NHS England hospital trusts were sent details of a security patch last month that would have prevented Friday's malware attack. It exploits a vulnerability in the Windows software and encrypts data on a device before demanding payment $300 in Bitcoins for the data to be unencrypted.
NHS Wales has announced that none of its computer systems have been impacted and no patient data affected by a global cyber-attack. It appears to exploit a vulnerability in Windows that, according to the Toronto Star, "was supposedly identified by the U.S". Ensuring that your Windows operating system is up to date with the most recent security and software updates, which patch any holes and vulnerabilities in the software, makes it much more hard for a hacker to infiltrate your system and networks.
NHS services across the region say they are extremely busy as a result of the cyber attack and are asking the public to only use A&E, Global Positioning System practices and the NHS 111 phone-line, if absolutely necessary. "This is not something that is specific to the NHS [it] has affected leading edge companies including FedEx, Telefonica, Nissan and Deutsche Bahn".
Why hadn't NHS Trusts updated their software?
"They have been working I know through the night nearly to make sure patches are in place to make sure that hopefully the NHS services can get back to normal", he told BBC radio. We are obviously working with that business the Australian Cyber Security Centre is engaging with them'. "We have seen no impact on our critical infrastructure, we have seen no impact in the health systems which is important, we have had no reports of any government agencies, state, territories or commonwealth impacted by this", MacGibbon said. Why were so many NHS systems still running this out-of-date software?
A divert remained in place for trauma, stroke and urgent heart attack treatment, where diagnostic services are required, at the Lister Hospital, part of East and North Hertfordshire NHS Trust (Midlands & East).
The government was aware of the problem as early as 2014, with the Cabinet Office writing to NHS trusts to insist that they should "clearly understand the risk" of being left unprotected.
The Liberal Democrats have joined calls for an inquiry.
'It's an worldwide attack and a number of countries and organisations have been affected, ' British Prime Minister Theresa May said.
There have been calls for the government to invest more in cyber security.
But no new large-scale outbreaks were reported, and British officials said a feared second wave of infections had not materialized. Hospitals, universities, manufacturers and government agencies in Britain, China, Russia, Germany and Spain have all been affected.
"They must also spend the cash to protect staff and patients from future incidents".
Dozens of public and private sector organisations in 150 countries across the world had their computers hit last week in a "ransomware" attack.
The best course of action is to contact an IT or Cyber Security professional to assist you in analyzing and minimizing the attack.
