LONDON, June 5, (AP): A Russian cyber gang is believed to be behind a ransomware attack that disrupted London hospitals and led to operations and appointments being canceled, the former head of British cybersecurity said Wednesday.
A group known as Qilin is most likely behind the attack on Synnovis, which provides pathology lab services for several hospitals run by the National Health Service, said Ciaran Martin, former chief executive of the National Cyber Security Centre.
Martin said it was one of the more serious ransomware attacks in the UK because it disabled operations.
“It’s the more serious type of ransomware where the system just doesn’t work,” Martin told BBC Radio 4. “If you’re working in healthcare in this trust, you’re just not getting those results so it’s actually seriously disruptive.”
The incident Monday affected King’s College and Guy’s and St Thomas’ hospital trusts, which run several south London hospitals, as well as clinics and doctors’ practices across a swath of the city, the NHS said.
A memo to staff called it a “critical incident” and said it had a “major impact” on services, particularly blood transfusions. Procedures and operations were canceled or redirected elsewhere.
The incident was reported to police.
Synnovis Chief Executive Mark Dollar said Tuesday that it was still trying to understand what happened. The company offered no further comment Wednesday.
