We can see that running the scanner without credentials does not return a great deal of information. If, however, you have been provided with credentials as part of a pentest, you will find that the pipe_auditor scanner returns a great deal more information.

As you can see, since this is an un-credentialed scan, access is denied a most of the systems that are probed. Passing user credentials to the scanner will produce much different results.

We can see that running the scan without credentials, only the Linux Samba service coughs up a listing of users. Passing a valid set of credentials to the scanner will enumerate the users on our other targets.

Now that we have passed credentials to the scanner, the Linux box doesn’t return the set of users because the credentials are not valid for that system. This is an example of why it pays to run a scanner in different configurations. smb_login

Metasploit’s smb_login module will attempt to login via SMB across a provided range of IP addresses. If you have a database plugin loaded, successful logins will be stored in it for future reference and usage.

There are many more options available that you should experiment with to fully familiarize yourself with this extremely valuable module. smb_lookupsid

The smb_lookupsid module brute-forces SID lookups on a range of targets to determine what local users exist the system. Knowing what users exist on a system can greatly speed up any further brute-force logon attempts later on.

You will notice with credentialed scanning, that you get, as always, a great deal more interesting output, including accounts you likely never knew existed. smb_version

Contrary to many other cases, a credentialed scan in this case does not necessarily give better results. If the credentials are not valid on a particular system, you will not get any result back from the scan.
