RuCTFE 2020 is over? Not yet!
Despite the ending of the A/D game, we have one more thing for you.

This year we did not have the opportunity to conduct RuCTF which is not only A/D but also the conference. Coronavirus happened, borders closed, bringing people together turned out to be too unsafe. So we have decided to invite speakers to participate in a conference at the end of 2020 because you don't have to be somewhere physically to get some useful skills and experience. For our online RuCTFE conference, we have filmed speakers' talks and are going to post them one by one at the beginning of 2021.

Of course, we understand the importance of interaction. That's why you get to ask any questions to the speakers in YouTube premiere comments section and the speakers will surely answer you! Also, it's a perfect chance to chat with others like-minded without worrying about life safety.

Subscribe to our YouTube channel to stay tuned and don't miss the premiere!

And… repo is open! https://github.com/HackerDom/ructfe-2020
We would like to remind you about feedback, CTFTime voting and say thanks for the third time and wish you a Happy New Year!
Always yours, RuCTFE.org/devteam
