Linux is an extremely popular operating system for hackers. First of all, Linux's source code is freely available because it is an open-source Operating System (OS). This means that Linux is very easy to modify and customize. Second, there are countless Linux security distributions available. Almost all the Ethical Hacking operating systems for security experts are based on a Linux kernel.
Keep in mind that, simply having these operating systems does not make anyone a security expert or a hacker. It is extremely important to develop your Linux skills to become an "Ethical Hacker". Nearly all the tools that hackers use are developed for Linux. Linux gives us capabilities that we don't have using Windows.

BlackArch is a complete Linux distribution for penetration testers and security researchers. It is derived from Arch Linux and users can install BlackArch components individually or in groups directly on top of it. The toolset is distributed as an Arch Linux unofficial user repository so you can install BlackArch on top of an existing Arch Linux installation. Packages may be installed individually or by category.
The constantly expanding repository currently includes over 2400 tools. All tools are thoroughly tested before being added to the code base to maintain the quality of the repository. You can find all BlackArch Linux code including build scripts and website source on Github, however, BlackArch is a Linux pen-testing distribution based on ArchLinux. If you're not familiar with ArchLinux, we strongly suggest you avoid BlackArch due to the learning curve for new users.
