Hi,
as said lots of times, BackBox offers a light and complete pentesting environment, but c'mon guys... that's a linux distro, non one is limited to the stock tools. New software can be easily added, this cannot be the reason to change distro (IMHO).
So, including non-stock tools in the distro is easy. You can do two things:
1. create the live USB in persistent mode and install all tools you need;
2. add the tools modifying the downloaded ISO following this wiki:
http://wiki.backbox.org/index.php/Customize_the_Live_DVD and then burn it on a non-persistent USB.
This way you will have the tools you need, you can customize boot-up services, autostart apps, conf files and so on...
OT: Stolas can you explain better:
"Well I stopped using BackBox after Backtrack got their act together." ?
Thank you guys.
Have fun!
