Its a fear we all have. Receiving a notice that your social security number, medical records and other personal information could land in the wrong hands.

Thousands of patients from Sparrow Hospital and McLaren Greater Lansing received such notices from Wolverine Solutions Group.

WSG handles the hospitals billing, and they were the victim of a ransomware attack in September.

The company says there is no evidence that the attackers were able to get anyones personal information. Everyone who could have been impacted has been notified through a personal letter.

The attack is still under FBI investigation.
