[+] Use common sense. If you feel that your actions are disrupting the competition in any way, please stop immediately. Don't wait for us to reprimand you.
[+] Do not post flags or solutions to challenges in public places before the CTF has ended. This will spoil the fun for everyone else. Solutions and write-ups will be posted at the end, and we welcome submissions from participants.
[+] Do not attempt to attack other participants.
[+] Do not attack the scoreboard infrastructure. Specifically, do not attack the domains or https://ccsc.cybermouflons.com/ or https://ccsc.org.cy/.
[+] Do not engage in Denial-of-Service attacks.
[+] Do not engage in brute-force attacks.
[+] Any kind of challenge discussion or questions should be directed to one of the mentors/challenge authors within this server. It is prohibited to discuss challenges outside of this server.
[+] Be respectful. Refrain from using profanity, spamming, or harassing others. Do not discriminate based on age, race, gender, religion, nationality, ethnicity, sexual orientation, choice of Linux distribution, or any other factor.
[+] The flag format is ECSC{...}, unless stated otherwise.
[+] Breaking any of these rules may result in disqualification. Decisions made by the competition organizers are final.
[+] The competition is open to everyone but eligibility for ECSC national team is only constrained to Cypriot nationals born between 2000 and 2011 (inclusive), within the age range of 14-25.
[+] Selection for ECSC Team Cyprus will be based on CTF performance plus an interview after the CTF. A high score alone does not guarantee a spot in the team.
