Ben-Gurion University of the Negev (BGU) researchers have discovered a new method to breach air-gapped computer systems called “BitWhisper” which enables two-way communications between adjacent, unconnected PC computers using heat.
The research, conducted by Mordechai Guri, Ph.D. is part of an ongoing focus on air-gap security at the BGU Cyber Security Research Center. Computers and networks are air-gapped when they need to be kept highly secure and isolated from unsecured networks, such as the public Internet or an unsecured local area network. Typically, air-gapped computers are used in financial transactions, mission critical tasks or military applications.
