Last updated: November 19, 2016 | 3,098 views

Androguard is a toolkit built in Python which provides reverse engineering and malware analysis for Android.

Androguard - Reverse Engineering & Malware Analysis For Android

It’s buyilt to examine * Dex/Odex (Dalvik virtual machine) (.dex) (disassemble, decompilation), * APK (Android application) (.apk), * Android’s binary xml (.xml) and * Android Resources (.arsc).

Androguard is available for Linux/OSX/Windows (Python powered).

Features

Map and manipulate DEX/ODEX/APK/AXML/ARSC format into full Python objects
Diassemble/Decompilation/Modification of DEX/ODEX/APK format
Decompilation with the first native (directly from dalvik bytecodes to java source codes) dalvik decompiler (DAD)
Access to the static analysis of the code (basic blocks, instructions, permissions)
Analysis a bunch of android apps
Analysis with ipython/Sublime Text Editor
Diffing of android applications
Measure the efficiency of obfuscators (proguard, …)
Determine if your application has been pirated (plagiarism/similarities/rip-off indicator)
Check if an android application is present in a database (malwares, goodwares ?)
Open source database of android malware
Detection of ad/open source librairies (WIP)
Risk indicator of malicious application
Reverse engineering of applications (goodwares, malwares)
Transform Android’s binary xml (like AndroidManifest.xml) into classic xml
Visualize your application with gephi (gexf format), or with cytoscape (xgmml format), or PNG/DOT output
Integration with external decompilers (JAD+dex2jar/DED/fernflower/jd-gui…)

Usage

Androguard has many different components, but the most commonly used one would be Androlyze:

Usage: androlyze.py [options]

Options:
  -h, --help            show this help message and exit
  -i INPUT, --input=INPUT
                        file : use this filename
  -d, --display         display the file in human readable format
  -m METHOD, --method=METHOD
                        display method(s) respect with a regexp
  -f FIELD, --field=FIELD
                        display field(s) respect with a regexp
  -s, --shell           open a shell to interact more easily with objects
  -v, --version         version of the API
  -p, --pretty          pretty print !
  -t TYPE_PRETTY, --type_pretty=TYPE_PRETTY
                        set the type of pretty print (0, 1) !
  -x, --xpermissions    show paths of permissions
