected by Tenable's Nessus and PVS products.

The effectiveness of the Payment Card Industry (PCI) standards to secure systems responsible for credit card transaction processing is a question of debate among information security professionals. Regardless of the hype or negativity surrounding PCI, it remains a requirement for many organizations to follow. Nessus has built-in PCI-DSS compliance checks that compare scan results with the PCI standards and produce a report on your compliance posture. It is very important to note that a successful compliance scan does not guarantee compliance or a secure infrastructure. Compliance scanning is just one tool to be used as part of a comprehensive pr

Tenable has published official performance comparisons between Nessus 4, Nessus 3 and Nessus 2. We strongly encourage anyone interested in performing this type of performance analysis to follow the comprehensive methods we used in testing. The major findings of our testing include the following:
- Nessus 4 was up to five times faster than Nessus 3 on Windows.
- Not only does Nessus 4 use less memory, its shorter scan times reduces processing time.
- Nessus 4 is ten times faster than Nessus 2.
Of course, every network is different and quantifying performance for a network scanner is not an easy task. While we found the performance gap to be quite significant in our testing, results may not be typica

### XSLT Reporting
A new feature in Nessus 4 is the ability to use XSLT stylesheets to create custom reports. The stylesheets read the .nessus XML file and allow you to create a number of different report styles, such as HTML and CSV, as well as extract or sort specific data from the scan results. Nessus 4 comes with several built-in stylesheets that can sort results and display a report based on several criteria, including:
- Sort By CVE
- Sort By IP Address
- Sort By Port
- Sort By Vulnerability
You can use this feature in conjunction with the report filtering to more easily create custom reports.

# Configuring Nessus To Scan Through Firewalls

Note: This 2009 blog includes some outdated information. For the latest guidance on Nessus scans, please read our updated blog, "4 Ways to Improve Nessus Scans Through Firewalls"
### Nessus Scanning Through Firewalls
A number of factors can inhibit a successful Nessus scan: busy systems, congested networks, hosts with large amounts of listening services and legacy systems with poor performance all contribute to scan failure(s). However, firewalls (or other types of filtering devices) are one of the major causes of slow or inaccurate scans. Firewalls are essential for an organization’s perimeter protection and internal network segregation. Host-based firewalls are now common on bo

# Root Is Just A Few Clicks Away
Paul Asadoorian

Default vendor logins and passwords are a common security issue that Nessus can scan for. Some of these default accounts can pose a serious security risk, depending on the type of access they permit. Nessus plugin id 35029 ("Dell Remote Access Controller Default password (calvin) for 'root' account") is a great example of this. It looks for a default username and password present on DRAC (Dell Remote Access Controller) devices which provide remote systems management for Dell servers.
This is a common practice for many vendors: instead of having the end user create a password during the initial configuration of the system, the vendor assigns a default value. The default passwords are often poste

# nessuscmd Tip: Finding Open SMB File Shares
Paul Asadoorian
April 1, 2009

Penetration testers spend a lot of time searching for software vulnerabilities, such as buffer overflows or SQL injection. However, there are many other ways in which networks and systems can present vulnerabilities. Open SMB file shares can disclose sensitive information about an organization: I've found everything from student grades to bank account numbers using this technique. A great way to check for the presence of open SMB shares is to run a quick Nessus scan from the command line as follows:
```
# ./nessuscmd -U -p139,445 -V -i 10396 192.168.1.0/24
```
The flags used in this command perform the following functions:

The Tenable research team has been steadily working on creating accurate checking for Conficker infected hosts. Over the weekend researchers Felix Leder and Tillmann Werner of the University at Bonn released details on how to detect Conficker using network-based checks. This checking methodology was used as a basis for Nessus plugin 36036 as well as the Nmap NSE script created for the same purpose.
However, last night the Tenable research team discovered that the methodology employed to detect Conficker was missing infected hosts. The Nmap team independently noticed a similar problem, Leder and Werner were notified and updated their own checking tool, a Python based program called

