How Huntress Uses Managed SIEM to Detect Threats Faster

blogs_huntress·2026-05-21

CVE-2025-55182 How Huntress Uses Managed SIEM to Detect Threats Faster At Huntress, customer protection shapes how we build and operate. Security isn’t a separate consideration for one team or one phase of development. It runs through the entire process, from product design to threat operations. That focus continues after release. A new feature is only useful if it helps defenders investigate faster, understand incidents more clearly, or catch activity they'd have otherwise missed. That’s why close collaboration between Product and frontline teams matters so much. You can already find plenty of detailed examples in our blogs from Dray Agha , Tactical Response, and the DE&TH (Detection Engineering & Threat Hunting) team. But what really drives those stories—and the successes behind them—is how Huntress teams actually use Managed SIEM . ## A tight feedback l

Google: Cloud attacks exploit flaws more than weak credentials

blogs_bleepingcomputer·2026-03-09·CVSS 9.8

CVE-2025-55182 [CRITICAL] Google: Cloud attacks exploit flaws more than weak credentials ## Google: Cloud attacks exploit flaws more than weak credentials ## Bill Toulas The most frequent vulnerability type exploited in attacks is remote code execution (RCE), the highlights being React2Shell (CVE-2025-55182) and the XWiki flaw tracked as CVE-2025-24893, leveraged in RondoDox botnet attacks . Google believes this shift in focus was likely due to increased security measures for accounts and credentials. “We assess that this change in behavior from threat actors is potentially due to Google's secure-by-default strategy and enhanced credential protections successfully closing traditional, more easily exploitable paths, raising the barrier to entry for threat actors,” Google says . The exploitation window has collapsed from weeks to a few days, as Google observed cryptominers

From React to Remote Code - Protecting Against the Critical React2Shell RCE Exposure

blogs_sentinelone·2025-12-05·CVSS 10.0

[CRITICAL] From React to Remote Code - Protecting Against the Critical React2Shell RCE Exposure A critical remote code execution (RCE) vulnerability, dubbed ‘React2Shell’, affecting React Server Components (RSC) and `Next.js`, is allowing unauthenticated attackers to perform server-side code attacks via malicious HTTP requests. Discovered by Lachlan Davidson, the flaw stems from insecure deserialization in the RSC ‘Flight’ protocol and impacts packages including react-server-dom-webpack, react-server-dom-parcel, and react-server-dom-turbopack. Exploitation is highly reliable, even in default deployments, and a single request can compromise the full `Node.js` process. The flaw is being tracked as CVE-2025-55182. Originally tagged as a CVE for `Next.js`, NIST subsequently rejected CVE-2025-66478, as it is a duplicate of CVE-2025-55182. This blog post includes the critical, immediate

CVE-2025-55182 [CRITICAL] Critical React2Shell flaw actively exploited in China-linked attacks ## Critical React2Shell flaw actively exploited in China-linked attacks ## Bill Toulas Multiple China-linked threat actors began exploiting the React2Shell vulnerability (CVE-2025-55182) affecting React and Next.js just hours after the max-severity issue was disclosed. React2Shell is an insecure deserialization vulnerability in the React Server Components (RSC) 'Flight' protocol. Exploiting it does not require authentication and allows remote execution of JavaScript code in the server's context. For the Next.js framework, there is the identifier CVE-2025-66478, but the tracking number was rejected in the National Vulnerability Database's CVE list as a duplicate of CVE-2025-55182.

The underlying issue is data serialization/deserialization, which evoked thoughts about a blog I wrote in 2016 , addressing the same issue (at the time, the topic was CVE-2015-4852 , a serialization flaw in Java objects that affected Oracle and Apache products). ## 2 Risk Takeaways The exploit pattern repeats because serialization is a straightforward method for transferring data, and developers typically use what works.

blogs_securelist·2025-02-21

New wave of targeted attacks of the Angry Likho APT on Russian organizations Table of Contents - Technical details - New activity - Victims - Attribution - Conclusion - Indicators of compromise Authors - Kaspersky Angry Likho (referred to as Sticky Werewolf by some vendors) is an APT group we’ve been monitoring since 2023. It bears a strong resemblance to Awaken Likho, which we’ve analyzed before, so we classified it within the Likho malicious activity cluster. However, Angry Likho’s attacks tend to be targeted, with a more compact infrastructure, a limited range of implants, and a focus on employees of large organizations, including government agencies and their contractors. Given that the bait files are written in fluent Russian, we infer that the attackers are likely native Russian speakers. We’ve identified hundreds of victims of this attack in Russia, sev

During this very in-depth 3-day assessment, our and other vendors technologies were tested against emulated attack techniques of the APT29 threat group. The MITRE ATT&CK Evaluation is a unique exercise in many ways. One of its distinguishing features is the absence of any scores or ratings to enable the direct comparison of participants (as happens in anti-malware tests). The result of the Evaluation is a complex table of assessments of all detections that a given security solution has produced, for different stages of the attacks of a specific adversary.

