NHS Lanarkshire has identified the source of malware which affected its systems on Friday and is investigating how it was able to infiltrate its network.
The trust said in a statement: “Following the detection of some incidences of malware on Friday staff within ehealth have worked overnight to secure and reinstate our IT systems.”
Chief executive Calum Campbell added: “We have identified the source of the malware and investigations are ongoing as to how this was able to infiltrate our network.
Lanarkshire contingency plans
“Our staff have worked hard to minimise the impact on patients and our contingency plans have ensured we have been able to continue to deliver services while the IT issues were resolved. A small number of systems have been affected and these are in the process of being fixed,” said Campbell.
“Unfortunately, a small number of procedures and appointments have been cancelled as a result of the incident. I would like to apologise to anyone who has been affected by this disruption, however I can assure you that work is already underway to reappoint patients.
“The majority of services have been restored but it may take some time to get services running as normal. We would ask patients who are attending hospital or out-of-hours services over the weekend to bear with us as they may experience longer than waits than usual.”
Incident follows ‘WannaCry’ attack
Last May, a global cyberattack using hacking tools widely believed by researchers to have been developed by the US National Security Agency crippled the NHS, hit international shipper FedEx and infected computers in 150 countries.
More than 300,000 computers were infected while the countries most affected by WannaCry were Russia, Taiwan, Ukraine and India, according to Czech security firm Avast.
Hospitals and GP surgeries in England and Scotland were among health service organisations hit by the “ransomware” attack. Staff were forced to revert to pen and paper and use their own mobiles after the attack affected key systems, including telephones.
