Certified Ethical Hacker (CEH) Practice Question

During a red-team engagement, you recover an unattended corporate smartphone running Android 12. The screen is locked and the bootloader is still locked, but USB debugging was left enabled and the device has previously trusted your laptop's ADB RSA key. With only minutes of physical access, which built-in attack vector lets you deploy a backdoored application and obtain a reverse shell without further user interaction?

  • Use the trusted ADB session to run adb install and silently sideload the malicious APK.

  • Reboot the phone into fastboot mode and flash a modified system image containing your payload.

  • Send a crafted WAP-Push Service Indication (SI) SMS that forces the device to download and install your application.

  • Transfer the APK via NFC Android Beam and rely on automatic installation when the devices touch.
