description: This rule flags Windows file creation events where the target filename matches a large set of known offensive PowerShell script names or PowerShell modules. Attackers commonly drop these scripts to enable exploitation, credential theft, persistence, and other post-compromise actions under PowerShell. The detection relies on file event telemetry that captures the created file path or name, including suffix and substring matches for the script and module filenames.
