They didn't lose them. They still have them. They just let someone else make a copy. That didn't make the copy that Equifax still has any less valuable. Keeping that data secret isn't the only job it has. In fact that isn't even really their primary job. Their primary job is evaluating the credit worthiness of potential customers for equifax clients. As far as I know, they are still doing that job quite well.
