Description
This module will try to find Service Principal Names that are associated with normal user accounts.
Since normal accounts' passwords tend to be shorter than machine accounts, and knowing that a TGS request
will encrypt the ticket with the account the SPN is running under, this could be used for an offline
bruteforcing attack of the SPNs account NTLM hash if we can gather valid TGS for those SPNs.
