Cyber Security Research Labs at Ben-Gurion University has developed an attack on air-gapped systems. The new AIR-FI attack allows criminals to steal data by generating a Wi-Fi signal in the 2.4 GHz range through memory buses. No dedicated hardware is necessary to make the attack possible. The lab has been doing this kind of research for a long time, developing ways to leak data by using keyboard lights, the HDD led, and even screen brightness changes. A few months ago, the researchers developed a way to turn power supplies into speakers.”]
