SWFIntruder is the first tool for testing security in SWF files directly in the browser context. This is the original version that was developed in 2007 and hosted on Google Code. It has now been ported to github to let other people fork it or help improving.
Note: SWFIntruder is unmantained since 2008 so if anybody wants to help is welcome, but I won't be able to fix or add new features. Means: At the moment needs some fixing to let it work with modern browsers.
SWFIntruder is a tool developed by Stefano Di Paola and maintained by OWASP in designed to perform a security analysis of Flash applications. It helps to find flaws in Flash applications using the methodology originally described by Stefano Di Paola in Testing Flash Applications (May 2007) and in Finding Vulnerabilities in Flash Applications (Nov 2007).
SWFIntruder was developed using ActionScript, Html and JavaScript resulting in a tool taking advantage of the best features of those technologies in order to get the best capabilities for analysis and interaction with the testing Flash movies.
SWFIntruder was developed by using only open source software. Thanks to its generality, SWFIntruder is OS independent.
Visit SWFIntruder home page for more details and the OWASP Flash Security Project for a broad overview about Flash security.
SWFIntruder purpose is to analyze a Flash application for version =< 8 and to help check in a semi automated fashion the presence of security issues like Cross Site Scripting and Cross Site Flashing.
Moreover does help raise awareness around the subject of flash applications security and how that can be used to and assist in the security of applications.
