Cipher Brief Academic Incubator student Mason Goad writes about the importance of Tempest Standards in The Cipher Brief

The latest in a series of unorthodox methods uncovered over the years on December 20, 2020, 6:56 10 comments Why it matters: Air-gapped computers, usually found in government, banking, enterprise, industrial and military setups, operate in tightly controlled environments, cut-off from the internet and under strict supervision. You'd normally think they're safe from information leaks, however an Israeli security research team has proven once again that all it takes is some creativity. Earlier this year, a group of Israeli security researchers at the Ben Gu...

By Ionut Arghire on December 16, 2020 Covert Wi-Fi signals generated by DDR SDRAM hardware can be leveraged to exfiltrate data from air-gapped computers, a researcher claims. In a newly published paper, Mordechai Guri from the Ben-Gurion University of the Negev in Israel details AIR-FI, a new data exfiltration technique in which malware installed on a compromised air-gapped system can generate Wi-Fi signals that a nearby device intercepts and sends to the attacker, over the Internet. The technique leverages memory buses for the generation of covert signals, thus eliminating the need of Wi-Fi...

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...
