What it detects

This rule detects DNS queries to dynamic DNS and tunneling provider domains frequently abused by commodity remote access trojans such as XWorm AsyncRAT DCRat and njRAT for command and control. These providers let adversaries map attacker infrastructure to disposable hostnames and tunnel traffic past network controls. Detecting lookups to these domains surfaces potential RAT beaconing that warrants investigation.
