  3. Phishing Attack Stages • The attacker obtains E-mail addresses for the intended victims. These could be guessed or obtained from a variety of sources. • The attacker generates an E-mail that appears legitimate and requests the recipient to perform some action. • The attacker sends the E-mail to the intended victims in a way that appears legitimate and obscures the true source. • Depending on the content of the E-mail, the recipient opens a malicious attachment,completes a form, or visits a web site. • The attacker harvests the victim’s sensitive information and may exploit it in the future.
