NHS Cyberattack’s Lasting Impact on Patient Health

In June 2024, the UK’s National Health Service (NHS) faced a severe cyberattack that disrupted healthcare services across London. The target was Synnovis, a pathology provider integral to NHS operations, which suffered a ransomware attack that crippled its IT systems. This breach led to the postponement of over 10,000 outpatient appointments and the cancellation of more than 1,700 elective procedures at major hospitals, including King’s College Hospital and Guy’s and St Thomas’ NHS Foundation Trusts.