# Detecting Malware Distribution With Nessus
Paul Asadoorian
March 31, 2009

Many of today's latest worms and viruses are using interesting methods to propagate across the network. For example, the Conficker.A / Downadup worm sets up a web server for victims to connect to and download a copy of the malware. What I find interesting about this method is that no matter what request is made to the HTTP server, it responds with a Microsoft executable file. Nessus detects such an HTTP server with plugin id 35322 "HTTP Backdoor Detection":
Note that Nessus performs service detection to discover applications running on non-standard ports. The port displayed in the above example (15871/TCP) is chosen at random, so be sure your scan is configured to run against all 6

### Getting In The Middle
Un-patched and out-of-date software is a common attack vector for penetration testers and attackers alike. Applications such as Adobe Reader and Microsoft Office are popular targets due to their widespread use on Windows systems and user’s willingness to click on just about anything. They both have the ability to perform self-updates, similar to the operating system, but limited to one particular software package. However, what happens when the software update process itself is insecure? Enter a program called "evilgrade", which exploits this process to install software of an attacker's choosing. For this attack to succeed, the victim machine must be the victim of

### Passive Detection
Monitoring networks for potential security violations can uncover some interesting events and surprising aspects of applications.
Base64 encoding is used by many applications to "obscure" the password when it travels across the network. Base64 encoding does not implement a cryptographic algorithm to protect sensitive information, yet is often used in many networks and end-user applications.
The Passive Vulnerability Scanner (PVS) has a rule to detect clients that are sending authentication credentials (username and password) in Base64 format:
Using the information provided by PVS, we could construct a very short Perl command to reveal the plain-text p

# Scanning Vulnerable Linux Distributions With Nessus
Paul Asadoorian
March 18, 2009

A challenge for many penetration testers is to find a vulnerable system they can use to test their penetration testing skills and tools before they use them against paying clients. I recently found a distribution called "Hackerdemia", a Slax-based Linux distribution containing several vulnerabilities, including un-patched software, mis-configured services, default passwords and a few other surprises. My goal was to bring up the distribution in a virtual machine, assign it an IP address using host-only mode and scan it using Nessus.
This will provide:
- A standard platform to test that my Nessus installation is functioning properly
- A place to test different Nessus plug-

# Misleading Patch Audits

I often tell Nessus users that patch auditing is more efficient and accurate than network scanning. And for the most part, this is absolutely true. However, there are several cases when patch auditing, or a lack of understanding of how patch auditing works, can actually give you bad data. This blog will describe the many subtle nuances to conducting patch audits.
Where do patches come from?
When I have the opportunity to interview potential new employees for Tenable, I often ask many questions about the differences between un-credentialed network scanning and credentialed patch auditing. I’m usually looking for a good grasp on the vulnerability disclosure process as well as operating system internals. A

(Note: This Blog was originally released in 2007 and was updated in March of 2009 to reflect an additional form of OS detection based on HTTP banners.)
Tenable's Research group recently introduced a highly accurate form of operating system identification. This new method combines input from various other plugins that perform separate techniques to guess or identify a remote operating system. This blog entry describes this new process and shows some example results .
Why a new process?
Two reasons.
First, although we feel that TCP/IP fingerprinting to guess a remote network stack is useful, there are too many variables and limitations involved to be considered 100% reliable

Earlier this year, Michel Arboi wrote a blog post explaining how to use Nessus to call Nikto and incorporate the results into Nessus output. Most newcomers to Nessus have enabled the nikto.nasl wrapper only to find it produced no output. Some Nessus users have found various ways to ensure Nikto was called correctly and the output displayed. Others chose to run Nikto separately for various reasons. The following guide will explain how to easily configure Nessus to properly call Nikto. This will allow you to save considerable time, especially on scans against a large amount of systems.

