There are no known methods to recover files encrypted by WannaCry without giving in to the ransom. Then came word that networks around the world were under attack Friday.

Russia's Interior Ministry acknowledged a ransomware attack on its computers. It was reportedly distributed by the Shadow Brokers, which claimed to have hacked an NSA-linked team of hackers last August.

In fact, Microsoft has never issued security updates for software as long retired from support as Windows XP, which fell off the list more than three years ago.

The threat from the cyber attack that crippled worldwide services "will continue to grow" as people return to work on Monday, the head of Europol warned.

"We're not able to tell you who's behind the attack".

He added: "That's why we're seeing these numbers increasing all the time".

Images appeared on victims' screens demanding payment of US$300 (RM1,301.58) in Bitcoin, saying: "Ooops, your files have been encrypted!"

Not that you should need to.

The exploit can penetrate into machines that are now running unpatched version of Windows through 2008 R2 by exploiting flaws in Microsoft Windows SMB Server.

Hunt goes on to explain that the malware uses the Server Message Block protocol (SMB) to spread and that by disabling this service, you can mitigate WannaCry's ability to go anyway.

United Kingdom politicians are harnessing the attacks to criticize the U.K.'s Conservative Party of Prime Minister Theresa May, which made cuts to the NHS system, Willem Marx reports for NPR's Newscast unit.

Given the ramp up in severity of this situation, we strongly recommend users update their antivirus and anti-malware software to the latest definitions, and obtain the relevant fixes from Microsoft as quickly as possible, in order to prevent an infection on their own machine.

The leaked hacking tools publicized a vulnerability in Windows, Microsoft's ubiquitous computer operating system. Director Dennis So said the systems were not connected to the malls' or tenants' networks.

Dozens of countries were hit with a huge cyberextortion attack Friday that locked up computers and held users' files for ransom at a multitude of hospitals, companies and government agencies.

Japanese broadcaster NTV reported 600 companies in that country had been hit, and automaker Nissan and the Hitachi conglomerate said they were addressing the problem at their units that were affected. The agency did not identify those countries.

Governments and private security firms said on Saturday that they expected hackers to tweak the malicious code used in Friday's attack, restoring the ability to self-replicate.

Economic experts offered differing views on how much the attack, and associated computer outages, would cost businesses and governments.

Security wonks are calling it the biggest cyberattack ever. Cybersecurity isn't a hypothetical problem - today shows it can be life or death.

United Kingdom hospitals were among the organizations affected by the ransomware outbreak.

"The NHS was not particularly targeted". ATM operators, however, say that there is no threat to customer data or money.

"It was actually partly accidental", he told the BBC, after spending the night investigating.

"(The virus) feels random in terms of where it's gone to and where it's been opened", she said.

The U.K.'s National Cyber Security Center says it's working with both the digital office of the NHS and law enforcement.

"There is a danger that if budgets are looked at in silos, it can appear cheaper to leave vulnerable technologies in place without considering the huge cost impact of the operational interruption", he said in a statement in which he noted that numerous affected systems were running unsupported operating systems that were still connected to networks and managing email "with no compensating controls".

In the United States, FedEx was hit.
