A settlement has been reached with McKenzie Memorial Hospital d/b/a McKenzie Health System (“McKenzie” or “Defendant”) in a class action lawsuit. This case is about the targeted cyberattack on McKenzie's computer systems that occurred in April 2025 (the “Data Incident”). Certain files that contained private information were accessed. These files may have contained personal information such as name; address, date of birth; Social Security number; patient account number; medical record number; diagnosis and treatment information; contact information; and demographic information.
The lawsuit is called In Re: McKenzie Memorial Hospital d/b/a McKenzie Health System 2025 Data Breach Litigation, Case No. 2025-40999-CZ. It is pending in the Circuit Court for Sanilac County, Michigan (the “Litigation”). McKenzie denies that it did anything wrong, and the Court has not decided who is right. The parties have agreed to settle the lawsuit (the “Settlement”) to avoid the costs and risks, disruptions, and uncertainties of continuing the Litigation.
