The most advanced penetration testing distribution, ever.

From the creators of BackTrack comes Kali Linux, the most advanced and versatile penetration testing distribution ever created. We have a whole set of amazing features lined up in our security distribution, geared at streamlining the penetration testing experience.

Fanatic ARM Hardware Support

Raspberry Pi, Odroid, Cubox, Beaglebones, Chromebooks, we got Kali Images for them all. We are obsessed with getting Kali on as many interesting ARM machines we can get our hands on, and we've got quite an impressive list so far. Our motto, when it comes to the world of ARM is "Kali all the things!". Know of an interesting piece of ARM we don't yet support? Mail us!

Kali Linux Nethunter

The Kali Linux NetHunter project is the first Open Source Android penetration testing platform for Nexus devices, created as a joint effort between the Kali community member “BinkyBear” and Offensive Security. NetHunter supports Wireless 802.11 frame injection, one-click MANA Evil Access Point setups, HID keyboard (Teensy like attacks), as well as BadUSB MITM attacks – and is built upon the sturdy shoulders of the Kali Linux distribution and toolsets.
