What it detects

This rule detects PowerShell executing a script named Untitled1.ps1 from the ProgramData directory, matching the vibe-coded Active Directory enumeration tool analyzed by Huntress. The default editor script name dropped into a world-writable path is used to run domain reconnaissance. Execution of this named script from ProgramData indicates hands-on-keyboard enumeration.
