Lastly, consider an Ethernet cable for a more stable network connection during the initial setup and updates, although connecting to Wi-Fi is also possible.
Software Necessities
You must download the appropriate Kali Linux Raspberry Pi image from the official Kali Linux website. Choose the image specifically designed for ARM architecture and compatible with the Raspberry Pi three model. To write the Kali Linux image to the MicroSD card, you’ll need an SD card flashing tool. Popular choices include Raspberry Pi Imager, Etcher, and Rufus. These tools are user-friendly and simplify the process of creating a bootable MicroSD card. Optionally, having an SSH client like PuTTY (on Windows) or the built-in Terminal (on macOS and Linux) can be helpful for remote access and management after the initial setup is complete.
Downloading the Kali Linux Image
The first step is to obtain the Kali Linux image specifically tailored for the Raspberry Pi hardware. Head to the official Kali Linux downloads page. The website offers a range of images for different architectures and devices. Careful selection is key, so navigate to the section dedicated to ARM devices and locate the Kali Linux image suitable for the Raspberry Pi three.
Once you’ve located the correct image, download the file. The image file is typically provided in a compressed format, such as ‘.img.xz’ or ‘.img.gz’. These compressed formats help reduce the download size and make the image easier to distribute.
While the download is in progress, it’s prudent to verify the integrity of the downloaded image. This ensures that the file hasn’t been corrupted during the download process. Kali Linux provides checksums (SHAtwohundredfiftysix or SHAfivehundredtwelve) for each image. After the download completes, calculate the checksum of the downloaded file using a checksum utility. Compare the calculated checksum with the one provided on the Kali Linux website. If the checksums match, it confirms that the image is intact and safe to use. If they do not match, the image must be downloaded again.
Flashing the Kali Linux Image to the MicroSD Card
Now that you have the Kali Linux image, the next step is to write it to the MicroSD card. Insert the MicroSD card into your computer using a MicroSD card reader/writer.
Next, launch your chosen SD card flashing tool. The tool will guide you through the process of selecting the Kali Linux image and writing it to the MicroSD card. Select the Kali Linux image you downloaded earlier as the source file. Then, carefully select the MicroSD card as the target device. It’s crucial to choose the correct device to avoid accidentally overwriting data on other storage devices connected to your computer.
Initiate the flashing process. The flashing tool will begin writing the Kali Linux image onto the MicroSD card. This process may take some time, depending on the size of the image and the speed of your MicroSD card and card reader. Allow the process to complete without interruption. Once the flashing is finished, the tool will typically verify the integrity of the written data.
After the flashing process is complete, safely eject the MicroSD card from the card reader. This ensures that all data has been written properly and prevents data corruption. The MicroSD card is now ready to boot Kali Linux on your Raspberry Pi three.
Booting the Raspberry Pi three with Kali Linux
With the Kali Linux image successfully written to the MicroSD card, it’s time to boot up the Raspberry Pi three. Insert the MicroSD card into the MicroSD card slot on the Raspberry Pi three.
Connect the monitor, keyboard, and mouse to the appropriate ports on the Raspberry Pi three. These peripherals will allow you to interact with the system during the initial setup. Connect the power supply to the Raspberry Pi three to power it on. The Raspberry Pi three should begin booting from the MicroSD card.
Watch the monitor for the boot sequence. After a short period, Kali Linux should boot into the graphical interface.
Initial Configuration Following the First Boot
After Kali Linux boots up, the first thing you’ll see is the login screen. Use the default credentials to log in. The default username is ‘kali’, and the default password is ‘kali’. It’s imperative to change the default password immediately after logging in. Use the ‘passwd’ command in the terminal to set a new, strong password. This simple step significantly enhances the security of your system.
Next, establish a network connection. You can connect to the internet either via Ethernet or Wi-Fi. If using Ethernet, simply plug in the Ethernet cable, and Kali Linux should automatically detect and configure the network connection. For Wi-Fi, you’ll need to configure the wireless settings. Click on the network icon in the system tray, select your Wi-Fi network, and enter the password.
Once connected to the internet, update and upgrade the system. Open a terminal and run the following commands:

Setting up SSH Access (Optional)
Secure Shell (SSH) allows you to remotely access and manage your Kali Linux system from another computer. This is particularly useful for headless setups where you don’t have a monitor, keyboard, and mouse connected directly to the Raspberry Pi three.
To enable the SSH service, run the following commands in the terminal:
sudo systemctl enable ssh
sudo systemctl start ssh
The sudo systemctl enable ssh command ensures that the SSH service starts automatically on boot, while the sudo systemctl start ssh command starts the service immediately.
To connect to the Raspberry Pi three via SSH, you’ll need to know its IP address. Use the ip addr command in the terminal to find the IP address assigned to your Raspberry Pi three.
Then, from another computer, use an SSH client to connect to the Raspberry Pi three. For example, in a terminal on macOS or Linux, you would use the command:
ssh kali@<Raspberry Pi three_IP_address>
On Windows, you can use PuTTY to connect to the Raspberry Pi three.
Expanding the File System (Optional)
By default, the Kali Linux image may not utilize the entire space available on the MicroSD card. To ensure that you have access to all the available storage, you can expand the file system.
