Kali Linux is a Linux distribution designed for digital forensics and penetration testing. It is maintained and funded by Offensive Security. The software is based on the testing branch of the Debian Linux Distribution: most packages Kali uses are imported from the Debian repositories. Kali Linux has gained popularity in the cybersecurity community due to its comprehensive set of tools designed for penetration testing, vulnerability analysis, and reverse engineering.
It was developed by Mati Aharoni and Devon Kearns of Offensive Security through the rewrite of BackTrack, their previous information security testing Linux distribution based on Knoppix.
Kali Linux was featured in multiple episodes of the TV series Mr. Robot.
