Here’s one for the paranoia files:
There’s worrying news from the Security and Cryptography Laboratory at EPFL in Lausanne, Switzerland. We’re all familiar with the dangers of computer viruses and malicious software – just last week the FBI warned of the growing threat of computer crime. But it seems that one of the biggest threats to computer security could be the keyboard – even those that are not wireless.
Martin Vuagnoux and Sylvain Pasini have discovered that the electromagnetic waves released every time you strike a key on the keyboard can be detected by a nearby antenna and interpreted by computer software to work out exactly what was typed. Click “continue reading” to see a video.
So, be on the lookout for suspicious people with a giant antenna in the next room, especially if you type your passwords slowly o n e l e t t e r a t a t i m e. 😉 See the video: Compromising Electromagnetic Emanations of Keyboards Experiment 1/2 from Martin Vuagnoux. Snooping was worked out acoustically at least three years ago.
