When our school started to provide network shares to students, they were pretty lax on security. I figured out that everyone's share was publicly read/writable, and the network path was pretty easy to guess. Whenever someone would annoy me I would replace a project file they were working on with some matter of nuisance program, like a zip bomb or a script that just kept opening word until the system ran out of ram. I'm surprised I never got caught, because I was too much of an idiot to properly cover my tracks.
