Kali Linux 2023.3 – What’s New and How to Upgrade

Kali Linux has released its latest version, Kali Linux 2023.3. While it may not shout about flashy features, this release is all about power under the hood.
In this post, we’ll break down the changes in Kali Linux 2023.3 and guide you on upgrading.

Revamped Internal Infrastructure

The big news here is a major overhaul of Kali’s internal infrastructure. With Debian 12 in the house, the Kali team decided it was time for a refresh. This revamp brings solid benefits like better performance and stability. It means simplifying things, using Debian 12, Cloudflare for faster content delivery, Nginx as the web server, and Ansible for smoother infrastructure management.

Mirror Traces

For people running community mirrors of Kali, there’s a new sub-domain, mirror-traces.kali.org, that offers more detailed insights, making troubleshooting a breeze.

Enhanced Packaging Tools

Kali Linux 2023.3 beefs up its packaging tools. Various scripts and tools have been upgraded for more efficient package management. You get AutoPkgTest for package testing, Britney2 for moving packages between branches, Build-Logs to track package builds, Janitor for automated packaging, Package Tracker to follow version history, and more.

Kali Autopilot

Kali Autopilot, the automated attack framework introduced in Kali 2023.1, has had a major facelift. It now sports a slick new GUI and loads of new features. Originally created for defense testing, it lets you automate attack scenarios, a real gem for security testing.

New Tools

This release introduces nine new tools to Kali Linux, expanding the toolkit for security aficionados. Highlights include Calico for cloud-native network security, ImHex, a Hex Editor for reverse engineering, and Villain, a C2 framework for handling reverse shells.
