Abstract

A binary application suitable for the .Net framework is disassembled into human readable code. Or, CIL or MSIL code is obtained. The methods are put into a representation indicating which methods of the code call other methods. A source method call chain having a source API and a sink method call chain having a sink API are discerned from the representation. APIs are put into the same format as the methods to allow matching. A method in common between the two call chains indicates that a privacy leak exists. The application is downloaded from a remote server to a computing device where the analysis occurs.
