Hundreds of planned operations, outpatient appointments, and diagnostic procedures have been canceled at multiple hospitals in Lincolnshire, England, after a “major” computer virus compromised the National Health Service (NHS) network on Sunday. The incident took place after the U.S. and Canada issued a joint cyber alert, warning hospitals and other organizations against a surge in extortion attacks that infects computers with Ransomware that encrypts data and demand money for it to be unlocked. Since earlier this year, over a dozen hospitals have been targeted by ransomware, enforcing them to pay the ransom amount as per the demand.
