Burp Suite Extender API: Creating Custom Session Token Plugins

During web application security testing, static or complex session handling can stall automated scans and manual assessments. Understanding how to interact with session-related data programmatically allows you to bypass these roadblocks and maintain active, authenticated states. This course teaches you how to leverage the Burp Suite Extender API to build custom plugins that dynamically update and manage session tokens. You will start with the foundational concepts of the Extender API, learning how Burp Suite processes extensions and handles HTTP traffic. From there, you will progress to writing clean, functional code to intercept, modify, and inject custom session tokens into outgoing requests, ensuring your testing workflow remains uninterrupted. What you'll learn: - Understand the core architecture of the Extender API and how extensions interact with HTTP traffic - Configure your development environment to write and load custom security plugins - Intercept HTTP requests and responses to extract dynamic session tokens - Modify session-related headers and body parameters programmatically on the fly - Apply modern secure coding practices to ensure your custom plugins run efficiently and securely - Troubleshoot and debug extension code using built-in logging tools This text-based course guides you step-by-step from foundational API concepts to writing your first custom session-handling plugin. It is designed for beginner to intermediate security researchers, penetration testers, and developers who want to extend their web application testing capabilities. No prior extension development experience is required, though a basic understanding of HTTP and security testing concepts is recommended.
