CTC 2020

Challenge the Cyber is a capture the flag event, where teams work on a number of challenging assignments together. To capture the flag, teams must solve several assignments (from easy to hard) in several categories. The challenges offer enough variety for both novice hackers and seasoned CTF players.

The CTF is developed on the basis of the ECSC curriculum.

The national Capture the Flag competition Challenge the Cyber ​​takes place on Saturday 27 June 2020 at a central location in the Netherlands. There is room for a maximum of 200 participants.

There are two competitions this year: for junior teams (birth year 2000-2006) and for senior teams (birth year 1995-1999). Teams consist of a maximum of 5 participants.

Contrary to what was previously stated on this website, we have loosened the rules for the categories:

1) Teams of which all team members have birth year 2000-2006 participate in the junior category;
2) Teams of which all team members have birth year 1995-2006 (teams with juniors and seniors, or only seniors), participate in the senior category;
3) Teams that have one or more team members with birth year 1990-1994 participate in the outside category.

Only members of teams under 1) and 2) can qualify for the talent class. NB: judging by the age composition in 2019, the junior category may be less heavily occupied. Juniors who play in this category are more likely to win a place in the talent class.

No team? Individual registration is also possible: the organization will then put together a team.

Older than 25? Challenge the Cyber ​​is primarily aimed at young talent, who can qualify for the talent class. For those born between 1990 and1994, there is a possibility to participate in an outside category.
