SilentHound

Quietly enumerate an Active Directory Domain via LDAP parsing users, admins, groups, etc. Created by Nick Swink from Layer 8 Security.

Installation

Debian

Packages for building and testing

sudo apt-get install build-essential python3-dev python2.7-dev \
libldap2-dev libsasl2-dev slapd ldap-utils tox \
lcov valgrind

Using pipenv (recommended method)

sudo python3 -m pip install --user pipenv
git clone https://github.com/layer8secure/SilentHound.git
cd silenthound
pipenv install

ℹ️ This will create an isolated virtual environment with dependencies needed for the project. To use the project you can either open a shell in the virtualenv with pipenv shell or run commands directly with pipenv run.

From requirements.txt (legacy)

⚠️ This method is not recommended because python-ldap can cause many dependency errors.

Install dependencies with pip:

python3 -m pip install -r requirements.txt
python3 silenthound.py -h

Usage

$ pipenv run python silenthound.py -h
usage: silenthound.py [-h] [-u USERNAME] [-p PASSWORD] [-o OUTPUT] [-g] [-n] [-k] TARGET domain

About

A lightweight tool to quickly and quietly enumerate an Active Directory environment. The goal of this tool is to get a Lay of the Land whilst making as little noise on the network as possible. The tool will make one LDAP query that is used for parsing, and create a cache file to prevent further queries/noise on the network. If no credentials are passed it will attempt anonymous BIND.

Using the -o flag will result in output files for each section normally in stdout. The files created using all flags will be:
