@Commswonk -- Re: What Exactly Was The Breach ???
It's almost guaranteed that they have a file on you. Credit card, bank account number or at least verification of an account, insurance (car and home), any utilities, employment (and places you applied for employment) and the list goes on and on. Last time I checked the Big 3 here in the States, I was surprised at what they had. They knew more about me than I knew about me.
As the article states, just about every company share info back with them.
