    It said some records also included encrypted payment
    card information, but it could not rule out the
    possibility that the encryption keys had also been
    stolen.

Why did the world end up with a pull-system for payments? Why do I have to give out my credit card number and enable the other side to pull arbitrary amounts as often as they like?

This is one of several things crypto currencies got right. You pay by pushing money to the other side.
