Phishing is the practice of masquerading as a legitimate organization, such as an Internet service provider (ISP), bank, or online auction site, in order to acquire sensitive information including user names, passwords, and credit card numbers. Typically, phishing is carried out by an email or instant message directing you to enter your sensitive information at a fake website that appears nearly identical to a legitimate one.

Safari helps to protect you from fraudulent Internet sites. When you visit a suspicious site, Safari warns you and prevents the page from loading. To take advantage of this protection, be sure to keep the “Warn when visiting a fraudulent website” checkbox selected in the Security pane of Safari preferences.
