Kali Linux 2019.2 On the Raspberry Pi Zero W H

The Raspberry Pi Zero WH is the next step for the Pi Zero W product. As with the other Zero W device, the WH provides both wireless networking, and bluetooth on the smaller Raspberry Pi models. The distinct feature addition with the Zero WH is the header pins have been added, thus no additional soldering to the device is needed. These small footprint devices can be utilized for many purposes such as modification of a non-internet enabled device to be monitored and accessed from a network to their use in computer forensics.

The Zero WH is still running a 32 bit 1 Ghz processor, and 512Mb of RAM (the same as the Zero W). This is in contrast to the newly released Raspberry Pi 4 that runs 64bit 1.5 Ghz processor with 1, 2 or 4 Gb of RAM.

Now Kali Linux provided by Offensive Security is a Debian Linux variant that is intended to be utilized as a Penetration Testing OS. and not a daily use operating system. Kali provides weekly updates and it is advise to perform routine device updates if one intends to continue use of the product.

Installation of KAli 2019.2.

1. Secure a micro sd card for use in the Raspberry Pi device. In my efforts a 64 GB sd card was used as it was now close to the same price as the 32 Gb Micro SD card.

2. Navigate to the Kali Linux site and to their download page. On the bottom half of the page is a button to access the Kali Linux ARM images for various devices.

3. Follow the page and select the Raspberry Pi Foundation section, at the bottom of the various images is one entitled "Kali Linux RPi" Download this as other variants are headless variants or are intended for specific purposes.

4. Unzip the compressed file once it is downloaded. Using a file compression software decompress the image file.

5. Writing the image to the Micro SD card. Utilizing a USB or other card reading device, and image writing software such as Etcher or Win32DiskImager write the image to the Micro SD card.

6. Insert the Micro SD card and power up / boot the RPiZWH. Note: Kali Linux Ri P Z images utilize Re4son kernels who is a developer of the Linux OS Kernels for the 32 bit devices. Also the image will perform functions to expand the file system and utilize the full disk space area available on the Micro SD card. These processes were required to be executed by the user in earlier software images.

7. Login Kali Linux default root user account is "Root" and the password "toor"

8. Update and upgrade the system. The Kali Linux distro that the disk image provides is a small footprint without many of the software packages that are available on a full version of the Kali Linux distribution. If other software is needed for one's efforts metapackages "tools" are available. While a complete list of "tools" that are available is here: "tool lists"

9. Updating, open a console terminal and enter the following command: apt-get update && apt-get upgrade. follow the queues in the terminal and updating and upgrading will begin.

10. Currently it appears that Firefox is crashing when opening. Alternative browsers range from Luakit, Midori, Lynx and others. My current alternative is Midori. To install Midori enter the command below:

sudo apt install midori

Midori can be accessed from the internet tab on the applications dropdown.

Next we will set up the remote desktop connection
