We are continuing to work around the clock to support NHS organisations that have reported any issue due to yesterday's cyber-attack.
We have received no reports of patient data being compromised.
We are not publishing a list of those we are assisting at this stage; given the situation is changing and impacting organisations in a range of different ways. For instance we are aware some bodies, which range from practices to trusts, may have suspended selected systems purely as a precautionary measure.
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 per cent, 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.
Our focus remains on assisting organisations, working closely with the National Cyber Security Centre, the Department of Health, NHS England and NHS Improvement.
