What it detects

This rule detects execution of service-sounding binaries dropped by the Contagious Interview toolkit from a user profile directory rather than a system location. The North Korean operators name their implants to imitate host, print and DHCP services to blend in. Running such a binary out of a user path is a strong masquerading indicator of the second-stage RAT.
