Phishing is a new type of network attack in which the attacker creates a replica of an existing Web page to trick users (for example, through specially crafted e-mail or instant messages) to send personal, financial, or password to what they believe is your service provides' Website. In this research we proposed a new anti-phishing algorithm based on the final host, called Link Guard, using the generic characteristics of hyperlinks in phishing attacks. These characteristics are derived by analyzing the phishing data file provided by the Anti-Phishing Working Group (APWG). Because it is based on the generic characteristics of phishing attacks, Link Guard can detect phishing attacks that are not only known but also unknown.
