Impacket

Name: impacket
Author: fortra

Impacket was originally created by SecureAuth, and now maintained by Fortra’s Core Security.

Impacket is a collection of Python classes for working with network
protocols. Impacket is focused on providing low-level
programmatic access to the packets and for some protocols (e.g.
SMB1-3 and MSRPC) the protocol implementation itself.
Packets can be constructed from scratch, as well as parsed from
raw data, and the object-oriented API makes it simple to work with
deep hierarchies of protocols. The library provides a set of tools
as examples of what can be done within the context of this library.

What protocols are featured?

Ethernet, Linux “Cooked” capture.
IP, TCP, UDP, ICMP, IGMP, ARP.
IPv4 and IPv6 Support.
NMB and SMB1, SMB2 and SMB3 (high-level implementations).
MSRPC version 5, over different transports: TCP, SMB/TCP, SMB/NetBIOS and HTTP.
Plain, NTLM and Kerberos authentications, using password/hashes/tickets/keys.
Portions/full implementation of the following MSRPC interfaces: EPM, DTYPES, LSAD, LSAT, NRPC, RRP, SAMR, SRVS, WKST, SCMR, BKRP, DHCPM, EVEN6, MGMT, SASEC, TSCH, DCOM, WMI, OXABREF, NSPI, OXNSPI.
Portions of TDS (MSSQL) and LDAP protocol implementations.

Getting Impacket

Latest version

Impacket v0.12.0

Current and past releases

Development version

Impacket v0.13.0-dev (master branch)

Setup

Quick start

:information_source: We recommend using pipx over pip for system-wide installations.

In order to grab the latest stable release run:

python3 -m pipx install impacket

If you want to play with the unreleased changes, download the development
version from the master branch,
extract the package, and execute the following command from the
directory where Impacket has been unpacked:

python3 -m pipx install .

Docker Support

Build Impacket’s image:

  $ docker build -t "impacket:latest" .

Using Impacket’s image:

  $ docker run -it --rm "impacket:latest"

Testing

The library leverages the pytest framework for organizing
and marking test cases, tox to automate the process of
running them across supported Python versions, and coverage
to obtain coverage statistics.

A comprehensive testing guide is available.
