Understanding OpenBullet 2: The Modern Evolution of Automation

In the world of web automation and security testing, OpenBullet has long been a household name. With the release of OpenBullet 2, the project has transitioned from a Windows-specific tool to a powerful, cross-platform framework. Built from the ground up using .NET Core, OpenBullet 2 is designed for developers, penetration testers, and data enthusiasts who need a flexible environment to automate web requests. What is OpenBullet 2?

OpenBullet 2 is a web testing suite that allows users to perform requests towards a target web application. While its predecessor was a desktop-only application, OpenBullet 2 is a web-based application. This means you can host it on a remote server (VPS) and access the interface via any browser, making it ideal for 24/7 automation tasks. At its core, it is used for:

Data Scraping: Extracting large amounts of information from websites.

Penetration Testing: Testing the resilience of login forms and APIs against brute-force or credential stuffing (always with permission).

Automated UI Testing: Verifying that web elements work as intended.

API Interaction: Simplifying complex sequences of API calls. Key Features and Improvements 1. Cross-Platform Compatibility

Unlike the original version which relied on Windows Forms, OpenBullet 2 runs on Windows, Linux, and macOS. This is made possible by the move to ASP.NET Core and Blazor. 2. Native Puppeteer and Selenium Support

While the original was focused mainly on HTTP requests, OpenBullet 2 integrates Puppeteer and Selenium. This allows users to automate "headless" browsers, making it much easier to interact with modern, JavaScript-heavy websites that block standard HTTP clients. 3. The "Stack" System

OpenBullet 2 uses a visual "stack" system for building configurations. You can drag and drop blocks (like HTTP Request, Parsing, or Scripting) to create a logic flow. For advanced users, it also supports LoliCode, a dedicated scripting language that gives you full control over the automation logic. 4. Multi-User Support

Because it is a web app, OpenBullet 2 supports multiple user accounts with different permission levels. This is perfect for teams working on shared automation projects. Getting Started: Installation

Setting up OpenBullet 2 is straightforward, especially if you have a basic understanding of terminal commands.

Install the Runtime: You’ll need the .NET 6 Runtime installed on your machine or server.

Download the Build: Grab the latest release from the official OpenBullet 2 GitHub repository.

Run the App: Execute dotnet OpenBullet2.dll in your terminal.

Access the Dashboard: By default, the app runs on http://localhost:5000. Open this in your browser to begin the setup wizard. Responsible Use and Ethics

It is crucial to highlight that OpenBullet 2 is a neutral tool. While it is powerful for data mining and security auditing, it is frequently associated with "credential stuffing"—the unauthorized testing of leaked passwords.

Always ensure you have explicit permission before running a configuration against a website. Unauthorized access to computer systems is illegal and unethical. Use OpenBullet 2 to sharpen your coding skills, automate your own boring tasks, or secure your own applications. Conclusion

OpenBullet 2 represents a significant leap forward in the automation space. By combining the speed of HTTP requests with the versatility of browser automation, it provides a comprehensive toolkit for anyone looking to interact with the web at scale. Whether you are a security researcher or a data scientist, its modularity and cross-platform nature make it a top-tier choice for your workflow.

LoliCode scripting: Includes a custom markdown language for advanced users who prefer coding over visual blocks. Core Concepts and Terminology

To master OpenBullet 2, you need to understand its core building blocks: 1. Configurations (Configs)

Configs are the brain of OpenBullet 2. They dictate exactly how the software interacts with a specific website. A config includes the target URL, the data to send, how to bypass captchas, and how to read the website's response to determine if an attempt was successful. 2. Wordlists

A wordlist is a text file containing the data you want to test or input. In security testing, this is usually a list of usernames and passwords (combos). In scraping, it could be a list of product IDs or search terms. 3. Proxies

To prevent your home IP address from being blocked by target websites due to high traffic, OpenBullet 2 routes traffic through proxies. It supports rotating proxies and static lists.

When OpenBullet 2 successfully finds what it is looking for (like a valid login or a specific scraped data point), it records it as a "Hit." How to Install OpenBullet 2

Because it is built on .NET Core, setting up OpenBullet 2 is straightforward. Method 1: Docker (Recommended)

Docker is the easiest way to run OpenBullet 2 on any operating system without worrying about dependencies. Install Docker on your machine.

Run the following command in your terminal:docker run -d -p 5000:5000 openbullet/openbullet2 Open your browser and navigate to http://localhost:5000. Method 2: Manual Installation Download and install the latest .NET Runtime for your OS.

Download the latest compiled release of OpenBullet 2 from its official GitHub repository.

Extract the folder and run OpenBullet2.exe (Windows) or execute dotnet OpenBullet2.dll in the terminal (Linux/macOS). Access the setup via the URL provided in the console. Creating Your First Configuration

Building a configuration is the most critical skill in OpenBullet 2. Here is a simplified workflow of how to create one: Step 1: Analyze the Network Traffic

Before touching OpenBullet, open your target website in a browser. Open the Developer Tools (F12) and go to the Network tab. Perform the action you want to automate (like logging in) and observe the headers, payload, and cookies being sent to the server. Step 2: Replicate the Request In the OpenBullet 2 Web UI, go to Configs and click New. Add a Request Block.

