Datashield recommends patching any Microsoft Windows domain controllers due to the recently released vulnerability, CVE-2020-1472, and subsequent release of publicly available proof of concepts (POC’s). An unauthenticated attacker with access to the network and a route to a domain controller, will allow attackers to compromise it and obtain domain admin privileges in the network. There is no current mitigation besides patching the affected domain controllers.

Installing the August 2020 Microsoft patch on all domain controllers will prevent the exploit. Datashield is also currently creating rules and alerts to detect this exploit and will be deploying detections.