The return of Fantomas, or how we deciphered Cryakl Authors - Kaspersky In early February this year, Belgian police seized the C&C servers of the infamous Cryakl cryptor. Soon afterwards, they handed over the private keys to our experts, who used them to update the free RakhniDecryptor tool for recovering files encrypted by the malware. The ransomware, which for years had raged across Russia (and elsewhere through partners), was finally stopped. For Kaspersky Lab, this victory was the culmination of more than three years of monitoring Cryakl and studying its various modifications — a major effort that eventually defeated the cybercriminals. This story clearly illustrates how cooperation can, in the end, get the better of any crooked scheme. This spring marked the fourth anniversary of the malware’s first attacks.

Financial Cyberthreats in 2017

blogs_securelist·2018-02-28

Financial Cyberthreats in 2017 Authors - Kaspersky In 2017, we saw a number of changes to the world of financial threats and new actors emerging. As we have previously noted, fraud attacks in financial services have become increasingly account-centric. User data is a key enabler for large-scale fraud attacks, and frequent data breaches – among other successful attack types – have provided cybercriminals with valuable sources of personal information to use in account takeovers or false identity attacks. These account-centric attacks can result in many other losses, including those of further customer data and trust, so mitigation is as important as ever for both businesses and financial services customers. Attacks on ATMs continued to rise in 2017, attracting the attention of many cybercriminals, with attackers target

Given that Kaspersky Lab has been at the forefront of fighting cyberespionage and cybercriminal activities on the Internet for over 20 years now, these allegations were treated very seriously. To assist any independent investigators and all the people who have been asking us questions whether those allegations were true, we decided to conduct an internal investigation to attempt to answer a few questions we had related to the article and some others that followed it: 1.

For example, we found open access to around 1,500 devices used to process patient images. In addition, we found that a significant amount of connected medical software and web applications contains vulnerabilities for which published exploits exist. This risk is heightened because cyber-villains increasingly understand the value of health information, its ready availability, and the willingness of medical facilities to pay to get it back. ## What can we expect in 2018?

I knew that some form of port scan was needed. Maybe I could start with a ping sweep of some IP range, or maybe something more comprehensive. But my manager also added some nuance to the project. I had to put myself in the shoes of a Tenable customer, and my objective was to present a plan to discover machines and to identify the Cyber Exposure risk on the lab network using Tenable.io. The first step was to define the network subnets, and then I had to scan the networ

No Free Pass for ExPetr Authors - Kaspersky Recently, there have been discussions around the topic that if our product is installed, ExPetr malware won’t write the special malicious code which encrypts the MFT to MBR. Some have even speculated that some kind of conspiracy might be ongoing. Others have pointed out it’s plain and simple nonsense. As usual, Vesselin Bontchev, a legend in IT security, who’s become famous for usually getting things right, said it best: So, what is going on here? As a wise man once said, “the code doesn’t lie,” so let’s analyze the ExPetr MBR disk infection/wiping code in details. In a nutshell, the malware does these actions: 1. Checks administrator privileges 2. Enumerates running processes 3. Depending on the processes found, initialize a special runtime config 4. Depending on

CVE-2025-55182 [CRITICAL] The Bug That Won't Die: 10 Years of the Same Mistake # The Bug That Won't Die: # 10 Years of the Same Mistake ## A decade of deserialization vulnerabilities (and why we keep making them) CVE-2025-55182 Intelligence Card c/o Recorded Future There are now multiple publicly available exploit scripts (I forked one on GitHub here) for the React and Next.js vulnerabilities (CVE-2025-55182 and CVE-2025-66478). The underlying issue is data serialization/deserialization, which evoked thoughts about a blog I wrote in 2016, addressing the same issue (at the time, the topic was CVE-2015-4852, a serialization flaw in Java objects that affected Oracle and Apache products). Timeline illustrating the deserialization vulnerability impacts of 40+ critical CVEs across 6 ecosystems, over the course of 10 years. ## 2 Risk Takeaways - The exploit pattern

[CRITICAL] Tradecraft Tuesday Recap: React2Shell, ClickFix, and the Rise of AI Scams | Huntress Every security professional knows the drill. You go home for the holidays and, without volunteering, you become the family’s help desk, incident responder, and fraud advisor. Somewhere between dinner and dessert, someone will ask why their phone is acting strange, whether that unpaid traffic ticket warning is real, or what to do about a pop-up that won’t go away. This month’s Tradecraft Tuesday leaned into that role with Huntress Chief Information Security Officer (CISO) Chris Henderson and Director of Security and IT Brian Milbier giving everyone a plainspoken tour of the threats most likely to hit friends and relatives, and the small, practical steps that actually make a difference. ## Active ‘React2Shell’ exploitation The session started with a reminder that “consumer” and “enterpris
