Description
A possible abuse of Distributed File System Namespace Management (DFSNM).
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.
