Gryxa: The AI-Built Toolkit That Watches How You Remove It
ReliaQuest researchers identified Gryxa, a toolkit deployed across 324 hosts by a financially motivated actor who leveraged a commercial artificial intelligence (AI) coding agent to build major components. The toolkit abuses legitimate remote monitoring and management (RMM) software for persistent access, steals browser-stored credentials, and noticeably collects forensic evidence of how defenders remove it. When defenses cut the actor's relay connection, Gryxa escalates by disabling endpoint protection within minutes.
Why it matters: Organizations running RMM software face persistent backdoor access through Gryxa unless all seven scheduled tasks, the Windows Management Instrumentation (WMI) event subscription, and the off-path file cache are removed simultaneously; partial cleanup triggers automatic antivirus (AV) disablement. Practitioners must block the actor's infrastructure first, then remove all persistence in one pass, and assume any responding account and tooling details are now visible to the threat actor.
