I've written often about the BackTrack suite of security assessment and penetration testing tools. Slap BackTrack on a bootable USB drive and you're ready to wreak security geek havoc anytime, anyplace.
Darknet reports the release of FRHACK OS v1 alpha1, an updated and tweaked version of BackTrack 4 that contains fixes and additional tools.
I can't wait to try it out. You have to be somewhat Linux-friendly to work with either BackTrack or FRHACK, but it's a good way for the Wintel crowd to get some exposure outside of their comfort area.
