    For the last few years, researchers from Ben-Gurion University of the Negev have been testing up new ways to exfiltrate data from air-gapped computers: via mobile phones, using radio frequencies (“AirHopper”); using heat (“BitWhisper”), using rogue software (“GSMem”) that modulates and transmits electromagnetic signals at cellular frequencies. The latest version of the data-exfiltration attack against air-gapped computers involves the machine’s fans. Dubbed “Fansmitter,” the attack can come handy when the computer does not have speakers, … More →
