Nothing crazy or software related, but screwing with people with a wireless mouse with one of those tiny receivers is pretty funny.

Background on a lab to a high resolution naked mole rat picture zoomed in so it kinda looked like a scrotum maybe, but it wasn't: It was just a naked mole rat.

Every computer had passworded but active local administrator account, so I think I went with the "how to reset forgotten password" (win7) and arrived to Trinity Rescue Kit, burned it to CD and went on with rebooting and cracking, I didn't have the balls to change the admin pass to my own, just left it empty.

Even got some good snacks for unlocking others assigned computers so that they could install whatever they wanted, mostly counter strike.

Our school used to have a central windows server host and virtual environments for each student seat. They all had only a monitor mouse and keyboard that connected to the server using a username (all started with stu and then the number of the seat) but had no password.

A buddy of mine then went ahead and made a .bat script that somehow simultaneously tried to connect to all student seats, resulting in each of the screens blacking out one by one for a while, then going back to normal.

I ran it for shits and giggles at the end of class, and the teacher saw it, didin't understand what happened initially, got really angry and walked into a few chairs tripping up trying to catch us, and then took us to write a report with the school secretary. I love this teacher, this was one of the funniest moments in school.

Installed Real VNC server on the machine next to us and connected to it with a small Real VNC viewer window. We moved the mouse over the viewer window from time to time to fuck around with the guy who was using the "target" PC. IIRC we also did the classic desktop screenshot wallpaper prank. In the end they formatted the machine.

Replaced the Windows 95 boot screen with an exact copy where a single black square was changed to red.

Net Send * Hello

Mix that with a c++ loop of While 1 and you have every computer in the school lock up before crashing the network.

Dropped some extensions on the Mac image servers, toyed with Next machines, all kinds of shenanigans.

would put portable games on the public network share, apparently they didn't have logs of people putting stuff there

A bunch of people at my school would flick the power input switch on the back of the PCs to 110v (240v native in my country) while they were off and wait for an unsuspecting person to come by and boot it up. It'd obviously go bang and start smoking and they'd freak out not knowing what they did to cause the PC to blow up.

Shit move, but having witnessed the shear horror of someone who thought they caused it to blow up was kinda funny.

Modified autoexec.bat (to run a choice with errorlevel excluding to continue all keyboard keys except capital S) with some ASCII art and writings of a virus infection...was the only pc in school at that time...pc got wiped and reinstalled...no one was thinking of exiting the script the stupid way and look around for the causes.

We installed quite a few games on the backend server.

• worms
• Unreal tournament
• doom
• Quake

And a few others. They were there for years, if they were deleted we had backups in multiple spots had them there for at least 4 years.

we installed Duke Nukem 3D on all of the computer lab pc's

I edited autoexec.bat to put it in to an endless loop :P

We had a small computer room with about 30 computers so I ran a dedicated server for CS 1.5 and told all my grade the ip which they used to connect Counterstrike from a usb. This was back in 2006. We would see people connect from the library and other school computers. Was alot of fun running admin mod.

The term "Xennial" always resonated with me. We were the ones that were on the cusp of the ending of the Gen X era and the beginning of the the Millenial era. Also 1979 here.

Kept removing the web filter proxy from all the browser settings lol the it guy got pissed all the time but didn’t have a way to stop us

Apparently changed my grades. I really don’t remember this but my Mom reminded me the other day. Luckily this was the 90s and nothing came of it.

On a school Mac I figured out using some command I could create a new admin account. I used this account to gain access to the school WiFi password and admin account password. I found out what a vpn was and brought my own laptop to us instead of the crappy ASUS Eee PC netbooks. The Vice Principal was not happy. They called my parents for a meeting ( I had a lot of issues with many IEP meetings). My parents were okay with it.

We would also pass around pirated GTA 3, GTA Vice City, Free versions of Minecraft, and Halo CE and run them off of USBs.
