McLaren HealthCare reports ransomware attack

One of Michigan's largest healthcare systems, McLaren HealthCare, has confirmed that it is currently grappling with a ransomware attack, following claims made by a well-known hacker gang AlphV.

The organization detected suspicious activity on its computer network, with outages that affected billing and electronic health record systems. The situation escalated to the point where the computer network had to be shut down at 14 different facilities, compelling employees to resort to personal phones for communication.

McLaren HealthCare has enlisted leading global cybersecurity specialists to aid in the investigation and has been in contact with law enforcement. They have taken measures to strengthen their cybersecurity posture, emphasizing their commitment to securing systems and minimizing disruption to patients and communities they serve.

No details are published about the exposed data nor the number of affected individuals.

Subsequently, McLaren HealthCare are looking into reports suggesting that some of their data might be available on the dark web. They assured that affected individuals would be notified as soon as possible.

Update - The AlphV ransomware gang has added McLaren Health Care to the list of victims on its site. The group claims to have stolen data belonging to 2.5 million of McLaren Health Care patients.

“It would have been more interesting if a Mclaren representative had talked in an interview about how they asked not to publish the stolen data and skillfully wanted to cover up the fact that their network had been hacked. Mclaren were preparing a way out and ended up devaluing the sensitive data of 2.5 million of their patients. Protecting the privacy and interests of your customers is nothing more than lip service." is part of the message published by the ALPHV gang on its leak site.
