Le Tour Du Hack 2025 CTF Rules

General Conduct

• Play fair and have fun.
• Respect all participants, volunteers and organisers.
• No harassment, discrimination or exclusionary behaviour; we follow the Berlin Code of Conduct.
• Do not disrupt other teams’ work or the overall event atmosphere.

Technical Rules

• Do not attack or interfere with the CTFd platform, organisers’ infrastructure, or other teams’ systems.
• Do not share, forward or post any flags outside your own team.
• Do not launch denial-of-service or excessive enumeration tools (e.g. mass directory bruting).
• All flags must be submitted only through this site.

AI Usage

• You may use AI tools for research, learning and hints—but you must not submit AI-generated solutions verbatim.
• If we suspect submissions derived solely from AI outputs, you may face disqualification or further action.

Onsite & Physical Challenges

• Follow all instructions provided for physical or onsite tasks.
• Do not endanger yourself or others; comply with health, safety and venue regulations.
• Physical challenge flags must be collected in person and submitted via CTFd like digital flags.

Enforcement & Appeals

• Violations of any rule may result in point deductions, disqualification, or additional sanctions.
• The organisers’ decisions are final. If you believe an error has occurred, contact committee immediately for review.

If you have any issues or questions wave excessively at a committee member and they'll probably look confused but will eventually realise you need help.

Most important rule: Have fun!

By registering and participating, you agree to abide by these rules and the Berlin Code of Conduct.
