Now security researchers have come up with an exploit that uses an even simpler form of radiation: heat. BitWhisper , as researchers Mordechai Guri and Professor Yuval Elovici of Ben-Gurion University's Cyber Security Research Center have dubbed their program, targets air-gapped machines—computers that are not physically (or wirelessly) connected to the Internet. By using malware that can tap into computers' cooling systems and temperature sensors, the hack can send information back and forth between two adjacent machines. For example, raising the temperature of one computer by a single degree over a
