Presentation: Reverse Engineering ASP .Net 2.0 Viewstate
Date: August [27,29], 2008
Summary: This presentation discusses the process I followed to reverse engineer the LosFormat and some of the .Net 2.0 types. Peekviewstate is a python script that will parse viewstate on a Unix system. The parser relies on predefined classes or strucutures that are discovered during testing. As more types or structures are discovered, the better the parser will become. Additionally, the parser can be used to add in arbitrary objects, but this functionality will not work until EventValidation for the ViewState is modified to match the ViewState. This presentation was also used in an interview for a teaching position on the 29th of August.
