Gremlins

Gremlins are supernatural creatures to whom mechanical malfunctions are attributed. During World War II air force pilots often blamed such technical difficulties on sabotage from the Gremlins. They were attributed a large number of disruptive abilities, such as the ability to siphon off fuel, cause instruments to give false readings, or raise and lower the runway by ten feet.

I imagine that modern gremlins have probably gone on to destroy and dismantle the wide variety of computers, video game systems, and other types of consumer electronics.
