Adobe Flash can be a roadblock and source of frustration for web application penetration testers. Implementation details in the Flash debugger make it difficult to debug the ActionScript code within a release-build SWF file. In this talk, I give a general overview of the process of debugging ActionScript in Flash and AIR SWF files. I then introduce a tool I have written to inject synthetic file and line-number information into release SWF files, converting them into debuggable ones and allowing them to be dynamically analyzed using standard tools.
