SWFIntruder – Analysis and Security Testing of Flash Applications

[ad]

With a recent spate of attacks from banner ads (many of which are using flash) this might be a useful tool if you are using flash or more accurately flash applications on your website or portal.

I did mention a Flash decompiler a while back, now we have SWFIntruder (pronounced Swiff Intruder), which is apparently the first tool specifically developed for analyzing and testing security of Flash applications at runtime.

It helps to find flaws in Flash applications using the methodology originally described in Testing Flash Applications and in Finding Vulnerabilities in Flash Applications.

Features

• Basic predefined attack patterns.
• Highly customizable attacks.
• Highly customizable undefined variables.
• Semi automated XSS check.
• User configurable internal parameters.
• Log Window for debugging and tracking.
• History of latest 5 tested SWF files.
• ActionScript Objects runtime explorer in tree view.
• Persistent Configuration and Layout.

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 independant.
