Abstract:

Knowing how the components of mobile applications interact is a prerequisite to many security analyses. However, no analysis can readily infer all Inter-Component Communication (ICC) precisely. Further, because Android applications are compiled from Java source into platform-specific Dalvik bytecode, existing program analysis tools cannot be used to evaluate their behavior. This talk shows how we retarget Android applications to Java bytecode using our Dare tool in order to perform static security analysis on them. We successfully retarget 99.99% of the 262,110 classes in a sample of 1,100 applications. Using retargeting as a first step, we develop a static program analysis to infer the values of ICC messages. The resulting Epicc tool can infer ICC messages in 93% of the cases in a corpus of 1,200 applications. This makes it possible to use Dare and Epicc as the basis of many different inter-component security analyses. I will also discuss how to generalize the concepts developed in Epicc to infer values of other kinds of objects for security analyses in contexts other than mobile applications. I will additionally present future directions in security analyses of program code.
