Exploit Prevention Rule 6182 - CVE_2020_1472 Zerologon attack

[cybercop]

I've placed Exploit Prevention rule 6182 - CVE_2020_1472 Zerologon attack, into report mode and immediately I'm seeing hits against "C:\WINDOWS\system32\drivers\MfeEpNfcp.sys" and "C:\WINDOWS\SYSTEM32\SPOOLSV.EXE". I'm fairly sure these are false positives but do I white list them in the Exploit Prevent exclusions, which excludes them from all rules?

Hi @cybercop 

Thanks for reaching out to community. 

If these are false detections, I request you to open an SR with point product as MALWARE and description as "Exploit Prevention False positive" and we can escalate to our labs and get this addressed. 

This needs to be addressed by our Content Team and white list accordingly.

Hi @Thyssenkrupp 

Thank you for posting in community forum. Could you please provide more details on when and how you started seeing these events in your environment?

I would suggest to raise a Service Request with McAfee Support and provide details of the event received along with logs to check this event further.

Kind Regards,