Nessus plugin #33523 "Network Camera Detection" will alert if it encounters a web page that belongs to a WebCam.
Typically, these web pages are not password protected and on ports other than port 80. If it is not password protected and not behind a firewall, it may be allowing unauthorized users from your organization, or even users from the Internet to view and/or listen to activity and conversations in the viewing area of the cameras.
Below is an example screen shot of this plugin being active during a Nessus scan.
The plugin does not require credentials, but is dependent on having its scan target the web server port if it is running on something non-standard, such as 8000.

# How to audit an Internet Facing Server with Nessus
Ron Gula
April 23, 2008
7 Min Read
Very often, Nessus is used by MSPs, consultants and IT security staff to test the security of an Internet facing server. Occasionally, we see the default settings of Nessus, which are optimized for a credentialed internal LAN audit, used to audit an external server. Although this usually results in a majority of the vulnerabilties being identified, Nessus can be configured to work a bit harder for these types of scans. This blog entry details some different strategies and scan settings that can be used to perform a more complete audit of an Internet facing server.

Ten years ago today, I announced the initial public release of Nessus on the bugtraq mailing list. The initial version would run only on Linux and was bundled with 50 plugins (vulnerability checks) written in C. At that time I was 18 and I had no idea I would still work on it years later (or that anyone would actually use it). A lot of great things happened during these years, and I would like to comment on the ten things which really shaped Nessus into what it is today.
1999 : The existing plugins were all switched from C to NASL.
In early 1999, I had done some work on a small engine called pkt_forge, which was meant to be a packet forgery tool (Net::RawIP did not exist at that time, so forging

# Scanning Network Printers and Novell NetWare Devices
Ron Gula
March 31, 2008

Historically, active vulnerability scanning of network printers and older Novell NetWare servers could be problematic. Sometimes a simple port scan with any type of auditing tool would cause a network printer to print paper, crash or interrupt real print jobs. Similarly, older Novell NetWare installs were also subject to crashing when having their servers fingerprinted.
Based on the feedback from the Nessus user community, Tenable implemented two scan options for Nessus that can limit how network audits interact with these technologies. These scan options are labeled:
- Scan Network Printers
- Scan Novell NetWare hosts

# Reverse NAT Detection With Nessus
Ron Gula
March 19, 2008

Nessus plugin #31422 named "Reverse NAT/Intercepting Proxy Detection" enables Nessus users to scan remote IP addresses and determine if they are forwarding multiple ports to different internal systems. This is sometimes also known as an Intercepting Proxy Server.
For example, if a user has configured a firewall or router to send SSH traffic to a hardened FreeBSD server, while sending RDP traffic to a Windows 2003 server, a remote Nessus scanner would be able to identify this.
The plugin can accomplish this sort of audit by comparing the OS fingerprinting results for each targeted port. If they are different enough, the plugin concludes that there is a reverse NAT involved. When using this plugin,

This blog entry marks the 200th post for this blog. I've been very pleased with the content we've created for our Nessus users and customers. The feedback I've received is that the content here is useful to information security practitioners from all walks of life.
Tenable recently released Nessus plugin #30000. This means that there are roughly 20,000 plugins (although some have been retired) in the current archive. Raw counts of vulnerability tests are very deceiving, however we feel very strongly that crossing this plugin ID count is a milestone worth noting.
We try to be very open about which checks are available by providing a public RSS feed of new plugins, dynamically listin

The Nessus Client 3.0 introduced a new format for Nessus scan policies, targets and results. This is known as the ".nessus" format. This blog entry discusses the advantages of this new file type and includes links to recently published technical documentation about the format and layout of the file.
Unified Scan Targets, Policy and Results
Historically, Nessus daemons and clients supported various file formats for scan configurations as well as scan results. When Tenable designed the new file format, we wanted to unify these into one file. This allows for rapid and accurate reproduction of a previous scan as well as understanding what a scan was looking for to begin with

Tenable's research group has released several hundred new plugins for Nessus in the last few days. One of them in particular is very useful for Solaris environments.
Plugin #29217 enumerates all installed software packages on Solaris operating systems. It leverages SSH credentialed scanning to obtain these results.
This plugin joins similar plugins for Windows and Unix that leverage a variety of credential types, even including software enumeration via SNMP for Windows if you have such a network.

