IMPACT: 170 patients harmed as a result of Qilin’s ransomware attack on NHS vendor Synnovis

Posted on June 18, 2025 by Dissent

PA News Agency reports that as a result of the attack, more than 10,000 appointments were cancelled at the two London NHS trusts that were worst affected, and a significant number of GP practices in London were unable to order blood tests for their patients.

Now the Health Service Journal (HSJ) [paywalled] has reported that there were nearly 600 “incidents” linked to the attack, with patient care suffering in 170 of these.

This includes one case of “severe” harm, 14 which led to “moderate” harm with the rest identified as “low harm”.

In January, news broke that two cases of major harm, 11 cases of moderate harm, and more than 120 cases of minor harm had been reported as a consequence of the Qilin attack on Synnovis. This new report updates those estimates.
