What it detects

This rule detects the NetSupport Manager client (client32.exe) running from the ProgramData directory, the remote access tool abused as a RAT in campaigns delivering malware through MSIX installers per Red Canary. Legitimate NetSupport deployments live under Program Files, so execution from ProgramData indicates an attacker-installed remote access foothold.
