Warn when visiting a fraudulent website
Safari warns you if the site you’re visiting is a suspected phishing website. Phishing is a fraudulent attempt to steal your personal information, such as usernames, passwords and other account information. A fraudulent website masquerades as a legitimate one, such as a bank, financial institution or email service provider. Before you visit a website, Safari may send information calculated from the website address to Google Safe Browsing to check if the website is fraudulent. If you have China mainland set as your region in the Language & Region pane of System Preferences, Safari may also use Tencent Safe Browsing to do this check. The actual website address is never shared with the safe browsing provider. These safe browsing providers may also log your IP address when information is sent to them.
