PS4 game installed by itself?

Yesterday I got a constant notification that Assassin's Creed Odyssey was being installed, but I didn't see anything and then in the evening that it was installed. So I have it in my game library and can use it.

I didn't buy the game or even looked at it in the store and generally I haven't been in the store.

It installed itself all by itself. Maybe I was hacked or what is going on?

You haven't been hacked, hacking is different

But what was it then?

Sounds good. Why doesn't this happen to me? Did you buy that

No, not bought 😅

Haha 😂. Cool
