Cellphones can steal data from isolated "air-gapped" computers


Homeland Security News Wire - (International) Researchers at the Ben-Gurion University of the Negev Cyber Security Research Center discovered a way to use central processing unit (CPU) firmware-modification software to turn an air-gapped system into a cellular transmitting antenna, making it possible for any mobile phone infected with malicious code to use GSM phone frequencies to steal data from infected air-gapped systems. Researchers recommended mitigation measures including defined "zones" where mobile phones and other devices are not allowed near at-risk air-gapped computers.
