I do doubt it as well, I do not believe it, but lets assume for a moment that it is true, even in that case they have nothing to worry about because they will catch the hackers one way or another. You could hide in china or russia, and you would still be caught and nothing will save you. So these hackers messed with the wrong powerful group, and I think even if they do get paid eventually, they will realize that the money is not spendable at all. This is going to be a great story to follow to see how it unfolds, but I will probably forget about it by tomorrow, too many things happens in the world every day.
