bt4-final.iso | ettercap [PERFORMANCE]

Have ARP and DNS spoofing attacks become really outdated, or do they rely on the vulnerability of the actual webpages visited by the target hosts' web browser and their susceptibility to xss scripts (or whatever the ettercap filter uses for an injection technique)? I have just noticed that redirecting RHOSTs has become harder and harder... Anyone else notice? Anyone know of a good source for obtaining open source/bleeding edge ettercap filters :) I can never get my VM-Targets to redirect, and I even downgraded one XP test VM to SP2 and still nothing, arghhh!
