Impacket Description

Security Operations/Offensive Security

Smb Ntlm Packet Crafting Active Directory

Impacket is a collection of Python classes for working with network protocols. It provides 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.
