Grantham Hospital 'routine activity' cancelled following cyber attack

16 Mai 2017

One security researcher called Malware Tech has released a killswitch that has slowed the WannaCry rampage, but experts are quick to point out the danger of having your computer remotely hacked is still very real. Its impact will be felt for a long time to come.

Australian officials said so far only three small-to-medium sized businesses had reported being locked out of their systems while New Zealand's ministry of business said a small number of unconfirmed incidents were being investigated.

'Do not pay ransomware ransom - unless there is a threat to life.

The malware attack first emerged on Friday night but there were concerns of more disruption as workers switch on their computers this morning.

WannaCry encrypts files with the following extensions, appending '.WCRY' to the end of the file name like.lay6, .sqlite3, .sqlitedb, .accdb, .java and.docx among others.

A global tracker of the malware built by United Kingdom researcher MalwareTech - who stopped the ransomware from spreading further over the weekend simply by buying a domain - indicates the rate of infection in Australia could be much higher than the confirmed eight reports. The ease of stopping the attack suggests the hackers were new to this game.

The chilling reality is that WannaCry is just one example of what a cyber weapon - believed to have been created by the NSA using American taxpayers' money - could actually do. But it was paired with the "EternalBlue" exploit that was developed by the NSA and leaked online earlier this year by hacking group called Shadow Brokers, and it spread across the globe.

Almost hundred countries, including India, were hit by a massive cyber attack which experts said was carried out with the help of "cyber weapons" stolen from the US' National Security Agency.

They advised those whose networks have been effectively shut down by the ransomware attack not to make the payment demanded - the equivalent of $300, paid in the digital currency bitcoin, delivered to a likely untraceable destination that consists merely of a lengthy string of letters and numbers.

"Particularly careful clicking on links or opening attachments like a photo or a file".

Now that this "WannaCry" malware is out there, the world's computer systems are vulnerable to a degree they haven't been before, unless people everywhere move quickly to install Microsoft's security patches.

Senior US security officials held another meeting in the White House situation room on Saturday, and the Federal Bureau of Investigation and the National Security Agency were working to help mitigate damage and identify the perpetrators of the attack, said the official, who spoke on condition of anonymity to discuss internal deliberations. "Doing so fuels the ransomware economy, funding development of additional ransomware techniques and campaigns".

"Cyber experts have been engaged to fix the systems", a senior police officer said.

Ransomware has a habit of mutating and so it changes over time in order to find different ways to access computers or to get around patches (operating system updates that often include security updates).

Wainwright said Europol had been concerned about cyber security in the healthcare sector, which deals with a lot of sensitive data, but declined to comment on whether Britain's National Health Service had been adequately funded.

Writing on his Twitter account, he said journalists had already tracked down a friend, whose photograph was published in the press and turned up at her house, saying: "Please if you want an interview that badly, DM me".

A divert remains in place for trauma, s troke and urgent heart attack treatment, where diagnostic services are required, at t he Lister Hospital, part of East and North Hertfordshire NHS Trust (Midlands & East).

The spokesman played down suggestions the NHS was placed at additional risk because of its use of Windows XP.

"Each health building will have an IT representative to provide assistance in the morning".

However, the scale of the incident has prompted global co-ordination from governments and law enforcement.
