Hospitals and medical facilities in multiple large cities in the UK are experiencing a serious IT outage because of a ransomware attack on National Health Service computer services. The same malware is being blamed for an attack today against Telefónica, Spain’s largest telecommunications provider, as well as several other companies there.
According to the BBC, major metropolitan NHS facilities are affected including London, Blackburn, Nottingham, Cumbria and Hertfordshire, with one IT provider reporting no fewer than 11 NHS clients affected. Many hospitals are shutting down surgical and general operations, asking patients to only come in if they have a serious emergency.
Meanwhile, in Spain, an outbreak has affected several companies, according to the Spanish government.
The victims included Telefonica (TEF.MC), the nation’s biggest telecommunications firm, while other Spanish firms such as power company Iberdrola (IBE.MC) and utility Gas Natural (GAS.MC) took preventive measures.
“There has been an alert relating to a massive ransomware attack on various organisations, which is affecting their Windows systems,” Spain’s National Cryptology Centre said in a statement.
The ransomware is a version of the WannaCry virus, which encrypts sensitive user data, the National Cryptology Centre said.
WannaCry, also known as WCry and WannaCrypt0r 2.0, affects unpatched Windows systems using the “EternalBlue” exploit, which became public when the hacker collective known as the “Shadow Brokers” released a large number of the exploits and hacking tools online on April 14. The group had previously gained a degree of infamy in 2016 after penetrating one of the NSA’s cyberwarfare launch systems and releasing a large amount of the agency’s hacking library to the public.
