Security in Industry 4.0: The IoT Blind Spot

Passive intelligence gathering via OT telemetry reveals critical blind spots in Industrial Control Systems. This paper investigates how boiler sensor data and PLC communications can be intercepted and thermodynamically modeled by adversaries, and proposes countermeasures for securing operational technology environments against stealthy reconnaissance.
