What it detects

This rule detects a Run key value referencing client32.exe staged under ProgramData. ClickFix operators deploy the NetSupport remote access tool as client32.exe and persist it through the CurrentVersion Run key. A remote control agent auto-started from ProgramData is a common abuse of otherwise legitimate NetSupport Manager software.
