Quietly enumerate an Active Directory Domain via LDAP parsing users, admins, groups, etc. Created by Nick Swink from Layer 8 Security.
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 shellor run commands directly withpipenv run.
⚠️ 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
$ pipenv run python silenthound.py -h
usage: silenthound.py [-h] [-u USERNAME] [-p PASSWORD] [--hashes HASHES] [-o OUTPUT] [-g] [-n] [-k] [--kerberoast] [--ssl] TARGET domain
Quietly enumerate an Active Directory environment.
positional arguments:
TARGET Domain Controller IP
domain Dot (.) separated Domain name including both contexts e.g. ACME.com | HOME.local | htb.net
optional arguments:
-h, --help show this help message and exit
-u USERNAME, --username USERNAME
Supports SIMPLE & NTLM BIND. SIMPLE BIND use username e.g. bobdole | NTLM BIND use domain\\user e.g. HOME.local\\bobdole
-p PASSWORD, --password PASSWORD
LDAP or Active Directory password
--hashes HASHES Uses NTLM BIND to authenticate with NT:LM hashes
-o OUTPUT, --output OUTPUT
Name for output files. Creates output files for hosts, users, domain admins, and descriptions in the current working directory.
-g, --groups Display Group names with user members.
-n, --org-unit Display Organizational Units.
-k, --keywords Search for a list of key words in LDAP objects.
--kerberoast Identify kerberoastable user accounts by their SPNs.
--ssl Use a secure LDAP server on default 636 port.
$ pipenv run python silenthound.py -u 'svc_tgs' -p 'P@$$w0rd123' 10.10.10.100 active.htb -g -n -k --kerberoast

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:
