Some people at the Security and Cryptography Lab at Switzerland’s EPFL have managed to capture the EMF (Electro-Magnetic Radiation) comming from wired computer keyboard. OK, we all know that if we used a wireless keyboard that any old FBI Agent - or hacker could easily catpure the signals being transmitted by the keyboard. But now they have figured out how to capture the pressed keys from a wired keyboard.
What next? They’ll be able to see what I’m doing on my screen too? It’s not that far fetched.
The tests were run in a fairly EMF free zone (There were no other devices around such as monitors, mobiles and other devices that give off strong electromagnetic waves), they were also, but the looks of it were using a unidirectional antenna (A “Tunnel Vision” antenna).
The expirement was tested on laptops with the embedded keyboards, and external USB/PS2 keyboards. They have so far managed to work out 4 different ways to grab our data fom a range of approximately 20 meters.
I believe this is just the start of this sort of technology. Hmmm… this gives me even more of a reason to live inside a faraday cage…
Below is a screenshot of the working software from the video:

Here’s a picture of one of the larger antenna’s used:

There are some videos on this site about this.
