Yet another attack has been observed in the larger trend of attacks against the healthcare industry. The Qilin ransomware gang is the apparent culprit behind a ransomware attack on Synnovis, a pathology services provider based in London, that occurred earlier this week on June 3, 2024. Qilin is a likely financially motivated Russian cybercriminal group that performs double-extortion attacks with encryptors specially designed to target VMware ESXi virtual machines. Their attack has resulted in Synnovis being locked out of its system as well as additional service disruptions. The ransomware attack had further consequences, also disrupting a handful of major NHS hospitals in London, causing a “critical incident” declaration as medical operations of some of London’s largest hospitals had to be cancelled. Memos that were released by officials at the affected hospitals have stated that this is an ongoing critical incident and an NHS incident response team is actively investigating both the extent and impact of the attack. The Synnovis customer portal is currently inaccessible and has a warning reporting that all systems are down due to datacenter issues. Urgent and emergency services are still operational, such as urgent care centers and maternity departments, but non-emergency pathology appointments have either been postponed, canceled, or redirected to alternate service providers.
