Was wondering how so many people since I’ve never heard of Change Healthcare:

Change Healthcare is one of the largest handlers of health, medical data, and patient records, as it processes patient insurance and billing across the U.S. healthcare sector, including thousands of hospitals, pharmacies, and medical practices. As such, Change handles huge amounts of health and medical-related information on around a third of all Americans

And of course it some dumb shit like someone with privileged access who doesn't have two factor enabled.
