Let's Talk Through Physics! Covert Cyber-Physical Data Exfiltration on Air-Gapped Edge Devices. (arXiv:2210.07531v1 [cs.CR])

Although organizations are continuously making concerted efforts to harden
their systems against network attacks by air-gapping critical systems,
attackers continuously adapt and uncover covert channels to exfiltrate data
from air-gapped systems. For instance, attackers have demonstrated the
feasibility of exfiltrating data from a computer sitting in a Faraday cage by
exfiltrating data using magnetic fields. Although a large body of work has
recently emerged highlighting various physical covert channels, these attacks
have mostly targeted open-loop cyber-physical systems where the covert …
