Important Notices

Flag format is CZ4067{flag} unless otherwise stated.

Players may make multiple attempts to solve challenges hosted on CTFd, but automated bruteforce attacks and DoS attempts are strictly prohibited. Refer to the notification page for allowed types of bruteforcing methods.

Challenges are hosted across two different domain names - check challenge descriptions for server details.

All challenges must be solved independently. No sharing of flags or solutions during the competition.

Pay attention to notifications.
