Analysis of Android Applications

Please, check how to contact me on my personal website.

StaDynA is a system supporting security app analysis in the presence of dynamic code update features (dynamic class loading and reflection).

Our tool combines static and dynamic analysis of Android applications in order to reveal the hidden/updated behavior and extend static analysis results with this information.

This work has been done at the University of Trento.

The results of our research were presented at the 5th ACM Conference on Data and Application Security and Privacy (ACM CODASPY 2015). Please use the following bibtex reference to cite our paper:

Our tool consists of two parts: a server and a client. The server side of StaDynA is a Python program that interacts with a static analysis tool. Currently, StaDynA uses AndroGuard as a static analyzer. The client side is the code run either on a real device or on an emulator.

The instructions how to build client side can be found in the corresponding folder.

To run the analysis of an Android application, after connecting a device running client side, execute the server side Python script:

python stadyna.py -i <inputApk> -o <resultFolder>

where inputApk is a path to the apk file to be analyzed, and resultFolder is the path where the results of the analysis will be stored.
