Impacket is a collection of Python classes for low-level programmatic access to network protocols, including full implementations of SMB1-3 and MSRPC. It also ships a set of example tools for tasks like authentication with hashes and tickets, remote execution, and Windows protocol interaction.

Use cases

• interact with SMB shares from Python
• perform pass-the-hash attacks during pentests
• craft and parse raw network packets
• query WMI and execute commands on remote Windows hosts
• work with Kerberos tickets and NTLM authentication
• implement MSRPC/DCE-RPC client tooling
• dump credentials or enumerate Windows services remotely

When to choose

• you need low-level Python access to Windows network protocols like SMB, MSRPC, or WMI
• you are doing penetration testing or red team work against Windows/Active Directory environments
• you want to authenticate with hashes, tickets, or keys instead of passwords
• you need to build custom protocol clients from scratch or parse raw packets

When to avoid

• you need a general-purpose high-level networking library for everyday HTTP or TCP work
• you want a cross-platform file sharing client with a GUI
• your project is not Python-based
• you need a passive network sniffer or IDS rather than protocol client tooling
