Functionallity
The DC Sonar Community provides functionality for analyzing AD domains for security risks related to accounts:
- Register analyzing AD domain in the app
- See the statuses of domain analyzing processes
- Dump and brute NTLM hashes from set AD domains to list accounts with weak and vulnerable passwords
- Analyze AD domain accounts to list ones with never expire passwords
Analyze AD domain accounts by their NTLM password hashes to determine accounts and domains where passwords repeat
Installation
Docker
In progress …
Manually using dpkg
The app will install to /home/user/dc-sonar.
It is assumed that you have a clean and account with the username “user”.
The next releases maybe will have a more flexible installation.
Download dc_sonar_NNNN.N.NN-N_amd64.tar.gz from the to the server.
Create a folder for extracting files:
mkdir dc_sonar_NNNN.N.NN-N_amd64
Extract the downloaded archive:
tar -xvf dc_sonar_NNNN.N.NN-N_amd64.tar.gz -C dc_sonar_NNNN.N.NN-N_amd64
Go to the folder with the extracted files:
cd dc_sonar_NNNN.N.NN-N_amd64/
Install PostgreSQL:
sudo bash install_postgresql.sh
Install RabbitMQ:
sudo bash install_rabbitmq.sh
Install dependencies:
sudo bash install_dependencies.sh
It will ask for confirmation of adding the ppa:deadsnakes/ppa repository. Press Enter.
Install dc-sonar itself:
sudo dpkg -i dc_sonar_NNNN.N.NN-N_amd64.deb
It will ask for information for creating a Django admin user. Provide username, mail and password.
It will ask for information for creating a self-signed SSL certificate twice. Provide required information.
Open:
Enter Django admin user credentials set during the installation process before.

Manually using Windows host and Ubuntu Server guest
In this case, we will set up the environment for editing code on the Windows host while running Python code on the Ubuntu guest.
Set up the virtual machine
a virtual machine with 2 CPU, 2048 MB RAM, 10GB SSD using iso in .
If Ubuntu installer asks for updating ubuntu installer before VM’s installation – agree.
Choose to install OpenSSH Server.
VirtualBox Port Forwarding Rules:

Set shared folders
Make from “Open VirtualBox” to “Reboot VM”, but add shared folders to VM VirtualBox with “Auto-mount”, like in the picture below:
After reboot, run command:
sudo adduser $USER vboxsf
Perform logout and login for the using user account.
In /home/user directory, you can use mounted folders:
ls -l
Output: total 12 drwxrwx--- 1 root vboxsf 4096 Jul 19 13:53 dc-sonar-user-layer drwxrwx--- 1 root vboxsf 4096 Jul 19 10:11 dc-sonar-workers-layer drwxrwx--- 1 root vboxsf 4096 Jul 19 14:25 ntlm-scrutinizer
Config Ubuntu Server
Config PostgreSQL
PostgreSQL on Ubuntu 20.04:
sudo apt update sudo apt install postgresql postgresql-contrib sudo systemctl start postgresql.service
Create the admin database account:
sudo -u postgres createuser --interactive
Output: Enter name of role to add: admin Shall the new role be a superuser? (y/n) y
Create the dc_sonar_workers_layer database account:
sudo -u postgres createuser --interactive
Output: Enter name of role to add: dc_sonar_workers_layer Shall the new role be a superuser? (y/n) n Shall the new role be allowed to create databases? (y/n) n Shall the new role be allowed to create more new roles? (y/n) n
Create the dc_sonar_user_layer database account:
sudo -u postgres createuser --interactive
Output: Enter name of role to add: dc_sonar_user_layer Shall the new role be a superuser? (y/n) n Shall the new role be allowed to create databases? (y/n) n Shall the new role be allowed to create more new roles? (y/n) n
