I was in college during the years leading up to y2k and supported myself at the time getting IT infrastructure ready. Some friends and I decided to write a "virus" that, on bootup, checks to see if the current date is in the first week of January 2000 and if it is and a backup of the fonts is not found (so it'll only run once) then it'll back up your fonts and alter the originals to replace the y character with the k. This affected everything system wide.

That created more chaos than anticipated.

We used to edit the system keymapping on the school Macintoshes and duplicate a letter somewhere, and then we’d do the same to a second machine using the letter that the first could no longer type; then we’d switch the physical keycaps

I had a boss that wasn't exactly technical. I wrote a power shell program that would randomly every 5-30 minutes give a pop-up that said "good job", which he always said regardless of what was going on. Placed it in his startup folder on his machine. I thought he would figure it out and tell me to knock it off.... Well I forgot about it, 9 months later during my annual performance review it popped up while I was looking at his screen. He apologized and just alt tabbed it away.

I offered to take a look and see if I couldn't stop it, and he said yes and then walked away to take a break. I then deleted the script I put on there. He gave me extra performance points (meaning a higher pay raise.)

I Rick Rolled my entire school this way. Write a program that maxed the volume and held it there at 100%, minimised all open windows, downloaded a photo of Rick Astley and set it as your wallpaper, then started playing Never Gonna Give You Up. The only way to stop it was to power off the computer or wait the song out, then manually fix your wallpaper.

I saved the executable in a publically accessible location on the school's server that I shouldn't have had write access to, and sent a cleverly disguised link to a mate. He thought it was hilarious, and forwarded the email to a dozen of his mates. They forwarded it to all their mates, and pretty soon no teacher could go 60 seconds without another one of their students' laptops interrupting the class at max volume.

Best bit? I "taught a valuable lesson in cybersecurity" and didn't get in (much) trouble!!

I'm still irritated about when I was a youth I found a somewhat obvious security hole, and took advantage of it in a mildly funny way, the staff just punished me.

You weren't supposed to be able to change the desktop background, but for some reason MS Paint had a "set to background" option that worked. So I set the background to a screenshot of the desktop, and then hid all the icons and start menu. Later, the teacher thought the computer was broken because "nothing was working".

I think it could've been a good teaching moment. A talk about not messing shared resources up, and channel my interests somewhere productive. Nope. Just a lecture and week long library ban. Disappointed.

In a programming class, one of my professors sometimes remolety opened the xeyes program (Linux program that opens a pair of eyes that follow your cursor) on students that were not paying a lot of attention.

[–] [email protected] 33 points 1 week ago

Thank you, I have wondered why xeyes existed for the last 28 years.

I used to operate a dashboard on a wall-monitor in an IT ops center. For Halloween, I wrote a script that very briefly played a video of a creepy set of eyes that opened, looked around the room, focused on something/glared, then closed, all over around like 2 seconds, but ran 1-3 times an hour. It was funny the first few times it happened and I got told to turn it off.

Instead I changed it to run 1-3 times a year.

My manager thought that that was absolutely hilarious without being too disruptive and let me keep it. We had enough turnover that there was always a newbie in the pool and every now and then, someone would say 'what the fuck was that!?' and we'd get a good laugh.

I wrote a simple script once that ran in the background and all it did was toggle the state of the caps lock key every 30 minutes. I set it up on a co-worker's computer as a scheduled task for an April Fools prank one year. I thought for sure he'd figure it out pretty quickly, but by mid-day, he had completely disassembled his keyboard, convinced the button was getting stuck due to gunk buildup. Eventually I ended up just disabling the task so he thought he had managed to fix it himself.

Oh, I have a seemingly harmless idea so evil, it will ruin the internet forever.
I will make it so every time you open any website, there will be a popup with a question that asks you to invade your privacy, and you can allow it to do so with one click, but you will have to dig through menus if you want to avoid it. Then, after some seconds, another popup will appear, asking you to create a login, no matter what you do. Then, it randomly will ask you to share your location. Yes, with a popup again. Then, just as you thought you're done, another window will open, grabbing your focus, which will demand you talk to a chatbot, and you can't close this one, only slightly minimize it.

[–] [email protected] 17 points 1 week ago

You should add one allowing this site that you've never been to before and don't even know yet if it's useful, to send you notifications.

[–] [email protected] 12 points 1 week ago

Also, autoplaying videos that pop up in the lower corner of your screen. It has a clear, easy to click “X” button to close, but every 100 px you scroll triggers a re-check of the video window to ensure it’s still open and playing. If it’s been closed or stopped, the pop up window respawns and/or the video restarts.

I remember a harmless over that just randomly opened your CD tray while it ran. Called something like cup holder, or something like that.

Shit that was a long time ago...

I had a friend who sent me a "Y2K fix" program back in '99. Said it would patch the error so I'd be safe. When I ran it, it swapped the letters Y and K on my keyboard.

Three options come to mind.

A virus that adjusts your mouse sensitivity by like 5% every time you unlock your computer. Just enough that existing muscle memory is off, so you either have to adjust to the change or change it back every time.

A virus that installs and/or sets a similar but not quite right keyboard layout, and swaps to it randomly few boots. For example, setting the keyboard to Canadian Multilingual Standard instead of US English, where its only some of the punctuation keys that are changed.

A virus that randomly pops up a terminal window and outputs suspicious-looking text, and closes itself before the user has time to read it.

