Abstract
Hospitals and health care systems have become a major target for hackers. In September, the computer systems of three Ontario hospitals were crippled by a ransomware virus, an attack in which hackers encrypt data and demand payment to unlock it. Although the attack did not lead to any patient information leaving the hospital's system, nor any payment to the hackers, the effect on hospital operations was severe. [Extracted from the article]
