The aftermath of the "major" cyber attack which has hit the NHS is likely to last for a number of days, experts have said.
A total of 48 NHS trusts in England and 13 NHS health boards in Scotland were crippled in the global attack on Friday when a ransomware virus infiltrated dozens of NHS organisations.
Five NHS England trusts were still not back to normal on Saturday, despite NHS Digital engineers working "around the clock" in a bid to fix the problem.
NHS Digital continued that fewer than five per cent of devices within the health service still use the old Windows XP system.
"We are aware of widespread speculation about the use of Microsoft Windows XP by NHS organisations, who commission IT systems locally depending on population need.
"While the vast majority are running contemporary systems, we can confirm that the number of devices within the NHS that reportedly use XP has fallen to 4.7%, with this figure continuing to decrease.
"This may be because some expensive hardware (such as MRI scanners) cannot be updated immediately, and in such instances organisations will take steps to mitigate any risk, such as by isolating the device from the main network."
Experts have vowed to track down the criminals responsible for the global cyber attack that brought parts of the NHS to a standstill.Read the full story ›
China and Japan have both fallen victim to the global "ransomware" cyber attack that has created chaos in 150 countries.
Chinese state media say more than 29,000 institutions across the country have been infected, along with hundreds of thousands of devices.
Xinhua News Agency cited the Threat Intelligence Centre of Qihoo 360, a Chinese internet security services company.
It said universities and educational institutions were among the hardest hit, numbering 4,341, or about 15% of internet protocol addresses attacked.
Also affected were railway stations, mail delivery, petrol stations, hospitals, office buildings, shopping malls and government services.
The Japan Computer Emergency Response Team Co-ordination Centre said 2,000 computers at 600 companies in Japan had been affected.
Government bodies and other organisations could also be affected by the malware attack that brought down some NHS services, a cyber security expert has warned.
Companies operating large networks, thought to be particularly vulnerable, are being urged to make sure they are secure in the wake of the attack.
"Absolutely it's highly possible that as the days come forward unfortunately we are going to hear that more organisations and government bodies are going to have been affected," cyber security expert Paul Norris said.
"Unfortunately, it's going to be big names and it's going to be organisations that have got weakened security controls that are going to be mostly impacted by this."
The full scale of the global cyber attack that caused mass NHS disruption may only become apparent when people return to work on Monday.Read the full story ›
