China and Japan has both announced they have fallen victim to the global "ransomeware" attack, which has caused complete chaos in 150 countries.
Cyber security experts in the National Health Service (NHS) worked alongside the National Cyber Security Centre (NCSC), part of the GCHQ spy agency, to patch computer systems after the attack caused widespread problems on Friday, Mr Wallace said.
Meanwhile, many commentators have criticised Microsoft, for its policy of ending support of older operating systems - a tactic created to encourage large organisations to pay for upgrades to new versions. Russia's Interior Ministry and companies including Spain's Telefonica, FedEx Corp.in the USA and French carmaker Renault all reported troubles. It locks down all the files on an infected computer.
The Ministry of Electronics and Information Technology (MeitY) had said yesterday that a few systems of the Police Department in Andhra Pradesh were impacted and that the state government has been informed to follow the advisory by the CERT-In.
Wainwright said he was concerned that the numbers of those affected would continue to rise when people returned to work on Monday morning.
Security experts globally have shared their thoughts on the devastating cyber attack, and what can and must be done to maintain cyber safety.
They advised those whose networks have been effectively shut down by the ransomware attack not to make the payment demanded - the equivalent of $300, paid in the digital currency bitcoin.
"I went back to theatre [and] was sending for a patient but got word that senior management had chose to suspend all elective surgery. the system we use to order tests, see results, track patient location, document theatre records and writer notes in was down".
The malware behind WannaCry (also called Wana Decryptor or WCry) was reported to have been stolen from the NSA back in April.
Brad Smith, Microsoft president and chief legal officer, described what happened as a "powerful reminder" of the importance of updating software.
And he defended the Government after a National Audit Office report in November warned that taking money away from NHS services would leave them vulnerable. "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", Smith wrote.
"Malware that penetrates the perimeter and then spreads inside the network tends to be quite successful", said Johannes Ullrich, director of the Internet Storm Center at the SANS Institute.
The attack therefore spread faster than previous, smaller-scale ransomware attacks.
"It is important to note that patient care is unaffected and due to the hard work of our staff we have continued to provide normal services".
A 22-year-old UK-based security researchers "Malware Tech" accidentally stopped the Ransomware attack with the help of Darien Huss, a security analyst from the security firm Proofpoint by buying a domain that would act as "kill switch" for the WannaCry virus for $10.69.
"Since the global coordinated ransomware attack on thousands of private and public sector organisations across dozens of countries on Friday, there have been no sustained new attacks of that kind", the NCSC said in a statement.
French carmaker Renault was forced to stop production at sites in France, Slovenia and Romania, while FedEx said it was "implementing remediation steps as quickly as possible".
