Ransomware Attack on Pathology Services Vendor Disrupts NHS Care in London

 

A ransomware attack on a pathology services vendor earlier this week continues to disrupt patient care, including transplants, blood testing, and other services, at multiple NHS hospitals and primary care facilities in London. The vendor, Synnovis, is struggling to recover from the attack, which has affected all its IT systems, leading to significant interruptions in pathology services. The Russian-speaking cybercriminal gang Qilin is believed to be behind the attack. Ciaran Martin, former chief executive of the U.K. National Cyber Security Center, described the incident as "one of the more serious" cyberattacks ever seen in England. 

Speaking to the BBC, Martin indicated that the criminal group was "looking for money" by targeting Synnovis, although the British government maintains a policy against paying ransoms. Synnovis is a partnership between two London-based hospital trusts and SYNLAB. The attack has caused widespread disruption. According to Brett Callow, a threat analyst at security firm Emsisoft, the health sector remains a profitable target for cybercriminals. He noted that attacks on providers and their supply chains will persist unless security is bolstered and financial incentives for such attacks are removed. 

In an update posted Thursday, the NHS reported that organizations across London are working together to manage patient care following the ransomware attack on Synnovis. Affected NHS entities include Guy's and St Thomas' NHS Foundation Trust and King's College Hospital NHS Foundation Trust, both of which remain in critical incident mode. Other impacted entities are Oxleas NHS Foundation Trust, South London and Maudsley NHS Foundation Trust, Lewisham and Greenwich NHS Trust, Bromley Healthcare, and primary care services in South East London. 

The NHS stated that pathology services at the impacted sites are available but operating at reduced capacity, prioritizing urgent cases. Urgent and emergency services remain available, and patients are advised to access these services normally by dialing 999 in emergencies or using NHS 111. The Qilin ransomware group, operating on a ransomware-as-a-service model, primarily targets critical infrastructure sectors. According to researchers at cyber threat intelligence firm Group-IB, affiliate attackers retain between 80% and 85% of extortion payments. Synnovis posted a notice on its website Thursday warning clinicians that all southeast London phlebotomy appointments are on hold to ensure laboratory capacity is reserved for urgent requests. 

Several phlebotomy sites specifically managed by Synnovis in Southwark and Lambeth will be closed from June 10 "until further notice." "We are incredibly sorry for the inconvenience and upset caused to anyone affected." Synnovis declined to provide additional details about the incident, including speculation about Qilin's involvement. The NHS did not immediately respond to requests for comment, including clarification about the types of transplants on hold at the affected facilities. The Synnovis attack is not the first vendor-related incident to disrupt NHS patient services. Last July, a cyberattack against Ortivus, a Swedish software and services vendor, disrupted access to digital health records for at least two NHS ambulance services in the U.K., forcing paramedics to use pen and paper. 

Additionally, a summer 2022 attack on software vendor Advanced, which provides digital services for the NHS 111, resulted in an outage lasting several days. As the healthcare sector continues to face such cybersecurity threats, enhancing security measures and removing financial incentives for attackers are crucial steps toward safeguarding patient care and data integrity.
