So how did McAfee ENS 10.5 would fare to this attack?


In the test, we obtained one sample to test it against a Windows 7 that has ENS 10.5 installed

The AV were turned off as to ensure only DAC and RP is providing the protection to the endpoint.

As a result, the malware sample was successfully prevented by the DAC rules (which is shown below).

McAfee ENS Analyzer content creation date for both of the DAC Rules were created on Aug 2016, whereas the ransomware was made known to public on 23 Nov . Taking those two dates, McAfee endpoint solution provided pre-emptive protection of more than 12 months before this ransomware was publicly known