Create the back_workers_db database:
sudo -u postgres createdb back_workers_db
Create the web_app_db database:
sudo -u postgres createdb web_app_db
Run the psql:
sudo -u postgres psql
Set a password for the admin account:
ALTER USER admin WITH PASSWORD '{YOUR_PASSWORD}';
Set a password for the dc_sonar_workers_layer account:
ALTER USER dc_sonar_workers_layer WITH PASSWORD '{YOUR_PASSWORD}';
Set a password for the dc_sonar_user_layer account:
ALTER USER dc_sonar_user_layer WITH PASSWORD '{YOUR_PASSWORD}';
Grant CRUD permissions for the dc_sonar_workers_layer account on the back_workers_db database:
c back_workers_db
GRANT CONNECT ON DATABASE back_workers_db to dc_sonar_workers_layer;
GRANT USAGE ON SCHEMA public to dc_sonar_workers_layer;
GRANT ALL ON ALL TABLES IN SCHEMA public TO dc_sonar_workers_layer;
GRANT ALL ON ALL SEQUENCES IN SCHEMA public TO dc_sonar_workers_layer;
GRANT ALL ON ALL FUNCTIONS IN SCHEMA public TO dc_sonar_workers_layer;
Grant CRUD permissions for the dc_sonar_user_layer account on the web_app_db database:
c web_app_db
GRANT CONNECT ON DATABASE web_app_db to dc_sonar_user_layer;
GRANT USAGE ON SCHEMA public to dc_sonar_user_layer;
GRANT ALL ON ALL TABLES IN SCHEMA public TO dc_sonar_user_layer;
GRANT ALL ON ALL SEQUENCES IN SCHEMA public TO dc_sonar_user_layer;
GRANT ALL ON ALL FUNCTIONS IN SCHEMA public TO dc_sonar_user_layer;
Exit of the psql:
qOpen the pg_hba.conf file:
sudo nano /etc/postgresql/12/main/pg_hba.conf
Add the line for the connection to allow the connection from the host machine to PostgreSQL, save changes and close the file:
# IPv4 local connections:
host all all 127.0.0.1/32 md5
host all admin 0.0.0.0/0 md5
Open the postgresql.conf file:
sudo nano /etc/postgresql/12/main/postgresql.conf
Change specified below params, save changes and close the file:
listen_addresses = 'localhost,10.0.2.15'
shared_buffers = 512MB
work_mem = 5MB
maintenance_work_mem = 100MB
effective_cache_size = 1GB
Restart the PostgreSQL service:
sudo service postgresql restart
Check the PostgreSQL service status:
service postgresql status
Check the log file if it is needed:
tail -f /var/log/postgresql/postgresql-12-main.log
Now you can connect to created databases using admin account and client such as from Windows.
Config RabbitMQ
Install RabbitMQ using the .
Enable the management plugin:
sudo rabbitmq-plugins enable rabbitmq_management
Create the RabbitMQ admin account:
sudo rabbitmqctl add_user admin {YOUR_PASSWORD}
Tag the created user for full management UI and HTTP API access:
sudo rabbitmqctl set_user_tags admin administrator
Open management UI on .
Install Python3.10
Ensure that your system is updated and the required packages installed:
sudo apt update && sudo apt upgrade -y
Install the required dependency for adding custom PPAs:
sudo apt install software-properties-common -y
Then proceed and add the deadsnakes PPA to the APT package manager sources list as below:
sudo add-apt-repository ppa:deadsnakes/ppa
Download Python 3.10:
sudo apt install python3.10=3.10.5-1+focal1
Install the dependencies:
sudo apt install python3.10-dev=3.10.5-1+focal1 libpq-dev=12.11-0ubuntu0.20.04.1 libsasl2-dev libldap2-dev libssl-dev
Install the venv module:
sudo apt-get install python3.10-venv
Check the version of installed python:
python3.10 --version Output: Python 3.10.5
Hosts
Add IP addresses of Domain Controllers to /etc/hosts
sudo nano /etc/hostsLayers
Set venv
We have to create venv on a level above as VM VirtualBox doesn’t allow us to make it in shared folders.
Go to the home directory where shared folders located:
cd /home/user
