Israeli boffins hack air gap - Slow command and control code uses PC hot spots to murmur secrets
One of the weirder attacks to bridge air gap networks has emerged, and uses heat to transfer data between machines.
The command and control mechanism forged by Ben Gurion University researchers could transfer sensitive data through "thermal pings" between two physically close computers.
Like many air gap bridges, the so-called BitWhisper attack is limited in that it requires malware to be installed on the sending and receiving machines in order for the very slow data exchange to take place. Researchers in a demonstration video shows how BitWhisper can be used to trigger a USB toy missile launcher to rotate and fire.
