NHS cyber attack: A&Es 'fully open' again

Over 200,000 infections in at least 150 countries have been recorded

Dr Andrew Cowie, GP at Hawkhill Medical Centre and a member of the NHS Tayside Board, said all the information stored by the practice on Friday had been lost, but staff were still prepared to see patients who had an appointment.

The NHS has been declared "open for business" but some hospitals are still suffering disruption caused by the crippling ransomware attack. It's not uncommon for them to use aliases, either to protect themselves from retaliatory attacks or for privacy.

"Over the last 18 months, we have reduced the proportion of devices in the NHS that use the most vulnerable platform - XP - from 20% to less than 5%", he said, but he admitted "lessons would be learned".

Health secretary Jeremy Hunt has confirmed there has not been a second wave of cyber attacks on NHS trusts since the attacks on Friday.

"The very nature of this particular malware, this sort of ransomware attack, is very potent because unlike more routine ones this one has used a sort of worm to exploit the operating system and bolted on a ransomware so that it spread incredibly quickly in hours not weeks or days", Wallace said.

She said the attack had not been focused on the NHS but was part of a wide worldwide issue, and said the government had invested 2 billion pounds in cyber security.

NHS Digital said health trusts across England were sent details of an IT security patch that would have protected them from the attack.

Over the weekend, a cyber attack the likes of which the world has never seen held important data, pictures, and information hostage demanding Bitcoin ransom payments from anxious users everywhere.

NHS Lanarkshire was among the worst affected in Scotland and was advising only the sickest patients to attend accident and emergency departments.

Several former government officials also weighed in on the attack, highlighting the importance of updating and securing health IT systems.

A United Kingdom -based security researcher who goes by the name MalwareTech put a stop to the spread of WannaCry on Friday by registering a domain name he discovered in the ransomware's code.

On Monday, the opposition Labour Party said Prime Minister Theresa May's response to the crisis had been poor and her government was to blame for failing to invest to keep the service secure. However, officials said the spread was starting to slow.

U.S. software firm Symantec said the majority of organisations affected were in Europe, and the attack was believed to be indiscriminate.

Patch your computers. They should have the latest software update.

Microsoft, which on Friday took the unusual step of issuing a custom security update for users whose systems no longer receive regular support, has urged users with older versions of Windows to patch the vulnerability as soon as possible. Additionally, experts warn that copycats could also try another attack.
