There are lots of companies in this space. If the big ones don't, there is a smaller, creepier one or a subsidiary that does.
As an example, One firm managed to figure out the correct expected birthdate of our child. The only record of this child are the medical and prescription records of the near fatal miscarriage that my wife was hospitalized for at 9 weeks.
If they can get that, one or more somebodies is paying off your company's payroll processor for your salary data.
The child was never born. The only records are “anonymous” by HIPPA standards data that the hospital or insurance co likely sells or shares with 3rd parties who can match a hospital admission to our mailing address.
