Keystrokes from wireless keyboards transmit with no encryption and can be intercepted from hundreds of feet away

Users of non-Bluetooth wireless keyboards are being warned of a potentially serious vulnerability that could allow their typing to be intercepted.

Bastille Networks tested a number of wireless keyboards from vendors including HP, Radio Shack and Toshiba, and found the flaw that it has called KeySniffer.

The problem stems from the fact that a wide range of these wireless keyboards use unencrypted radio communications that can be easily intercepted by a cheap USB radio antenna costing less than $100 £76 .

The researchers were able to intercept user keystrokes and reportedly they could even control the wireless keyboard and insert their own keystrokes.

The potential security risk this presents is obvious.
