What it detects

This rule detects the NetSupport Manager remote control client client32.exe launching from a user AppData or Temp directory instead of a standard installation path. The Stan Ghouls intrusions weaponized NetSupport RAT by dropping client32.exe alongside PCICHEK.DLL into user-writable folders as reported by Kaspersky. Running this legitimate remote access tool from the wrong location indicates unauthorized remote control rather than sanctioned IT usage.
