Open up a browser and navigate to the Sensor Downloads section of the Crowdstrike management portal or you could alternatively click on the Sensor Downloads item on the Falcon dashboard as shown below. 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). There are no other words - It worked beautifully: Using our new deployed VM, we were able to run arbitrary scripts and scans against the network (DNS included), and stay completely invisible to CrowdStrike and the blue-team. A similar elevation trick has been used by DarkSide and REvil ransomware families in the past. For an up-to-date list of kernel support, including kernel support added through channel files, see Supported kernels. Crowdstrike is a set of advanced EDR (endpoint detection and response) applications and techniques to provide an industry-leading NGAV (next generation anti-virus) offering machine learning to ensure breaches are stopped before they occur, Crowdstrike monitors processes running on OS by hooking, so if we run any malicious process on a machine it will monitor and log it, this all happens at in kernel level.
