TrailBlazer is a Python-based tool designed to analyze AWS CloudTrail logging behavior by systematically testing API calls across AWS services. The tool uses the boto3 SDK to enumerate available AWS services and regions, then explores the complete function set for each service to determine which API calls are logged by CloudTrail and how they appear in the logs. TrailBlazer bypasses boto3 client-side validation to send requests with missing or invalid parameters, allowing it to test API calls that would normally be blocked before reaching AWS services. When API calls require no parameters, the tool sends completely valid requests. For calls requiring parameters, it sends intentionally malformed requests that generate "Invalid Parameters" or "Unauthorized" responses in CloudTrail logs. The tool can function as both an analysis framework for understanding CloudTrail coverage and as an attack simulation platform for testing detection capabilities. It provides insights into the inconsistencies in CloudTrail logging across different AWS services and API endpoints.
