Kali Everywhere

Undercover Mode

Using Kali in an environment where you don’t want to draw attention to yourself? Kali Undercover is the perfect way to not stand out in a crowd.

Kali NetHunter

A mobile penetration testing platform for Android devices, based on Kali Linux. Kali NetHunter is made up of an App, App Store, Kali Container and KeX

Win-KeX

Win-KeX provides a full Kali Desktop Experience for Windows WSL. Applications started via Kali’s panel will share the desktop with Microsoft Windows applications.

ARM

Cheap & low powered devices, which make for great leave behind devices. Modern ARM based laptops provide high speed with long battery life as an assessment platform.

Bare Metal

Single or multiple boot Kali, giving you complete control over the hardware access (perfect for in-built WiFi and GPU), enabling the best performance.

Cloud

Hosting providers which have Kali Linux pre-installed, ready to go, without worrying about looking after the infrastructure.

Containers

Using Docker or LXD, allows for extremely quick and easy access to all of Kali’s tools, without the overhead of a isolated virtual machine.

Mobile

A mobile penetration testing platform for Android devices, based on Kali Linux. Kali NetHunter consists of an NetHunter App, App Store, Kali Container, and KeX.

USB

Kali in your pocket, ready to go with Live Boot. Your Kali, always with you, without altering the host OS, plus allows you to benefit from hardware access.

Virtual Machines

VMware & VirtualBox pre-built images ready to go. Allowing for a Kali install as bare as possible, with additional features such as snapshots, without altering the host OS. And we have vagrant images too.

WSL

WSL is included out of the box with modern Windows. You can then start to use Kali (and Win-Kex) without any installing any extra software.

Choose the desktop you prefer

Xfce

Xfce is a lightweight desktop environment for UNIX-like operating systems. It aims to be fast and low on system resources, while still being visually appealing and user friendly.

Xfce consists of separately packaged parts that together provide all functions of the desktop environment, but can be selected in subsets to suit user needs and preferences. This is Kali’s default desktop environment.

GNOME Shell

Every part of GNOME Shell has been designed to make it simple and easy to use. The Activities Overview is an easy way to access all your basic tasks. A press of a button is all it takes to view your open windows, launch applications, or check if you have new messages. Having everything in one place is convenient and means that you don’t have to learn your way through a maze of different technologies.

KDE Plasma

Plasma is made to stay out of the way as it helps you get things done. But under its light and intuitive surface, it’s a powerhouse. So you’re free to choose ways of usage right as you need them and when you need them.

With Plasma the user is king. Not happy with the color scheme? Change it! Want to have your panel on the left edge of the screen? Move it! Don’t like the font? Use a different one! Download custom widgets in one click and add them to your desktop or panel.

Pip install and Python’s externally managed

TL;DR: pip install is on the way out. Installing Python packages must be done via APT, aka. Kali Linux’s package manager. Python packages coming from other sources should be installed in virtual environments. Long story below. Some background Back in February this year, for a few days, some of you might have tried (and failed) to install Python packages with Pip, aka.

Kali linux open source

Kali Linux (formerly known as BackTrack Linux) is an open-source, Debian-based Linux distribution aimed at advanced Penetration Testing and Security Auditing. It does this by providing common tools, configurations, and automations which allows the user to focus on the task that needs to be completed, not the surrounding activity.

Kali Linux contains industry specific modifications as well as several hundred tools targeted towards various Information Security tasks, such as Penetration Testing, Security Research, Computer Forensics, Reverse Engineering, Vulnerability Management and Red Team Testing.

Kali Linux is a multi-platform solution, accessible and freely available to information security professionals and hobbyists.

Kali Linux Features

• More than 600 penetration testing tools included: After reviewing every tool that was included in BackTrack, we eliminated a great number of tools that either simply did not work or which duplicated other tools that provided the same or similar functionality. Details on what’s included are on the Kali Tools site.
• Free (as in beer) and always will be: Kali Linux, like BackTrack, is completely free of charge and always will be. You will never, ever have to pay for Kali Linux.
• Open source Git tree: We are committed to the open source development model and our development tree is available for all to see. All of the source code which goes into Kali Linux is available for anyone who wants to tweak or rebuild packages to suit their specific needs.
• FHS compliant: Kali adheres to the Filesystem Hierarchy Standard, allowing Linux users to easily locate binaries, support files, libraries, etc.
• Wide-ranging wireless device support: A regular sticking point with Linux distributions has been support for wireless interfaces. We have built Kali Linux to support as many wireless devices as we possibly can, allowing it to run properly on a wide variety of hardware and making it compatible with numerous USB and other wireless devices.
• Custom kernel, patched for injection: As penetration testers, the development team often needs to do wireless assessments, so our kernel has the latest injection patches included.
• Developed in a secure environment: The Kali Linux team is made up of a small group of individuals who are the only ones trusted to commit packages and interact with the repositories, all of which is done using multiple secure protocols.
• GPG signed packages and repositories: Every package in Kali Linux is signed by each individual developer who built and committed it, and the repositories subsequently sign the packages as well.
• Multi-language support: Although penetration tools tend to be written in English, we have ensured that Kali includes true multilingual support, allowing more users to operate in their native language and locate the tools they need for the job.
• Completely customizable: We thoroughly understand that not everyone will agree with our design decisions, so we have made it as easy as possible for our more adventurous users to customize Kali Linux to their liking, all the way down to the kernel.
• ARMEL and ARMHF support: Since ARM-based single-board systems like the Raspberry Pi and BeagleBone Black, among others, are becoming more and more prevalent and inexpensive, we knew that Kali’s ARM support would need to be as robust as we could manage, with fully working installations for both ARMEL and ARMHF systems. Kali Linux is available on a wide range of ARM devices and has ARM repositories integrated with the mainline distribution so tools for ARM are updated in conjunction with the rest of the distribution.
• For more features of Kali Linux, please see the following page: Kali Linux Overview.

Kali Linux is specifically tailored to the needs of penetration testing professionals, and therefore all documentation on this site assumes prior knowledge of, and familiarity with, the Linux operating system in general. Please see Should I Use Kali Linux? for more details on what makes Kali unique.
