See if you can help these poor student hackers regain control over their site by getting some oooverflows: ooo.asuhacking.club
ASU Hacking Club@asuhackingclub1 Apr 2022
ATTENTION ALL HACKERS: send help! Our site has been taken over by the @oooverflow for hacking tax evasion! We swear we paid our taxes! Our old site asuhacking.club now completely redirects to ooo.asuhacking.club. Overflow the service to help us reclaim our site!

It may have started as a joke, but we have control over the site, and they won’t get it back until we get 20 oooverflows

As ex-CTF organizers we must now find a place in the hacking scene. Starting in one week’s time, we will begin to investigate CTF groups to determine if they have paid the proper hacking tax. No free bugs indeed.

😀 I am starting a fundraise for @picoctf. PicoCTF is free to everyone, and costs about $500k a year (🙀) to run. If you've had a positive experience with pico, please reply or DM. I'll use it in my fundraise pitch. Pls RT for awareness. #ctf #hacking

Very happy to finally release the game code that @oooverflow used to run @defcon Finals CTF 🎉 This was roughly the 3rd attack-defense CTF game infrastructure that I've written, so there's a lot of design principles and lessons learned that I'll share here in this 🧵 ...
