- ·Ivanti's patch (RPM 12.x.0.x or RPM 12.x.1.x, version-specific not vulnerability-specific) requires no downtime; organizations should also review appliances for signs of pre-patch exploitation, as dormant backdoors may persist after patching. ↗

CVE-2026-6973 [CRITICAL] CISA gives feds four days to patch Ivanti flaw exploited as zero-day
## CISA gives feds four days to patch Ivanti flaw exploited as zero-day
## Sergiu Gatlan
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has given U.S. federal agencies four days to secure their networks against a high-severity vulnerability in Ivanti Endpoint Manager Mobile (EPMM) that has been exploited in zero-day attacks.
Tracked as CVE-2026-6973, this security flaw allows attackers with administrative privileges to execute arbitrary code remotely on systems running EPMM 12.8.0.0 and earlier.
In a Thursday security advisory , Ivanti told customers they can secure their appliances by installing Ivanti EPMM 12.6.1.1, 12.7.0.1, and 12.8.0.1, and advised them to review accounts with Admin rights and rotate those credentials where necessary.

## Sergiu Gatlan
CISA has given U.S. government agencies four days to secure their systems against a critical-severity vulnerability in Ivanti Endpoint Manager Mobile (EPMM) that has been exploited in attacks since January.
Tracked as CVE-2026-1340 , this critical-severity code injection flaw enables threat actors without privileges to gain remote code execution on Internet-exposed and unpatched EPMM appliances.
Ivanti flagged this and a second security bug (CVE-2026-1281) as abused in zero-day attacks when it released security updates on January 29 to patch both vulnerabilities and "strongly" encouraged all customers to update their systems to block ongoing exploitation.

## Bill Toulas
Update: The article initially listed the wrong CVEs. This has now been corrected to list the CVEs: CVE-2026-1286 and CVE-2026-1340
Threat intelligence observations show that a single threat actor is responsible for most of the active exploitation of two critical vulnerabilities in Ivanti Endpoint Manager Mobile (EPMM), tracked as CVE-2026-1281 and CVE-2026-1340.
The security issues have been flagged as actively exploited in zero-day attacks in Ivanti's security advisory, where the company also announced hotfixes.
Both flaws received a critical severity rating and allow an attacker to inject code without authentication, leading to remote code execution (RCE) on vulnerable systems.

The European Commission is investigating a breach after finding evidence that its mobile device management platform was hacked. The Commission said on Friday that it detected traces of a cyberattack targeting infrastructure that manages its staff's mobile devices.
While the attackers may have accessed some staff members' personal information, including names and phone numbers, the Commission has not yet found evidence that their mobile devices were compromised.
"On 30 January, the European Commission's central infrastructure managing mobile devices identified traces of a cyber-attack, which may have resulted in access to staff names and mobile numbers of some of its staff members," it said .

## Executive Summary
This article introduces a simple and straightforward technique for jailbreaking that we call Deceptive Delight. Deceptive Delight is a multi-turn technique that engages large language models (LLM) in an interactive conversation, gradually bypassing their safety guardrails and eliciting them to generate unsafe or harmful content.
We tested this simple yet effective method in 8,000 cases across eight models. We found that it achieves an average attack success rate of 65% within just three interaction turns with the target model.

Every now and then, a new domain name system (DNS) vulnerability that puts billions of devices around the world at risk is discovered. DNS vulnerabilities are usually critical. Just imagine that you browse to your bank account website, but instead of returning the IP address of your bank website, your DNS resolver gives you the address of an attacker’s website. That website looks exactly the same as the bank’s website. Not only that, but even if you take a look at the URL bar, you won’t see anything wrong because your browser actually thinks this is the websit

The problem caused containers that use images which are supposed to run with a non root user to run as root, on the second time they are used or upon restart of the container.
Before elaborating on this particular security issue, let’s first clarify why running a program as root in a container is even a concern at all.

## Executive Summary
A vulnerability in the USBCreator D-Bus interface allows an attacker with access to a user in the sudoer group to bypass the password security policy imposed by the sudo program. The vulnerability allows an attacker to overwrite arbitrary files with arbitrary content, as root - without supplying a password. This trivially leads to elevated privileges, for instance, by overwriting the shadow file and setting a password for root. The issue was resolved in June when Ubuntu patched the relevant packages in response to a vulnerability disclosur

In December 2018, a hacker who goes by the alias ‘SandboxEscaper’ publicly disclosed a zero-day vulnerability in the Windows Error Reporting (WER) component. Digging deeper into her submission, I discovered another zero-day vulnerability, which could be abused to elevate system privileges. According to the Microsoft advisory, attackers exploited this bug as a zero-day in the wild until the patch was released in May 2019.
So how did this bug work exactly?

We’ve discovered a new family of iOS malware that successfully infected non-jailbroken devices we’ve named “AceDeceiver”.
What makes AceDeceiver different from previous iOS malware is that instead of abusing enterprise certificates as some iOS malware has over the past two years, AceDeceiver manages to install itself without any enterprise certificate at all. It does so by exploiting design flaws in Apple’s DRM mechanism, and even as Apple has removed AceDeceiver from App Store, it may still spread thanks to a novel at

Continuing a recent trend in which Internet Explorer vulnerabilities are exploited using Flash, samples of an SWF purportedly used in conjunction with CVE-2014-6332 have appeared in several places. The most famous examples of this trend are the exploits for CVE-2014-0322 and CVE-2014-1776 .
We have yet to encounter the SWF sample with its original exploit attached, but by looking at the SWF, it is clear that it is constructed to function with several forms of memory corruption, making the vulnerability itself less interesting. That is a great example of why our Advanced Endpoint Protection approach, which focuses on the

I am sure I am not the only one who has answered a question or two from his mother-in-law about how the Internet is melting down based on what she’s been reading in the press.

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.
