New AWS and Azure Marketplace Images
Kali Linux 2023.4 now provides both AMD64 and ARM64 images on the AWS and Azure cloud marketplaces, expanding deployment options. The ARM64 variants allow leveraging the flexible and cost-efficient ARM-based instance types available on both platforms. This leads to an improved price-performance ratio for cloud labs. However, currently, not all Kali packages have ARM64 support yet, though the majority do. The team is continuously working on expanding compatibility.
For guidance on setting up Kali in the cloud or comparing performance benchmarks between the images, check the official documentation. The cloud build scripts are also available to understand and even customize the image generation process. While the ARM gap is being addressed, AMD64 remains the most compatible image for now. The addition of ARM64 still brings more choices to match the needs and budgets for scalable pen testing labs in the cloud.
Vagrant Support for Deploying Kali on Hyper-V
If you are not aware of Vagrant, it is a command-line utility that streamlines building and managing virtual machine environments. It uses simple Vagrantfile configurations to automatically handle VM provisioning, software installation, and orchestration.
Until the release of Kali Linux 2023.4, Kali’s Vagrant file supports two virtualization platforms: VirtualBox and VMware. Now with this release, Kali extended its support for Hyper-V VM deployments. The Kali Vagrant box includes the capability to smoothly create Hyper-V-based Kali VMs on Windows systems. By leveraging Vagrant with Hyper-V, it becomes very convenient to get fully configured Kali penetration testing labs up and running with minimal effort.
So for Windows users, leveraging Vagrant is an easy way to get Kali VMs deployed for your ethical hacking needs.
New Dedicated Image for Installing Kali on Raspberry Pi 5
The Raspberry Pi Foundation recently released the latest addition to their line of compact single-board computers – the Raspberry Pi 5. Kali Linux 2023.4 now offers an install image tailored specifically for the Pi 5 hardware, enabling cybersecurity professionals to leverage the portability and affordability of a Pi for their ethical hacking needs.
The streamlined image can be downloaded directly or installed using Raspberry Pi Imager for a smooth out-of-the-box Kali experience on Pi 5. It currently supports only 64-bit ARM configurations but packs all the great tools you’d expect for penetration testing on the go. The Pi’s GPIO interface allows for added functionality like WiFi auditing once compatible wireless adapters become available.
Overall the Pi 5 dedicated image makes Kali easily portable while tapping into the Pi 5 improvements – perfect for technical hands-on security training.
If you have Raspberry Pi 5 with you and want to install Kali Linux on it. We have a step-by-step guide that shows you the installation of Kali Linux on Raspberry Pi 5.
Change in the Mirror Redirect- Migration from MirrorBrain to MirrorBits
This is the last major change in Kali Linux 2023.4. Kali Linux utilizes mirror redirection services to route software downloads and updates to the nearest available mirror site globally to minimize latency for users while distributing load efficiently across mirror infrastructure.
Previously, this core routing mechanism relied on a mirror manager called MirrorBrain – now Kali has migrated to a more modern platform called MirrorBits after 10 years. Released in 2013, MirrorBrain had become unmaintained, posing challenges. MirrorBits offers enhanced capabilities out-of-the-box by leveraging newer technologies like Go and Redis for very robust routing scalable to millions of files. Originally created for video distribution, MirrorBits sees wide adoption distributing major open-source projects today.
For Kali, the transition involved tailoring it to handle metadata changes inherent in rolling distributions – but it paves the way for long-term stability. The move to Mirrorbits future-proofs Kali infrastructure while making mirror redirects smoother for getting tools/updates quickly.
There are other miscellaneous changes like the include a newsletter provider switch to SubStack for blog post updates. A few bugs got addressed – one causing the virtual machine display freeze after idling, another hampering KDE clipboard functionality. Qt6 theming support was added. And Python package installs change announcements emphasize the pending switch to v3.12 comportment. Please check out the official page for complete details.
