Overview
Welcome to the OWASP Interceptor Project for XML Processing. The Interceptor tool is designed to easily assist security testers in performing attacks against XML Web Services and AJAX interfaces. The utility allows testers to capture a sample XML request and then replay/fuzz requests against the Web Service.

A tester can also preload an automated attack database for each request into the tool, and Interceptor will fuzz and replay each attack against the service and provide results.

The Welcome Screen (And Interface) of the Interceptor Project.

Goals
The Goal of this project was to develop a simple, quick and easy to use tool that could capture and save XML requests and then allow testers to easily replay the request with fuzzed data. Thus allowing the quick testing of the XML Web Service interfaces without the need to use TCP request processors or additional proxies to manipulate and replay handcrafted attack data.


 * Please help with this project. We would like to be able to create a "GENERIC" XML attack list of common types of XML attacks that can be configured as a pre-loaded attack database in Interceptor. Contact the Project Team with any ideas.

Future Development
OK, After a while of not much developer, interceptor is back into full swing. Thanks to some new team members with b-sec, we are now developing a release which can be treated as 1.0 and will run on all the latest versions of windows etc (including VISTA). If you have anything you want us to add or change let us know.

News
June-July 2007, Work on Version 1.0 is happening and the next release will come up within a month. This will fix the VISTA problems etc.
