What it detects

This rule detects a Run key persistence value that launches the Deno runtime through a headless conhost wrapper. TAG-150 uses this technique across its DinDoor, DenoRAT, and NightshadeC2 tooling to silently reload JavaScript backdoors at logon. The headless conhost prefix suppresses the console window while maintaining autostart command and control.
