What Does WannaCry Mean?
WannaCry is a type of ransomware attack that developed in the spring of 2017 and brought the idea of ransomware threats further into the mainstream. This global attack disabled many systems, including public-service systems such as those supporting hospitals and law-enforcement offices. Experts classified WannaCry as a cryptoworm. The security community responded with a “kill switch” and patches that largely stopped the infection of computers with WannaCry.
