What it detects

This rule flags execution of PowerShell modules whose ContextInfo contains filenames associated with known offensive PowerShell scripts and reconnaissance/exploitation tooling. Attackers often rely on publicly available PowerShell modules to quickly stage credential theft, persistence, privilege escalation, and data collection with minimal custom code. It relies on Windows PowerShell module telemetry providing ContextInfo that includes the script or module filename substrings listed by the rule.
