Blocks emails that contain links in the message body pointing to known phishing sites or if they contain typical phishing keywords. Phishing is an email based social engineering technique aimed at having email users disclose personal details to spammers. A phishing email is most likely crafted to resemble an official email originating from a reputable business, for example a bank. Phishing emails will usually contain instructions requiring users to reconfirm sensitive information such as online banking details or credit card information. Phishing emails usually include a phishing Uniform Resource Identifier (URI) that the user is supposed to follow to key in some sensitive information on a phishing site. The site pointed to by the phishing URI might be a replica of an official site, but in reality it is controlled by whoever sent the phishing emails. When the user enters the sensitive information on the phishing site, the data is collected and used, for example, to withdraw money from bank accounts.
The Anti-Phishing filter detects phishing emails by comparing URIs present in the email to a database of URIs known to be used in phishing attacks. Phishing also looks for typical phishing keywords in the URIs.
The Anti-Phishing filter is enabled by default on installation.
