Certified Ethical Hacker (CEH) Practice Question

During a Wi-Fi penetration test you find an employee's Android handset listening on TCP port 5555 and the banner identifies the service as Android Debug Bridge (ADB). You want the fastest way to get an interactive shell without touching the device physically. Which course of action and prerequisite would most likely let you succeed?

  • Send a Stagefright-based MMS payload, provided the messaging application has not been patched against the vulnerability.

  • Push a malicious over-the-air (OTA) update through the recovery interface, providing the handset's bootloader is already unlocked.

  • Initiate an ADB network session with "adb connect :5555" and drop to an ADB shell, assuming the phone is running Android 4.1 or earlier where ADB over TCP is unauthenticated.

  • Perform a Bluetooth OBEX file-transfer exploit, as long as the device is currently in discoverable pairing mode.
