description: This rule flags process creation events where the command line contains the provisioning commands registry path 'SOFTWARE\Microsoft\Provisioning\Commands\'. Abuse of this location can enable indirect command execution through Provlaunch.exe, helping attackers run additional payloads while blending into legitimate provisioning-related activity. It relies on Windows process creation telemetry with access to the full command line string.
