Experts Hacked Air-Gapped Computers Using Heat

March 26, 2015 | Ben Gurion University researchers discovered a new way to hack air-gapped  computers (which are not connected to the internet). Their method, dubbed “BitWhisper,” enables two-way communications between adjacent, unconnected computers using heat. This new method could potentially help intelligence agencies. The research was conducted at BGU’s Cyber Security Center by Prof. Yuval Elovici and Mordechai Guri.
