Another programmer gone bad story:

Man Arrested for ‘Whac-A-Mole’ Sabotage

Mallet-wielding children in arcades and amusements parks could be holding their weapons over mole holes in vain, waiting for a weasel that just won’t pop. If you run across a Whac-A-Mole arcade cabinet that becomes a dud out of nowhere, it might not be the arcade’s fault. A game programmer in Florida has been running a scheme since 2008, infecting Whac-A-Moles with a computer virus.

A Florida local news video on the story is available here.

This sort of thing can happen just about anywhere.  How to avoid it?  More on that later.
