Russian hackers have created a USB stick that can instantly destroy any machine it is plugged into.
The USB stick created by a Russian security researcher known as 'Dark Purple' have uploaded a video to YouTube showing the USB in action.
In the video a researcher is seen plugging the USB stick into a working laptop, after a second or two the screen goes black and all attempts to get the laptop working again fail.
The USB destroys laptops by sending 220 volts through the signal lines of the USB interface, rendering anything it is plugging into useless.
