U.S., Canada issue joint alert on ‘ransomware’ after hospital attacks

The United States and Canada on Thursday issued a rare joint cyber alert, warning against a recent surge in extortion attacks that infect computers with viruses known as “ransomware,” which encrypt data and demand payments for it to be unlocked. The warning follows reports from several private security firms that they expect the crisis to worsen, because hackers are getting more sophisticated and few businesses have adopted proper security measures to thwart such attacks. “Infections can be devastating to an individual or organization, and recovery can be a difficult process that may require the services of a reputable data recovery specialist,” the two governments said in the alert, distributed by the U.S. Department of Homeland Security and the Canadian Cyber Incident Response Centre.
