Gosecretsdump

Have you been using Impacket to dump hashes out of (large) NTDS.dit files, and become increasingly frustrated at how long it takes? I sure have!

All credit for the original code to the impacket devs, it’s much more complicated than I anticipated.

This is a conversion of the impacket secretsdump module into golang. It’s not very good, but it is quite fast. Please let me know if you find bugs, I’ll try and fix where I can - bonus points if you can provide sample .dit files for me to bash against.

Features

  • Dumps dits very fast. Operations that usually take hours are now done in minutes.
  • Can dump SAM/SYSTEM backups
  • Can dump local SAM/SYSTEM (must be run as the machine account/SYSTEM)
  • A somewhat usable interface for integration other other tooling (See lib example below)

Installation

git clone https://github.com/C-Sto/gosecretsdump.git
cd gosecretsdump
go build

./gosecretsdump [OPTIONS]

gosecretsdump vDEV (@C__Sto)

  -enabled
        Only output enabled accounts

  -livesam
        Get hashes from live system. Only works on local machine hashes (SAM), only works on Windows.
  -noprint
        Don't print output to screen (probably use this with the -out flag)
  -ntds string
        Location of the NTDS file (required)
  -out string

  -sam string
        Location of SAM registry hive
