CommSec D1 - Steganography Ante Portas
summary
A survey of decades of papers yields an explicit taxonomy of eleven covert-channel size modulation and value modulation patterns plus timing varieties like inter-arrival time manipulation; Europol-backed CUING coordinates forensic responses. Demonstrations include microprotocol-based overlay networks to tunnel through firewalls, malware-grade carriers in messenger and SSH-like traffic, and a smart-building proof that stores roughly 350–1,500 bits (author reports ~30 actuators needed to persist a 128‑bit key). Open problems: new patterns, pattern-based countermeasures, and boosting CPS storage capacity.
