passwdResearchers from Cyber-Security Research Center at Ben-Gurion University have created bridgeware that can stealthily exfiltrate data from air-gapped computers using power lines.
In their POC, a malicious code is running on a compromised computer system which has control over the power consumption by intentionally regulating the CPU utilization. In this case data is modulated, encoded, and transmitted on top of the current flow fluctuations, and then it is conducted and propagated through the power lines.
In their paper the researchers present two versions of that attack:

  • Line level power-hammering: In this attack, the attacker taps the in-home powerlines that are directly attached to the electrical outlet.
  • Phase level power-hammering: In this attack, the attacker taps the power lines at the phase level, in the main electrical service panel

A research by Mordechai Guri and Prof. Yuval Elovici from the Cyber Security Resarch Center at Ben-Gurion University found a new way for jumping the Air-Gap.

This time they are doing this by using the heat emissions and a computer’s built-in thermal sensors.
