An attacker modifies a public DNS cache to cause certain names to resolve
						to incorrect addresses that the attacker specifies. The result is that
						client applications that rely upon the targeted cache for domain name
						resolution will be directed not to the actual address of the specified
						domain name but to some other address. Attackers can use this to herd
						clients to sites that install malware on the victim's computer or to
						masquerade as part of a Pharming attack.
