KeySweeper – covert Microsoft wireless keyboard sniffer using Arduino and nRF24L01+

Samy KamkarĀ has written an article detailing the build of hisĀ KeySweeper project:

KeySweeper is a stealthy Arduino-based device, camouflaged as a functioning USB wall charger, that wirelessly and passively sniffs, decrypts, logs and reports back (over GSM) all keystrokes from any Microsoft wireless keyboard in the vicinity.
All keystrokes are logged online and locally. SMS alerts are sent upon trigger words, usernames or URLs, exposing passwords. If unplugged, KeySweeper continues to operate using its internal battery and auto-recharges upon repowering. A web based tool allows live keystroke monitoring.

Files and source code available at Github.
