OpenBAS: An Open-Source Breach And Attack Simulation Tool For Cybersecurity Testing

2025-02-15

In the ever-evolving landscape of cybersecurity, ensuring the effectiveness of your security controls is paramount. Breach and Attack Simulation (BAS) tools have emerged as a critical solution for organizations looking to continuously test and verify their defenses. One such tool is OpenBAS, an open-source BAS platform developed by Filigran.

OpenBAS is designed to help organizations plan and execute a wide range of simulations, from technical to strategic levels. It leverages knowledge from the OpenCTI platform to provide a comprehensive overview of security gaps, enabling teams to identify and address vulnerabilities proactively. The tool supports collaborative work, real-time monitoring, and feedback management, making it a versatile solution for cybersecurity teams.

One of the standout features of OpenBAS is its ability to integrate with various inject types, including emails, SMS platforms, social media, and alarm systems. This integration enhances the tool’s effectiveness by allowing teams to simulate real-world attack scenarios across multiple communication channels.

Getting Started with OpenBAS

To get started with OpenBAS, you can download the tool from its official repository. Below are some basic commands to set up and run OpenBAS on a Linux system:


<h1>Clone the OpenBAS repository</h1>

git clone https://github.com/filigran/openbas.git

<h1>Navigate to the OpenBAS directory</h1>

cd openbas

<h1>Install dependencies</h1>

sudo apt-get update
sudo apt-get install docker docker-compose

<h1>Build and start the OpenBAS containers</h1>

docker-compose up -d

Once the containers are up and running, you can access the OpenBAS web interface by navigating to `http://localhost:8080` in your web browser. From there, you can start creating and executing simulation scenarios tailored to your organization’s needs.

Example: Simulating a Phishing Attack

To simulate a phishing attack using OpenBAS, you can use the following steps:

Create a New Scenario: In the OpenBAS interface, create a new scenario and define the objectives of the simulation.
Add Injections: Add email injections to simulate phishing emails. You can customize the content and target recipients.
Execute the Scenario: Run the scenario and monitor the results in real-time.
Analyze the Results: Use the feedback management tools to analyze the effectiveness of your security controls and identify areas for improvement.

What Undercode Say

In the realm of cybersecurity, tools like OpenBAS are indispensable for organizations aiming to stay ahead of potential threats. By simulating real-world attack scenarios, OpenBAS allows teams to identify and address vulnerabilities before they can be exploited by malicious actors. The tool’s integration with various communication channels and its ability to provide real-time feedback make it a powerful asset for any cybersecurity team.

For those looking to enhance their cybersecurity posture, OpenBAS offers a flexible and open-source solution that can be tailored to meet the unique needs of any organization. Whether you’re simulating phishing attacks, testing incident response protocols, or conducting strategic exercises, OpenBAS provides the tools you need to ensure your defenses are up to the task.

To further enhance your cybersecurity skills, consider exploring additional resources and tools such as:

OpenCTI: An open-source threat intelligence platform that integrates with OpenBAS.
Metasploit: A penetration testing framework that can be used in conjunction with OpenBAS for more advanced simulations.
Kali Linux: A Linux distribution tailored for cybersecurity professionals, offering a wide range of tools for penetration testing and security auditing.

By leveraging these tools and continuously testing your security controls, you can build a robust defense against the ever-growing threat landscape. Remember, in cybersecurity, preparation and proactive measures are key to staying one step ahead of potential attackers.
