dJulkalendern yearly CTF challenge coming soon

dJulkalendern is an advent calendar where every window is a challenge. Do you like solving clever riddles, show your hacking skills, or how good you are at math? Be sure to compete for the title "Bäst på att Data" ("Best of Computering") and other, less fine prices.

This annual tradition begins as usual on the 1st of December, but you can already go to djul.datasektionen.se and log in with GitHub to make sure everything works and see the movie.

Good luck!
