Pharming Overview
Pharming is the exploitation of vulnerability in Domain Name Service (DNS) server software that allows a hacker to redirect that website's traffic to another web site. DNS servers are the machines responsible for resolving Internet names into their real addresses, and are used anytime a user types the name of a website into his or her web browser and attempts to view a web page. Pharming attacks can be more lethal than conventional webpage based phishing attack since the real domain name for the organization is redirected to fraudulent pages.
