During the CTF you use no AI tools. If you do, you are disqualified. It is about your skills, not a model's. If a normal search accidentally shows you an AI summary, such as the one above Google's results, that does not count as a violation. Only actively using AI is off limits.
Fuzzing and scanning tools such as nmap, ffuf and feroxbuster are not allowed. They are not needed and load the system for everyone. The only exception: if a challenge explicitly states it is allowed, you may use it for that challenge. Otherwise, do not use them.
There will be photos and filming. By being present you consent to this. Do not want to be on camera? Get a badge from the organisers and we keep you out of the shots.
A team has up to 4 players. You can also play solo. Win solo, and the cup and the whole prize are yours alone. No team? Pick 'Place me' when you sign up and we place you with other solo players.
You do not have to hack. There is food, snacks and free merch for everyone there, and you can walk around and meet people all day. Joining the CTF is entirely up to you.
