Pharming

The term pharming refers to a practice where perpetrators redirect users from legitimate Web sites to fraudulent Web sites. This is done by exploiting weaknesses in Domain Name Service (DNS) software, which is used to resolve Internet names with the corresponding Internet Protocol (IP) address. For example, when a user enters http://www.mybank.com, DNS software resolves that name with an IP address that consists of a series of numbers, such as 201.26.156.98. When pharming has occurred with respect to that Internet name, the DNS software sends users to another IP address that does not belong to the actual business.
