There are known knowns. These are things we know that we know. There are known unknowns. That is to say, there are things that we know we don't know. But there are also unknown unknowns. There are things we don't know we don't know.

We know a promotion is on the line. We know that, like it or not, this is a fairly standard BI piece of info in order to not render false positives. We know said info is easily had with a few combos of resources and a few bucks. We know we don't know if OP's ssn is out there already (highly likely if he has done anything within the market -- those places are a more likely target for the # to make it to the criminal element). We don't know what else we don't know, which at least is a negative known. ( I know, I know).
