Android’s adb shell provides powerful debugging capabilities, but its interaction with symbolic links inside /sdcard/Android/data/ poses hidden risks. This paper analyzes a novel attack vector where a malicious or repurposed privileged API (here named moeshizukuprivilegedapi ) leverages a crafted startsh link inside storage/emulated/0/Android/data/ to escalate from ADB shell permissions to access protected app data directories. We demonstrate how a simple sh script executed via this link can break Android’s scoped storage model, and propose forensic detection methods.
Paste and run the full command: adb shell sh /storage/emulated/0/Android/data/moe.shizuku.privileged.api/start.sh .
You might also use a shortened version of the path: Paste and run the full command: adb shell
Once your environment is set up, follow these steps to execute the command and initiate the Shizuku service. Step 1: Connect the Device
: This part tells the computer to open a command-line interface (shell) on the connected Android device to execute a local command. : Once active, it provides a bridge for
: Once active, it provides a bridge for other apps to perform actions normally restricted by Android, such as accessing the /Android/data or obb folders on newer Android versions.
To use Shizuku, you need three things:
ADB is an essential tool for Android developers, as it provides a way to test and debug apps on a physical device. However, it's also useful for enthusiasts who want to explore the inner workings of their device.
