Event organizers
The HFCTF is only on premises at the Centre des Congrès de Québec, not online.
The CTF will last 24 hours non-stop for participants and will run from Thursday 19:30EST to Friday 19:30EST.
It's mandatory to purchase both a Hackfest Ticket and a HFCTF ticket to participate in the CTF (https://hackfest.ca/en/register).
You must join the official Hackfest Discord server in order to participate in the CTF (link: https://discord.hackfest.ca). On the day of the event, you'll need to sign in using your Discord account to access scoreboards and CTF infrastructure.
The HFCTF is a 24 hours team event, so only teams of six will be allowed. Contestants that are not in a team or that have a team with fewer than six members will be mixed randomly to create tables of six people. You can ask on the Hackfest Discord if you have any questions about this.
Teams are not managed in Eventbrite, so you can buy your tickets as you wish. Teams will be formed at the beginning of the event where you will create your team and declare a captain when you log in to the CTFd. More information will be given on the Discord.
Further details will also be on the Hackfest Discord. A dedicated channel for the HFCTF 2025 will be created with all the necessary information and support.
