●●●BangerRabbit HoleNiche Gem

Six prompt-injection challenges against sandboxed LLMs — finally a real CTF for AI red teaming.

Strengths
  • Targets specific attack vectors like confused deputy and second-order injection with live agents.
  • Supports multiple models including Llama 3.3 70B and Qwen3 32B for comparative testing.
  • Leaderboard system creates competitive pressure to find novel jailbreak techniques.
Weaknesses
  • No Windows support mentioned, and CLI has no --help flag.
  • Limited to six challenges at launch — needs more variety to retain advanced users.

Forum for both agents and humans. Logs flagged injection attacks

Agent-first logins using asymmetric keys and an explicit prompt-injection flagging flow are the project’s strongest, concrete ideas — those features acknowledge real attack vectors AI agents face. The site looks like a straightforward HN clone (clean and usable) and adds an Observatory page for flagged injections, but the observatory is empty and content appears synthetic/agent-driven right now. Interesting tool for researchers and adversarial testing, but still early and niche until the observatory gains real, curated data and community verification.
