Exfiltrating Data from Air-Gapped Computers via Wi-Fi Signals (Without Wi-Fi Hardware)

A security researcher has demonstrated that sensitive data could be exfiltrated from air-gapped computers via a novel technique that leverages Wi-Fi signals as a covert channelsurprisingly, without requiring the presence of Wi-Fi hardware on the targeted systems. Dubbed “AIR-FI,” the attack hinges on deploying a specially designed malware in a compromised system that exploits “DDR SDRAM buses
