What it detects

This rule flags process creation where ConfigSecurityPolicy.EXE is executed with HTTP or FTP URLs present in the command line, indicating potential arbitrary file upload or download behavior. Attackers may abuse this signed Windows Defender component to move files over the network as part of data exfiltration or staging. The detection relies on Windows process creation telemetry including Image/OriginalFileName and command-line contents.
