Ms Rudd said the National Crime Agency (NCA) and the National Cyber Security Centre (NCSC) were now part of an “international manhunt” to find the perpetrators. Affected by the onslaught were computer networks at hospitals in Britain, Russia’s interior ministry, the Spanish telecom giant Telefonica and the United States delivery firm FedEx and many other organizations.

The “WannaCry” ransom-ware attack that hit several countries is turning out to be the most risky cyber threat for both corporates and common man, as the global losses are now running into hundreds of millions of dollars.

The tool, known as “WannaCry”, was stolen by a group known as the Shadow Brokers, using a weaponized Microsoft vulnerability developed by the NSA against the warnings of cyber security experts.
