Kali Linux, formerly known as Backtrack, promotes itself as a more polished replacement with more testing-centric tools, as opposed to Backtrack, which had numerous tools that served the same goal, resulting in it being bloated with unneeded utilities. This makes ethical hacking using Kali Linux much easier.
It's a rebuild of BackTrack made by Offensive Security, and it's at the top of our list as one of the greatest hacking systems. This Debian-based OS comes with over 500 preconfigured pen testing tools and programmes to help you get started with security.
