Penetration Testing Linux distros are a group of special purpose Linux distros used for analyzing and evaluating security measures of a target. These kinds of distributions are usually live-cd or USB drive-based, but the newer ones have the ability to be installed as a standalone Linux distribution on your computer. The main users of pen-test distribution are network and computer security enthusiasts, security students, and audit firms who do security audits with the customer’s permission on their network.
Pen-testing distros have come a long way since I first used them about 10 years ago. They used to be unstable and almost always live-cd only. It wasn’t easy to have the packages updated with the latest binaries. We don’t have those problems anymore as nowadays it’s much easier to create a custom distro with custom repositories. Let’s look at some of the more widely used pen-test distros out there:
1. BackTrack:
Probably the most widely known pen-test distro out there and one of the oldest distro still being actively developed. There are thumb-drive and Live DVD version, plus the ability to do a full install in your hard-drive. The distribution is based on Ubuntu with custom packages that get updated on a regular basis.

2. Knoppix-STD:
Another old-timer live distro based on knoppix. STD stands for Security Tools Distro, to avoid any confusion. Contains 1000s of security tools but not advised to be installed as a stand-alone OS.

3. Backbox Linux:
Another Ubuntu based distro but uses XFCE as its window manager and relies on its own repo to constantly keep its tools updated.

4. Blackbuntu:
Built on Ubuntu 10.10 and Gnome, this distro was specifically designed to train students and researchers of information security

5. Samurai Web Testing Framework:
Based on Ubuntu and gnome based live CD. Designed specifically for information gathering and pen-testing web apps.

6. NodeZero Linux:
Yet another Ubuntu LTS based distro but the emphasis is on native install not a live distro. Currently work is being node to get its own package repository for regular updates.

7. WEAKERTH4N:
Based on Debian Squeeze and Fluxbox, its possible to have native HDD install. There is an emphasis on supporting more radios and Wireless pen-test tools out of the box.

8. CAINE :
Based on Ubuntu and MATE Desktop Environment, this is a highly customized pen-test distro that sets it apart from other distro with a useful forensic report generation tool.

9. Pentoo:
A livecd based on Gentoo and XFCE. Also available as an overlay for existing Gentoo installations. Has the ability to crack passwords using GPGPU out of the box.

10. Bugtraq:
Not to be confused with Bugtraq security mailing list. The current version Bugtraq 2 Black Widow available with XFCE, Gnome and KDE based on Ubuntu, Debian and OpenSuse. Unique scripts for SVN updates tools, delete tracks, backdoors, Spyder-sql.

11. Matriux :
“With Matriux, you can turn any system into a powerful penetration testing toolkit, without having to install any software into your harddisk. Matriux is designed to run from a Live environment like a CD / DVD or USB stick or it can easily be installed to your hard disk in a few steps. Matriux also includes a set of computer forensics and data recovery tools that can be used for forensic analysis and investigations and data retrieval.”

12. Matriux :
“DEFT 7 is based on the new Kernel 3 (Linux side) and the DART (Digital Advanced Response Toolkit) with the best freeware Windows Computer Forensic tools. It’s a new concept of Computer Forensic system that uses LXDE as desktop environment and WINE for execute Windows tools under Linux and mount manager as tool for device management.”
