Learn how critical Linux kernel flaws in CopyFail, Dirty Frag, and Fragnesia let unprivileged users escalate to root access. See what security teams can do to remediate.
When a critical Linux kernel privilege escalation was publicly disclosed, Cloudflare's security and engineering teams detected, investigated, and mitigated the threat across our global fleet, confirming zero customer impact and no malicious exploitation.
On 29 April 2026, a high local privilege escalation vulnerability in the Linux kernel, tracked as CVE-2026-31431 and named "Copy Fail", was publicly disclosed. The vulnerability affects every mainstream Linux distributions shipping a kernel built since 2017. A public proof-of-concept exploit has been released. As of the date of this advisory, no distribution has shipped a fixed kernel package. The mainline fix was committed on 1 April 2026, but vendor updates are still pending across all major …
A developer used OpenAI’s Codex to handle suspicious activity, leading to unexpected outcomes found by Huntress SOC analysts during an investigation.
A Linux user recently tried to respond to potentially malicious behavior on their machine using OpenAI’s Codex coding agent, before installing the Huntress agent. What ensued shows the unexpected impacts of this AI use case on DFIR investigations.
Huntress uncovers a tax-themed malvertising campaign using Google Ads, dual cloaking, rogue ScreenConnect, and an undocumented Huawei driver to kill AV/EDR.
Learn about the narrowing threat gap, the rise of cross-platform attacks (like WSL abuse), and the specific ransomware and nation-state actors targeting Linux endpoints in 2026.
Huntress researchers weigh in on the challenge of getting feature parity across Windows, macOS, and Linux. And learn how unique security models and platform maturity shape the way products are built.
Huntress is seeing threat actors exploit React2Shell (CVE-2025-55182) to deploy a Linux backdoor, a reverse proxy tunnel, and a Go-based post-exploitation implant.
Posted by Liz Prucka, Hamzeh Zawawy, Rishika Hooda, Android Security and Privacy Team Last year, Google's Android Red Team partnered with Arm to conduct an in-depth security analysis of the Mali GPU, a component used in billions of Android devices worldwide. This collaboration was a significant step in proactively identifying and fixing vulnerabilities in the GPU software and firmware stack. While finding and fixing individual bugs is crucial, and progress continues on eliminating them entirely…
Posted by Jeff Vander Stoep, Android Last year, we wrote about why a memory safety strategy that focuses on vulnerability prevention in new code quickly yields durable and compounding gains. This year we look at how this approach isn’t just fixing things, but helping us move faster. The 2025 data continues to validate the approach, with memory safety vulnerabilities falling below 20% of total vulnerabilities for the first time. Updated data for 2025. This data covers first-party and third-party…
Discover how attackers could manipulate the Linux /proc filesystem to hide malicious processes and distort forensic timelines. This technical deep dive highlights examples of command-line substitution and start time corruption, and offers detection and defense strategies for incident responders and security analysts.
One year from now, with the release of Chrome 154 in October 2026, we will change the default settings of Chrome to enable “Always Use Secure Connections”. This means Chrome will ask for the user's permission before the first access to any public site without HTTPS. The “Always Use Secure Connections” setting warns users before accessing a site without HTTPS Chrome Security's mission is to make it safe to click on links. Part of being safe means ensuring that when a user types a URL or clicks o…

A critical vulnerability in AZNFS-mount utility, preinstalled on Azure HPC/AI images, allowed unprivileged users to escalate privileges to root on Linux machines. The flaw existed in versions up to 2.0.10 and involved a SUID binary. Azure classified it as low severity but fixed it in version 2.0.11.

A vulnerability in Azure Function Apps allowed extraction of Managed Identity credentials from the encrypted startup context of Linux containers. This gave attackers with container access the ability to persist as the Managed Identity, breaking the intended security model. Microsoft has since patched the issue by encrypting the sensitive payload.
