Cyber-attack on NHS hospitals

LIVE: Ransoms demanded as cyberattack hits NHS hospitals
The latest developments as NHS hospitals affected by the cyberattack shut down IT systems and divert emergency cases.

At least 16 NHS organisations have been affected by a ransomware attack
NHS Digital says it does not believe that patient data has been accessed
Affected trusts have shut down their IT systems and some are diverting ambulances to neighbouring hospitals


What is Wanna Decryptor?

This is the malicious software that appears to be affecting NHS IT systems.

It encrypts files on computers, blocks them from view and threatens to delete them unless a payment is made.

The virus is usually covertly installed on to computers by being hidden within innocent-looking emails containing links.

Ransoms are typically demanded via Bitcoin, as these transactions are usually harder to trace.

It is possible to remove ransomware such as Wanna Decryptor without payment by using advanced anti-malware software.

The malware can also be removed manually with a computer in "safe mode", however security experts warn this runs the risk of damage to a PC as users must go through sensitive system files in order to find and isolate files created by the Wanna Decryptor software




Personally, I would happily see the death penalty applied to the scumbags that have done this.

http://news.sky.com/story/cyberattack-up-to-74-countries-affected-by-ransomware-say-experts-10874647

Up to 74 countries have been affected by the ransomware cyberattack that has struck the NHS, according to experts.

Among the other nations hit by the attack, dubbed 'Wannacry', are Spain, Russia, Ukraine and India, reported the securelist website.

It said there have been more than 45,000 attacks of the Wannacry ransomware in 74 countries around the world, mostly in Russia.

Securelist added: "It's important to note that our visibility may be limited and incomplete and the range of targets and victims is likely much, much higher."

More follows...

Global Ransomware Attacks 74 Nations - Used NSA Hacking Tools "At A Scale Never Seen Before"

Update 2: Security firm Kaspersky Lab has recorded more than 45,000 attacks in 74 countries in the past 10 hours. Seventy-four countries around the globe have been affected, with the number of victims still growing, according to Kaspersky Lab. According to Avast, over 57,000 attacks have been detected worldwide, the company said, adding that it "quickly escalated into a massive spreading."

Follow
According to Avast, the ransomware has also targeted Russia, Ukraine and Taiwan. The virus is apparently the upgraded version of the ransomware that first appeared in February. Believed to be affecting only Windows operated computers, it changes the affected file extension names to ".WNCRY." It then drops ransom notes to a user in a text file, demanding $300 worth of bitcoins to be paid to unlock the infected files within a certain period of time.

While the victim's wallpaper is being changed, affected users also see a countdown timer to remind them of the limited time they have to pay the ransom. If they fail to pay, their data will be deleted, cybercriminals warn. According to the New York Times, citing security experts, the ransomware exploits a "vulnerability that was discovered and developed by the National Security Agency (NSA)." The hacking tool was leaked by a group calling itself the Shadow Brokers, the report said, adding, that it has been distributing the stolen NSA hacking tools online since last year.

Predictably, Edward Snowden - who has been warning about just such an eventuality - chimed in on Twitter, saying "Whoa: @NSAGov decision to build attack tools targeting US software now threatens the lives of hospital patients."
...etc

http://news.sky.com/story/anatomy-of-a-hack-and-the-anonymous-hero-who-stopped-it-10875234

As hospital after hospital went offline, security researchers around the world started poring over the ransomware that had gone round the globe.

And one 22-year-old in the UK ended up saving thousands more computers across the world being infected.

Working together through the night on an IRC channel - an online chatroom themed around a topic, in this case #wannadecryptor - researchers shared their findings.

Despite the spread of the ransomware, researchers weren't impressed.

"It really doesn't seem like a sophisticated attack at all," one hacker told me. "It's embarrassing the NHS got caught out by this."

:: Live: NHS grapples with cyberattack impact

Other researchers found that the malware was using Tor - anonymity software originally developed by US defence - to communicate with its command and control centre on the deep web (the part of the internet not visible to search engines).

That command and control wasn't active - a sign perhaps "these folks didn't even properly set up their command infrastructure properly before launching", according to another researcher.

And there was another weakness in the malware, found by a 22-year-old security researcher in the UK, who goes by the handle of MalwareTech (MT).

The malware checked a site. MT bought the domain for a few pounds - and ended up slowing the spread of the attack. Without realising it, he had stumbled on a kill switch for the ransomware.

"The kill switch wasn't discovered until about three hours after we'd bought the domain which had already killed all subsequent infections," MT told Sky News.

"From what I can see it killed every infection that contacted our C2 (command and control server)."
...etc

http://news.sky.com/story/nhs-cyberattack-trusts-were-told-about-security-patch-last-month-10878700

NHS England hospital trusts were sent details of a security patch last month that would have prevented Friday's malware attack.

NHS Digital has confirmed to Sky News that the patch was made available on its cyber portal on 25 April, and a link sent to NHS IT staff on 27 April.

A spokesman said: "Our understanding is that if that had been acted on it would have prevented (the malware attack)."

NHS organisations across the country were on alert for a possible recurrence of Friday's cyberattack as staff returned to work on Monday.
..etc.

Which explains why some trusts, like NHS Wales, were unaffected - they actually followed instructions and installed the patch.
