Arietis Health, LLC (“Arietis Health”) provides healthcare billing services to NorthStar Anesthesia, which manages healthcare entities that provide anesthesia and pain management services (the “Healthcare Entities”). Arietis Health determined that information belonging to certain patients of those Healthcare Entities, which it received in connection with the billing services it provides, may have been involved in a data security incident. The Healthcare Entities whose patient information may have been involved in the incident are listed below. On September 29, 2023, Arietis Health began notifying potentially impacted individuals.

On May 31, 2023, Progress Software – the company responsible for MOVEit file transfer software – alerted Arietis Health to a critical vulnerability affecting MOVEit, a solution used widely by businesses and government agencies, including Arietis Health, to securely transfer data. After becoming aware of the alert, Arietis Health took immediate steps to secure and patch its MOVEit server in accordance with Progress Software’s instructions. Arietis Health thereafter engaged leading, independent cybersecurity experts to conduct a comprehensive investigation. On July 26, 2023, the investigation determined that unauthorized actors had access to Arietis Health’s MOVEit server on May 31, 2023, and may have acquired certain files which contained data belonging to patients of the Healthcare Entities. On August 3, 2023, Arietis Health informed NorthStar Anesthesia of the incident, and reviewed the impacted data to determine what information may have been involved in the incident.
