Analytic 2243

Detect embedded hooking by correlating an independently acquired firmware/module integrity measurement that differs from the approved vendor/baseline image with protocol-response behavior that also departs from the device's known deterministic behavior. A protocol-response anomaly by itself does not prove a hook because firmware versions, device state, communications faults, and vendor-specific behavior can produce response differences. Treat network anomalies as corroboration and require independent integrity evidence or vendor/device attestation before escalating the condition as firmware-level hooking. Monitoring mode: periodic or event-triggered integrity verification plus near-real-time protocol monitoring where a capable OT protocol decoder is deployed.
