Swiss researchers have demonstrated a variety of ways to eavesdrop on the sensitive messages computer users type by monitoring their wired keyboards. At least 11 models using a wide range of connection types are vulnerable.
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.
