Another nail in the coffin of assuming that airgapped means secure Share Copy Mordechai Guri, an Israeli cyber security researcher who focuses on covert side channel attacks, has devised yet another way to undermine air gapping – the practice of keeping computers disconnected from any external network for the sake of security. In a newly released working paper [PDF], "AIR-FI: Generating Covert Wi-Fi Signals from Air-Gapped Computers," Guri, head of research and development at Ben-Gurion University of the Negev, Israel's Cyber-Security Research Center, describes a technique for turni...

Named  AIR-FI, the technique is the work of Mordechai Guri, the head of R&D at the Ben-Gurion University of the Negev, in Israel. Over the last half-decade, Guri has led tens of research projects that investigated stealing data through unconventional methods from air-gapped systems. Also: These types of techniques are what security researchers call " covert data exfiltration channels." They are not techniques to break into computers, but techniques that can be used to steal data in ways defenders aren't expecting. Such data exfiltration channels are not a danger for normal users, but the...
