Van Eck phreaking is a concept that's been around for over 20 years. It refers to the practice of remotely capturing the electromagnetic signals radiated by a computer monitor and reverse engineering the signals to reproduce the image on a second monitor. First proposed by Dutch computer scientists Wim van Eck in 1985, the concept is more than just a theory and can present a real threat to sensitive information. Now two doctoral students at the Ecole Polytechnique Fédérale de Lausanne in Switzerland have applied a similar type of technique to detect the signals emitted from wired keyboards when the keys are pressed. While the idea has been thought theoretically possible, the two students believe this is the first time it has been demonstrated to be feasible. Using different techniques they were able to pick up and reproduce the typed text from 11 different keyboards, including laptop keyboards, from up to 20 meters away. Sounds like it may be time for the more paranoid among us to begin work on that giant Faraday cage you've always wanted.
