Services will stay yellow for at least two hours. YELLOW : Once they are exploited, we will move them to yellow.GREEN : They begin their life as green, unexploited services.Some will instead go through the system of prior year, where services progressed through a simple lifecycle, which is shown on the scoreboard. This year, most services will have pre-committed flag limits. Last year, A/D challenges were be immediately retired when any single team stole 600 flags on the service. This is all only accessible through the VPN connection. Your own team interface (for service info, flag submission, tickets, etc) is at 10.13.37.Y:80, where Y is YOUR team ID. To attempt a King of the Hill, connect to 10.13.37.Y:Z, where Y is YOUR team ID. Once you have access to your jumpbox, to attack a team’s Attack/Defense service on port Z, connect to 10.13.37.X:Z, where X is the victim team ID. King of the Hill is different: you compete against other teams for the best solution, which depends on the service in question. The former format is familiar from decades of DEF CON CTF: you exploit other teams’ services to steal their flags, and protect your own. The Order has prepared two types of services for your enjoyment: Attack/Defense and King of the Hill. We would love to see all of you, but it’s still a crazy time around the world, so we’ll accommodate those that can’t (or don’t feel comfortable) making the trip.įrom our qualification round and the pre-qualifiers events, these 16 teams emerged as DEF CON 29 CTF finalists: We’re taking pains to make sure that teams on-site have no advantage over online teams. Players are welcome to join (part of) the Order in Vegas, but the infrastructure and challenges will live 100% on the internet.

Game Data Photos and source code courtesy of Joe Grand and Jeff Moss.DEF CON CTF 2021 ran Friday August 6 th through Sunday 8 th ( CTFTime) and were hybrid, like the rest of DEF CON. But if you must know, you can download this exclusive early release of the Defcon 17 badge source code. What the badges actually do with their components is a closely-guarded secret, pending a Friday presentation. This year there are different badges for each type of attendee: human, press, goon (the volunteers who staff the con), vendor, speaker, contest and über. Grand worked with Moss and "Black Beetle", the person behind the design aesthetic, to create custom circuit boards especially crafted for hacking. Hacking the badges to add interesting functionality is one of the many contests at Defcon that offer attendees a shot at winning the "Über Badge" - which gives them free access to Defcon for life. "Making the badge hackable is an important aspect of the badge, but we didn't want to make it as easy as last year." "Each year we try to show off cool new technologies and interesting circuit design features that have never been done before," he explains. The new badges are both simpler in design, and more difficult to hack, than in years past, says Grand, an electrical engineer, TV personality and founding member of the L0pht hacker collective.
