go-smb

Description

Package go-smb is a work in progress to create a go library that implements an SMB2/3 client with support for DCERPC and MSRRP. This project was created as a way to learn how to interact remotely with Windows services and the remote registry.

It is based upon the work of https://github.com/stacktitan/smb but has seen a lot of changes to add support for SMB3, DCERPC and MSRRP where parts of the code are taken from another go-smb project located at https://github.com/hirochachacha/go-smb2.