As part of the more than 17,000 plugins available in the Nessus Direct and Registered plugin feeds, many of these look for common user name and password combinations. They will attempt to find administrator accounts without passwords, simple passwords and vendor defaults. Although these checks aren't performing an exhaustive brute force password audit, they may cause enough login failures to "lock out" operational accounts.
Tenable's research group recently introduced logic into the body of the Nessus plugin checks to prevent guessing of accounts. If auditors are running Nessus in a sensitive environment, they can now easily disable the types of plugins which could result in login

The Remote Desktop Protocol is also sometimes referred to as Terminal Services. This protocol allows remote users and administrators to view the desktop of a Windows system offering this service to control the mouse, keyboard, run applications and otherwise run the system remotely.
Being able to communicate with RDP (which runs on port 3389) to
determine the Windows operating system is very useful. Windows systems

By visiting the plugins summary page, Tenable publicly displays our latest signature count and how many unique CVE and Bugtraq IDs are currently covered. What I'd like to do in this blog entry is to move beyond the raw "counts" of vulnerability checks and provide some insight into what these numbers mean.

Nessus 3 UNIX scanners have the ability to save all of their generated packets as a convenient libpcap compatible file. This means you can save your scans and view them under applications such as TCPDUMP or Wireshark. Please note that this feature is not available on Nessus 4.
Why is this Useful?
There are many reasons to do this.
Having a network trace can greatly assist in diagnosing your environment as well what Nessus is attempting. Tenable's support group often encounters customers who are scanning hosts that are firewalled or are being screened with an intrusion prevention system which is spoofing responses. Having exact packet logs of what is occurring can help diagnose the resul

There are many consultants that use Nessus to scan a customer network for vulnerabilities and report a laundry list of security issues which need to be fixed. Another valuable service that can be performed by a consultant is to audit where sensitive data resides in an organization and what sort of access can be gained to it. This blog entry discusses what can be accomplished with the Nessus scanner and what additional types of data analysis can be performed with the sensitive content checks available with the Nessus Direct Feed.

"Can you scan one of our hosted sites?" he asked. A short while later, especially after asking the right sort of legal questions, we were looking at the results of a non-credentialed Nessus scan for a high traffic web site.
His web site didn't have any "application" content and hosted static HTML web pages. The only odd thing to note was an SSH server found on a very high port.
"Is that bad?" asked my friend.
"Well, it doesn't have any publicly known vulnerabilities." I said.
"So that's good, right?".
I told him I had two thoughts.

The BETA of Nessus 3.2 includes support for a new command line method to invoke quick Nessus scans. This blog entry details some interesting examples for port scanning, operating system identification, testing of a certain bug and testing Windows and UNIX credentials using the nessuscmd tool.
'nessuscmd' Usage
Simply running the command (located in your ~/bin Nessus install directory) will show you the usage. New features and settings may be added before this product is officially out of BETA.
Command line options exist for:
- Port Scan options
- Selecting Vulnerabilities
- Providing UNIX and Windows Credentials
- Scan settings (such as 'max-hosts' or using a remote Nessus daemon)

Tenable Network Security's Research staff recently added the ability to use LanMan/NTLM hashes as a form of credentials for Windows audits. If you use Nessus as a penetration testing tool, this allows you to take the hashes you have obtained with pwdump, lsadump, Cain, .etc, and use them to perform Nessus audits.
Leveraging Hashes and Nessus for Penetration Testing
Below is a screen shot of adding a hash to a Nessus scan policy:
Hashes are long strings of ASCII codes. The hash should be placed in the password field of the Windows credentials scan policy.
If the obtained hash has the correct credentials, you will be able to perform an audit of the Windows host and possibly other hosts on t

