An attacker exploits characteristics of the infrastructure of a network
						entity in order to perpetrate attacks or information gathering on network
						objects or effect a change in the ordinary information flow between network
						objects. Most often, this involves manipulation of the routing of network
						messages so, instead of arriving at their proper destination, they are
						directed towards an entity of the attacker's choosing, usually a server
						controlled by the attacker. The victim is often unaware that their messages
						are not being processed correctly. For example, a targeted client may
						believe they are connecting to their own bank but, in fact, be connecting to
						a Pharming site controlled by the attacker which then collects the user's
						login information in order to hijack the actual bank account.
