KeySweeper Claims the Ability to Eavesdrop on Microsoft Wireless Keyboards

Have you ever wondered whether you can trust the security of wireless keyboards? Samy Kamkar has released the schematic and source code for a device called KeySweeper, a device that looks like a USB wall charger, but claims the ability to intercept and decrypt all keystrokes from any Microsoft wireless keyboard in the area. If true, it would mean no Microsoft wireless keyboard is safe at the moment. The code is posted on GitHub, and according to Samy, a basic version of the device could be built for as little as $10. The device even features an internal battery, which means it could sniff keystrokes without even being plugged in.
