Top 1: DEF CON Finals Spot + Personalized Certificates + Awesome T-Shirts

Top 2: Internet Fame level Silver + Personalized Certificates + Awesome T-Shirts

Top 3: Internet Fame level Bronze + Personalized Certificates + Awesome T-Shirts

  • The personalized certificates are just like "medals" from the event, something that you will use to testify your participation and Top 3 in this hardcore competition.


* The certificates will be made at least two weeks after the event and only to members of winning teams;


Let's start with the rules - specifically what you and your team CANNOT do. :)

1 - It's strictly forbidden to perform any kind of Denial of Service Attack (DoS/DDoS) against the servers or the competition's infrastructure;

2 - Do NOT try to use Brute Force on the flag submission system because the flags are not possible to guess;

3 - Do NOT try to exchange flags or write-ups during the competition;

4 - Do NOT share recent discoveries related to challenges publicly on Discord channels, nor in any other way with contestants of other teams;

5 - It's not allowed to switch from one team to another team during the competition.

Ok, and now, for the more informative rules...

6 - Our official communication channel is on Discord, and it's essential that all players stay there during the competition in case there are important announcements.

7 - The teams may have as many members as they want;

8 - The flag pattern will be as follows: CTF-BR{something_here};

9 - The competition will last for 48 hours in a row, no breaks;

10 - Any kind of violation of these rules will mean immediate disqualification of the team;

11 - Most important rule: Have fun and Learn a lot! :)


Our judges will be the Admins on Discord. Any questions, talk to them.

Like we have done since the second edition, we'll do a Thematic CTF. Every challenge context will revolve around a fictional story. Also, the Jeopardy challenges will revolve around various categories (including subjects like Hardware Hacking). We chose to use a dynamic scoreboard system, where all challenges start with 500 points, and according to the amount of solves, the score decreases.


The winner team will be the one which score the largest within the 48 hours. In the case of a tie, the team that got to their score first will be crowned winner.
