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

Cybersecurity expert Ciaran Martin has suggested that Russian cybercriminal group Qilin was responsible for a recent attack on major London hospitals’ pathology services. The action severely disrupted National Health Service (NHS) operations, forcing redirections and cancellations. Known for seeking monetary gain, Qilin operates a “ransomware as a service” model, allowing hackers to use their tools for a share of the money received. The group is known for its attacks on multiple international companies.
