A new white-paper published by Remote Exploit highlights how it is possible to remotely intercept signals from wireless peripherals such as keyboards. The security hack works only against keyboards using radio technology operating on a radio frequency of 27Mhz, which was previously thought to be secure from most casual attacks. The white-paper demonstrates how it is possible to use a simple radio receiver, a sound card, and some basic PC software to intercept these signals and reveal what users have been typing. While Bluetooth is safe from this vulnerability, companies such as Microsoft and Logitech still continue to use the tradition radio technology.
