Every time you press a key on your keyboard, a small burst of electromagnetic radiation is let out. This radiation can be captured and decoded. Though it only affects some models, this is pretty serious. They tested 11 different keyboards and they were all vulnerable to at least one of the four methods of attack. Tests have shown that the data can be read through walls and up to 65 feet away. That is pretty scary stuff. Someone could be setting up in the apartment or office right next to yours to listen to every keystroke you type.  Check out the second video after the break.

They don’t give a list of what keyboards were affected. Their paper is currently being finished, and should be published soon. The possibility of this attack was suggested to us a couple years ago when we covered old school Van Eck phreaking.
