Malware Cyberattack Hits English Hospitals and FedEx, Hackers Demand Bitcoin

13 Mai 2017

While many ransomware infections require a victim to open an email attachment or click a link, Friday's attack is notable for its worm-like ability to spread - in other words, its ability to copy itself between vulnerable machines without user intervention.

It has been reported that up to 25 NHS organisations and some GP practices have been affected. And, we are not aware of any evidence that patient data has been compromised.

Spafford said ransomware typically targets those without strong security in place, such as home users and small companies.

Kaspersky Lab said its team has confirmed additional infections in additional countries, including Ukraine and India.

Cybersecurity expert Ralph Echemendia called WannaCry, "the biggest Ransomware attack of all time".

"The virus has been localised".

Volk added that some 1,000 computers - less than one percent of their total number - had been affected, Interfax reported.

In the three months after the centre was launched there were 188 "high-level" attacks as well as countless lower-level incidents. "The intelligence community should develop strong procedures that when such tools leak, the immediately give relevant information to software developers and security vendors so protections can be developed before attacks are seen in the wild", said Bambanek.

The malware's name is WCry, but analysts were also using variants such as WannaCry.

In Spain, the attacks did not disrupt the provision of services or networks operations of the victims, the government said in a statement.

The UK's National Health Service (NHS) was also hit by a ransomware outbreak on the same day and screenshots of the WannaCry program were shared by NHS staff.

The first indication of the cyber-attack in the United Kingdom came around 3.30pm yesterday afternoon when organisations within NHS England reported that computers had been hit by a ransomware attack using Wthe anna Decryptor malware.

UO Says State's Rejection Of Tuition Increase Is A "Tremendous Setback"
Even with the tuition increase, the University has a $9 million shortfall and is making cuts to faculty, Haaga said. The HECC votes against raising tuition were welcomed by student groups that rallied this spring against the hikes.

Mrs May said: "We are aware that a number of NHS organisations have reported that they have suffered from a ransomware attack".

Patched computers were protected, but unfortunately many large organisations, such as the NHS, are slow to apply patches to all PCs, and some even run operating systems such as Windows XP which is no longer supported and will therefore never be patched.

First Minister Nicola Sturgeon chaired a resilience meeting on the issue and Police Scotland confirmed they were working closely with the National Cyber Security Centre and the National Crime Agency to support the investigation.

On the affected computer screens, the malware threatens to erase all of the computers' files if a payment of $300 in bitcoin is not made within a week.

"It had a countdown clock ticking down, stating that all data would be deleted unless a payment was received within that timeframe", he said.

Friday's attacks are being blamed on a piece of malware called WCry, WannaCry, or Wana Decryptor, that's now been tracked in large-scale attacks across Europe and Asia - particularly Russian Federation and China - as well as attacks in the USA and South America, according to a map on the Malware Tech site.

Ransomware was also in nearly 40% of spam email in 2016, according to an IBM Security study.

But sometimes, hackers hit the jackpot: Last year, Hollywood Presbyterian Medical Center forked over $17,000 after suffering a ransomware attack.

"Ransomware becomes particularly nasty when it infects institutions like hospitals, where it can put people's lives in danger", said Kroustek, the Avast analyst.

A spokesman for Barts Health NHS Trust in London said it was experiencing "major IT disruption" and delays at all four of its hospitals.

"At this stage we do not have any evidence that patient data has been accessed", the system says. Routine appointments had been canceled and ambulances were being diverted to neighboring hospitals. Management quickly told the around 15,000 employees to turn off their computers until further notice.

An IT worker at the public health care system tells The Guardian newspaper that it's the biggest problem they've seen in their six years working for the service. "They said the system was down and that they can not transfer anyone till the computer system was back up so he is still in the theatre".
