What it detects

This rule detects a Node.js process spawning tasklist with CSV no-header output, the process-enumeration recon used by OmniStealer to identify security tooling. The malware parsed the CSV process list to hash and match process names before attempting to terminate defenders. A node.exe parent running tasklist in this scripted format indicates automated host reconnaissance by the RAT.