Set the URL to the login or data endpoint you found in Step 1. Set the method (GET or POST).

Map your Wordlist variables (e.g., ) into the post data. Step 3: Parse the Response Add a Keycheck Block or a Parsing Block.

If testing logins, tell OpenBullet to look for specific keywords in the source code that indicate a success (e.g., "Welcome back" or "Logout").

If scraping, use LR (Left/Right) parsing or JSON parsing to extract specific data from the response. Step 4: Test and Run

Use the built-in debugger to test your config with a single credentials set. If it works, save it, move to the Jobs tab, and start a multi-threaded runner with your full wordlist and proxy list. Ethical and Legal Use

While OpenBullet 2 is a neutral automation tool, its high-speed capabilities make it a popular tool for malicious credential stuffing attacks. You must always adhere to strict ethical guidelines:

Permission: Never run OpenBullet 2 against a website or API that you do not own or have explicit written permission to test.

Rate Limiting: Do not overload servers to the point of causing a Denial of Service (DoS).

Compliance: Ensure your data scraping activities comply with local laws and the website's Terms of Service.

OpenBullet 2 is best utilized for automated QA testing of your own web infrastructure, auditing your company's password strength against known breaches, and collecting public data for research.

OpenBullet 2 (OB2) - a tool that's garnered significant attention within certain online communities, particularly among those involved in penetration testing, cybersecurity, and ethical hacking. It's essential to approach this topic with a focus on educational and informative content, ensuring that any discussion around tools like OpenBullet 2 is framed within the context of legal and ethical use.

The Ecosystem: Configs, Builds, and Forums

OpenBullet 2 is just the engine. The power lies in the configs. Writing a reliable config requires reverse-engineering a website’s JavaScript, API calls, and token generation. This has spawned a cottage industry.

Popular darknet forums (e.g., Cracked, Nulled, RaidForums's successors) have dedicated sections for:

OpenBullet 2 Configs: Users share or sell configs for hundreds of services.
Combo Lists: Packaged email:password lists (often labeled "Combolists").
Tutorials: How to bypass Cloudflare, reCAPTCHA, or 2FA using OpenBullet 2.

Because of this ecosystem, even a low-skilled attacker can launch a sophisticated credential stuffing attack against a major bank in minutes.

4. Next-gen Input System (No more LoliScript)

Step 4: The Attack

The attacker loads the combo list, selects a proxy list (to avoid IP blocking), chooses a config, and presses "Start". OpenBullet 2 then launches hundreds of threads, each trying different credentials against the target application.

From Desktop App to Web Framework

The most defining feature of OpenBullet 2 (OB2) is its architectural shift. Unlike its predecessor, which was a standalone Windows desktop application built on the .NET Framework, OB2 was rebuilt from the ground up using ASP.NET Core.

This transition transformed the tool into a web-based application. Users interact with it through a browser interface, much like a web dashboard. This change unlocked significant advantages:

Cross-Platform Compatibility: Because it runs on .NET Core, OB2 is no longer tethered to Windows. It can be hosted and run natively on Linux and macOS, and can even be deployed inside Docker containers.
Remote Access: Users can run OB2 on a remote server (VPS) and manage their testing operations from anywhere in the world via a web browser, without needing a remote desktop connection (RDP).

Plugin System (WebAssembly)

Write custom decoders, analyzers, or notifiers in Rust, Go, or TypeScript → compile to WASM.
Plugin marketplace with code signing and community reviews.

How to Set Up OpenBullet 2 (For Defensive Research)

Warning: Only run this in an isolated lab environment or on systems you own.

Install .NET 8 SDK from Microsoft.
Clone a repository: Many forks exist; the original is periodically DMCA’d. Search GitHub for "OpenBullet 2" – look for recent commits.

Build:

git clone https://github.com/openbullet/OpenBullet2
cd OpenBullet2
dotnet build -c Release

Run:
```
dotnet run --project OpenBullet2
```
Access https://localhost:5000 – default credentials are often admin:admin123 (change immediately).

Do not use production credentials or target real websites without permission.

Distributed Worker Mode

Deploy workers on cloud instances (AWS Lambda, DigitalOcean droplets) with automatic scaling.
Workers communicate over encrypted WebRTC – no central command server logs.

Step 3: Finding or Building Configs

Configs are the brain of OpenBullet 2. They tell the software which URLs to hit, what data to send (POST/GET), how to detect a successful login, and what variables to extract (e.g., auth_token, user_id).

Configs are shared in the underground for specific targets:

Netflix_Check
Spotify_Premium_Config
Paypal_Balance_Check
Amazon_Gift_Card
