What is AI-Assisted CTF?

Solve Jeopardy-style CTF challenges across Web, Crypto, Reverse Engineering, Forensics, OSINT, Pwn, and Misc — but all solutions must come from guiding the provided LLM agent, not manual solving.

Scoring

Score is based on token efficiency. Each challenge has a token budget — use fewer tokens to rank higher. Up to 10 attempts per challenge; only the best counts. Ties broken by time.

Rules

  • Use only the official LLM agent — no external AI tools, scripts, or manual-only solutions.
  • No platform exploits or attacking competition infrastructure.
  • No sharing flags during the competition.
  • Organizers may review chat history and disqualify violations. All decisions are final.
  • Flag disputes can be submitted at cybercup.ai/contact-us.

Participants may compete individually or as part of a team.
