can be to used dump Group Policy Preferences passwords. Unlike other similar tools, this utility doesn't mount the remote SYSVOL share from the DC, it uses streams instead to navigate the share and carve file contents.


It has the following generic command line arguments, similar to many other tools:

  • required positional argument: [[domain/]username[:password]@]<targetName or address> or LOCAL if the user wants to parse a local file (e.g. domain.local/user@dc01, domain/user:password@

  • -hashes: the LM and/or NT hash to use for a pass-the-hash (NTLM). The format is as follows: [LMhash]:NThash (the LM hash is optional, the NT hash must be prepended with a colon (:).

  • -aesKey: the AES128 or AES256 hexadecimal long-term key to use for a pass-the-key authentication (Kerberos).

  • -k: this flag must be set when authenticating using Kerberos. The utility will try to grab credentials from a Ccache file which path must be set in the KRB5CCNAME environment variable. In this case, the utility will do pass-the-cache. If valid credentials cannot be found or if the KRB5CCNAME variable is not or wrongly set, the utility will use the password specified in the positional argument for plaintext Kerberos authentication, or the NT hash (i.e. RC4 long-term key) in the -hashes argument for overpass-the-hash. A Kirbi file could also be converted to a Ccache file using in order to be used by the utility (indirect pass-the-ticket).

  • -no-pass: this flag must be set when an empty password will by used, or no password at all. Without this flag, the user will be prompted for a password when running the utility. This flag is especially useful when using -k.

  • -dc-ip: IP address of the domain controller. If omitted, the positional argument's domain part will be used (in that case, it must be a Fully-Qualified-Domain-Name (FQDN)).

  • -debug: with this flag set, the utility will be more verbose and will possibly print useful information for debug purposes. With this flag set, the utility will also print tracebacks.

  • -ts: with this flag set, the utility will prepend all output with a timestamp.


It also has the following specific command line arguments:

  • -target-ip: IP address of the target machine. If omitted, the positional argument's target part will be used. This argument is useful when NetBIOS name resolution request fail.

  • -port: remote TCP port the utility must connect to. By default, the port is set to 445 since SMB is the protocol used.

  • -xmlfile: the path to the local .xml file to parse

  • -share: the name of the SMB share to search GPP passwords in. By default, this is set to SYSVOL.

  • -base-dir: the directory to search in. By default, this is set to /. With a default value in -share, it makes the utility start the search in \\target\SYSVOL\.

# with a NULL session -no-pass 'DOMAIN_CONTROLLER'

# with cleartext credentials 'DOMAIN'/'USER':'PASSWORD'@'DOMAIN_CONTROLLER'

# pass-the-hash (with an NT hash) -hashes :'NThash' 'DOMAIN'/'USER':'PASSWORD'@'DOMAIN_CONTROLLER'

# parse a local file -xmlfile '/path/to/Policy.xml' 'LOCAL'
