DNS tunneling often appears as high-volume TXT queries, unusual subdomains, odd query lengths, and traffic to rare domains. Baseline DNS behavior and alert on entropy spikes.

Eliminate capture loss by isolating ingest, indexing, and storage paths; tune NIC queues, buffers, and write pipelines to sustain line-rate packet capture at scale.

Spot HTTPS beaconing by correlating periodic connections, uniform payload sizes, rare domains, and JA3/JA4 fingerprints-without decrypting traffic.

Best practice: decrypt SSL/TLS at a controlled proxy, enforce certificate validation, exclude sensitive categories, and log keys securely for targeted security inspection.

Trace lateral movement by filtering SMB, RDP, WinRM, and DNS in Wireshark, then correlate suspicious logons, host pivots, and credential use to map attacker paths.
