This project provides an AI-powered skill for advanced JavaScript reverse engineering and anti-bot bypass, targeting web security researchers and developers. It streamlines the complex process of analyzing obfuscated code, restoring encryption algorithms, and simulating network requests, ultimately enabling automated interaction with protected web services.

How It Works

The core approach employs a unified workflow centered around the camoufox-reverse anti-detection browser. This C++ engine handles network capture, source code localization, debugging, and crucial anti-detection verification. Following initial analysis, the skill leverages Node.js (using crypto, crypto-js) or Python (using hashlib, pycryptodome) for precise algorithm restoration and automated request simulation, offering a robust solution for tackling sophisticated anti-bot mechanisms.

Highlighted Details

• Dual-Language Algorithm Restoration: Implements common cryptographic algorithms (MD5, SHA, AES, DES, RSA, HMAC, Base64) in both Node.js and Python.
• Advanced Obfuscation & VM Analysis: Provides strategies for OB obfuscation, control flow flattening, eval packing, and JSVMP analysis via Hooking, instrumentation, and logging.
• Camoufox Anti-Detection: Utilizes a C++ engine for advanced browser fingerprint spoofing to bypass protections like Cloudflare, RS, and JY.
• Unified MCP Workflow: Integrates with the camoufox-reverse MCP server, offering 32 core tools for tasks including source-level instrumentation, network interception, and environment comparison.
• Cookie Attribution: Differentiates between Set-Cookie and document.cookie to pinpoint cookie origins.
• WASM & Protocol Handling: Supports reverse engineering of WebAssembly modules and countermeasures against TLS fingerprinting and HTTP/2 enforcement.
