Wired keyboards, like those found on desktop PCs, emit electromagnetic waves that can be read remotely, according two Swiss researchers.
Researchers Martin Vuagnoux and Sylvain Pasini of the Swiss Security and Cryptography Laboratory at LASEC/EPFL, were able to recover keystrokes from wired keyboards at a distance up to 20 meters (about 65 feet), even through walls, simply by reading the electromagnetic emanations of the peripheral device. The experiments focused on wired keyboards attached to a computer either by PS/2 or USB connections.
In two videos, Vuagnoux demonstrates the attacks.
In the first video, he shows how only the … Read more
