DEF CON 22 CTF Quals Roundup!

The DEF CON 22 CTF Qualifiers are in the books. Challenges were faced, and bested. Points were accumulated. Bedtimes were missed. It’s all over but the paperwork.

So here’s a roundup of writeup links. IF you participated, read and see how other people approached the same problems. If you didn’t, read and get an idea of how the CTF process works and consider signing up next time. You lose 100% of the CTFs you don’t enter.

If you enter, you could still lose 100%. That’s just math. But you’ll have a story. An awesome, glorious, highly technical story to share with the tiny slice of humanity who can understand this sort of thing.

There’s also a bonus link to a GitHub collection that looks like it might end up pretty comprehensive.

DEF CON 22 CTF: Registration is Open!

Good news, everyone!

Registration for the DEF CON 22 CTF season is open! To accomodate international competitors, the qualifying weekend has been moved to May 17-19.

It is time to assemble your champions. Sharpen them to a fine point. The doors to the arena open May 17. Fortune looks kindly upon boldness and skill. Failing those, she also seems pretty okay with treachery and subversion.

Step forward and meet your destiny.
