Use Android as Rubber Ducky against another Android device

HID attack using Android

Using Android as Rubber Ducky against Android. This is not a new technique, just a demo how to perform HID attack using Android instead of rubber ducky. For targeted Android device it is not necessary to be rooted, have ADB/USB debugging enabled and device authorized, since attacker's smartphone behaves as connected keyboard.

How to prevent this happening

1. charge you smartphone using your own adapter
2. use none trivial PIN or password lockscreen protection
3. use mobile security software that will detect and prevent from launching payloads

PoC

Prerequisites

• rooted Android with HID kernel support (e.g. NetHunter ROM)
• OTG cable
