What it detects

This rule detects a PowerShell binary copied to wt.exe under ProgramData and executed with a hidden window and execution policy bypass, matching the Axios NPM supply chain incident where a post-install hook drops a RAT. Renaming powershell.exe to wt.exe masquerades the interpreter as Windows Terminal to evade name-based detection. Execution of a masqueraded interpreter from ProgramData with bypass flags is a strong compromise indicator.
