Ask HN: Anyone Interested in Capture the Flag (CTF) Events?
I ran the DEF CON CTF from DEF CON 20 to DEF CON 25. Prior to that, I won a few.<p>I know order of the overflow is running a good game now. It’s different than what we did, but it’s a good direction, and I am hopeful it will continue to grow.<p>They (like we did) have a few selected prequalification events tbgat are generally pretty high quality. See <a href="https:&#x2F;&#x2F;www.oooverflow.io&#x2F;dc-ctf-2019-quals&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.oooverflow.io&#x2F;dc-ctf-2019-quals&#x2F;</a><p>PlaidCTF was an old favorite of ours as well. PPP has won several competitions, and seems to understand what makes a good challenge, what makes a challenge hard, and more importantly, what DOESNT make a good&#x2F;interesting challenge.<p>Boston Key Party also runs a pretty good game. But a lot of them became Order, so who knows what will happen with them...<p>DARPA ran a CTF for autonomous systems called the Cyber Grand Challenge. It was neat, but I don’t know of any plans to do anything like it again. I believe they’re waiting to see what the community does to push the state of the art further.  Source code for challenges and infrastructure are at <a href="https:&#x2F;&#x2F;github.com&#x2F;cybergrandchallenge" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;cybergrandchallenge</a>.  There’s also a bunch of video at the darpatv YouTube channel.<p>We open sourced most of our challenges&#x2F;frameworks after the fact. <a href="https:&#x2F;&#x2F;github.com&#x2F;legitbs" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;legitbs</a>. This includes the compiler&#x2F;emulator&#x2F;manual for our 9-bit bytes custom architecture, clemency.  That was probably our most ambitious year...<p>That’s all off the top of my head. If you care for more from a CTF has been, I’m happy to come back and answer more questions.