Today, Tenable released Nessus 3.1.4 beta. Here are the main changes compared to Nessus 3.1.3 :
- 64 bit OS builds for Debian 4 and Red Hat ES 5
- Fedora Core 7 build
- Improved support for IPv6. In particular, the functions get_local_mac_addr() and get_gw_mac_addr() work when dealing with an IPv6 host
- Fixed a bug related to the maximum number of TCP sessions set in parallel, which would cause nessusd to use more CPU than what is necessary
- Added several fixes in the NASL interpreter. In some cases, a copy-on-write operation would not be detected properly thus leading to incorrect modifications of some variables
- Fixed a bug in nessuscmd which would not be able to use the local nessusd d

# Nessus 3.2 BETA - IPv6 Scanning
Ron Gula
April 16, 2007

Nessus 3.2 will support scanning of IPv6 addresses. The current BETA (released as Nessus 3.1.3) can be used to perform scans of IPv6 addresses. This blog entry shows how to use the current Nessus 3.2 BETA to perform such a scan from the UNIX command line.
Why Scan for IPv6 Addresses?
More and more operating systems are shipping with IPv6 enabled by default. Both Vista and OS X ship with IPv6 stacks. The presence of IPv6 on your network may dramatically alter how computers communicate with each other and connect to the Internet. Communication that occurs over IPv6 may not be blocked by local or network firewalls, observed by network IDS or even correctly logged by your SIM.

Tenable's research group today released a check for Nessus which discovers systems not-running NTFS file systems. For example, a system running on top of FAT32 would be detected by this plugin. The plugin is named "Insecure Logic Drive FileSystem" and has a Nessus ID of 24871.
If you have a Windows Server system not utilizing NTFS, then there is very little security offered at the file level. NTFS offers the ability to set permissions on user files and folders and also makes it more difficult to gain access to system files.
The check considers every file system on the remote Windows server, not just those being shared over SMB.
This check is accomplished through Nessus 3 Windows WMI queries and is currently avai

Many organizations have IT configuration polices that require CDs and USB drives to be disabled. This blog entry discusses a simple way to use a Nessus 3 .audit file to test a Windows 2003 server for the correct registry settings that disable "AutoRun" of programs on CDs as well as disables USB drives.
Windows 2003 Registry Settings
On Windows 2003 servers, the following registry setting controls "AutoRun" for CD drives:
HKLM\SYSTEM\CurrentControlSet\Services\Cdrom
If the item "AutoRun" is set to zero, then the system won't run CDs when they are inserted into the server. Below is a screen shot, with the "AutoRun" item circled, of a Windows 2003 server's r

On January 3rd, 2007, Tenable's research group released a NASL script (plugin #23971, currently available to Direct Feed and Security Center customers) to test if a scanned host is on a different logical network, but also on the same physical network. If this is the case, your network may have a potential security issue, as IP based access control filtering may not be effective. This blog entry discusses what the plugin does, why this is important and comments on general firewall and access control auditing with Tenable solutions.

# More Flexible Assessments of Windows ACLs

Tenable recently increased the flexibility of performing configuration assessments of Windows access control lists (ACLs) with the Nessus compliance checks.
Previously, an ACL policy could only be built with exact understanding if it were "inherited" or "not inherited". For large numbers of checks, it might not make any difference if an ACL were inherited from someplace else or not, just that the actual ACL was correct.
For example, to perform a file ACL test without regard if it is "inherited" or "not inherited", use the phrase "not used" with the "acl_inheritance" keyword. Below is an example .audit file which performs a file ACL test without regard if the policy were inherited or no

# Detecting Compromised Windows Hosts
Ron Gula
December 19, 2006
3 Min Read
Tenable recently added a credentialed Windows check (Nessus ID #23910) to find systems that have been infected by certain viruses. The check considers the contents of the file:
```
SYSTEM32\Drivers\etc\HOSTS
```
and sees if it has been manipulated to prevent virus updates. A common virus technique (such as in MyDoom, Bagel and their variants) is to disable a computer's ability to update its anti-virus signatures once it has been compromised. Typical anti-virus software performs a DNS lookup to find the update server where new signatures are available.
By adding alternate IP addresses (usually 0.0.0.0) for common update sources such as Symantec, Sophos, Microsoft, Kaspersky and so on, a viru

