For just a few bucks, you can pick up a USB stick that destroys almost anything that it's plugged into. Laptops, PCs, televisions, photo booths -- you name it.
Once a proof-of-concept, the pocket-sized USB stick now fits in any security tester's repertoire of tools and hacks, says the Hong Kong-based company that developed it. It works like this: when the USB Kill stick is plugged in, it rapidly charges its capacitors from the USB power supply, and then discharges -- all in the matter of seconds.
On unprotected equipment, the device's makers say it will "instantly and permanently disable unprotected hardware".
