Fwitter is a Twitter-like social media application built with React and FaunaDB. It functions as a single-page application where the frontend communicates directly with FaunaDB for all data operations, authentication, and authorization. The architecture uses React hooks for state management, React Router for navigation, and FaunaDB's User Defined Functions (UDFs) encapsulated in a query manager layer to handle data interactions securely. Key features include user registration/login, posting text/media content, liking/commenting/refweeting, following users, and searching by tags or usernames. The application demonstrates FaunaDB's capabilities for building serverless applications with fine-grained access control through roles and UDFs.
This repository serves as a technical deep-dive into Google's reCAPTCHA system, particularly focusing on its obfuscation techniques, fingerprinting mechanisms, and anti-tampering measures. It includes extracted JavaScript snippets that implement specific browser fingerprinting signals (e.g., storage access checks, window opener properties, WebGL data extraction) and JSON files containing example fingerprint data. The repository also contains analysis of the now-removed BotGuard component, including its obfuscated virtual machine implementations. While the subject matter is largely historical due to the removal of BotGuard in April 2026, the repository provides valuable insights into the techniques used by advanced anti-bot systems.
