Two years ago when I joined college, I needed a way to get my assessment files (some stupid movie and an essay which I should have copied over USB) from my house to college quickly. I had to stupid idea to use a P2P network and got my friend to set one up from my house; it ended up killing the entire college network for 10 minutes because apparently the Administrator had put the most ridiculous netcode in that physically reboots the modem(s) if it detects certain types of network behaviour.
Four weeks ago, a virus spread through the college computer network. Some kind of Trojan. Everytime one computer's copy of Norton Antivirus would clean it, because other PCs were slower they would just resend the virus and so there was a giant, unstoppable loop. Apparently the Admin was too lazy/stupid to turn off the computers and clean them one-by-one, so I decided to not do his job.
Three weeks ago, I discovered something very interesting. On the computer I was using to work on Unreal 4 stuff, some idiot had downloaded uTorrent Portable and Jupiter Ascending. I didn't think much of it at the time so I chuckled and deleted the files (the HDDs on these computers are absolutely pitiful and full to the brim with student art projects).
The next week, uTorrent Portable and Jupiter Ascending were back, but this time they were also joined by The Devil Wears Prada and Mrs Doubtfire. I also found a suspicious .exe file (one of those that claims to have a song download). I uploaded it to one of those online file scanners, and the results came back positive for the exact same Trojan infection we had before. I deleted all the files and left a text note titles "DON'T BE A loving handicap.TXT".
Today, a friend messaged me from college. He was sitting at the computer next to the one I usually use, and apparently uTorrent Portable was back with the three movies and a different-but-similar suspicious .exe. He also said the virus probably hasn't been fixed.
What weird stuff do people do in your schools with technology?
