Back in 2005, my neighbors left their Wi-Fi unlocked, and they left their Photos folder set to "Public" on the network... So I stole all their pics onto my PC, deleted them from their PC, and burned them to a DVD-R disc. I left the disc on their porch, and on the disc written in Sharpie pen I wrote: "Secure your network. This could have ended up in the wrong hands." The next day, it was locked and renamed from the default. I got to be an edgelord while also being the good guy and teaching them a valuable lesson in security.

I literally deleted the Window XP server that my school was using because the "IT expert" of the school told me that Windows was better than Linux.

Back in the 90s... Had a chain of TV rental shops called Radio Rentals. Sold / Rented TVs, VCRs etc... All nicely on display in the shop window, demoing & playing whatever twas on TV at the time...

Please welcome to the stage... Casio watch with universal IR remote control... Turn all the TV`s up full blast... Watch the staff scrambling to look for remotes to turn them down. Guess you had to be there

Wow, a lot of bad people here damn. Spread joy and kindness kids, it's better.

Heh...I was about to reply on this topic, and then saw that I had already posted it two years ago.

Nice necrobump, @Jayro .This is certainly a fun thread to read.

My recent apartment sharers who just got kicked out, were absolutely dirty pigs who couldn't clean after themselves in any fashion. So I logged into the router, changed a bunch of passwords, and waited until I had all their device mac addresses. Finally, once I had their mac addresses, I made those mac addresses caped to 0.5 Mbps.

The total internet speed of our internet is 100 Megs a second. So i had super fast speeds to myself.

Was even funnier when they'd have friends over and I'd slow them down too. Dumb kids just never thought of changing to 4g.

I set Microsoft Edge browser as the default internet browser on a friend's PC.

Most of those aren't exactly destructive and weren't made out of spite like some others in this thread (instead I just wanted to have a laugh with my old classmates) but I've done my fair share of evil-ish things at my old school years ago:

1. I once made a clone of the Hydra "virus" from windows93 and let it autostart on one of the school's computer lab PCs. If you aren't familiar with what I'm talking about, it's essentially a fork bomb: it shows a popup and if you close it, two more identical ones will show up ("Cut off a head, two more will take its place"). I gave it a slightly different spin, however: first off each popup would spawn its own process and secondly each process would check the number of popups onscreen so that if even one would get forcefully killed by task manager, it would still register as being closed to the others (and spawn a lot more popups than normal as every running process would get that as I didn't write individual checks, this whole thing was hastily made in a few minutes). Of course you could still get rid of everything using CMD and TASKKILL but it would still cause enough annoyance to anyone who isn't too much tech-versed.
2. Some time later I made another script on a different PC that would wait a (long) random amount of time and either open or close the DVD tray and I also set it to start only after a couple of days to make it stealthier. I then disguised it as Adobe Reader's update service as it was the least likely to raise suspicions, including the right icon and metadata, then swapped the real one with my script. I then left it there and sure enough, even weeks after the script started to run properly, the PC was still opening and closing the tray at random due to it.
3. Way back when the iPod Touch was all the rage and jailbreaks were still relatively new, a classmate had jailbroken his own and installed a few default packages, with OpenSSH being one of them. If you don't know all iDevices have the same default root password, which normally isn't an issue as the root account is locked tight in iOS and you shouldn't be allowed to log into it - SSH or not - but it becomes a huge one if you jailbreak then install OpenSSH without changing it. So I decided to install Prompt on mine (a SSH client for iOS) and have some fun, either by making some stuff temporarily disappear without him knowing it, usually pictures or songs, or killing Springboard whenever I felt particularly evil (this was before iOS had multitasking, meaning the running app would also be closed). There's a happy ending to this story, however: after a while I told him the trick and explained that it was something pretty dangerous as whatever I was doing was way less scary than what somebody else could've done, so I helped him change the password and ensure others wouldn't be able to take advantage of this issue.

You had one of those?
90s me is jealous.
I had a remote the same as the ones at school* (and this was at a point where you could not just hit channel up/power to get it off standby, and of course nobody kept a remote with it) but the watch was the dream. Best one for that though was not me. There was this really annoying kid and the people in another class started a rumour that he had such a watch. My remote got borrowed to have some fun and the class started telling him to pack it in. Teachers believed the class, this despite no watch or one being seen stuffed in a bag or anything, and the annoying guy got in trouble despite this being one of the few times he was not responsible.

