Cyberattack on N.L. Healthcare System Possibly Worst In Canadian History

May 28, 2022


Thousands of Newfoundland and Labrador residents had appointments cancelled as a result of the attack, ranging from blood work to cancer care. Patient and employee information has been stolen from three out of the four regional health authorities. System had to be rebuild from scratch taking over a month. Sources say ransom was paid, but decryption key did not work. Later reports indicated 200,000 patient and employee files were taken from a network drive.

UPDATE: July 2022: Newfoundland and Labrador's largest health authority has notified 37,800 people that their privacy was breached as part of last fall's devastating cyberattack.
