5.1.3 Using the @ Symbol to Confuse
When the @ symbol is used in an “http://” or “https://” URL, all text that was entered before the @ symbol is ignored and the browser references only the information that has been entered after the @ symbol. This trick was being used by hackers for fooling the person viewing the email code into thinking the link is going to the site listed before the @ symbol, while it actually links to the hackers site after the @ symbol. However, this text before the @ symbol is ignored and the link sends the user to “210.93.131.250/my/index.htm”.