Every time you log in, maximize a window, lock your PC, etc, your desktop icons randomly arrange themselves by penis. Open a folder, forced to display files as icons and arranged by penis. Try to view all your open windows on your desktop, you guessed it, penis.

[–] [email protected] 22 points 1 week ago (1 children)

No, no, change it back! I had internet explorer at the tip of penis

Chip, you can't arrange by penis

Just change it back okay

There was a guy in my dorm who really didn't like his roommate. Really, really didn't like him. This was in the early aughts.

So one day he goes on his roommate's computer and puts a text file in his startup folder. The file says, "Your computer has been infected by the Snood virus!"

For context, Snood was a free video game people downloaded in the early aughts. Basically the same as Bust-A-Move, which probably doesn't clarify anything if you didn't already know what Snood is.

Anyway: "Your computer has been infected by the Snood virus! If you don't score [extremely difficult but not completely unrealistic high score] points, all of your files will be deleted!"

He laughed to himself and promptly forgot about it.

Weeks later, the roommate is on his computer in the middle of the night.

"What are you doing up? Go to bed."

"I can't. It's this stupid Snood virus."

I remember a more modern iteration of a virus that forces you to play an extremely hard game:

https://www.bleepingcomputer.com/news/security/rensenware-will-only-decrypt-files-if-victim-scores-2-billion-in-th12-game/

It demands a score of 200 million points in one of the hardest installments of Touhou on the highest difficulty. And 200M is pretty high, basically you need to finish all 6 stages and score reasonably well.

Autohotkey script that shuts the system down whenever someone types out certain key words. They of course include words related to looking up the issue like "help", "randomly", "virus" and so on. Not the most sophisticated but one I've actually done before.

Edit: Forgot to mention that ahk needs to be installed and the script must be placed in the autostart folder. Both can be achieved on a coworker's or family member's machine with a ducky usb stick.

[–] [email protected] 13 points 1 week ago (1 children)

Oooh, that's evil. You don't even need administrator privileges for that IIRC.

[–] [email protected] 10 points 1 week ago (1 children)

As long as ahk can be installed and the autostart folder isn't locked it will work

Change the start menu search so instead of finding local applications and files, it searches the internet.
Would be even funnier if it used the worst search engine available.
Oh wait...

In the early 90s there was a virus going around that made the floppy drive's loading noises play the Imperial March.

Simple, every now and again switch a key input with a neighboring key. Imagine slowly losing your confidence in your motor skills as you just can't seem to type properly no matter how careful you are.

It would do it like once every 10-1000 minutes, you will never catch it and slowly lose your grip on reality.

used to be fun at the office to take a screenshot of someone desktop, and make it the desktop background, then put all their icons into one folder.

[–] [email protected] 11 points 1 week ago* (last edited 1 week ago) (2 children)
  • Screenshot of desktop
  • Flip 180°
  • Set as desktop background
  • Right-click desktop -> Hide Desktop Icons

Edit: Markdown is dumb

Edit 2: Oh and hide the taskbar too

I used to make a batch file that opened a command prompt that opened the batch file again and again and put it on the computers as the internet Explorer logo.

People would get so mad when they opened it as a cascade of cmd would open until the computer crashed

So something like that i think

On somethingawful back in the day if you were on any one page on their forums for more then about 20 minutes, a audio clip would play that said something like "HEY EVERYBODY I'M LOOKING AT GAY PORNO"

I don’t remember the details but my mom’s first cousin called me once to fix her computer when I was a teenager.

No matter what she typed it came out as, “I AM FUCKING GAY!”

Seems like all I had to do was type “stop”.

[–] [email protected] 15 points 1 week ago (1 children)

Uhh, it was "Hey everybody, I'm looking at gay porno!" and then it proceeded to spawn hundreds of internet exploder windows pointing at goatse.cx. Thank God I was at home, alone, when it got me.

Supposedly there was a DOS virus that would spawn a pacman that would eat your letters as you typed them.

[–] [email protected] 14 points 1 week ago

The version I recall was once if those Flash animations with a cute squirrel or whatever saying something... but it was really quiet so you'd need to turn up the volume to hear. Then partway through it changed to sex stuff and blasted out in a voice like a monster truck announcer

"anal sex dot com, all anal, all the time!"

[–] [email protected] 13 points 1 week ago (1 children)

I have made some silly programs. One that moved the mouse pointer one pixel left, then down, right and up. It was quite annoying. Another that moved the mouse pointer when you reached the edge of the screen, touching the rightmost pixel row would move it to the left side of the screen and vice versa, same thing with top and bottom.

[–] [email protected] 10 points 1 week ago

You basically invented the endless desktop functionality, lol

[–] [email protected] 13 points 1 week ago

In my highschool programming class we made a TSR (in Borland pascal) that would change every 15th keypress to an "e". It wasn't self propagating, so it wasn't a virus per day, but it was highly annoying. It survived on memory after the netware logoff, and you could only get rid of it by rebooting.

We also had these everex brand 286 or 386 computers.... They had a little LCD screen that would read out what sector/track was being read on the disk. We found the memory address (80h) where we could write arbitrary text to the LCD. That was fun.

[–] [email protected] 12 points 1 week ago

How about a programm which screams "aaaaaaa" after you unlock your screen. Barely hearable at first and it gets louder with every minute. People who don't know how to remove it would have to lock and unlock their screens every 5 minutes or so.

[–] [email protected] 9 points 1 week ago

While the computer is on, at random intervals, it shall play the sound of a smoke alarm's low battery beep using audio technology to make it sound like it's coming from somewhere else in your house.
