In healthcare, every diagnosis, treatment decision, and transfusion depends on one essential element: timely and reliable laboratory results. But what happens when cybercriminals disrupt the systems behind those results?
In June 2024, one of Europe's most significant laboratory-focused cyberattacks provided a stark answer. A ransomware attack on Synnovis, a major pathology provider supporting NHS Trusts across southeast London, demonstrated how a cyber incident can rapidly become a patient care crisis. The attack severely impacted laboratory operations, disrupted blood services, delayed clinical procedures, and highlighted the critical role cybersecurity plays in ensuring continuity of care.
The Incident
On 3 June 2024, Synnovis was hit by a ransomware attack that significantly reduced its capacity to process laboratory tests. Synnovis provides pathology services, including blood testing and specimen analysis, to several NHS organizations and healthcare facilities. The disruption affected healthcare providers across southeast London and had consequences that lasted for months.
The attack caused:
- Severe disruption to laboratory testing services
- Reduced blood testing capacity
- Delays in transfusions and clinical procedures
- Postponement of thousands of appointments and elective procedures
- Extended pressure on healthcare professionals forced to rely on manual workarounds
The financial impact was substantial. Synnovis was required to rebuild significant portions of its IT infrastructure and strengthen security measures while simultaneously restoring essential healthcare services.
Why This Matters
Unlike many cyberattacks that primarily affect administrative functions, the Synnovis incident directly impacted laboratory operations, illustrating how cybersecurity incidents can interfere with the diagnostic processes that support patient care.
- Pathology services are deeply connected to clinical workflows:
- Physicians rely on laboratory data for diagnosis and treatment decisions.
- Blood services depend on rapid and accurate laboratory processes.
- Surgical procedures often require laboratory support and blood product availability.
- Cancer and chronic disease management depend on timely test results.
When laboratory systems become unavailable, the consequences extend far beyond IT. They affect patients, clinicians, and the entire healthcare ecosystem.
Key Lessons for Healthcare Organizations
The Synnovis attack reinforces several important cybersecurity principles:
Cybersecurity Is Patient Safety
Laboratory information systems and diagnostic workflows are mission-critical assets. Protecting them is not only an IT responsibility but a patient safety imperative.
Prepare for Operational Continuity
Healthcare organizations should regularly test business continuity and disaster recovery procedures to ensure clinical services can continue during major disruptions.
Protect Critical Data
Strong access controls, regular backups, network segmentation, and continuous monitoring remain essential safeguards against ransomware attacks.
Build Cyber Resilience
The goal is not only preventing attacks but ensuring rapid detection, response, and recovery when incidents occur.
What Can You Do?
Whether you work in healthcare, laboratories, or within the diagnostics industry, you can help strengthen cyber resilience by:
✅ Following approved cybersecurity policies and procedures
✅ Using strong passwords and multifactor authentication wherever possible
✅ Reporting suspicious emails and unexpected system behavior immediately
✅ Keeping systems and applications updated
✅ Understanding your organization's business continuity plans
✅ Recognizing that cybersecurity and patient safety are closely connected
Cybersecurity is not only about keeping systems online. It's about keeping healthcare moving. [england.nhs.uk], [digitalhealth.net]
