A $480-million class-action suit has been filed in a Sarnia court against five regional hospitals and IT provider TransForm Shared Service in relation to the Oct. 23 cyberattack.
Chatham-Kent Health Alliance, Bluewater Health, Windsor Regional Hospital, Hotel-Dieu Grace Healthcare and Erie Shores HealthCare are named in the document filed by Sarnia resident Robert Smith.
The document states that Smith has been a patient at Bluewater Health over the course of his life.
In a joint media statement, the hospitals and TransForm said they are “in receipt” of a lawsuit related to the attack.
Because the matter is before the court, none of the affected parties will be making any further comment about it.
According to the lawsuit, the ransomware attack breached the personal information of some 267,000 people.
The CBC has reported the cybercriminal group Daixin has claimed responsibility for the attack and has published some of the stolen data on the dark web.
The hospitals did not pay a ransom.
