PS4 is not hacked (as far as I know) - The COD Loadout system is flawed and supports hackers. Put simply the Loadout (Which is stored on Activision Servers) says what guns perks etc are selected in it. It also has debug features such as wall hack, no clipping, and god mode which can be activated within the Loadout (Just no via the standard interface. BTW this is not new to Ghosts it is in Mw2 and Mw3.
Hackers hack these loadouts on Jailbroken PS3s turning on all perks, mini gun as secondary weapon and debug features then use the same PSN account on PS4 which uses the same loadout from PS3. This brings all the hacks (Debug features) across to PS4.
HMMM. With out defending any one but... let me point out a few things for you...
 THE WHOLE WORLD IS IN CRISIS, over five countries have become bankrupted and they ALL fought in this war that you refer too.
 Please do not single out people or countries without 100% proof off your statements
 What this got to with gaming?
 I'm also from the OP's generation....wanna take a pop at me!!! ohh, I'm from Ireland, is this ok with you.
I have read this thread and since we all agree there are cheaters and hackers on ps4 , the question now is what does activision , infinityward , and treyarch plan to do about it ? There has to be something they can do about this , maybe they can fix match making in ghosts so that non cheaters always play together and cheaters only play against other cheaters and hackers? I am just tossing idea's around but this would be cool right ?
The fix for Loadout hacking is really simple for PS4.
A loadout is applied when the player spawns. So as that loadout is being applied check it for inconsistencies such as God mode or mini gun as secondary.
If the game spots inconsistencies then reset the loadout to a default loadout. You don't even need to ban the player (Unlikely but there is a possibility that player had a hack pushed onto their account) just stop the cheating.
