USB charger that can steal bank details

For just £6, a hacker can create a covert device that tracks everything you type on a keyboard including usernames, credit card details and banking passwords.

The device, called KeySweeper, was built by a Poland-based security researcher and works with a range of wireless keyboards.

Once connected, the small USB wall charger remotely decrypts, logs and sends keystrokes to a hacker using specially designed software.
