The government has said the WannaCry ransomware attack in May could have been prevented if basic cyber-security recommendations had been followed.
Over a third of trusts in England were hit by the cyber-attack, which affected more than 150 countries on the 12th May. 6912 appointments, including operations, were cancelled because of the ransomware.
The National Audit Office (NAO), who conducted the investigation, said that there were much more serious cyber-attacks out there, and the NHS had to “get their act together”.
The NAO’s report said NHS trust had failed to act on warnings back in 2014 from the Department of Health and the Cabinet Office to move away from their outdated software, leaving themselves vulnerable.
NHS digital had also advised trusts to install a patch the month before the attack, a measure that has been called ‘basic IT security’.
