You recognize the original page by it’s address. For example, the internet address for your e-mail at Yahoo is "mail.yahoo.com" and the phishing pages for your e-mail at yahoo will be very different, like "abc.phishhhhhhh.com". Phishing pages are used so that you will type in your login name and password. Your data are then recorded.
