The cyber-attack that crippled the London NHS computer systems on Friday has continued to spread today, Monday as report have that thousands of computers in China and Japan were infected.
One in five NHS Trusts was hit by the “Wannacry” attack on Friday. Operations planned for Monday have been cancelled at several major hospitals.
Earlier, Authorities feared a second wave of the “WannaCry” ransomware could hit systems as people return to work and switch on their computers on Monday morning.
Report coming in from Japanese computer experts said around 2,000 PCs had been affected while the Chinese news agency Xinhua reported that almost 30,000 had been hit.
The attack which has hit companies and other organisations, from Russia to Australia, by Europol estimates there have been 200,000 victims in at least 150 countries.
The WannaCry ransomware, which locks computer systems and demands $300 (£230) in Bitcoin, hit over 200,000 computers on Friday and the impact continued to be felt across the weekend. Around £33,000 in ransoms have been paid to date, according to analysis of Bitcoin wallets.
Microsoft had on Sunday accused the US spy agency that had originally developed software that allowed the ransomware attack to infect computers. The “Eternal Blue” tool developed by the National Security Agency had been dumped onto the public internet by a hacking group known as the Shadow Brokers.
It was then used by the still-anonymous cyber criminals to infect PCs with Friday’s and ongoing ransomware.
