LAB Setup 1

1. Tool and LAB Setup with Android Studio

For some exercises we need Android Studio that we can install and emulate android apps. To run a virtualization inside a virtual machine is not even easy and it's possible that the emulator won't work or bring the whole VM to crash. I got it to work inside my Kali Linux box, but it's also possible to run Android Studio native on the client.

If you use Windows you can't use Hyper-V and VMware, because they are in conflict with each other.

Use this command in powershell to disable hyper-v and reboot the machine:

bcdedit /set hypervisorlaunchtype off

My VMware Configuration looks like this:

Download and Install Android Studio:

Install Android Studio  |  Android DevelopersAndroid Developers

Unpack tar.gz file

tar -xvf android-studio-ide-2021.2.1.15-linux.tar.gz -C <DIRECTORY>

Launch Android Studio:

~/android-studio/bin# ./studio.sh

Create an Android virtual Device (AVD) in Android Studio:

Tools --> AVD Manager

Emulator starten:

The emulator is in directory ~/Android/Sdk/emulator

Install apktool:

apt install apktool

Install apksigner:

apt install apksigner

Install adb:

apt install adb

Install Android Asset packaging tool:

apt install aapt

Install jadx:

git clone https://github.com/skylot/jadx.git
cd jadx
./gradlew build
./gradlew dist

./build/jadx/bin/jadx

./build/jadx/bin/jadx-gui

Install Frida:

Frida requires python >=3.6 and should be installed in a virtual environment

pipenv --python 3 shell
pip install frida
pip install frida-tools
pip install objection
pip install frida-android-helper

Workaround if pip install frida-android-helper gets errors:

git clone https://github.com/Hamz-a/frida-android-helper.git
cd frida-android-helper
python3 setup.py install
