Air-gapped computers can communicate through heat: Researchers

2015/03/24

Securityweek - (International) Researchers at Israel's Ben Gurion University demonstrated that it was possible to establish a bidirectional communication channel between two unconnected computers using heat and radio signals emitted from components such as the central processing unit (CPU) and graphics processing unit (GPU), allowing an attacker to use malware installed on each system to exfiltrate data from an air-gapped computer, dubbed BitWhisper.
