Anti-Fraud and Geo-Blocking Bypass System
Budget: ₹1,250 – ₹2,500 INR
We require a highly skilled developer to design and deploy a multi-layered, stealth-focused system to bypass advanced geo-blocking and anti-fraud detection mechanisms. The solution must combine network obfuscation, browser fingerprint spoofing, and behavioral automation to mimic legitimate human interactions while avoiding detection.
Core Requirements
1. Infrastructure Setup
Residential Proxies with Automated IP Rotation:
Integrate rotating residential proxies (e.g., Bright Data, Oxylabs) via API to cycle IPs per request/session.
Implement sticky sessions for consistency during logins or stateful interactions.
Multi-Hop SSH Tunneling:
Configure OpenSSH with ProxyJump or netcat to chain connections through 3+ global VPS nodes (e.g., Germany → Singapore → USA).
Ensure traffic is encrypted and routed through non-blacklisted IPs.
Traffic Obfuscation:
Deploy V2Ray with XTLS/Reality Protocol or Shadowsocks with obfs4/SimpleTLS plugins to mask traffic as standard HTTPS.
Bypass Deep Packet Inspection (DPI) by mimicking legitimate TLS handshakes.
2. Browser Anonymization & Fingerprint Spoofing
Chromium/Puppeteer Configuration:
Use Puppeteer-extra with Stealth Plugin to randomize browser fingerprints (canvas, WebGL, fonts, user-agent).
Disable WebRTC leaks and spoof timezone/language settings to match proxy geolocation.
Human-Like Behavioral Automation:
Script randomized mouse movements, keystrokes, and scroll speeds (Selenium/Puppeteer).
Introduce delays (2–10s) between actions to avoid bot-like patterns.
3. DNS & Geolocation Privacy
Encrypted DNS: Configure dnscrypt-proxy with DNS-over-HTTPS (Cloudflare/Quad9) to prevent DNS leaks.
Geolocation Spoofing: Override HTML5 geolocation APIs using browser automation (e.g., geolocation.override) or virtual GPS tools.
4. Traffic Routing & Testing
Proxychains Integration: Route all traffic through the SSH + proxy tunnel on Linux.
Leak Testing:
Validate system against IP/DNS/WebRTC leaks using tools like browserleaks.com, IPHub, and Wireshark.
Ensure zero correlation between real location and spoofed footprint.
Deliverables
A fully automated system integrating the above components.
Scripts for IP rotation, browser fingerprint randomization, and behavioral automation.
Documentation covering:
Setup/installation steps.
Maintenance protocols (proxy rotation, SSH tunnel updates).
Troubleshooting leaks or detection flags.
Post-deployment testing results proving evasion of anti-fraud systems (e.g., PerimeterX, DataDome).Required Skills
Expertise in networking (SSH tunneling, SOCKS5, DNS-over-HTTPS).
Proficiency with Puppeteer, Selenium, and browser DevTools for fingerprint spoofing.
Experience with V2Ray/Shadowsocks configurations and traffic obfuscation.
Familiarity with residential proxy APIs and IP rotation strategies.
Knowledge of anti-fraud systems (e.g., device fingerprinting, behavioral analytics).tools should or can include credential stuffing or brute-forcing, Keywords: SSH tunneling, residential proxies, V2Ray, Puppeteer-stealth, fingerprint spoofing, DNS-over-HTTPS, IP rotation, anti-fraud evasion.
