Remotely Eavesdropping on Keyboards
The researchers from the Security and Cryptography Laboratory at Ecole Polytechnique Federale de Lausanne are able to capture keystrokes by monitoring the electromagnetic radiation of PS/2, universal serial bus, or laptop keyboards. They’ve outline four separate attack methods, some that work at a distance of as much as 65 feet from the target.
In one video demonstration, researchers Martin Vuagnoux and Sylvain Pasini sniff out the the keystrokes typed into a standard keyboard using a large antenna that’s about 20 to 30 feet away in an adjacent room.

Toggle switches on the front panel, anyone?
Seriously though, tempest isn’t new. If it’s been possible for a long time to decode video, keyboard traffic shouldn’t be too difficult.
