Network protocols Constructors and Dissectors

Project Description

Impacket is a collection of Python classes focused on providing access to network packets. Impacket allows Python developers to craft and decode network packets in simple and consistent manner.

June 2016: 0.9.15:
1) Library improvements
* SMB3.create: define CreateContextsOffset and CreateContextsLength when applicable (by @rrerolle)
* Retrieve user principal name from CCache file allowing to call any script with -k and just the target system (by @MrTchuss)
* Packet fragmentation for DCE RPC layer mayor overhaul.
* Improved pass-the-key attacks scenarios (by @skelsec)
* Adding a minimalistic LDAP/s implementation (supports PtH/PtT/PtK). Only search is available (and you need to
build the search filter yourself)
* IPv6 improvements for DCERPC/LDAP and Kerberos

2) Examples improvements
* Adding -dc-ip switch to all examples. It allows to specify what the IP for the domain is. It assumes the DC and KDC
resides in the same server
* secretsdump.py
a. Adding support for Win2016 TP4 in LOCAL or -use-vss mode
b. Adding -just-dc-user switch to download just a single user data (DRSUAPI mode only)
c. Support for different ReplEpoch (DRSUAPI only)
d. pwdLastSet is also included in the output file
e. New structures/flags added for 2016 TP5 PAM support
* wmiquery.py
a. Adding -rpc-auth-level switch (by @gadio)
* smbrelayx.py
a. Added option to specify authentication status code to be sent to requesting client (by @mgeeky)
b. Added one-shot parameter. After successful authentication, only execute the attack once for each target (per protocol)

3) New Examples
* GetUserSPNs.py: This module will try to find Service Principal Names that are associated with normal user account.
This is part of the kerberoast attack researched by Tim Medin (@timmedin)
* ntlmrelayx.py: smbrelayx.py on steroids!. NTLM relay attack from/to multiple protocols (HTTP/SMB/LDAP/MSSQL/etc)
