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

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.

Discovered that the credentials for the library computers (which were helpfully printed on stickers for the forgetful librarians), were in fact domain admin credentials.

Gave myself a domain admin account, used that to obtain access to some sensitive teacher-only systems (mostly for the challenge, but also because I wanted to know what was going on my school report ahead of time).

My domain admin account got nuked, but presumably they didn’t know who had created it. Looked up the school’s vendor (“Research Machines Ltd.”) and found a list of default account credentials. Through trial and error, found another domain admin account. Made a new account (with a backup this time) and used it to install games on my classroom’s computers.

Also changed the permissions on my home directory so that the school’s teachers (who were not domain admins) couldn’t view my files, because I felt that this was too invasive at the time.

That last bit got me caught proper, and after a long afternoon in the principal’s office I left school systems alone after that for fear of having a black mark on my “permanent record”.

Somebody had put the Halo CE demo in some gym teacher’s shared folder and everybody in the school could access it and play LAN blood gulch

My HS put networked computers in every classroom a couple years before I graduated (so '95 or '96). The put predictable passwords on all the teacher accounts, and all teacher accounts had write access to network shares. Those of us who figured that out stashed copies of the Doom WAD file (the one file too big to fit on a single 3.5: floppy) all over the network under different names. So even after they figured out we were in and started forcing teachers to change their password, there were still a dozen or more copies spread over the network.

Student access was enough to copy the WAD file locally over the 100mbit ethernet if you knew where to look. And we all carried the rest of the game around on floppy. So any time we got access to the computers we were playing doom. We also passed around floppies with different mod files. The chicken launcher was everyone’s favorite.

The school computer were running Windows Vista, poor things didn’t need to be messed with.

Set up a Minecraft server back when you could run the Java files off of a USB. ran for a while, nothing fancy.

I also renamed every calculator icon to “cockulator”. Boy oh boy did I think that was funny back then. (it’s still a little funny)

I put tor on a flash drive. It bypassed the schools website blocks, so I could go onto any website I wanted. I mainly just went to YouTube to listen to music while I worked. If I really felt like goofing off, I’d go to friv.com and play a bunch of flash games.

Of course a couple friends had me to go to a porn website, but we quickly realized it was awkward and not as fun to be horny when you couldn’t do anything about it.

In college we had a Linux computer lab just for CD majors. At the time we had an HP printer that allowed for updating the screen text with a network command.

The computers were never really shut down, so you could just lock it when away. I wrote a script that cycled through various messages like “PC Load Letter” and “Skynet activated, stand by for terminator” with a countdown from 10 to “Terminator Deployed”.

It really confused the lab techs that would help people with printer issues.

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

Plugged one ethernet outlet to another on accident. But they were wired to the same dumb switch. So essentially I connected two switch ports together. This took the school network down for 4 days 😂

I worked IT in a high school for about 10 years. Here are some of the doozies:

• weed stashed in a PC case
• pop tart jammed into a DVD drive
• illicit domain admin account created by a student worker
• script to set porn to be the default background on reboot.

I believed that I was being unfairly marked with a biased grading.

I got access to admin privileges, found another students essay from the same class but different timeslot, knowing what grade they got after handing it in early, I changed nothing but the font and name and handed it in to get a full letter grade less than the original student had.

I couldn’t keep myself from complaining about it and was suspended over it, but it was a privilege when I knew I was right.

Edit: To clarify, it was the same teacher for both class groups.

Don’t know if it’s called messing with it but installed GTA and pretty much played that any chance I got. Also learnt that “sound” is just an additional aspect of a game I can get by without
