About

The mission of the Asian Cyber Security Challenge (ACSC) is to deepen the partnership between participants across the Asia and international borders to contribute to the global cybersecurity development.

The ACSC is the regional final of the International Cybersecurity Challenge (ICC) — a global CTF competition, supported by the European Union Agency for Cybersecurity (ENISA).

The ACSC is organised to identify talented CTF players to represent Asia to compete on the world stage at ICC.

The date of the ICC has been changed in consideration of the COVID-19 event.
The ICC will be held in Athens, Greece from June 14 to 17, 2022.

Greece is very beautiful in early summer.
Hopefully, by the time the ICC is held in June 2022, the COVID-19 situation will have improved and we will be able to go abroad and meet face to face with players from all over the world.

Rules / Prohibitions

Rules

  • This is an individual competition. As noted in prohibitions, by no means players are allowed to communicate and cooperate with each other.
  • The flag format is ACSC{something}, unless otherwise specified.
  • Players need to submit a flag to the score server in order to get points.
  • The scoring system is static. That means every problem has a predefined point value. Also, there are no breakthrough(first blood) points awarded to the first solvers.
  • A player that has more points, ranks higher. If some players have the same points, the player that has made the last submission of a valid flag earlier, ranks higher among them.
  • For verification, the organizers may ask the top players to submit a brief writeup after the contest is over.
  • If there arise situations which are not covered by these rules, the organizers may make decisions on them as needed. The decisions made are absolute.

Prohibitions

If you break the following prohibitions, you will be disqualified and banned.

  • Players must not share flags or solutions with each other.
  • Players must not attack/obstruct other players
  • Players must not attack the contest infrastracture other than the servers explicitly allowed to do so in problems. Also, players must not try brute-force attacks even to the allowed servers.

If you have a question, please contact us via Discord.

Selection of Candidates for ACSC Finalists Team

A player is eligible to be selected as one of the Asian representative players if and only if he or she meets the following conditions:

  • A player lives in the member countries of the ACSC committee.
  • A player has the nationality in the member countries.
  • A Player is under 26 years of age (25 years or younger as of January 1st, 2021 in “international age”. Born on or after 01.01.1995)

After the contest is over, the ACSC committee will select the fifteen Asian representative players according to the result of the contest and the following procedure:

  1. For each member country, the player from that country with the best score will be selected.
  2. If no “non-male” player is selected in 1., the two best “non-male” players will be selected.
  3. The remaining members of the representative players will be selected from players who have not yet been selected, in descending order of their scores. However, each member country has its own limit on the number of players from it to be selected, and if the limit is reached, no longer players from it will be selected. Here, “a player from some country” means a player who has the nationality of that country. The limits of member countries are the following:
    1. India: 3
    2. Japan: 3
    3. Malaysia: 1
    4. Singapore: 3
    5. South Korea: 3
    6. Taiwan: 3
    7. Thailand: 1
    8. Vietnam: 3

If a player who is to be selected is unable to participate in International Cybersecurity Challenge (ICC) for some reason, we will resume this procedure from the next player until we have fifteen selected players who can actually participate in ICC.
