Android UnCrackeable Level 3

The crack will be performed on a Kali Linux machine.

The installation process for each tool will not be shown, but every step to create the environment will be documented.

To install the .apk an emulator is required. Create an emulator using the following command:

avdmanager create avd -n Android26 -k "system-images;android-26;default;x86_64" -c 10M

Verify that the device has been installed correctly:

avdmanager list avd

Start the emulator as follows:

emulator -avd Android26

Use the following command to list connected devices. Note the device name.

adb devices

Download UnCrackable-Level3.apk and install it on the emulator. Then open the app.

adb -s emulator-5554 install UnCrackable-Level3.apk

The application detects that the device is rooted and immediately closes.

To bypass this, we need to investigate the app for an anti-root check. Android APK Studio will be used for static analysis, although other tools like jadx or apktool can do the same job.

Open Android APK Studio and click “File” -> “Open” -> “APK”, then select UnCrackable-Level2.apk.

Select the “Decompile java?” checkbox and click “Decompile”.
