If you would like to do some CTF before or after this competition, we do host daily CTF challenges on our main website and Discord server. You can join the competition for practice, or just for fun, as we will continue hosting them throughout the year.
We also have an active community around our daily challenges to provide support and help! Our daily challenges use the same Discord server as the server for this event, so feel free to stick around after the competition.
