Good news for Kali Linux fans, the team in charge of Kali Linux has launched a new project, known as nethunter, which works on a device Android and more particularly designed for physical attacks (via the USB port).
For those who don't know Kali Linux is an open source operating system based on Debian which brings together all the tools necessary for security testing of an information system.
If you have a Nexus phone, you can turn it into penetration testing tool by installing Kali Linux NetHunter on it and carrying out attacks using, among other things, the USB port of the target machine.
NetHunter's goal is to provide a penetration testing platform Android bringing together all the tools necessary for pentests of all kinds. Designed to compromise systems over USB when installed and running on a phone Android.
We find in NetHunter, the entire set of Kali Linux tools, including self-destruction or remote control (VNC, etc.) functionalities.
Nethunter is currently available for Nexus devices only (Nexus 5, Nexus 7, Nexus 10). For more information, I invite you to consult the official website of the Kali Linux Nethunter project.
