Kali Linux is similar to BackTrack in many ways, but it lays a new foundation and makes substantial improvements that will allow it to be even more useful to penetration testers in the coming years. Many security practitioners have been using BackTrack to perform their security assessments.

Why was BackTrack discontinued?

The backtrack project had to be shut down and moved to the Kali Linux project. This happened because the team wanted a strong and rolling base to work on. The work on Backtrack was stopped and the newer Kali OS based on Debian was launched in 2013.

What is BackTrack used for?

Its only purpose is to test your network, devices, and systems for security vulnerabilities. BackTrack is packed with every security and hacker tool used by security professionals and professional hackers.
