BurpKit

Introduction

Welcome to the next generation of web application penetration testing - using WebKit to own the web. BurpKit is a BurpSuite plugin which helps in assessing complex web apps that render the contents of their pages dynamically. It also provides a bi-directional JavaScript bridge API which allows users to create quick one-off BurpSuite plugin prototypes which can interact directly with the DOM and Burp's extender API.

Installing BurpKit is simple:

1. Download the latest prebuilt release from the GitHub releases page.
2. Open BurpSuite and navigate to the Extender tab.
3. Under Burp Extensions click the Add button.
4. In the Load Burp Extension dialog, make sure that Extension Type is set to Java and click the Select file ... button under Extension Details.
5. Select the BurpKit-<version>.jar file and click Next when done.

If all goes well, you will see three additional top-level tabs appear in BurpSuite:

1. BurpKitty: a courtesy browser for navigating the web within BurpSuite.
2. BurpScript IDE: a lightweight integrated development environment for writing JavaScript-based BurpSuite plugins and other things.
3. Jython: an integrated python interpreter console and lightweight script text editor.

BurpScript

BurpScript enables users to write desktop-based JavaScript applications as well as BurpSuite extensions using the JavaScript scripting language. This is achieved by injecting two new objects by default into the DOM on page load:

1. burpKit: provides numerous features including file system I/O support and easy JS library injection.
2. burpCallbacks: the JavaScript equivalent of the IBurpExtenderCallbacks interface in Java with a few slight modifications.

Take a look at the examples folder for more information.
