## ⚡ Weekly Recap: $387M Crypto Hack, Citrix Exploits, AI Agents Go Off-Script, and More Threats
A domain used as harmless placeholder text showed up in roughly 1,700 repositories. Then somebody registered it and started serving malicious lures. That is the kind of week this was: forgotten assumptions turning into live attack surface.

Here’s the full recap of what mattered this week.
