This week has already been rough for cybersecurity. Critical PHP and GitLab RCE flaws, serious Linux security bugs , compromised eMudhra certificates , a Node.js RCE flaw , a hacked LiteLLM release, and hundreds of hijacked Tor relays . That's a lot to deal with in just a few days. And the week isn't even over yet. But those big headlines are only half the story. Stolen passwords, exposed databases, broken login checks, and trusted tools being turned against their users are causing trouble too. Some attacks are clever. Others work because someone left a simple security gap open. This ThreatsDay, we're digging into the stories that didn't make as much noise but still deserve attention. Some are strange, some are serious, and a few might surprise you. Here's everything else you shouldn't miss this week. The threats change every week. Subscribe, and we’ll alert you when each new ThreatsDay Bulletin is out.

The safety check that is supposed to stop an AI coding agent from running a dangerous command can be walked straight past using a shell trick that has been public for decades. New research from  Adversa AI , which is named the bypass GuardFall , found it works against ten of the eleven popular open-source coding and computer-use agents the firm tested. Only one, "Continue," was built to defend against it. Why does it matter? These agents run shell commands with your full account access. Point one at a booby-trapped repository or software package, and a hidden instruction can quietly run a command that wipes files or steals the secrets your account can reach, from SSH keys and cloud credentials to anything sitting in your home folder. How does it get past the guard? Most of these agents try to stay safe by checking each command against a blocklist of dangerous patterns before running it. The flaw is that they check the command as plain text, while bash rewrites that t...
