The covered entity (CE), University of Michigan/Michigan Medicine, reported that several employees were the subjects of an email phishing scheme that affected the protected health information (PHI) of 33,857 individuals. The PHI involved included names, addresses, dates of birth, Social Security Numbers, health insurance and claims information, diagnoses, lab results, medications, and other treatment information. The CE notified HHS, the affected individuals, the media, and provided substitute notice. In its mitigation efforts, the CE implemented additional administrative, technical, and security safeguards to better protect its PHI. Staff were retrained on email security precautions.
