It's amazing-Heat can be used to hack computer!! Researcher develop technique for stealing data from computers which are not connected to Internet using heat generated by them Stealing from computers not connected to internet became that much more easier using the new technique found by security researchers from Ben Gurion University. Security researchers from Ben Gurion University in Israel have found a way to retrieve data from air- gapped computers i.e. computers not connected to internet, using only heat emissions and a computer’s built-in thermal sensors. The research team consists of Mordechai Guri, Gabi Kedma and Assaf Kachlon and are overseen by their adviser Yuval Elovici. Together they have devised a method which could be used potential hackers to steal passwords from a protected system and transmit the stolen data from a internet connected PC in close proximity to their command and control center. Computers produce varying levels of heat depending on how much processing they’re doing. PCs have built in thermal sensors to monitor such heat and give commands to the internal fan to start or switch off. The attack, which the researchers dubbed # bitwhisper , uses these sensors to send commands to an air-gapped system or siphon data from it. The technique works a bit like Morse code, with the transmitting system using controlled increases of heat to communicate with the receiving system, which uses its built-in thermal sensors to then detect the temperature changes and translate them into a binary “1” or “0.”
