38 detections

This rule detects DNS queries that match a specific pattern indicative of C2 fallback domain rotation. The pattern looks for domains consisting of 8 to 12 alphanumeric characters followed by a top-level domain (TLD) from a list including .top, .xyz, .club, .icu, or .pw. This behavior is often associated with malware using domain generation algorithms (DGAs) or similar techniques for command and control communication, specifically as a fallback mechanism when primary C2 channels are disrupted.

NXDomain records in prior 10-day baseline period).
