Hack Air-Gapped Computers Using Heat

An anonymous reader writes 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. BitWhisper bridges the air-gap between the two computers, approximately 15 inches apart that are infected with malware by using their heat emissions and built-in thermal sensors to communicate. It establishes a covert, bi-directional channel by emitting heat from one PC to the other in a controlled manner. Also at Wired.

The time it took them to increase the heat and transmit a 1 varied between three and 20 minute

So, somewhere between Comcast's Standard and High Speed plans.

Finally, malware that gives computers a fever.