Tenable has released 32 plugins for Nessus 3 which specifically test SCADA devices. These plugins were the result of a four month research contract between Tenable Network Security and Digital Bond. This blog entry details how to obtain the plugins, strategies for using them with Nessus and strategies for using them in concert with Tenable products such as the Security Center and Passive Vulnerability Scanner.
Availability and Compatibility
All Direct Feed and Security Center users will receive these plugins through a plugin update. The SCADA plugins are only available to Tenable Direct Feed or Security Center customers. Other compatibility notes to consider:

If you are performing credentialed patch audits with Nessus, you can also create an inventory of installed software on each of your UNIX and Windows hosts. This blog post will review how Nessus can perform these tasks and what you can do with the results.
Finding Software on UNIX and Windows Systems
For Windows servers, Nessus plugin #20811 will enumerate all of the installed software by considering the "Uninstall" values set in the registry. This technique won't detect a simple executable present on a system, but it will find just about any piece of software that uses an installer. This particular check uses registry calls because it is intended to be generic. Other checks that Nessus

# CVSS Scores in Nessus Plugins
George A. Theall
November 16, 2006
1 Min Read
For over a year now, Tenable has been including CVSS base scores in the plugins we write for Nessus as well as Passive
Vulnerability Scanner (PVS) to give our customers an objective way to
assess the risk of flaws those plugins test for. We've been
calculating these scores in-house during the course of investigating
vulnerabilities and how to test for them. Until recently, our efforts
have been largely independent of NIST's own work in this area.
Since early November, though, Tenable has been using the CVSS scores
that NIST calculates and includes in its National Vulnerability Database. We still calculate our own scores initially, as our plugins are
often released at the same time -- or eve

# Using Nessus 3 for OS X Configuration Auditing
Ron Gula
November 3, 2006

Nessus 3 users who have subscribed to the Direct Feed service can audit the configurations of many OSes, including OS X. This blog entry will show the basic configuration of an OS X device to allow auditing by Nessus 3.
Configuring Remote Auditing for OS X
The first step to auditing an OS X system with Nessus is to allow remote SSH access. To do this, as an administrator of the OS X system, under sharing, enable "Remote Login" as is shown below:
By default, your firewall settings should allow inbound SSH to the OS X system. If you've modified your firewall configuration to stop SSH or block certain IP addresses, this may effect your Nessus scanning.
Next you must create a user an

# Limiting the Ports Probed by Nessus Scans

A common question our support group receives from Direct Feed customers is how to limit Nessus probes to specific ports. This post will discuss the reasons Nessus sends packets to various ports and how scans can be configured to limit access to specific ports or ranges of ports.
Limiting The Port Scan
The first item someone should decide in an effort to minimize the ports touched by a Nessus scan is to enter in specific ports for scanning. Most Nessus clients have a default scan policy setting of "default". This causes the Nessus port scanner used to scan all TCP ports in the /etc/services file. Users can enter in more specific ranges and ports such as "21-80", "21,22,25,80" or "21-14

Security Center users and the Direct Feed subscribers have the ability to audit the host-based configuration of their UNIX and Windows servers. Tenable has produced several audit polices based on our own research, public guidance from CERT, NSA, NIST and the Center for Internet Security. For the Windows operating system, Tenable has also produced the Windows Nessus Policy Creator (WNPC). This entry will discuss the purpose and usage of the tool.
Many of Tenable's customers have told us that their provisioning, network management or change control processes require that "like" servers be configured the same way. For example, an organization might run twelve Exchange servers and twen

# Understanding the Nessus "Safe Checks" Option

Nessus has more than 11,000 plugins which can be used to audit networks with host based checks and network checks. There are also many different options that Nessus users can configure to optimize their scans. One of these options is to enable or disable "safe checks". The "safe checks" setting allows Nessus users to enable a set of plugins within Nessus' library of vulnerability checks which Tenable feels can have negative effects on the network, device or application being tested. This post will explain why disabling "safe checks" for testing pre-production equipment is a good idea, why enabling "safe checks" for production testing is recommended and why some network plugins for Ne

Tenable's research group recently added a Nessus 3 audit policy for Red Hat Linux. This allows Direct Feed users who are auditing missing security patches with SSH credentials to also ensure the system has been properly locked down.
The audit tests for several hundred different items such as the permissions of /var/log/messages and if any user accounts have poor permissions in their home directories. Audit files for Solaris, security recommendations from CERT and generic UNIX checks are also available in addition to many checks for a variety of Windows policies.

