Impacket v0.9.10 (March 2013):

  1. Library improvements

    • SMB version 2 and 3 protocol support ([MS-SMB2]). Signing supported, encryption for SMB3 still pending.
    • Added a SMBConnection layer on top of each SMB specific protocol. Much simpler and SMB version independent. It will pick the best SMB Version when connecting against the target. Check smbconnection.py for a list of available methods across all the protocols.
    • Partial TDS implementation ([MS-TDS] & [MC-SQLR]) so we could talk with MSSQL Servers.
    • Unicode support for the smbserver. Newer OSX won't connect to a non unicode SMB Server.
    • DCERPC Endpoints' new calls
      • EPM: lookup(): It can work as a general portmapper, or just to find specific interfaces/objects.

  2. New examples

    • mssqlclient.py: A MS SQL client, allowing to do MS SQL or Windows Authentication (accepts hashes) and then gives you an SQL prompt for your pleasure.
    • mssqlinstance.py: Lists the MS SQL instances running on a target machine.
    • rpcdump.py: Output changed. Hopefully more useful. Parsed all the Windows Protocol Specification looking for the UUIDs used and that information is included as well. This could be helpful when reading a portmap output and to develop new functionality to interact against a target interface.
    • smbexec.py: Another alternative to psexec. Less capabilities but might work on tight AV environments. Based on the technique described at https://www.optiv.com/blog/owning-computers-without-shell-access. It also supports instantiating a local smbserver to receive the output of the commandos executed for those situations where no share is available on the other end.
    • smbrelayx.py: It now also listens on port 80 and forwards/reflects the credentials accordingly.

And finally tons of fixes :).

Impacket v0.9.9 (July 2012):

    • DCERPC Endpoints' new calls:

    • lookupsid.py: DCE/RPC lookup sid brute forcer example.
    • opdump.py: This binds to the given hostname:port and DCERPC interface. Then, it tries to call each of the first 256 operation numbers in turn and reports the outcome of each call.
