The Michigan Attorney General announced that Corewell Health suffered a data breach affecting Michigan residents.
The names, dates of birth, email addresses, phone numbers, medical diagnoses, health insurance information and Social Security numbers for about one million Corewell Health patients were compromised in the breach. In addition, the names, addresses and health insurance identification numbers of 2,500 users of the portal for Priority Health were also compromised, according to a statement from the health system earlier this month. In total, the breach affected nearly 8.5 people nationally.
