NHS cyber attack: Experts fear second wave of ransom ware attacks in hospitals and surgeries

There are concerns the chaos caused by the software will continue as doctors and nurses on the frontline continue to try to deal with the cyber crisis – with further attacks ‘imminent’

There are genuine concerns that the NHS is not through the worse of the cyber attack that crippled 48 of the 248 Trusts across the UK on Friday – and further attacks are ‘imminent’.

UK Home Secretary Amber Rudd said after chairing a meeting of Cobra, the government’s emergency committee, that all but six were now back to normal – after its spread was halted.

But it’s emerged overnight that the invasive ransomware software – which is demanding affected users pay $300 to access their data – might have ‘mutated’ and a new strain of the bug will need dealing with today.

There are also concerns that the true impact of the attack might not be realised until NHS workers returning to work after the weekend attempt to turn on their computers on Monday morning.

Patients with hospital or GP surgery appointments are being urged to turn up on time.

There is no evidence that patient data has been compromised, PM Theresa May has assured the UK.

Meanwhile elusive Health Secretary Jeremy Hunt has still not emerged in public – as the crisis enters its fourth day.
