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 channel—surprisingly, without requiring the presence of Wi-Fi hardware on the targeted systems. Dubbed "AIR-FI," the attack hing...

Keystroke Recognition Uses Wi-Fi Signals To Snoop

A group of academic researchers have figured out how to use off-the-shelf computer equipment and a standard Wi-Fi connection to sniff out keystrokes coming from someone typing on a keyboard nearby. The keystroke recognition technology, called WiKey, isn’t perfect, but is impressive with a reporte...
