Abstract
In one embodiment, the present invention relates to a method and system for combating phishing. A computer receives an email comprising a sender email address and a link. The computer determines a sender domain name from the sender email address and ascertains a Uniform Resource Locator (URL) corresponding to the link. The computer then determines a link domain name from the URL. The computer then determines whether the sender domain name is different than the link domain name, so as to classify the URL as a potential phishing URL.
