What it detects

This rule flags DNS traffic where endpoints attempt to resolve specific domains identified as command-and-control infrastructure tied to the axios/plain-crypto-js npm supply chain compromise. Attackers rely on resolving these domains to establish outbound communication for follow-on payload behavior. The detection relies on DNS query telemetry matching the configured suspicious domain names.
