As if lose USB drives with the potential for spyware and malware are not bad enough, some mad genius decided to build a USB device that is technically capable of doing damage to the hardware components of most modern computers. The device was custom built by a guy named Dark Purple and consists of a DC to DC converter and a capacitor bank. There is some control logic to this so that the capacitor bank know when to send the death note to the system it is plugged in to.
