F-Secure on Friday says it's gotten reports from more than 60 countries. "Talk about a wake-up call", Hypponen said.
Researchers believe a criminal organization is behind this, given its sophistication.
"I will confess that I was unaware registering the domain would stop the malware until after I registered it, so initially it was accidental", wrote the researcher, who uses the Twitter name @MalwareTechBlog.
"Today our engineers added detection and protection against new malicious software known as Ransom:Win32.WannaCrypt", a spokesperson said in a statement. The ministry said technicians had stopped the attack and were updating the department's "antivirus defence systems", according to the Times. "So they no longer get the security updates they should be".
Friday's attack might prompt companies to reassess the balance.
Friday's attack was based on a Windows vulnerability that was purportedly identified by the U.S. National Security Agency and was later leaked to the internet.
Microsoft has released a patch to fix computers affected by the malware.
Corey Nachreiner, CTO at WatchGuard Technologies, earlier this year predicted we might see a "ransomworm" attack in 2017, that is, an incident in which hackers exploit worm-like flaws to infiltrate systems and spread ransomware.
While most other malware programs trick users into clicking on attachments with the attack code, WannaCry, once inside the systems of affected organization, will seek vulnerable machines and infect them, the BBC said. It's nice of Microsoft to make this security update broadly available, but it's also imperative for Redmond to do so - after all, the reputation of Windows is on the hook. He says "for so many organizations in the same day to be hit, this is unprecedented".
The National Cyber Security Center said it is "aware of a cyberincident".
The spokesman, Jan Op Gen Oorth, declined to give further details Friday so as not to jeopardize the ongoing investigations.
Romania's intelligence service says it has intercepted an attempted cyberattack on a government institution which it said likely came from cybercriminal group APT28 also known as Fancy Bear. Dozens of countries were hit with a huge cyberextortion. The infected computer screens demand payment for the data to be released. The attack was first reported in Sweden, Britain and France.
Authorities said they were communicating with more than 100 energy, transportation, telecommunications and financial services providers about the attack. The vulnerability gave the hackers what amounted to a lock pick to the Microsoft software on computers that did not receive the update from the company or that used outdated operating systems.
The ransomware spread so quickly because it was delivered by a special digital code developed by the NSA to move from one unpatched computer to another, security experts said. "Those who are running our free anti-virus software and have Windows Update enabled, are protected".
Microsoft fixed the problem in a patch it released in March, before a group calling itself the "Shadow Brokers" publicly released it online in April.
In the United Kingdom, 16 organisations in the National Health Service were infected, and hospitals in London, north-west England and central England urged people with non-emergency conditions to stay away as technicians tried to stop the spread of the malicious software.
"This attack was not specifically targeted at the NHS and is affecting organisations from across a range of sectors".
And this is why you may have seen video earlier in the week of McCarthy driving her press podium on the streets of New York City. But if not, this was a fitting send-off for one of the more surprisingly indelible aspects of this season.
But Sanders, who ran for the Democratic presidential nomination previous year , said the U.S. should look to Australia on health. "Again, he was complimenting the prime minister and we're focused on a healthcare plan that works here".
Extremely simplistic in its approach, but driven by fantastic characters and how they interact with one another. I was excited for "Guardians of the Galaxy Vol. 2" and fortunately the film exceeded my expectations.
Most other malicious programs rely on humans to spread by tricking them into clicking on an attachment harbouring the attack code. The company said the virus has been localized and "technical work is underway to destroy it and update the antivirus protection".
Trump "also raised the possibility of broader cooperation on resolving conflicts in the Middle East", the White House said. Lavrov and Trump did not agree to any "specific approaches" to Syria during their meeting on Wednesday, McMaster said.

Jedd Gyorko led off with a home run, and Yadier Molina followed with a single and then stole his 50th career base. Wainwright allowed two runs in five innings in his only start this year, but the Cubs knocked him around in 2016.
Later, Ms Sanders said, "We want this to come to its conclusion, we want it to come to its conclusion with integrity". Trump confirmed that asked Comey on three separate occasions whether or not he was under investigation.
