The message bespeak showed up in my twitter notifications: hi There! =B i see you get some experience in getting the redress sum of attention for medicaid related data leaks. i get found admin credentials to some super sensitive medical billing processing system and receive nothing but silence on all available touch channels and no action for months. The sender, who calls himself @SchizoDuckie on Twitter, turned out to live Jelle Ursem, an ethical researcher from the Netherlands who had previously found other leaks on GitHub that he responsibly disclosed. So now, two months later, we are pleased to part you with some of his findings concerning leaks of protected health information on GitHub, and our adventures — and misadventures — in trying to get entities to answer to our attempts at responsible disclosure. In this report, you will read about 9 U.S. entities’ leaks of PHI: Xybion, MedPro Billing, Texas physician house Calls, VirMedica, MaineCare, Waystar, Shields health care Group, AccQData, and single entity that we are not naming at the present time but are describing. For the 9 leaks, there were approximately 150,000 – 200,000 unique patients’ records exposed, and possibly many, many more, because Ursem did not sample or access everything that was exposed. You will also read about a developer we consider of as the “Typhoid Mary of Data Leaks.” We also point out certain common factors that contributed to the leaks and urinate recommendations for preventing them. Great thanks to Gertrude Lok of 6500�Kelvin.nl for graciously donating her design skills to this project. show or Download: “No need to cut When It’s Leaking” by Jelle Ursem in collaboration with DataBreaches.net (pdf, 35 pp)
