Sulo is a dynamic instrumentation tool for Adobe Flash Player. It is built on Pin.
The following Flash Player builds are supported:
- 10.3.181.23 standalone debug
- 10.3.181.23 standalone non-debug
- 10.3.181.23 ActiveX
- 11.1.102.62 standadlone non-debug
- 11.1.102.62 ActiveX
You can add support for another Flash Player build by specifying some RVAs and offsets in FlashPlayerConfigBuilder.cpp.
Sulo supports ActionScript3 method calls only - AVM1 is not (yet) supported.
The easiest way to build Sulo is to use the sulo_vs2010.sln solution file with Visual Studio 2010.
- Download Intel Pin kit for Visual Studio 2010
- Extract the ZIP
- Clone Sulo to
pin-2.13-65163-msvc10-windows\source\tools\Sulo - Open
sulo_vs2010.slnand build the solution
Sulo comes with three plugins:
- Call tracer - logs all ActionScript method calls, including arguments and return values
- Flash dumper - dumps Flash objects loaded with Loader.loadBytes() to disk
- SecureSWF - logs decrypted strings from secureSWF-protected files
Creating your own plugin is easy: just inherit your class from ISuloPlugin, implement the virtual methods, and add the object to m_plugins in SuloPluginManager::init().
