saintmehMay 16, 2020, 8:31 a.m.

yes... it takes a very long time. what the hell? It should mine some bitcoin while it's at it.


xiaoez123May 17, 2020, 9:36 a.m.

I have already register。But I don't know how to go and solve problem.


hxpMay 19, 2020, 4:14 p.m.

First of all, thanks to the Order of the Overflow for organizing another edition of the CTF! We know it's a lot of work and we appreciate the effort.

While in the grand scheme of things this certainly qualifies as a good CTF, we unfortunately don't think this year's DEFCON Quals have lived up to the high expectations associated with commonly being considered the "world championship of CTFs". Here's some hopefully constructive criticism:

* So many updates! Lots of challenges had to be changed soon after their initial deployment because some problem was found, and rumor has it that this was not always publicly announced. This suggests a lack of uniform infrastructure and internal testing.

* Many unintended solutions, some of them devastating (i.e., making the challenge much easier). This again suggests insufficient internal testing. [NB: unintended solves are not necessarily a bad thing per se, this is a hacking competition after all, but it is kind of sad when it spoils the entire point of a challenge...]

* A few words on challenge design: Of course this is a matter of taste, but several challenges included reversing compiled binaries as a first step for no reason whatsoever (e.g. coooppersmith, keml). Sure, this can be considered "realistic", but reversing the 1000th x86 ELF in your life just eats up a lot of time while not really being fun or interesting or educational. Some of our members were under the impression that some challenges, or parts of challenges, felt a bit uninspired and existed simply to slow down participants on their Quest To Capture All The Flags, rather than to showcase fun/weird/broken aspects of the state of computing.
Beyond that, there were quite a few challenges that gave big teams a significant advantage: For instance, for the golf challenges it was certainly beneficial to have many people working on different approaches resp. subsets of binaries in parallel. It seems that this CTF favoured teams with many good hackers over teams with fewer, but perhaps even better hackers.
Finally, on the "floood" challenge in particular, the only solve was essentially an accident and not even the person who did it understands why they got the flag. This is obviously guessy/random and not worthy of a CTF striving for excellence.

* Web tasks with unstable hosting and without source are a very bad combination: There's little point in fuzzing the server for interesting behaviour (or, worse, having to port scan a full network one HTTP request at a time) when there are random errors all the time anyway — that is, assuming the server/admin bot/... is not completely overloaded and you get a response at all.

* There were at least three distinct proof-of-work variants (sha256 in pow.py, sha512 in the mazes, blake2b in *ursed), again suggesting a lack of uniform infrastructure and essentially wasting (a little bit of) everyone's time on adapting PoW solvers instead of focusing on the actual challenge.

* Releasing challenges shortly before the end penalizes people who happen to live in the wrong time zone (e.g., in this case, teams from Asia).

* The game chat was hosted on Discord, where we need to register and wait 10 minutes before posting. Discord doesn't like disposable email addresses and asks for a phone number when they catch you using one. Forcing this upon participants of a renowned CTF is ridiculous and the organizers should know better (i.e., use IRC).

We emphasize that despite these points of criticism, the CTF was still a great one in the most important sense — we definitely had fun. Nevertheless, it would be nice if a CTF that is considered the ultimate benchmark by some had fewer of the issues above.

I personally think using anything other than IRC is a major improvement. It's so nice being able to scroll back and see chat history. And making people use a real email is not ridiculous.
I agree with most of the challenge related criticism though (PoW and not enough testing)

I neither played this year nor was an organizer (was occupied with HackASat) so I can't speak to any of the challenges but I do have some insight into discord -- I believe that requirement was leveraged on OOO by DefCon proper. They were very firm that they wanted all events to be using their discord so it's not really within the control of OOO.

That said, even if it was I don't think it's a massive hurdle to hop. Now, a better bit of constructive criticism might have been whether all announcements went out over all communication channels which is something I think should be mentioned so other CTFs can learn from.

Make sure you have a defined set of channels (preferably multiple!) for announcements such as new challenges or updates to challenges. Twitter, Discord, Irc, posting to a weblog. The more the merrier as long as you're using automation to post to all of them simultaneously!
