Stay Ahead With Linux Security News

Root access on a Linux system rarely arrives through a zero-day. . Honestly, it usually doesn't even arrive through something you'd consider clever. More often — and this shows up in post-incident report after post-incident report — an attacker gets a low-privilege foothold through a misconfigured web app or a reused credential, and then just looks around. What they find is a sudoers entry that's been sitting untouched since the last sysadmin handed off the server. Or a SUID binary a...

Every Linux developer who works with Go has run the same workflow a thousand times. You find a library that solves your problem, you see a decent star count on GitHub, and you run go get. It is frictionless and efficient. Lately, however, it is becoming one of the most effective ways for an attacker to get code running on your build servers. The recent "Operation Muck and Load" campaign is a perfect example of why this workflow is risky. Researchers uncovered over 200 GitHub repositories...

AI coding assistants have become a staple in many Linux developers' daily workflows. Whether you're generating boilerplate, refactoring code, or updating configuration files, it's easy to assume these tools stay safely inside your project directory. . Researchers recently pulled the curtain back on a threat they’ve dubbed " GhostApproval ." It’s a direct hit to the way we use tools like Cursor, Amazon Q, and Claude Code. They found these assistants have a dangerous blind spot: they can be...

Linux runs a huge portion of today's infrastructure because it gives administrators an unusual amount of control over the system. That control extends to networking, where almost every aspect of packet flow, routing, filtering, and interface behavior can be customized. The trade-off is that very little of that hardening happens automatically. A fresh installation is usually built to communicate, not to isolate. . As environments grow, servers start exchanging data with monitoring platforms,...

We often view OpenSSH security updates through the lens of standard patch management. When a new CVE hits, we scramble to update, check our versions, and return to business as usual. But recent vulnerabilities tied to distribution-added OpenSSH GSSAPI patches are a reminder that the danger doesn't always lie in the core code; it often resides in the "convenience" features we layer on top. . These recent issues shouldn't just trigger an apt upgrade or dnf update; they should trigger a...
