What it detects

This rule detects execution of the NetSupport Manager remote-control client32.exe, the remote access tool dropped as the final payload of the GitHub-hosted info stealer chain in this malvertising campaign. Adversaries repurpose the legitimate NetSupport client as a covert RAT for hands-on-keyboard control, so client32.exe running in an environment without a sanctioned NetSupport deployment indicates remote-access compromise.
