Since the end of October, a cyberattack on the health-care system in Newfoundland and Labrador has caused thousands of delays and cancellations for services.

Patients have missed appointments and procedures, including chemotherapy. With their IT networks knocked out, facilities resorted to pen and paper. The CEO of a cybersecurity firm in Fredericton, David Shipley, called it “the worst cyberattack in Canadian history.”

Disruptions to health services are easing. But while the province has now confirmed that both patient and employee data was stolen, it is still offering little information on the attack. Today on Front Burner, St. John’s-based CBC reporter Peter Cowan joins us to explain what this attack was, why the province isn’t saying more, and why health breaches like this are happening so often.
