Air-Gapped Computer Hacked (Again)

An anonymous reader writes: Researchers from Ben Gurion University managed to extract GSM signals from air gapped computers using only a simple cellphone. According to Yuval Elovici, head of the University’s Cyber Security Research Center, the air gap exploit works because of the fundamental way that computers put out low levels of electromagnetic radiation. The attack requires both the targeted computer and the mobile phone to have malware installed on them. Once the malware has been installed on the targeted computer, the attack exploits the natural capabilities of each device to exfiltrate data using electromagnetic radiation.
