What it detects

This rule detects Discord or Telegram desktop clients spawning command shells and scripting interpreters as child processes. Adversaries abuse instant messaging platforms for command and control, using the legitimate client as a launch point for follow-on execution. A messaging application spawning cmd, PowerShell, or scripting hosts is anomalous and indicates malicious tooling masquerading as chat software.
