Russian USB Stick Destroys Computers
A simple USB stick, created by a Russian security researcher known as 'Dark Purple' can instantly fry any machine it plugs into, including your laptop or TV.There is more information at the link.
In the short video posted by the hackers, the USB is shown in action - all it takes is plugging it into the hacker's IBM laptop, and it completely kills the machine within seconds.
After the laptop turns off, the demonstrator in the video tries repeatedly to turn it back on but it seems that the USB has blown its circuitry in the process.
The USB destroys laptops by sending 220 volts through the signal lines of the USB interface, rendering anything it is plugging into useless.
