Cyber attacks on London’s hospitals affect 800 planned operations

London hospitals have had to reschedule more than 800 operations and 700 outpatient appointments in the week after a cyber attack, it has been revealed. The disruption was caused by hackers who targeted pathology services provider Synnovis. The National Health Service said the disruption would be felt “for some time,” and warned there is always a risk that in ransomware attacks, people’s data can be accessed.
