Hijacker is a Graphical User Interface for the penetration testing tools Aircrack-ng, Airodump-ng, MDK3 and Reaver. It offers a simple and easy UI to use these tools without typing commands in a console and copy&pasting MAC addresses.
This requires an ARM android device with a wireless adapter that supports Monitor Mode. Cyber security experts said that a few android devices do, but none of them natively. This means that you will need a custom firmware. Nexus 5 and any other device that uses the BCM4339 chipset will work with Nexmon. Devices that use BCM4330 can use bcmon. An alternative would be to use an external adapter that supports monitor mode in Android with an OTG cable.
The required tools are included for armv7l and aarch64 devices as of version 1.1. The Nexmon driver and management utility for BCM4339 are also included. Data security professional comments that root is also necessary, as these tools need root to work.

A data security professional said that you have to make sure: you are on Android 5+, you are rooted, SuperSU is required, if you are on CM/LineageOS install SuperSU, and also have a firmware to support Monitor Mode on your wireless interface.
When you run Hijacker for the first time, you will be asked whether you want to install the nexmon firmware or go to home screen. If you have installed your firmware or use an external adapter, you can just go to the home screen. Otherwise, click ‘Install Nexmon’ and follow the instructions. Keep in mind that on some devices, changing files in /system might trigger an Android security feature and your system partition will be restored when you reboot. After installing the firmware you will land on the home screen and airodump will start. Make sure you have enabled your WiFi and it’s in monitor mode.
