What it detects

This rule flags Windows process executions whose command line includes specific parameter patterns associated with ADCSPwn. The behavior matters because ADCSPwn is used to interact with AD CS endpoints and can be leveraged as part of privilege escalation in active directory environments. Telemetry relies on process creation events with access to full command-line arguments.
