Secure Electronic Mail
All it takes is an e-mail addressed to you that contains a link; once you follow the link, you may have given control of your email account to someone else.

Here is a very easy way to test for this vulnerability:
Simply open your web based email account and read any of your messages.

Highlight the URL (this is the address and will look like the one above) and copy or write this information down.
Go to another computer (or email a trusted friend the URL) and open the browser.

Paste the copied text into the URL and press enter

You are done. You should NOT be able to see your message and should receive a message asking you to log in or that your session expired.

If you did see your message, then you may be vulnerable. Notify your e-mail service provider and DO NOT click on any e-mail links; instead, copy and paste the link into your browser. Should you find an e-mail system that is not secure, please contact the owner of that system and let them know as soon as possible.
