Patients of the state-funded country-wide service are facing days of chaos as appointments and surgeries were cancelled after almost 45 NHS organisations from London to Scotland were hit in the "ransomware" attack on Friday. Two security firms " Kaspersky Lab and Avast " said they had identified the malware behind the attack in upward of 70 countries, although both said the attack has hit Russian Federation hardest.
Ransomware is a type of infected software created to take over a computer system and then block access for the authorized user.
"No procedures have been cancelled relating to the cyber attack and patients should attend as planned for their appointments and procedures".
At least 16 organizations connected to the National Health Service in England and an unknown number in Scotland reported being affected. Doctors' practices and pharmacies reported similar problems. However, a hacker could rewrite the code to omit the kill switch and start trying to infect new machines with a new version of it. Hospitals, with their often outdated IT systems and trove of confidential patient data, are a particularly tempting target.
"At this stage, we do not have any evidence that patient data has been accessed".
That means hackers are demanding money for the return of files.
The U.S. Department of Homeland Security said it was sharing information with domestic and foreign partners and was ready to lend technical support.
The worldwide cyberextortion attack has prompted Microsoft to take the unusual step of making security fixes available for older Windows system.
Nissan: The carmaker said in a statement that "some Nissan entities were recently targeted" but "there has been no major impact on our business".
They said cyber incidents represent a growing threat to their economies and should be tackled as a priority.
Eisen says the internet itself is diseased and these attacks will continue until some serious restructuring is done. It initially said 16 NHS organizations had reported being hit, and more reports came in as the day went on.
He said the same thing could be done to crucial infrastructure, like nuclear power plants, dams or railway systems.
Companies across the world have also been affected by the cyber attack.
A cybersecurity expert says the biggest cyberextortion attack in history is going to be dwarfed by the next big ransomware attack.
Elsewhere in Europe, the attack hit Spain's Telefonica, a global broadband and telecommunications company, and knocked ticketing offline for Norway's IF Odd, a 132-year-old soccer club.
Bart's Health, which runs several London hospitals, said it had activated its major incident plan, cancelling routine appointments and diverting ambulances to neighboring hospitals.
The problem appeared to begin Friday morning, when hospitals in the United Kingdom were crippled by a large-scale cyberattack that forced operations to be canceled and ambulances to be diverted.
NHS Western Isles, NHS Fife and NHS Borders also said they had, to some degree, been disrupted.
Apparently, these attacks might have abused a flaw in the documents flew out from the US NSA (National Security Agency).
The statement added: "Local health and care organisations would like to reassure patients that should they need the NHS in an emergency situation that they should access services as they would normally". It was always going to happen. That was a shock.
