check this site: http://milw0rm.com/cracker/ it daily gives vulnerabilities info and provide h@cking tools
milw0rm is not a hacking site its a security site which informs users of the glitches in the script they use so its safe from hackers
But you know hackers are using this site to get exploits for specific application. Some times I even get some zero-day exploits also. Actually it was created to help admins to patch the vulnerabilities in their server or network, but hackers are the only people who are utilising this site properly to attack.
