NHS computer systems are returning to normal after the ransomware cyber attack, health secretary Shona Robison has said.

So it makes sense to assign some responsibility to the NSA - the attackers didn't come up with this security hole on their own, after all.

French carmaker Renault said its Douai plant, one of its biggest sites in France employing 5,500 people, would be shut on Monday as systems were upgraded.

A company official said films were still being screened as scheduled and the company was investigating.

A clamour spread on 12 May 2017 as a malware was launched infecting more than 57,000 computers in almost 100 countries including UK, Russia, Unites states, Spain, china and India.

An official from Cybersecurity Administration China (CAC) told local media on Monday that while the ransomware was still spreading and had affected industry and government computer systems, the spread was slowing.

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.

Microsoft president Brad Smith said this is a wake-up call for governments of the world.

The ransomware attack infected over 75,000 users in over 99 countries, using 28 different languages to demand money from users.

Experts urged organisations and companies to immediately update older Microsoft operating systems, such as Windows XP, with a patch released by Microsoft to limit vulnerability to a more powerful version of the malware - or to future versions that can't be stopped.

"NSA should be embarrassed - they've had a lot of damaging leaks", said James Lewis, a former U.S. official who is now a cyber expert at the Center for Strategic and International Studies.

Whether or not the federal government should withhold knowledge of such vulnerabilities "may seem clear to some", Daniel said at the time, but "the reality is much more complicated".

Information and Technology Minister Ravi Shankar Prasad said the systems run by the National Informatics Centre were secured and running smoothly.

Russian president Vladimir Putin, noting the technology's link to the US spy service, said it should be "discussed immediately on a serious political level".

Accident and emergency units in England were almost back to normal on Tuesday, the National Health Service (NHS) said, after the last restrictions put in place following the global cyber attack were lifted. Hitachi said it believed the difficulties are linked to the global cyberattack but they haven't so far harmed its business operations.

"This was general objective malware and not a targeted virus. It has been a very strong response", she said. "If you're not going to allow the NHS to invest in upgrading its IT, then you are going to leave hospitals wide open to this sort of attack". And if you didn't know that there were 230,000 PC users in the world, well that's on you.

They are now being forced to pay $300 (£230) to continue working on end-of-year projects due to be handed in soon, our correspondent says.
