Anti-Electronic Spike (D20 Modern Equipment)
From D&D Wiki
Approximately the size of a hand grenade, an anti-electric spike resembles a grenade with a USB port on one end. When the device is attached to a computer and activated, it releases three quick surges of electricity that wreak havoc on a computer system, shutting it down until a Repair check (DC 20) is made. The spike is useful in quick operations, but is rather unwieldy at times, since its interference with a computer system can almost never be disguised.
