A patient has died after delays caused by a major cyberattack on NHS services, King's College Hospital NHS Foundation Trust has confirmed. The attack, targeting pathology services, resulted in a long wait for blood test results that contributed to the patient's death.

The June 2024 ransomware attack on Synnovis, a provider of blood test services, also delayed 1,100 cancer treatments and postponed more than 1,000 operations. The Russian group Qilin is believed to have been behind the attack that impacted multiple hospital trusts across London.

Healthcare providers struggled to deliver essential services, resorting to using universal O-type blood, which triggered a national shortage. Sensitive data stolen during the attack was later published online, adding to the crisis.

Cybersecurity experts warned that the NHS remains vulnerable because of its dependence on a vast network of suppliers. The incident highlights the human cost of cyber attacks, with calls for stronger protections across critical healthcare systems in the UK.
