UK Working to Restore Hospital Systems After Cyberattack

The head of Turkey’s Information and Communication Technologies Authority or BTK says the nation was among those affected by the ransomware attack.

“We need to get to the bottom of why the Government thought cyber attacks were not a risk, when a combination of warnings and plain common sense should have told ministers that there is a growing and risky threat to our cyber security”, he said. But U.K. hospitals, Chinese universities and global firms like Fedex also reported they had come under assault.

The ransomware appears to have first appeared at 3:24 a.m. ET on Friday, said Craig Williams, a senior technical leader at security company Cisco Talos. The ransomware was created to repeatedly contact an unregistered domain in its code.

The UK could suffer another major cyber attack tomorrow, according to the security researcher who discovered a “kill switch” for the previous one.

“Thus by registering it we inadvertently stopped any subsequent infections”, he told CNNTech.

The NHS systems are believed to have been hit by a ransomware cyber attack using malware called “Wanna Decryptor”.

Europol said Saturday that the attack was of an “unprecedented level and requires worldwide investigation”.

First Minister Nicola Sturgeon, Deputy First Minister John Swinney and Health Secretary Shona Robison were briefed by officials from the National Cyber Security Centre at a Scottish Government resilience (SGORR) meeting. One of the theories is that the attack is primarily an attempt to embarrass the U.S. NSA and the intelligence community. It combined a known and highly unsafe security hole in Microsoft Windows, tardy users who didn’t apply Microsoft’s March software fix, and a software design that allowed the malware to spread quickly once inside university, business and government networks.

A spokesman said the board closed down “non-essential, networked IT systems on a temporary basis”.

Labour’s shadow health secretary, Jonathan Ashworth, in a letter to Mr Hunt, said concerns were repeatedly flagged about outdated computer systems. Two security firms – Kaspersky Lab and Avast – said they identified the malicious software in more than 70 countries. “Most folks that have paid up appear to have paid the initial $300 in the first few hours”.

That said, the threat hasn’t disappeared, the MalwareTech researcher said. WannaCry exploited a vulnerability to spread itself across networks, a rare and powerful feature that caused infections to surge on Friday.

London’s Barts Health NHS Trust, the largest trust in the United Kingdom, canceled all outpatient appointments at its five hospitals Saturday. Security researchers said they observed some victims paying via the digital currency bitcoin, though they did not know what percent had given in to the extortionists.

“It’s an global attack and a number of countries and organizations have been affected”, she said.

Two security firms – Kaspersky Lab and Avast – said they had identified the malicious software behind the attack in upward of 70 countries, although both said the attack has hit Russian Federation hardest.

Nurse Director at NHS Western Isles, Chrisanne Campbell, said: “It’s a global problem and I don’t think we’ve ever seen anything like this before”.

Two big telecom companies, Telefónica of Spain and Megafon of Russian Federation, were also hit.

Although only 22, he is known in the close-knit world of cybersecurity as someone who’s good at “taking down big ugly things that are spreading fast”, in the words of Ryan Kalember, vice president for cybersecurity at Proofpoint, a Sunnyvale, Calif. -based security company.

The attack infected computers with what is known as “ransomware” – software that locks up the user’s data and flashes a message demanding payment to release it.

The U.S. Department of Homeland Security, in a statement late Friday, encouraged people to update their operating systems. That includes the United States, although its effects there didn’t appear to be widespread, at least initially.

“This attack is going to be a wake-up call for many businesses that have dragged their feet when it comes to security and updating their systems”, Bazley said.

Rudd said: “Of the 48 that have been impacted, majority are back to normal course of business, so only six of them have some limits on their business”. Here’s how to turn automatic updates on.

The security holes it exploits were disclosed several weeks ago by TheShadowBrokers, a mysterious group that has published what it says are hacking tools used by the NSA as part of its intelligence-gathering.
