What it detects

This rule detects execution of the SimpleHelp or Advanced Monitoring Agent remote management tools, which MuddyWater deployed in the eN-Able spear-phishing operation to gain hands-on-keyboard control of victim hosts. Adversaries abuse legitimate RMM software for stealthy remote access that survives endpoint controls, so unexpected installs warrant review.
