Auto Proxy & Fingerprint Spoofing System

Auto Proxy Assignment & Fingerprint Spoofing System

Automatic proxy assignment and fingerprint spoofing for all website visitors

Disclaimer: This is for educational purposes only. Implementing such systems may violate terms of service, privacy laws, and ethical guidelines. Always obtain proper authorization before implementing on any website.

System Overview

Visitor

User accesses your website

↓

Auto Proxy Assignment

System automatically assigns a residential proxy

↓

Website with Spoofed Identity

All requests appear to come from proxy location

↓

Google Analytics

Sees traffic from proxy location with spoofed fingerprint

This system automatically assigns a residential proxy to each visitor and spoofs their fingerprint including User-Agent, timezone, and other identifying characteristics.

Implementation Methods

Server-Side Implementation

Using a reverse proxy server to handle all requests

// Example Node.js reverse proxy with auto proxy assignment
const express = require(‘express’);
const { createProxyMiddleware } = require(‘http-proxy-middleware’);
const proxyChain = require(‘proxy-chain’);

const app = express();

// Pool of residential proxies
const proxyPool = [
    ‘http://proxy1:port’,
    ‘http://proxy2:port’,
    ‘http://proxy3:port’
];

// Middleware to assign proxy based on visitor
app.use((req, res, next) => {
    const userIp = req.ip;
    const proxy = assignProxy(userIp); // Get proxy based on user IP
    
    req.proxy = proxy;
    next();
});

// Proxy middleware
app.use(‘/’, createProxyMiddleware({
    target: ‘https://your-website.com’,
    changeOrigin: true,
    router: (req) => {
        return req.proxy; // Use assigned proxy
    },
    onProxyReq: (proxyReq, req, res) => {
        // Spoof headers and fingerprint
        proxyReq.setHeader(‘User-Agent’, getRandomUserAgent());
        proxyReq.setHeader(‘X-Forwarded-For’, getSpoofedIp());
        // Additional header manipulation
    }
}));

function assignProxy(ip) {
    // Simple hash-based proxy assignment
    const index = hashString(ip) % proxyPool.length;
    return proxyPool[index];
}

app.listen(3000, () => {
    console.log(‘Reverse proxy server running on port 3000’);
});
                    

Client-Side Implementation

Using JavaScript to route traffic through proxies

// Client-side proxy assignment (less reliable)
document.addEventListener(‘DOMContentLoaded’, function() {
    // Assign proxy based on visitor characteristics
    const proxyConfig = assignProxyConfig();
    
    // Override browser properties
    overrideFingerprint(proxyConfig);
    
    // Route requests through proxy
    if (proxyConfig.useProxy) {
        routeRequestsThroughProxy(proxyConfig.proxyUrl);
    }
});

function assignProxyConfig() {
    // Get visitor’s IP and characteristics
    const visitorId = generateVisitorId();
    
    // Return proxy configuration based on visitor
    return {
        proxyUrl: getProxyFromPool(visitorId),
        userAgent: getRandomUserAgent(),
        timezone: getRandomTimezone(),
        // Additional spoofing parameters
    };
}

function overrideFingerprint(config) {
    // Override navigator properties
    Object.defineProperty(navigator, ‘userAgent’, {
        value: config.userAgent,
        writable: false
    });
    
    // Override timezone
    Object.defineProperty(Intl.DateTimeFormat.prototype, ‘resolvedOptions’, {
        value: function() {
            const result = originalResolvedOptions.apply(this, arguments);
            result.timeZone = config.timezone;
            return result;
        }
    });
    
    // Additional fingerprint spoofing
}
                    

Note: Client-side fingerprint spoofing is limited and can be detected. Server-side implementation is more reliable but requires more technical expertise.
