Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

How could one have a copy of the smb-check-vulns scripts ? My local nmap installation (version 4.68) does not come with one bundled.

If you get this:

You MUST get nmap-4.85BETA5 because earlier versions won't scan for Conficker.


Install info:

bzip2 -cd nmap-4.85BETA6.tar.bz2 | tar xvf -

cd nmap-4.85BETA6



su root

make install
