Infos:

• We will primarily use Discord for communication (join the server at https://discord.gg/ASYqv7N2Rj ).
• The flag format is haix{.*}, unless specified otherwise in the challenge description.
• We use dynamic scoring. Challenges that are solved more often will be worth fewer points. Every team that solves a challenge is awarded the same amount of points, and scores will be updated dynamically.

Rules:

• A player MUST only participate in one team.
• A team MAY have as many members as they want.
• A team MUST NOT have organizers as members.
• If you have a question or a problem, you SHOULD reach out to us (e.g., if a seemingly valid flag gets rejected).
• Teams MUST NOT share flags or solutions with other teams.
• Teams MUST NOT use brute force to solve challenges unless explicitly allowed in the challenge description.
• The contest infrastructure as well as the infrastructure of other participants MUST NOT be attacked. You MAY only attack the servers mentioned in challenge descriptions or resources.
• If you find an issue with the infrastructure (e.g., a challenge is down), please report it to us.

Prizes:

• The top 3 teams will win 1x Binary Ninja Personal license.
