Legacy technology could be leaving the NHS open to cyber attacks, according to new research.The discovery was made by staff at Check Point Software, who found exploits in widely used fax machines that could allow hackers to spread malware through a malicious image file. Check Point uncovered that malware could be coded into an image file which, when decoded by the fax machine and uploaded to its memory, would spread through any network it is connected to. Hackers would only need to know the fax number of the organisation it wishes to target, which can be easily found online.It is thought that the NHS still has 9,000 fax machines, despite many organisations ceasing to use them some time ago.NHS Digital said the threat posed by hacked fax machines was minor.
