Welcome Legitmate Business Syndicate as the new DEF CON CTF Organizers!
Exciting news: we've decided on a schedule for the 2013 DEF CON CTF season! Join us this year as we host qualifications the weekend of June 15-17. Registration will open on May 1.
Changes for 2013
We have a new and exciting team size limitation for you! Should you qualify, your team in Vegas will be limited to eight: you won't be allowed more than eight seats at your table. Work with us on this :) If you've got friends dropping by with food/booze, that's cool. If you've got runners carrying flash drives back and forth between the competition area and the rest of the team holed up in hotel rooms, that's not. We're building fewer and harder challenges for the competition: parallelization will be of limited value, and a win with a small team is more elite anyways.
Web stuff won't just be simple baby's first SQLi this time. It'll be hard, it'll be related to real-world stuff, and we think you'll enjoy it.
We're dropping categories from previous years. You can leave your forensics tools at work, you're not going to be undeleting .TGA files from FAT12 dumps this year. You don't need to bookmark all those DEF CON history pages either, trivia is gone, and we promise to not make you answer "____ ___ ______!"
Not changed for 2013
Do go brush up on your assembly, and don't just stop at Intel/AMD's offerings. ARM processors are scary popular, PPC still exists lol, and who knows what other popular architectures might make a cameo. Expect to be taking over applications remotely, reverse engineering some ridiculous binaries, and writing mind bending shellcode.
More open and less ambiguous
We have a presence on the official DEF CON forums now. We won't monitor it 24/7, but as quals draws closer, we hope to answer some questions.
Additionally, you can follow @legitbs_ctf on Twitter; some of the individual businessmen have Twitter accounts too, and may (or may not) have relevant information.
