Another story on the spirit of wk93. TL;DR I DOS'd the whole campus network for some beers.

In highschool teachers had this blackboard system (a sort of moodle) and we used to have really lazy teachers who only read the PowerPoint presentations and made us take notes. One day I was fed up with their bullshit and figured these lazy ass professors wouldn't "teach" crap as soon as there was no internet connection...so the race was on...

10 minutes before the bell rang a friend and I managed to break in into a computer lab, I booted up Kali and searched for the access points, 3 routers through the building all with CISCO OS.

I figured they had all the default configs, time was running out so I decided to Smurf the three access points with the lab's IP range, scheduled an automatic shutdown in 2 hours and blocked the PC. The bell rang and as predicted, no internet, no class, my friends and I used that free time to go to a bar (on a Monday afternoon).

Funny side note, since the 3 routers were down the whole network collapsed, no cameras, no access control, no faculty network or any network. We kept doing it and every time we did campus security would be desperately searching for someone with a black hoodie.
