Ambulances diverted to North Mid Hospital following crippling cyber attack

Investigators are working to hunt down those responsible for the Wanna Decryptor ransomware, also known as WannaCry, which encrypts files on a user's computer, blocking them from view and threatening to delete them unless a payment is made.

"And this most recent attack represents a completely unintended but disconcerting link between the two most serious forms of cyber security threats in the world today - nation-state action and organised criminal action".

Following a meeting of the Government's Cobra contingencies committee, Home Secretary Amber Rudd said more than a million patients had been treated in the course of Monday. However, a spokesperson said they are now operating as normal with no disruption to appointments and services.

In a statement on Twitter the trust said: " We are in a period of recovery, having come out of a major incident following the ransomware attack on Friday.

A number of hospitals in England and Scotland were forced to cancel procedures after dozens of NHS systems were brought down in Friday's attack.

The trust says it was infected on PCs that the "patch" did not cover.

Problems with cyber security in NHS organisations were said to have been highlighted past year by Dame Fiona Caldicott, the national data guardian, who warned issues were given insufficient priority and health bodies persisted in using obsolete computer systems.

University of Melbourne computing expert Dr Suelette Dreyfus believes it was possible local organisations had been hit, only they're keeping it under wraps.

Technology powerhouse Microsoft have also responded by re-releasing security updates for older versions of their Windows software in order to mitigate further outbreaks.

However, practices across the North East are still asking patients to consider delaying contacting their practice unless they really need to for the next few days to allow time to clear backlogs caused by the attack.

'There has been a report to the Australian Cyber Security centre of one instance of what we believe could be this ransomware, ' she told reporters in Cairns.

"People going back to work on Monday may switch on their computers and see their systems have been impacted", he said.
