The Record reports:
Ransomware hackers stole the Social Security numbers and health insurance information for more than 740,000 people during an attack on a prominent Michigan hospital network.
McLaren Health Care filed documents on Friday concerning a ransomware attack that took place in August 2024 — the second cyber incident to impact the healthcare giant in 12 months.

The ransomware attack appeared to have been the work of the INC Ransom group. A copy of their ransom note, shared on x.com (formerly Twitter) indicated that the attackers had encrypted McLaren’s systems and were demanding payment for a decryptor and to delete stolen data.
McLaren’s notification letter does not reveal whether the healthcare system paid any ransom demand.
