Phishing is a type of attack wherein the attacker impersonates a valid site and steals sensitive information entered by the customer on the fake site.

The attacker sends the victim a forged e-mail having the link of a fake page. The fake page looks exactly like a valid page of the original site. These e-mails have upsetting or exciting (but false) statements to get the customer to react immediately. When the customer clicks the link, he is asked to provide his credentials to login and update his personal information. This reveals important information to the attackers.
