https://everything2.com/title/Jordan+K.+Hubbard > Long before FreeBSD, Jordan K. Hubbard earned a spot in Internet history in 1987 when he accidentally attempted to broadcast an rwall message to every machine on the Internet. He stopped it once he realized what was happening, but not before he & the other UC Berkeley network administrators were flooded with complaints.

Got in trouble for something similar in middle school, actually. I would bike over to the high school for my robotics club, and some of the older members had written a privilege escalation script for the Windows machines. So, I brought it on a flash drive to my technology class the next day and ran 'shutdown -i' with admin privs. Being young and stupid, I broadcast a reboot message to all ~700 machines connected on t…

I played with network sniffer on home network (that sent funny packets to switch to make it MITM traffic thru my machine). Except it didn't work/I fucked something up and all traffic went thru my machine.

They couldn't prove it's me so teacher just blanked banned anyone in the library (our class with few of my friends were on the 4 machines in the library) from using machines there for few months.

Then when we got new shiny machines for computer lab I was bored when the teacher was explaining something so I started guessing admin password. It was zaqwsx

I put `net send * Seniors2005` 200 times in a OPEN_ME.bat file and put it in our shared folder on the school network (it was buried deep in the Art department directories and was full of emulators and music and stuff.

My friend saw it and said "What's this?" I told him not to open it and of course he did so immediately.

This was a K-12 school, so every single lab, every single teachers computer all the way down to kindergarten got it.

When IT came to my friends machine, I fessed up and got in trouble. Banned from school computers for the rest of the year, all my teachers got a notice about it and I had more than one awkward conversation about what I did.

Once upon a time we were pranking each other in the university lab. We thought ourselves pretty clever by convincing a friend to run a Fork Bomb.

"What is it supposed to do? Nothing's happening."

"Really? Did you run it in a shell?"

"Yeah, in my SSH session in the main server."

Oh.

The server was down for a couple of days while the admin figured out what happened, fixed it, and limited the number of open processes per user.

I too discovered the wild card net send in high school. I was at an assigned computer in class though and ended up with a stern talk from IT in which they claimed I caused all sorts of network issues. I thought it was hooey at the time but I was pretty sheepish about the whole thing.

I didn’t get in trouble and returned to class.

Later that year I installed VNC server on my friends workstation in the same class and used it to mess with him during class. We had a pretty good laugh. Another friend saw this happen, took the idea with some of his friends and a few days later installed VNC server on a bunch of computers throughout the building. My understanding is they generally caused a bunch of chaos, it was figured out who had done it, and the group were arrested(!). They ended up with community service if I recall.

I very thankfully was not pulled into this at all and found out about the whole thing later.

Oh man I remember doing the exact same thing in high school, didn't think the wildcard would actually work. Overheard concerned teachers talking about it and never fessed up until now!

Congrats on topping HN with your blog's first post, lol.

This is something I actually worry about future generations missing. My core love of computers came from being able to tamper with them. Being able to poke around in the operating system, figure out how to do neat things, etc.

Today, students are given either an iPad or a Chromebook, and generally locked into using some horrific privacy nightmare like Gmail, and have very little ability to actually experiment with computers.

I suppose this means we have better security, but people like me born more recently may not end up in the field because of it.

I was working a tech conference, probably around 2001, with about a hundred PCs networked together. A colleague of mine intended to send a simple "net send" message to only my workstation, just as a joke. He messed up the syntax and the popup appeared on every PC in the conference, including the giant screen in the main conference hall. The message: "Fuck you" . He was fired the next day. (Don't feel bad for the guy.…

Similar story; bet with a friend to hack and change his password at university. Accidentally changing all user passwords to some profanity including his name, luckily didn’t get caught.
