A recent ransomware cyberattack on Synnovis, an organization managing blood transfusions, significantly disrupted services at major London hospitals, causing postponement of operations and blood transfusions. The attack also affected primary care offices in southeast London. The incident underscores cybersecurity risks for the N.H.S., which faced a similar attack in 2017. Despite the government's efforts to improve cybersecurity, recovery from such attacks can take weeks or months, as evidenced by the British Library's plight following a cyberattack in October.