For first-time (and even veteran) Nessus users, Tenable support often gets questions about how to access the security of a host that is behind a firewall. Regardless if you are running Nessus for the first time, or deploying distributed Nessus scanners managed by Tenable.sc or Tenable.io, knowing how to scan systems protected by firewalls is vital. This post will discuss several issues with scanning hosts behind firewalls and strategies Nessus users can use to overcome this.

These PVS rules were very popular with our customers in the power and manufacturing industries which led us to put together the paper "Protecting Critical Infrastructures - SCADA Network Security Monitoring". This paper outlined some of the real and perceived risks to performing security, and showed how following the Department of Energy's 21 steps for securing SCADA networks can be accomplished wit

Today, Tenable released two new plugins for Nessus 3 that can audit the configuration of a remote UNIX or Windows system and report "compliant" or "not compliant" with a set of user-defined security policy configuration settings. We've also written policies based off of the publicly available hardening and best practice guides from the NSA, NIST, CERT and the Center for Internet Security. These plugins are available to any Nessus Direct Feed customer or Security Center user.
Along with the new plugins and audit policies, we also have released two tools that allow users to quickly build their own polices for scanning Windows hosts. The i2a.exe (inf to audit) Windows executable allows users to c

The Tenable Research Team has made available an pre-compiled NASL script (an .nbin file) which can be used from any Nessus 3 installation to interact with a remote windows host on top of port 139 or 445. This can be used to:
- Navigate thru the remote SMB shares and download files or obtain their version number
- Read/Enumerate the remote SMB registry
- Query/Start/Stop/Pause remote services
- Query information about the remote users / groups
- Obtain an interactive shell (cmd.exe) on the remote host
The .nbin file requires Nessus 3 on UNIX or Windows. For more information and to download the tool, please visit here. The link also includes a quick flash demo and documentation on how to install use this pl

# Enhanced VMWare Detection
Ron Gula
July 19, 2006

Plugin #20094 attempts to guess if the target host is indeed a system run under VMWare. It does this by looking at the Ethernet address and checking to see if it is one allocated to VMWare "hardware". To do this, the plugin looks in the knowledge base of the scan to obtain the Ethernet address.
Originally, the MAC address was either obtained by a local ping (plugin #10180) or from scanning a Windows host. Tenable recently added a change to the SSH login process such that the local MAC addresses are also populated into the knowledge base. This means that a non-Windows VMWare hosts not on the local network will now be detected as a VMware host.

# Detecting when Credentials Fail

If you are using Nessus to perform credentialed audits of UNIX or Windows systems, analyzing the results to determine if you had the correct passwords and SSH keys can be difficult. Nessus users can now easily detect if their credentials are not working. Tenable has added Nessus plugin #21745. This plugin detects if either SSH or Windows credentials didn't allow the scan to log into the remote host.

NoiseLetter March 2026
Events, events… and yes, even more events. 🌍 GreyNoise has been on the move. March kept us busy with stops at eCrimes in London and SecIT in Hanover—but we’re just getting started. Over the next few months, we’ll be hitting the road for CrowdStrike CrowdTours across eight cities, heading to Glasgow to speak and sponsor CyberUK, and making our way to Tampa for H-ISAC. If you’ll be at any of these (or nearby), we’d love to connect.
And while we’ve been racking up miles, we haven’t slowed down on the research front. We’ve just released some exciting new findings—with even more coming in the next few weeks—so keep an eye out.
Thanks, as always, for being part of the GreyNoise community.
