I was over at Distrowatch the other day and they had a distro that just got updated called BackBox Linux. It's a distro a bit like Kali that has security focused tools included. When I first looked I thought it said BlackBox Linux. I thought "BlackBox Linux? what the heck could that be?" So a few tag lines popped into my head.
BlackBox Linux - Not even the developers know how it works.
BlackBox Linux - If you can't figure out how it works, then the bad guys won't either!
BlackBox Linux - Security focused. Randomly changes executable names each time it runs.
Oh well.
