 is the criminally fraudulent process of attempting to acquire sensitive information such as usernames, passwords and credit card details by masquerading as a trustworthy entity in an electronic communication.

The most common method of phishing is by sending misleading e-mails that point to web sites masquerading as legitimate account holding institutions.
