A sensor enters RFM when its installed on a host that has an incompatible kernel on a supported Linux distro. So tools that rely on DNS (for example BloodHound) will not work out-of-box. The user is then running Process Hacker with elevated privileges, by accepting UAC prompts, to load a kernel driver (KProcessHacker) on the Windows system. In the case of the SOC team we were dealing with, their analysts managed to build upon anomaly mapping to the point where they could detect pretty much any command-line usage that was not absolutely trivial (and were talking about an organization with hundreds of thousands of machines to monitor). Yes, CrowdStrike and Defender can co-exist on the same endpoint. How ever, we have no alerts or any event log entries.