*I think cash converters was surprised to see an 11 year old so excited to get a TV/VCR remote, one they probably never expected to sell.

Back on topic I am not sure that I have ever done anything especially evil, grey hat or similar. I covered a previous time where I messed with a logo.sys of a computer and saw it get fully restored from image (though it would have still been called ghosted at this point) but that is business as usual really, even more so installing games.

I "stole" a nintendo switch motherboard and i put it on my switch to unban it.
Stole: a guy told me to hack his switch, and i saw the opportunity and he told me he didnt care for the ban and bam, unbanned.

Last year a friend and I cracked the password of a teacher on our school's website and saw all homework and tests of the year

We also changed the pfp of one classmate to an ahegao pic of Pepe the frog

When I was in college the first time, I wrote a "virus" by literally copying and pasting code from MSDN. Our class was doing a project in VB and we were told to look at MSDN for examples. The installer example had a bunch of code for modifying the registry (W98 was current at the time), and unmodified would just start deleting entries.

I disguised it as an earnings calculator for one of the popular "Pay per click" sites at the time, and had a quiet laugh as one of my classmates ran it. It completely scrubbed the windows registry until it was empty. I had to teach him how to restore from a registry backup.

I also stole my teacher's password with a keylogger, and saw the ENTIRE database of the high school

Some pranks I pulled on my parents:
1) Making them think their computer was failing via the click of death
2) Making their Echo Dots play some music (they hate)
and probably worst of all:
3) Making their computer play Frozen every time it booted

Our method was forcing him to login via HTTP instead of HTTPS and using ettercap to see the password

Lol, smart idea. I used a rubber duckyy to automatically download an email powershell keylogger

Not evil, just petty.

Not gonna lie, Jayro is kind of winning here. I know it's not a competition, but some of these are low effort trolling I did in high school. :x

When smartphones had IR blasters (S4/HTC M8) I went to my newly opened Buffalo wild wings... Played with their TVs for a bit. Random channels and audio levels. Even turned them all off before I left.

Oof. Now THAT is evil.. :o

When I was in college I was friends with this guy lets call him Eric(Thats not his real name). I knew this guy from a school you go to get more credits after leaving highschool. So there was this other guy(Lets call him Jim) we both knew and I guess he was either in a hurry or tired because he forgot to log off of the computer. Well it was April fools day and Eric said oh look he forgot to log off. I was like lets look at his stuff. Then we looked at his work and random stuff he had and decided to take all of it and put it into folders. So everything was put into a folder within a folder so it was a folder ception. I think some of the contents got corrupted since he was impatient with copying and pasting things. Jim came back after class and was like who f**ed up my work. He was vivid. He also discovered the computer he left logged in. I remember Eric was getting food to eat and was not in the room when it happened. He so scary and mad so I had to tell him Eric did it. Jim ended up making Eric help him with the work that was lost. I was innocent bystander and watched the whole thing unfold. It was a terrible thing to watch and I kept laughing like the idiot that I was. They were both engineers so the work they had was pretty hard.

Not sure if this is evil, but I had a special app on my Laptop and iPad Mini that effectively blocks people from accessing the internet. I would use it when my sister would get mad at her Splatoon game or when she would try uploading stuff on our 20 kilobyte upload speed WiFi.

I don't use them unless I need to access something nowadays though.

I also attempted to use said app to detect all of the devices on my old school's WiFi. The list showed thousands of devices. I didn't mess with any though since it probably would have caused my device to crash or overheat.

1) I set my router to throttle all the bandwidth for my brother's Xbox One, as he was using all the bandwidth to play Destiny, killing it for the rest of us, not to mention using more than 50% of the bandwidth we get a month. We live out in the middle of nowhere so we pay a lot just to get good high speed internet.
2) Inversely, I've configured my router to give my devices unlimited/priority bandwidth for the entire network. It's good to be in power.
3) Nothing else yet. But I'm always plotting world domination. Stay tuned.

Which router or model allows you to do something like that? I usually hear of modems that throttle devices, not actually give priority to specific devices.
