who are the Russian criminals thought to be behind cyberattack on NHS?

A Russian cybercriminal group called Qilin is suspected of the cyber-attack that has disrupted NHS services in several major London hospitals. The group, previously named Agenda, operates a “ransomware as a service” model, providing tools to other hackers in exchange for a share of proceeds. They have been active since 2022, targeting multiple sectors worldwide for financial gain. Such cyber-attacks have led to the cancellation of various procedures and operations within the affected hospitals.
