KeySniffer is a set of security vulnerabilities affecting non-Bluetooth wireless keyboards from eight vendors. The wireless keyboards susceptible to KeySniffer use unencrypted radio communication, enabling an attacker up to several hundred feet away to eavesdrop and record all the keystrokes typed by the victim. This means an attacker can see personal and private data such as credit card numbers, usernames, passwords, security question answers and other sensitive or private information all in clear text. The equipment needed to do the attack costs less than $100 putting it in reach of many teenage hackers.
The keyboard manufacturers affected by KeySniffer include: Anker, EagleTec, General Electric, Hewlett-Packard, Insignia, Kensington, Radio Shack and Toshiba.
