Android Pentesting with Genymotion and Burp

Our previous blog post (without Genymotion) and getting started guide is here.

Download & Install Genymotion (Android Emulator)

Download and follow prompts, https://www.genymotion.com/download/

Choose a device and API version. I’m using API version 8.0 for this setup.

Install ARM translation tool for Genymotion

Genymotion is x86-based, so if you try to install an application including ARM code on any Genymotion device, you will get an error that you wouldn’t get it on a physical device.

Failure [INSTALL_FAILED_NO_MATCHING_ABIS: Failed to extract native libraries, res=-113]

To avoid the error message, install ARM translation tool that match your API level. In this case, I installed 8.0 version.

Start the device and install Burp CA Certificate

Download and install burp suite if you don’t have it installed, https://portswigger.net/burp/communitydownload

Download burp certificate from ProxyàOptionsàImport/export CA Certificate

Download and rename it to .cer format

Drag and drop to Genymotion emulator and it will be stored under /sdcard/Downloads folder.

Install the certificate, default values work fine. You will be prompted to setup a security PIN.

‍Setup manual proxy in Genymotion & Burp

Setup Burp proxy via ProxyàOptionsàAdd. Select All Interfaces and specify proxy port.

Setup proxy in Genymotion via:

SettingsàNetwork & InternetàWi-fiàLong click & hold AndroidWifiàModify networkà<<Local IP and Proxy port>>

Bingo, you are now setup to intercept all traffic between your Android application and server.

Install ADB via brew

brew install android-platform-tools

adb devices

Download APK file

Download target application and install on Android emulator

A quick and easy way to download Android APK file is via Chrome extension:

Once you have the APK file, just drag and drop to Genymotion or issue command:

adb install <<filename.apk>>

Intercept the traffic

You should now be able to intercept the traffic for your target Android application.

Happy Hacking !!!
