What it detects

This rule detects DNS queries to the trk.simitor wildcard infrastructure used in a DNS tunneling campaign that encodes tracking and victim data into MD5-hashed subdomains resolving through a CNAME chain. The abuse of DNS as a covert channel lets operators exfiltrate identifiers and beacon without conventional network egress. Detecting these lookups exposes tracking-oriented DNS tunneling activity.
