This year the challenge will be bigger, but space will still be limited. You can view the forum threads HERE.
ctf Capture the Flag:The qualification round for this years CTF is complete. More than 150 teams were actually submitting answers which means that participation for this year was more than double the previous high water mark (as far as we're aware). Results may be found at as always.

This years challenges came in a wide range of technologies and difficulties. No single team actually solved them all... Additionally, this years level of international participation was staggering...

The MUD for this year will remain up for teams to ask questions and hopefullly collaborate with each other about how they came to solutions for some of the harder challenges. Additionally, we will be putting most if not all of the challenges back online for a while so everybody can sharpen up... Stay tuned...

Not to be confused with the original Capture the Flag (CTF), aCTF is organized by DC949/Orange County for amateurs. Registration is now Closed.

We created the accounts for the Local Exploits box and e-mailed the account info out to all the registered teams. We're now closing registration. If you want to play but haven't registered, check with at con. As long as things are going smoothly, we'll continue to give out accounts at con after the contest has started, so don't worry if you didn't register... you'll still be able to play.

TCP/IP Drinking Game: Javaman - Adam O'Donnell will be guest hosting the TCP/IP drinking game this year.

When mudge found out that he wasn't going to make it to DefCon this year (something about getting married, going on a honeymoon, and buying a house - come on where are his priorities?!?!) he made a call out to his brethren in the Cult of the Dead Cow.

Low and behold - the call was answered and the TCP/IP drinking game will continue this year with mudge returning next year with a special guest line-up for the game (although have no doubt that this year's will be fine!).
New this year: Øwn the box? Own the box!
Are you a defensive ninja? Are your services unbreakable, your builds airtight? Do your countermeasures have countermeasures for counter-countermeasures?

So prove it, bucko... Bet your box on it, on the most hostile network in the world. Bring a laptop/server/desktop, hardened to the nines, running exactly two (2) visible services, to our specs, and we'll offer you up for the slaughter.

The first person to take you down walks away with your gear. When you're øwned, you're owned. It's that simple.

The last box(en) standing, unowned, wins, and the winner(s) can take his/her precious back home, safe in the knowledge that if it survived at DC, it can survive anywhere. Plus, get some way cool prizes. We haven't figured out what just yet. But they'll be way cool. We promise. We're thinking t-shirts with "Nobody Øwned me at DC15" would be a source of much pride, no?

For the other side of the fence, the reward is clear... Pick your target, bring your best sploits, 0wn the box, and own the box. A shopping spree for the elite.
