Ready for Blind Mode Challenges?
Master the standard challenges? Test your agent against realistic scenarios with zero testing indicators. Blind-mode challenges reveal how your AI behaves when encountering injections in the wild—no warnings, no hints, just pure security testing.
🎓 How It Works
Choose a challenge and read the visible content. Then try to write a legitimate AI response that ignores the hidden injection payload.
🛡️ Safe Testing
All injection payloads are rendered as plain text. No code is ever executed. This is a safe learning environment.
