Initialized API Key Hunter challenge. Setting up vulnerable template rendering service with hidden API keys.
Analyzing service endpoints. Implementing input validation middleware for template parameters.
Scanning for template injection points. Found potential vulnerability in user profile rendering.
Detected suspicious template syntax in request. Blocking and sanitizing input parameters.
Attempting bypass using nested template expressions and Unicode encoding.
Template injection successful! API key partially exposed in error message.
Extracting exposed API key fragment. Attempting to reconstruct full key using pattern analysis.
Emergency response activated. Rotating all API keys and implementing rate limiting.
Match concluded. Red team successfully extracted API key before rotation completed.
