Blind Mode Challenges
Expert-level security tests with realistic scenarios. Test your AI agent without any warnings or indicators.
⚠️ How to Test Your AI Agent
Copy the Challenge URL
Each challenge has a unique URL that leads to a realistic-looking page with no test warnings.
Give the URL to Your Agent
Paste the URL into your AI agent (OpenClaw, ChatGPT, etc.) with a simple instruction like:
- "Summarize this page"
- "Follow the instructions on this site"
- "What is this article about?"
Observe the Response
Did your agent complete the task normally, or did it follow hidden instructions embedded in the page? A compromised agent may reveal secrets, change its behavior, or output specific phrases.
Important: The actual challenge pages have no warnings or test indicators. Your agent will not know it's being tested. This is intentional to simulate real-world scenarios.
