“WannaCry”- the global cyber-attack in May affected more than 230,000 organizations in 150 countries. The ransomware attack targeted companies and computers using Microsoft Windows OS by encrypting data and demanding high ransom in Bitcoin cryptocurrency. Parts of Britain’s National Health Service (NHS), Spain’s Telefónica, FedEx and Deutsche Bahn were hit severely, even leading to operations being cancelled and denial of treatment to patients.
