At my school, we quickly discovered that the admin password for all the networked printers was the name of the high school. All these HP laser jets had a function where you could upload custom translations for the status messages on the printer displays. So we downloaded the English string set (XML) and made some changes, “translating” for example, “Printer Ready” to read “Paper Jam”, “Replace Toner” and so on. As well as changing the admin password. The school actually RMA’d them back to HP thinking the paper jams were some sort of actual defect, as opposed to an altered status message, and eventually replaced them all with Brother printers. Oops lol

for several days in a row i’d get to class before the bell. the teacher would hang out in the halls.

i’d hop on his unlocked PC, open command prompt, run shutdown /r /t 600, minimize the prompt, and walk away.

he’d be mid attendance and his computer would reboot on him. a few days in he stepped into the room mid me typing the command. he was madder than i expected, but just “yelled” at me.

When I was in middle school in the mid ‘90s, the school library decided to go digital. They installed a bunch of computers with what they called “a boolean search system”. For the first time, you could search for a book by topic in the library and, after a bit of a wait bc computers were pretty slow back then, you’d get a list of results.

Well, us being kids, on the very first day, somebody decided to search for “book”, which of course matched every single book in the library and therefore created enough system load to lock up those poor mid-‘90s computers to the point that they required a hardware restart. IIRC this system was on some kind of a network too and I believe it would also lock up the network such that the other computers couldn’t use the system either. I didn’t know much about such things at the time.

Anyway, word got around immediately and so every single time a class came to the library, somebody would search “book” on a computer to see what would happen and lock up the whole system for hours. This went on for weeks with the punishment for searching “book” on the “boolean search system” becoming more and more severe, and then I moved to a new state so I unfortunately do not know how this story ended.

Create a folder with intriguing name on desktop, take screenshot, set screenshot as wallpaper, delete folder. (Didn’t everyone?)

Take a screen shot of the desktop. Set that screen shot as the desktop background and delete some of the icons/shortcuts.

Gained access to the school’s domain admin account and fucked with th teachers remotely via Tor.

Wanted to access the teachers calendar because he was a fucking Nazi and stumbled upon VPN credentials to a government-run education network and could’ve leaked hundreds of thousands of pupil’s personal data and school grades but decided against it and shared with admins how I got in and told them how to fix it. Never got into his calendar though. 😶
