A patient’s unexpected death has been officially linked to the crippling cyber-attack on the NHS in June 2023. The attack, allegedly orchestrated by Russian-linked ransomware group Qilin, disrupted pathology services across major London hospitals, causing treatment delays, mass cancellations, and the largest known data breach in NHS history.
From Malware to Mortality: How a Cyber Attack Turned Deadly
A year after the ransomware attack that shook Britain’s healthcare system, King’s College Hospital NHS Foundation Trust has confirmed what many feared: a patient died as a direct result of care delays caused by the incident. In a statement issued Wednesday, the trust acknowledged that a “long wait for a blood test result”, disrupted by the cyber-attack, was among the contributing factors in the patient’s death.
This tragic consequence casts new light on the real-world toll of cyber warfare in the public sector. While past ransomware incidents have focused on financial or operational damage, this case represents one of the first confirmed fatalities in the UK tied to a digital attack on critical health infrastructure.
Disruption on an Unprecedented Scale: Delays, Cancellations, and System Overload
The June 3, 2023, cyber assault targeted Synnovis, a major pathology services provider in southeast London. The ripple effects were catastrophic. More than:
- 1,000 cancer treatments were delayed
- 2,000 outpatient appointments were cancelled
- 1,000 surgeries were postponed
Affected NHS Trusts included Guy’s and St Thomas’, King’s College, and Lewisham and Greenwich, along with six boroughs of primary care and two mental health trusts.
Synnovis was forced to cancel testing for 20,000 blood samples involving 13,500 patients, as samples “degraded” before they could be processed. In their absence, NHS staff were forced to rely on universal O-type blood for transfusions, triggering a national blood shortage, NHS England later confirmed.

The Shadow War
According to cybersecurity sources, the Russian-linked ransomware group Qilin was responsible for the breach. The group reportedly exfiltrated nearly 400GB of sensitive data, which was later leaked on the dark web and Telegram channels. Among the data compromised were:
- Patient names, birthdates, and NHS numbers
- Descriptions of blood tests
- Financial agreements between NHS providers and GP services
Experts fear the exposed data could lead to secondary fraud, identity theft, or even targeted extortion of vulnerable patients.
The UK’s National Cyber Security Centre (NCSC) and NHS Digital launched an urgent review, but have yet to fully trace how the attackers breached Synnovis systems. Meanwhile, healthcare professionals continue to operate under tighter cybersecurity protocols and heightened alert.
