Droidbox – Android Application Sandbox

Droidbox is a dynamic analysis platform for android applications. Droidbox was developed by Patrik Lantz as part of GSoc 2011. You can try it out by downloading Android Reverse Engineering virtual machine, which bundels droidbox as well as additional android malware analysis tools.


About Droidbox

DroidBox is developed to offer dynamic analysis of Android applications. The following information is described in the results, generated when analysis is complete:

  • Hashes for the analyzed package
  • Incoming/outgoing network data
  • File read and write operations
  • Started services and loaded classes through DexClassLoader
  • Information leaks via the network, file and SMS
  • Circumvented permissions
  • Cryptographic operations performed using Android API
  • Listing broadcast receivers
  • Sent SMS and phone calls

Additionally, two graphs are generated visualizing the behavior of the package. One showing the temporal order of the operations and the other one being a treemap that can be used to check similarity between analyzed packages.

This is a guide to get DroidBox running. The release has only been tested on Linux and Mac OS. If you do not have the Android SDK, download it from http://developer.android.com/sdk/index.html. The following libraries are required: pylab and matplotlib to provide visualization of the analysis result.

  • Export the path for the SDK tools
export PATH=$PATH:/path/to/android-sdk/tools/
export PATH=$PATH:/path/to/android-sdk/platform-tools/
  • Download necessary files and uncompress it anywhere
wget https://github.com/pjlantz/droidbox/releases/download/v4.1.1/DroidBox411RC.tar.gz
  • Setup a new AVD targeting Android 4.1.2 and choose Nexus 4 as device as well as ARM as CPU type by running:
  • Start the emulator with the new AVD:
./startemu.sh <AVD name>
  • When emulator has booted up, start analyzing samples (please use the absolute path to the apk):
./droidbox.sh <file.apk> <duration in secs (optional)> 

The analysis is currently not automated except for installing and starting packages. Ending the analysis is simply done by pressing Ctrl-C. A package will also be implemented soon to populate the emulator with data prior to performing analysis.
