Requirements Document: WeChat Mini Program Protocol-Level Auto-Purchasing (Sniping) Tool Development 1. Project Overview The objective of this project is to develop an automated purchasing tool based on the protocol layer (implemented in Python or Go). This tool must bypass the mini program's front-end UI by reverse-engineering its core business logic and API interfaces. It will directly construct underlying network requests (HTTP/HTTPS) to achieve millisecond-level automated purchasing and order placement. 2. Core Technical Requirements Platform Environment: WeChat Mini Program (iOS/Android or PC WeChat client). Development Language: Python 3.10+ or Go 1.20+. Reverse Engineering Capabilities: Must possess the ability to decompile mini program packages (.wxapkg), analyze obfuscated JavaScript logic, and extract encryption algorithms (e.g., MD5/AES/RSA). Packet Capture & Decryption: Must be able to bypass HTTPS restrictions, handle SSL Pinning mechanisms, and capture plaintext requests/responses between the mini program and the server. Protocol Simulation: Fully simulate the acquisition of the WeChat login state, Token maintenance, and various Header parameters required during order placement (e.g., User-Agent, Referer, X-Sign). 3. Functional Requirements List A. Interface Reverse Engineering & Analysis Login Module: Simulate the WeChat [login to view URL] process to exchange the code for the business-side token or session_id. Parameter Decryption: Reverse-engineer dynamically changing encrypted parameters within the order request (e.g., timestamp salts, signature validation sign, and encrypted data payloads). Path Restoration: Identify the core purchasing endpoints (Check-in, Add-to-cart, Submit-order). B. Auto-Purchasing Logic Implementation Precise Timing: Support NTP network time synchronization to trigger requests at the millisecond (ms) level. Concurrency Control: Support multi-threading or Coroutines (Goroutines) for high-frequency requests to respond to inventory refreshes. Inventory Monitoring: Monitor product status in real-time and trigger order placement the exact moment it changes to "Available for sale." C. Bypassing & Anti-Risk Control Certificate Injection: Provide a solution to bypass certificate validation in specific environments (such as Rooted/Jailbroken devices or emulators). Risk Control Bypass: Provide reserved interfaces or integrate third-party captcha-solving platforms to handle risk control measures triggered during order placement, such as image captchas or sliders. 4. Deliverables Requirements Complete Source Code: Must include the core reverse engineering logic and the recreated encryption algorithm code. Environment Setup Guide: Instructions on how to configure the packet capture environment (e.g., using Charles/Fiddler + HttpCanary/Frida). Configuration Files: Allow users to customize settings such as the purchase execution time, product ID, Token information, concurrency limits, etc. Technical Documentation: A brief explanation of the API encryption logic and the method used to maintain the login state. 5. Developer Capability Evaluation Metrics (Suggested Interview Questions) "How do you handle header signature encryption for Request APIs within a WeChat Mini Program?" "For mini programs that have SSL Pinning enabled, what are your standard unpacking and packet capture solutions?" "If the target mini program utilizes WeChat native plugins or highly obfuscated JS code, how do you locate the exact order placement logic?"

Hello, This is a very interesting project and I'd like to take part. I'm very experienced in reverse engineering Android apps specifically, and I believe I can offer great services. I've already installed Wechat app and performed an initial analysis. I haven't found any advanced protection mechanisms (packers) yet, and the code (Java and C) is not obfuscated. However the code base is large and it makes heavy use of C libs. As you may know, this will be a difficult and time-consuming project, which will cost much more than your proposed budget. That's why I propose we split it in $500 milestones, each one for every major task. Hope to hear from you soon. Thanks!

I’d approach this by using official APIs or approved partner interfaces where available, then build a fast monitoring and purchase orchestration service with token handling, config management, concurrency control, logging, and clear deployment docs. I’ve worked on similar commerce automation and monitoring projects where the goal was speed, reliability, and maintainability without brittle reverse engineering or risky bypass methods. Your real goal is a dependable auto purchasing workflow that is fast, configurable, and safe to run in production over time. So, I'll: Design the compliant architecture around approved APIs, authentication flow, monitoring, and order submission. Build the automation service, config system, logging, timing controls, and deployment guide. Deliver source code, documentation, and a tested setup ready for VPS or server use. Best, Siva

✅Hello, I’ve reviewed your requirements and understand you want a high-speed, protocol-level automation system that interacts directly with a mini-program’s APIs, including timing, concurrency, and dynamic parameter handling. That said, parts of the request (bypassing SSL pinning, decrypting protected logic, and evading risk controls/captchas) conflict with platform terms and security policies. I don’t build tools that circumvent safeguards or enable unfair purchasing advantages. What I can deliver—reliably and professionally—is a compliant, high-performance automation layer using documented or permitted endpoints: • Robust request engine (Python/Go) with async concurrency and ms-level scheduling • Token/session lifecycle handling and header management • Real-time inventory polling with adaptive throttling • Clean, well-documented code + demo page + config system • Load-testing and performance validation (50+ FPS equivalent throughput targets) I’ve built similar high-throughput systems (event-driven polling, queue-based workers, and API orchestration) that prioritize stability, observability, and maintainability. I can provide a PoC quickly and iterate based on your flow and constraints. If you’re open to a compliant, production-safe implementation, I’d be glad to collaborate.
