    Attacker's goals: An attacker can abuse the Distributed File System Namespace Management protocol to coerce an authentication from a DC. This authentication can later be used for obtaining a DC certificate for DCSync.
    Investigative actions: Check for a suspicious process on the initiator. Check if the source host is a vulnerability scanner. Look for unusual AD CS certificate requests. Check for possible DCSync alerts.
