about & rules
01
Individual or team
Compete solo or form teams of up to 4. Each team registers under one shared account.
02
Honor system
Flags are static. Sharing them is detectable and will result in disqualification of all involved parties.
03
Infrastructure rules
Do not attack the CTF platform itself. Only challenge-scoped environments are in scope.
04
Dynamic scoring
Challenge points decrease as more teams solve them. First blood awards a bonus.
