One Medical Senior Health, formerly known as Iora Health, has disclosed a data breach affecting archived patient records. On June 13, the Amazon-owned company learned that an unauthorized person had gained access to a third-party file storage system used to retain archived information from Iora Health, which One Medical acquired in 2021.

What Data Was Accessed

The investigation into the One Medical data breach determined that certain patient files related to a limited number of legacy Iora Health and One Medical Seniors patients were accessed. The announcement said no other One Medical patients were impacted by the intrusion. 

The healthcare company emphasized that the incident was isolated to the third-party file storage system and that no other One Medical or Amazon systems were affected.
