What it detects

This rule detects a Run key value named Deno_AutoRun created for persistence by the DenoGate backdoor delivered through Microsoft Teams IT impersonation. The value silently relaunches the Deno runtime under a headless conhost wrapper at logon. This fixed autostart name reestablishes the backdoor and its WebSocket command and control after reboot.
