"OpenBullet 2" is a security testing tool used for web automation, penetration testing, and credential stuffing (note: it is often misused for malicious purposes). Here are its main features:
Key Features of OpenBullet 2:
Multi-threaded engine – High-speed request processing with configurable thread limits.
Proxy support – HTTP, HTTPS, SOCKS4/5 proxies with rotation and banning of dead proxies.
Config system – Uses LoliScript (a custom scripting language) to define attack/request workflows.
Captcha solving – Integrates with services like 2Captcha, Anti-Captcha, and CapMonster.
Target management – Import/export proxies, wordlists, and combo lists (email:pass).
Hit logging – Automatically saves valid results (e.g., successful logins) with custom data extraction.
Custom parsers – Regex, JSON, and HTML parsing to extract tokens, CSRF, or other data.
Proxy scanner – Built-in tool to test and validate proxy quality.
Plugin system – Extend functionality with C# plugins.
REST API – Allows remote control and integration with other tools.
Database backend – Uses LiteDB or SQLite for storing configs, hits, and settings.
Dark theme UI – Modern, responsive interface (successor to the older OpenBullet 1.x).
Typical legitimate use cases:
Warning: Unauthorized use against websites you don't own is illegal in most jurisdictions (violates CFAA, Computer Misuse Act, etc.).

Understanding OpenBullet 2: A Comprehensive Guide to the Web Automation Suite
OpenBullet 2 is a powerful, cross-platform automation suite powered by .NET Core, designed for developers and security researchers. While it is widely recognized as a versatile tool for web scraping and automated penetration testing, its high level of customization has also made it a popular choice for more malicious activities, such as credential stuffing. Core Functionality and Features
OpenBullet 2 functions as a "middle-sophistication" automation tool that allows users to perform complex HTTP requests against target web applications. Its key capabilities include:
Data Scraping and Parsing: It can easily process HTML and JSON to transform received data into convenient formats for further analysis.
Built-in Data Management: After a process is complete, users can utilize internal tools to filter, sort, and remove duplicate data.
Customizable Configurations: Users can create "blueprints" or configs that define specific login URLs, parameter names, and success conditions for a target site.
Proxy Integration: To avoid detection or IP bans, the tool supports rotating proxies, including residential and datacenter options.
Advanced Solver Support: It can leverage third-party CAPTCHA solvers to bypass security challenges that would otherwise block automated bots. Getting Started with OpenBullet 2
The transition from the original OpenBullet to OpenBullet 2 introduced a web-based client, making it more accessible across different operating systems. Installation Basics
OpenBullet 2 can be installed on Windows, Linux, and macOS. For Windows users:
Getting to Know OpenBullet 2: Functionality, Interface, Settings
OpenBullet 2 is a cross-platform, open-source web testing and automation suite. While widely used for legitimate web scraping and API testing, it is also a popular tool for automated credential stuffing and account takeover attacks. Key Features
Multi-Platform Support: Built on .NET, it runs on Windows, Linux, and macOS.
Dual Interface: Includes both a web-based client and a native Windows-only client.
Customizable Configurations: Users can create "configs" using LoliCode or a visual editor to define how the bot interacts with a target site, including handling requests, parsing data, and solving CAPTCHAs.
Proxy & Wordlist Management: Supports multithreading and integrated proxy rotation (HTTP, HTTPS, SOCKS5) to bypass security measures and avoid IP bans. Getting Started "OpenBullet 2" is a security testing tool used
Download: Obtain the latest version from the OpenBullet 2 GitHub repository or the official documentation. Installation:
Ensure you have the required .NET Runtime and ASP.NET Core Runtime installed. Run the OpenBullet2.Web.exe file for the web client.
Access: Open your browser and navigate to http://localhost:5000 to access the dashboard. Safety & Legal Warning
OpenBullet 2 is powerful and can be used for illegal activities such as (D)DoS attacks or unauthorized credential testing. Always ensure you have explicit permission to test a target website, as unauthorized testing is illegal.
While there isn't a single "academic" white paper in the traditional peer-reviewed sense, there are several authoritative guides and technical overviews that function as "solid papers" for understanding OpenBullet 2

Below is an overview of its core architecture and functions, which can serve as a foundation for a technical or research paper.
OpenBullet 2 is an open-source web automation tool that allows users to perform requests toward a target web application. It features a flexible environment for creating "configs"—scripts that define how to interact with specific websites. While widely used for legitimate security auditing and data collection, it is also a popular choice for credential-stuffing attacks due to its high speed and extensive feature set. Core Components The Engine
: Built on .NET, it supports multi-threading, allowing for thousands of simultaneous requests. : These are the logic files (often using LoliScript
) that tell the software how to log in, solve CAPTCHAs, and parse data. You can find setup guides and config creation steps on platforms like Course Hero
: Supports various proxy types (HTTP, SOCKS4, SOCKS5) to bypass rate limits and IP-based blocking. User Interface
: Offers both a native CLI and a web-based UI, making it accessible from remote servers or local machines. Common Use Cases Security Auditing
: Checking for weak credentials or testing the resilience of login endpoints against automated attacks. Data Scraping
