WannaCry spreads across local networks and the Internet to systems that have not been updated with recent security updates, to directly infect any exposed systems. A "critical" patch had been issued by Microsoft on 14 March 2017 to remove the underlying vulnerability for supported systems, nearly two months before the attack, but many organizations had not yet applied it. Those still running exposed older, unsupported op
