Stay Ahead With Linux Security News

Spin up a fresh Linux VPS with default settings and check /var/log/auth.log ninety seconds later. There will already be failed login attempts — not dozens, hundreds, sometimes before the deployment script has even finished running. . Automated bots scan the entire IPv4 address space non-stop, and port 22 with password authentication open is exactly what they're looking for. Most cloud providers have seen enough of this that a new instance gets its first probe within a minute of going live....

There was a time when Linux meant server rooms and hobbyist forums. These days it's on regular laptops, and a big part of that is people getting fed up with commercial operating systems scraping their data, shipping telemetry nobody asked for, and boxing them into hardware ecosystems they can't opt out of. . None of that makes Linux immune to trouble though. Yes, it dodges most of the mainstream malware that everyone else deals with. But the software running on top, and honestly the person...

There's a gap between what Linux systems log by default and what you actually need to detect a compromise. Most environments have logging active, which creates a sense of coverage that doesn't hold up under investigation. . When you start pulling logs after an incident, what you find is fragmented activity — a login here, a process there, but no clear narrative of how access was gained, what was executed, or how far the attacker moved. You piece together a timeline rather than reading one....

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...
