A warning is being issued by the security firm Symantec over a potential problem that could affect users of the Microsoft and Logitech wireless keyboards.
The problem is coming from a group named remote-exploit.org, which has been working on an open source project for almost two years that can effectively intercept all of the keystrokes made on a wireless keyboard using the 27 MHz wireless radio transmission frequency.
It works by analysing the electromagnetic patterns that occur when the wireless keyboard is being used.
The good news is that the device has to be around ten metre away from the target in order to read the signals.
The bad news is that each keystroke can be picked up, including passwords and just about anything else that is typed on the keyboard.
You may or may not have heard about, Tempest, a spec for military and other computers used in secure places, banks etc, which reduced or eliminated emissions from keyboards and computers. It was demonstrated way back in the 1980′s on the BBC’s Tomorrow’s World, how easy and cheap it is to read what’s being typed on a computer from some distance away. Outside an office for example. However this was from reading the screen rather than the keyboard but keystroke reading devices were around then. However, in security circles it’s generally accepted that the easiest way to get info from a computer is to pay someone!
