What is Impacket?

Impacket is a collection of Python classes for working with network protocols. Impacket is mostly focused on providing low-level programmatic access to the packets, however some protocols (for instance NMB and SMB) are implemented in a higher level as a foundation for other protocols. 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.

Impacket is most useful when used together with a packet capture utility or package such as Pcapy, an object oriented Python extension for capturing network packets.

What protocols are featured?

• Ethernet, Linux ``Cooked'' capture.
• IP, TCP, UDP, ICMP, IGMP, ARP. (IPv4 and IPv6)
• NMB and SMB1/2/3 (high-level implementations).
• DCE/RPC versions 4 and 5, over different transports: UDP (version 4 exclusively), TCP, SMB/TCP, SMB/NetBIOS and HTTP.
• Portions of the following DCE/RPC interfaces: Conv, DCOM, EPM, SAMR, SCMR, RRP, SRVSC, LSAD, LSAT, WKST, NRPC.

Getting Impacket

Current and past releases are available from http://corelabs.coresecurity.com/index.php?module=Wiki&action=view&type=tool&name=Impacket Trunk available from http://code.google.com/p/impacket/

Setup

Quick start

Grab the latest stable release, unpack it and run 'python setup.py install' from the directory where you placed it. Isn't that easy?

Requirements

• A Python interpreter. Versions 2.0.1 and newer are known to work. a) If you want to run the examples and you have Python < 2.7, you will need to install argparse package for them to work. b) For Kerberos support you will need pyasn1 package c) For cryptographic operations you will need pycrypto package d) For some examples you will need pyOpenSSL (rdp_check.py) e) If you're under Windows, you will need pyReadline
• A recent release of Impacket.

Installing

In order to install the source execute the following command from the directory where the Impacket's distribution has been unpacked: 'python setup.py install'. This will install the classes into the default Python's modules path; note that you might need special permissions to write there. For more information on what commands and options are available from setup.py, run 'python setup.py --help-commands'.
