UK working to restore hospital systems after cyberattack

  • 'Biggest ransomware outbreak in history' hits nearly 100 countries

Hospitals in London, north-west England and central England have all been affected, according to the BBC.

"I believe many companies have not yet noticed", said William Saito, a cyber security adviser to Japan's government.

In December, it was reported almost all NHS trusts were using an obsolete version of Windows that Microsoft had stopped providing security updates for in April 2014. And because lives are at stake, he thinks hospitals may be more likely to pay up.

Rudd said the attack was not specifically targeted at Britain's health service.

The Scottish Daily Mail says desperate NHS staff urged patients to stay away from A&E unless it was an emergency.

She did not elaborate on how the six remaining health groups were affected or where they were located.

HOSPITAL bosses were this morning advising patients to attend clinics and appointments as usual as they stressed The Dudley Group NHS Foundation Trust was not among trusts hit by the NHS cyber attack.

Some experts say the attack may have been built to exploit a weakness in Microsoft systems that had been identified by the NSA and given the name EternalBlue.

With the cyber attack, the software of NHS was blocked and doctors were blocked from patient files.

Russia's largest bank Sberbank said its systems "detected in time attempts to penetrate bank infrastructure".

"It's going to happen more and more", he said. The British-based researcher who may have foiled the ransomware's spread told Reuters he had not seen any such tweaks yet, "but they will".

Authorities in Britain have been braced for possible cyberattacks in the run-up to the vote, as happened during last year's United States election and on the eve of this month's presidential vote in France.

The paper quoted the researcher as saying: "This is not over".

Hospitals in areas across Britain found themselves without access to their computers or phone systems.

Who has it affected so far?

However, a new variant dubbed WannaCry was created that makes use of a vulnerability in the Windows operating system that was patched by Microsoft on March 14.

The malicious software appeared to exploit a vulnerability in Microsoft Windows that was supposedly identified by the US National Security Agency for its own intelligence-gathering purposes and was later leaked to the internet.

The ransomware encrypts data on the computer using an encryption key that only the attacker knows.

The researcher, tweeting as @MalwareTechBlog, said registering a domain name used by the malware stops it from spreading, though it can not help computers already affected.

Renault representative Nevenka Basek Zildzovic confirmed that "some troubles occurred with some parts of IT system at Revoz".

The spokesman added that there was no production scheduled to begin today.

The two unionists spoke on condition of anonymity because of the sensitiveness of the issue.

"The networks at the three affected community sites have been isolated, software has been shut down, and there is no immediate risk to patient care or confidentiality", it said.

The consequences for the company remained unclear. It initially said 16 NHS organizations had reported being hit, and more reports came in as the day went on.
