Keyboard "eavesdropping" just got way easier, thanks to electromagnetic emanations
Engadget —
... We always knew those electromagnetic emanations would amount to no good, and now here they go ruining any shred of privacy we once thought to possess. Some folks from the Security and Cryptography Lab at Switzerland's EPFL have managed to eavesdrop on the ...
Electromagnetic Scanners Can Detect What You're Typing Right Now [Security]
Gizmodo —
... It's obvious to assume that your henpecking on a wireless keyboard could be intercepted by a RF-snooping ne'er-do-well, but what about your wired or laptop keyboard—that should be safe, right? Nope. Researchers at Lausanne, Switzerland's Security and Cryptography Laboratory (part of the EPFL school) have demonstrated here that 12 different keyboards, bought from 2001 until now, can be eavesdropped upon by monitoring their electromagnetic signatures—wirelessly, from up to 65 feet away, through walls. ...
Researchers devise methods to sniff keystrokes by detecting shifts in magnetic field
CrunchGear —
... Two doctoral students have produced what is probably the most fascinating hack (or whatever you want to call it) of the year. Using custom equipment and software, Messrs Martin Vuagnoux and Sylvain Pasini of the Swiss Ecole Polytechnique Federale de Lausanne are able to detect shifts in the magnetic field surrounding keyboards. By measuring and interpreting these shifts, the students are able to figure out what has been typed. There’s four such “attacks,” once of which can work from as far as 20 meters (65 feet). ...

... from 2001-2008 which were all vulnerable to at least one of their 4 attacks.
“To determine if wired keyboards generate compromising emanations, we measured the electromagnetic radiations emitted when keys are pressed. To analyze compromising radiations, we generally use a receiver tuned on a specific frequency. However, this method may not be optimal: the signal does not contain the maximal entropy since a significant amount of information is lost.”
