The Advent of CTF
The Advent of CTF is a yearly CTF competition held in December.
It features 24 challenges that range from easy to hard.
The competition is created and curated by Arjen Wiersma. Most challenges are original works, some other challenges were based on challenges seen in other CTF challenges that highlighted extraordinary fun and challenging topics.
The first edition was in 2020. During December about 500 participants solved 24 web challenges. The top 20 finishers received a Challenge Coin and the top 3 received additional prices from Hack The Box.
