Will the rating be changed? Almost every team brought 2 (mostly really hard) challenges (there were 20 challenges in general).

So scoring points was not easy, also every team had to present their own challenges and the solution for them (it gave the 30% of the total score).

The prize for the 1st place was $50000, $30k for the 2nd and $20k for the 3rd.

So it was one of the most hardest CTF of the year so far, I think it should worth some weight...

@ktx but it was a closed, invite-only (!) event, and from what I remember those were never scored. It would simply be unfair to the teams that did not get invited.

This could very easily be abused by organizing an event and inviting only the teams you want to boost in the rankings. Despite the outcome, all of them would get points no-one else could get. In fact you wouldn't event have to make the event - you could just pretend that the event took place. Because of that I believe closed events like this one should always have 0 rank, unless there are open qualifications.

AFAIK they invited the TOP teams from CTFtime (2015 rankings). It's like a 1-year qualification round :)


Pharisaeus – June 10, 2016, 10:04 a.m.

@ktx judging by 2015 ranking they invited teams: 2, 3, 5, 6, 8, 13, 14, 26, 36 and (1+22). Not to mention it's unfair to inform about such qualifications after they took place ;)

Some teams missed the deadlines, like Shellphish (#4); 217 (#9) and HITCON (#13) are playing together in bigger events; PPP (#1) wanted to decline the event as there were not enough team member who could go, but in the end they united with DEFKOR. GoN is probably an exception, but sometimes team get invited because they won some local CTF.

By this logic why CSAW Final has weight? Only Canada + US teams can participate: https://ctftime.org/event/271

Also in my opinion CTFtime scoring is starting to favor quantity before quality. It becomes a big race of who can build bigger teams, upvote medium difficulty CTFs and downvote hard ones. (Which is understandable as these are the rules now, but in the long run I don't think it is the right direction...)


Pharisaeus – June 14, 2016, 11:45 a.m.

I have no idea why CSAW finals have some weight. If it's closed for very specific group then I would expect it to have 0 (like Volga Finals last year - https://ctftime.org/event/232 ). But this is a question for CTFtime admins.

CTFtime seems to have always favoured quantity, it's just lately there are a lot more easy and medium CTFs, so it's starting to show. If you don't play pretty much every week then you will quickly drop in the ranking, and playing only in the difficult CTFs is not enough anymore. Just look at LC↯BC - they play together only in the hard ones and they do really well, but sill they have little over half of dcua points.
As for the big teams - it might be because the CTFs are becoming harder and harder, since organizers want to provide "interesting tasks" and not repeat something that was already done. Because of this some hard tasks can take 30-40 hours.
