🎯Basically, a ransomware attack is still causing problems for hospitals in London nearly two years later.
What Happened
In June 2024, a ransomware attack by the Qilin group severely disrupted healthcare services in South East London, particularly affecting the Synnovis laboratory, which handles blood testing. Nearly two years later, internal documents reveal that at least one NHS trust, the South London and Maudsley NHS Foundation Trust (SLaM), is still struggling with unrestored systems and significant backlogs of test results.
The attack forced hospitals to cancel operations and delay treatments, jeopardizing patient care. It also led to a critical shortage of blood supplies, with officials warning that only the most essential transfusions might be prioritized.
Who's Affected
The ongoing effects of this ransomware attack have impacted multiple NHS trusts across South East London. The SLaM trust has been particularly hard hit, relying on manual processes for pathology reports due to the failure of their electronic systems. This has resulted in delays for over 161,560 pathology reports as of early January 2026. Patients with serious conditions, including cancer and sexually transmitted infections, were among those affected, with sensitive data potentially exposed during the attack.
Signs of Infection
While the ransomware attack itself occurred in June 2024, the signs of its long-term impact are evident in the ongoing operational challenges faced by the affected NHS trusts. Delays in test results and patient safety incidents have been reported, with 122 incidents of incorrect or delayed pathology results recorded by SLaM. Clinicians have been advised not to rely on timely blood results, indicating a systemic issue stemming from the attack.
How to Protect Yourself
For healthcare organizations, the lessons from this incident are critical. Here are some steps to enhance resilience against ransomware attacks:
Detection
- 1.Regular Backups: Ensure that all systems are backed up regularly and that backups are stored securely offline.
- 2.Incident Response Plans: Develop and regularly update incident response plans that include contingency measures for when systems fail.
Removal
- 3.Staff Training: Train staff on recognizing phishing attempts and the importance of cybersecurity hygiene to prevent initial breaches.
- 4.System Updates: Regularly update and patch systems to protect against known vulnerabilities that could be exploited by ransomware.
Conclusion
The Synnovis ransomware attack serves as a stark reminder of the vulnerabilities within healthcare systems. As organizations continue to recover, the focus must remain on strengthening defenses against future cyber threats. The NHS must prioritize cybersecurity to safeguard patient data and ensure that healthcare services can operate effectively, even in the face of digital disruptions.
