Block the mac addresses of your PS4's Wifi and Lan adapters on your router.
That way you have full network access between your home network and your PS4 but the PS4 can never connect to the internet.
Yeah that is what I do. I nearly removed it to use netflix, but I think that isn't working on 5.05 anymore anyway.
The media player is worse than movian and I never ftp into the ps4. So really the only thing making me connect the ps4 to the network at all is the exploit.
