THE RULES

The competition starts on June 18th, 2021 at 1 PM CET. The password for the CTF image will be revealed on this Information page at 12:45 PM, and challenges will open at 1:00 PM CET. Do not miss it.
You will have 24 hours to solve 11 challenges covering this image, ranging in difficulty from 'Baby' to Hard. The game finishes June 19th, 2021 at 1:00 PM CET.
Dynamic scoring will be used: the more participants solve a challenge, the cheaper it will be for everyone who solved it. There is no speed bonus, points are decreased for everyone, including those who already solved the challenge. The winner is the one who scored more points than others did. If two competitors have the same amount of points, the one who reached that amount earlier, wins.
Unlike previous BelkaCTFs, there will be THREE separate winners: for students and for professionals, and additionally the champion by overall score for CTF #2 plus CTF #3.
Awards for all nominations: the winner gets a nice set of Belkasoft merchandise, first 3 places get winner certificates, and everyone else gets a certificate of participation. Overall winner will get a special prize!
