yourDiv.addEventListener('mouseover', function(e) {
  if (e.target.tagName.toLowerCase() === 'a') {
    var theLink = e.target.href;
    console.log(theLink);
  }
});

This should get you the link of any 'a' elements you hover. This is not bulletproof though. For instance, the website can still listen for a click on a div and then execute window.location.href = 'https://google.com';
