EA releases Title Update 6. This update invalidates every exploit found so far. It introduces "key segmentation," where different game archives (faces, stadiums, databases) use different derived keys from a master key. In effect, finding one key no longer unlocks the entire game.
Unlike previous titles where the key was static and could be extracted via a debugger, the FIFA 20 encryption key was dynamic. It would de-encrypt assets on the fly, only in memory, and only when the official EA executable was running and authenticated with EA’s servers.
For previous FIFA titles (FIFA 15, 16, 17, 18, 19), the game archives (typically .big files) were encrypted, but the keys were either discovered by modders or reverse-engineered from the game’s executable. This allowed the community to create massive patches: new stadiums, real advertising boards, updated kits, licensed scoreboards, and even entirely new leagues.
