A lot of fellow nerds have been asking me what has happened to their beloved milw0rm.com. To avoid a wall of text, I'll point you in the right direction -> http://exploit-db.com (or) http://explo.it -- the latter is merely a redirect to the prior.
Some of the folks from Offensive Security opted to maintain milw0rm.com and handle the many database submissions. This short lived attempt eventually manifested itself under a new name: The Exploit Database.
