❄️ The Rules ❄️

  1. Eligibility: Due to compliance with U.S. sanctions, we cannot accept registrations from individuals or teams who are citizens of, residents of, or have formal affiliations with sanctioned countries, which include, but are not limited to, Afghanistan, the Balkans, Belarus, Burma, the Central African Republic, China, Congo, Cuba, Ethiopia, Iran, Iraq, Lebanon, Libya, Mali, Nicaragua, North Korea, Russia, Somalia, Sudan, South Sudan, Syria, certain regions of Ukraine, Venezuela, Yemen, and Zimbabwe; are named on any U.S. sanction lists, or whose affiliated organizations are on such lists, including having representatives on business boards or in executive leadership who are on sanctions lists or located in the countries listed above. By registering, you confirm that you are not on any U.S. sanction list, your affiliated businesses are not on any U.S. sanction lists, and you do not have formal ties to sanctioned entities or individuals in the listed countries. We reserve the right to accept or reject any registration at our discretion.
  2. Feel free to utilize any resources within the limitations outlined here at your convenience to tackle the challenges presented. We particularly recommend utilizing accessible and community-supported, open-source tools. Don't hesitate to seek assistance online like Google. :)
  3. Throughout the competition, each participant is allowed to join only one team, and support for challenges must come solely from team members. Avoid sharing flags, solutions to challenges, tips, hints, or any information who is not part of your team until the CTF concludes.
  4. Each team may consist of up to four players.
  5. Do not share flags or hints. Avoid asking for or accepting advice from anyone except through authorized help resources. Tools like ChatGPT for assistance are permitted.
  6. Do not attempt to compromise or disrupt any teams and servers not specifically designated for hacking within the challenges. Additionally we advise against utilizing online brute force attacks on our systems, as this approach will not yield beneficial results. Should you have any uncertainities regarding what actions are permissible, please feel free to reach out for clarification.
  7. We ask that you do not utilize brute force methods to solve the flags. While we encourage with different flags if there is uncertainty, we ask that you avoid brute force techniques on our scoreboard. If you encounter a situation where you believe a flag should be accepted but it is not functioning as expected, please do not hesitate to contact us through the Discord ticket channel. We will be more than happy to help you.
  8. The flag format is atcctf_text.
  9. Have Fun! This CTF is about learning and growing.
