Researchers demo wireless keyboard sniffer for Microsoft 27Mhz keyboards

Researchers from Remote-Exploit.org, the home of the BackTrack pen-testing Linux distribution, have recently released an open source wireless keyboard sniffer Keykeriki, capable of sniffing and decoding keystrokes of Microsoft 27Mhz based keyboards through on-the-fly deciphering of XOR based encryption.

Their wartyping — decoding signals from wireless keyboards — proof of concept is based on a research paper published by the group one and a half years ago:

“Now 1.5 years after releasing our whitepaper “27Mhz Wireless Keyboard Analysis Report” about wireless keyboard insecurities, we are proud to present the universal wireless keyboard sniffer: Keykeriki. This opensource hardware and software project enables every person to verify the security level of their own keyboard transmissions, and/or demonstrate the sniffing attacks (for educational purpose only). The hardware itself is designed to be small and versatile, it can be extended to currently undetected/unknown keyboard traffic, and/or hardware extensions, for example, a repeating module or amplifier.”
