Wide Open: On Purpose
There are many specialty Linux distros out there that are targeted at a specific audience. In the spirit of Damn Small Linux (DSL), comes Damn Vulnerable Linux. This is a Linux distro that has every conceivable exploit enabled. It serves many purposes including testing a new IDS box as well as something to wager on (i.e. how long it would take to get a rootkit installed if it is put un-firewalled directly on the Internet).
While this is done on purpose, it evokes this quote from the movie Spaceballs:
"1-2-3-4-5? That's the stupidest combination I've ever heard of in my life! That's the kinda thing an idiot would have on his luggage!"
This is actually pretty old news, but I meant to post it a while back. Just because it is old doesn't make it any less cool. ;)
