EasyCTF just concluded this Monday! Looking - back on the competition, I’d say that this year was our best year ever. Let’s take a look at some of the - stats.

-
    -
  • 5,837 users registered this year, playing on 2,742 teams. Of those teams, 1,938 teams scored points.
  • -
  • We had 63 challenges, which was close to our 68 last year. -
  • -
  • 10.7% of all teams had 5 members — full teams! In - fact, there were more 5-member teams than there were 4-, 3-, and 2-member teams.
  • -
-

I’m really happy to see that so many people - were willing to give us a week of their time to participate in our event and work through our challenges, - despite the fact that we hadn’t promised any prizes ahead of time.

-

I’d also like to give a shout-out to the entire - dev team who helped monitor basically every point of contact that people had with us and creating amazing - challenges.

-

Improvements for next year

-

I still haven’t decided whether I’ll be - completely involved in organizing this event again next year. I hope that I’ll have some free time - alongside my classes, but I’d also like some more cooperation from the rest of the organizers. The biggest - problem we had this year was basically not working on anything until the week before the competition. By - that time, it was already too late. Let’s take a closer look at what actually went wrong:

-
    -
  • Lack of motivation. I’m not sure people were - actually busy during the entire year that we had planned to work, but there was definitely a lack of - work put into organizing the competition. We had some big ideas at the beginning of the year, but as - time passed, the chances of those ideas becoming reality looked rather slim as no one wanted to be the - first one to start working. Somewhere in there I threw in a couple of deadlines, and we got a couple of - problems written. Had I not done that, I fear we would have had much fewer problems than we actually - did.
  • -
  • No contact with sponsor companies. Contacting - sponsors should have been one of the first things we did, since it takes a long time to sort out details - and companies usually take at least two weeks to reply to emails anyway. Towards the end, we did get an - email from DigitalOcean saying they were willing to fund servers for our competition, but launch day - came and we didn’t hear back from them again.
  • -
  • No coordination. Some of the feedback I’ve been - hearing about this year’s competition is a shortage of actually “easy” problems. We never really went - through the competition and tried to lay out a “spectrum” of problems nor tackle it from the - participants’ perspective. Every problem was either just a “cool idea” someone had or “I feel like a CTF - needs this.” The intermediate web section was completely missing.
  • -
  • Unbalanced team. Our team comprised mainly of - problem writers. That’s great and all, but when it comes to things like contacting sponsor companies, - writing the website, planning some kind of game, we basically have no resources to do those. I spent my - entire time developing OpenCTF, the platform that powered the competition, and I know for sure that was - a task too large for me to handle. Getting more web designers or people with other skills would have - helped out a lot.
  • -
-

I’ve also got a couple of points of reflection - for prospective CTF organizers, so if you’re planning to run a CTF, this is for you.

-
    -
  • Participant experience takes first priority. A lot - of organizers think the hardest part of running a CTF is getting good challenges. And they’d be right. - But that’s not to say that preparing a solid game infrastructure for flag submission is going to be - something you can do last-minute. When it comes to the participants’ experience, the first thing that - they encounter is the website. Then a few initial challenges. Then probably the chat. Make sure you have - those down well and people will probably have a better initial impression of your CTF.
  • -
  • Some people are there to make you miserable. As the - one in control, you need to account for those people. We’re lucky that we only had relatively few - encounters with such people but do keep in mind that you are still running an event and that takes first - priority. During EasyCTF, there were a couple of people who thought it was funny to drop flags for hard - challenges into the chat room. When we tried to get them to stop, they would come back under different - aliases in order to annoy us. At that point we just shut down the entire chat room; the competition had - to go on.
  • -
  • Ignore unconstructive negative feedback. You’re - always going to have haters. Don’t take it to heart, solve the problems, and move on. Who cares if some - random kid in IRC says your CTF is garbage? Ask them what issues they’re having, fix them, and they’ll - be happy. It’s really not that complicated.
  • -
  • Docker. Is probably a good idea. The learning curve - is not bad and it’s a great way to create disposable containers that can restart easily. Not only should - you use Docker for your main competition website, you should also use it for all of the challenges that - involve communicating with a server.
  • -
-

Here’s something else I definitely have to - share. We had this autogen system that created different flags for different teams in order to discourage - flag sharing. Some people came up to us reporting that their flag wasn’t working, when they clearly just - took some other team’s flag. I didn’t really do anything about it, but just thought it was pretty funny - that they had the nerve to report it to us even though they were cheating.

-

So, what’s the future for EasyCTF?

-
    -
  • I’m seeing OpenCTF as a more permanent - solution to our main platform. It’s a very complex piece of software and it would be insane to try to - rewrite it from scratch. I’m in the process of creating an open-source version of it and making it - customizable (for example, turning off features that you don’t need like the programming judge) for CTF - organizers.
  • -
  • We had this project going on a while back - for a CTF calendar that also hosted tasks. I was also hoping that it would be able to replay entire - competitions but that seems a bit too hopeful at this point. It would be nice to just get the calendar - revived.
  • -
  • WeebCTF is happening again this summer, - dates still yet to be decided. If you’re into anime (or even if you’re not), come check it out!
  • -
  • Applications for joining the organizing - team for the next EasyCTF will open soon. If there was something you didn’t like about EasyCTF, and you - think you could have done better, by all means, join the team! We’d like to hear your ideas.

Thanks for reading, and I hope - I’ll be seeing you at the next CTF!
