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.

January 2016: 0.9.14:
1) Library improvements:
* [MS-TSCH] - ATSVC, SASec and ITaskSchedulerService Interface implementations
* [MS-DRSR] - Directory Replication Service DRSUAPI Interface implementation
* Network Data Representation (NDR) runtime overhaul. Big performance and reliability improvements achieved
* Unicode support (optional) for the SMBv1 stack (by @rdubourguais)
* NTLMv2 enforcement option on SMBv1 client stack (by @scriptjunkie)
* Kerberos support for TDS (MSSQL)
* Extended present flags support on RadioTap class
* Old DCERPC runtime code removed

2) Examples improvements:
* Added Kerberos authentication support
* It now uses ITaskSchedulerService interface, adding support for Windows 2012 R2
* If no file to upload and execute is specified (-E) it just dumps the target user's hashes by default
* Added -c option to execute custom commands in the target (by @byt3bl33d3r)
a. Active Directory hashes/Kerberos keys are dumped using [MS-DRSR] (IDL_DRSGetNCChanges method)
by default. VSS method is still available by using the -use-vss switch
b. Added -just-dc (Extract only NTDS.DIT NTLM Hashes and Kerberos) and
-just-dc-ntlm ( only NTDS.DIT NTLM Hashes ) options
c. Added resume capability (only for NTDS in DRSUAPI mode) in case the connection drops. Use -resumefile option
d. Added Primary:CLEARTEXT Property from supplementalCredentials attribute dump ([MS-SAMR]
e. Add support for multiple password encryption keys (PEK) (by @s0crat)
* Tests all DCs in domain and adding forest's enterprise admin group inside PAC

3) New examples:
* Child domain to forest privilege escalation exploit. Implements a child-domain to forest privilege
escalation as detailed by Sean Metcalf at
* Gets a list of the sessions opened at the remote hosts and keep track of them (original idea by @mubix)
