The NHS said 45 of its organisations were hit, with hospitals having to urge people with non-emergency conditions to stay away after the cyber-attack, which demanded a United States dollars 300 ransom in bitcoins for the decryption of files.
SHANGHAI-"Hundreds of thousands" of Chinese computers at almost 30,000 institutions including government agencies have been hit by the global ransomware attack, a leading Chinese security-software provider has said, though the Asian impact has otherwise been relatively muted.
The attackers are only targeting Microsoft Windows, especially the older versions of it.
It's possible that some PCs are already infected - and infections could spread from networks and machines that are already affected, a cyber security expert warned.

NY [U.S.], May 14 (ANI): The World's biggest cyber attack which has hit 200,000 victims in at least 150 countries threatens to create more havoc on Monday when people return to work. More than 200,000 computers have been affected so far.
Oxford University Hospitals NHS Foundation Trust said it has not been affected by the attack but Oxford University Hospitals NHS Foundation Trust communications manager Roy Probert said the trust is still remaining vigilant.
The government on Sunday said it has activated a "preparedness and response mechanism" to prevent any major cyber attack from a new ransomware - "Wannacry" - which has infected computer systems around the world.
"We have seen vulnerabilities stored by the Central Intelligence Agency show up on WikiLeaks, and now this vulnerability stolen from the NSA has affected customers around the world", he wrote. Microsoft released a security update in March to protect against WannaCrypt but Windows XP was excluded from the patch.
"An equivalent scenario with conventional weapons would be the U.S. military having some of its Tomahawk missiles stolen".
