Instructions

Step 1: Configure Kali Linux Repositories

The first step is to set correct Kali Linux repositories. Make sure that your /etc/apt/sources.list file contains the following official Kali repositories: 

• deb https://http.kali.org/kali kali-rolling main non-free contrib

• deb-sources https://http.kali.org/kali kali-rolling main non-free contrib 

  WARNING
  Use only official Kali Linux repositories. Any other listed 3rd-party and unofficial repositories within the /etc/apt/sources.list file may break or compromise your Kali Linux system.

  Step 2: Update Kali Linux

  To begin the update of your Kali Linux system first update the packages index list. Open up terminal and enter: 

• sudo apt update

  Next, optionally, display all packages which are scheduled for update:  

  • apt list --upgradable

     

    At this stage we have an option to upgrade individual packages using apt install PACKAGE-NAME or upgrade all packages at once : 

    • sudo apt upgrade

                            All done. Your Kali Linux system is now fully upgraded.

    Step 3: Upgrade Kept Back Packages

    Due to package dependency changes some of the Kali Linux packages might be kept back.
    
    If this is this case you will be notified by the apt upgrade Linux command at the end of the Kali Linux upgrade process. You may upgrade each kept back package individually using the apt install PACKAGE-NAME command or update all kept back packages at once: 

  • •  $ sudo apt dist-upgrade
      

    Step 4: Uninstall No Longer Required Packages

    During your initial system upgrade some of the packages may become obsolete, hence are no longer required. To remove all no longer required Kali Linux packages execute:

    • $ sudo apt autoremove

The Advanced HID keyboard is like a Teensy device but you can SSH to it over 3G.

Sean Brown Penetration Tester

As an experienced penetration tester or security professional, it is imperative that you trust the tools you work with. One way to achieve this trust is by having full transparency and familiarity with the code you are running. You are free to read, investigate, and change our build scripts for the NetHunter images. All of this goodness from the house of Offensive Security and developers of Kali Linux!

HID Keyboard and ‘BadUSB’ Attacks

Our NetHunter images support programmable HID keyboard attacks, (a-la-teensy), as well as “BadUSB” network attacks, allowing an attacker to easily MITM an unsuspecting target by simply connecting their device to a computer USB port. In addition to these built in features, we’ve got a whole set of native Kali Linux tools available for use, many of which are configurable through a simple web interface.

Configuration Management

The Kali NetHunter configuration interface allows you to easily configure complex configuration files through a local web interface. This feature, together with a custom kernel that supports 802.11 wireless injection and preconfigured connect back VPN services, make the NetHunter a formidable network security tool or discrete drop box – with Kali Linux at the tip of your fingers wherever you are!.
