Last year, a white hat hacker developed a cheap Arduino-based device that looked and functioned just like a generic USB mobile charger, but covertly logged, decrypted and reported back all keystrokes from Microsoft wireless keyboards.
Dubbed KeySweeper, the device included a web-based tool for live keystroke monitoring and was capable of sending SMS alerts for typed keystrokes, usernames, or URLs, and work even after the nasty device is unplugged because of its built-in rechargeable battery.
