Organizations around the world were digging out this weekend from what experts are calling one of the biggest cyberattacks ever.

Hospitals, major companies and government offices were hit by a virus that seeks to seize control of computers until the victims pay a ransom.

Experts said that even as the spread of the attacks apparently has been stymied, its full ramifications are not yet known because the virus may be lurking still on computers around the world.

Cybersecurity firm Avast said it had identified more than 75,000 ransomware attacks in 99 countries on Friday, making it one of the broadest and most damaging cyberattacks in history.

Avast said the majority of the attacks targeted Russia, Ukraine and Taiwan. But U.K. hospitals, Chinese universities and global firms like Fedex (FDX) also reported they had come under assault.

Security experts said the spread of the ransomware had been inadvertently stopped late Friday. The ransomware was designed to repeatedly contact an unregistered domain in its code. A 22-year-old security researcher in the U.K, who goes by MalwareTech, registered that domain to analyze the attack, but it turned out the ransomware needed it to remain unregistered to keep spreading.

"Thus by registering it we inadvertently stopped any subsequent infections," he told CNNTech.However, a hacker could change the code to remove the domain and try the ransomware attack again.

It remained unclear how many organizations had already lost control of their data to the malicious software -- and researchers warned that copycat attacks could follow.Europol said Saturday that the attack was of an "unprecedented level and requires international investigation." And the U.K. government called an emergency meeting over the crisis.U.S. Treasury Secretary Steven Mnuchin, at a meeting of world leaders in Italy, said the attack was a reminder of the importance of cybersecurity. "It's a big priority of mine that we protect the financial infrastructure," he said.The ransomware, called WannaCry, locks down all the files on an infected computer and asks the computer's administrator to pay in order to regain control of them. The exploit was leaked last month as part of a trove of NSA spy tools.

The ransomware is spread by taking advantage of a Windows vulnerability that Microsoft (MSFT, Tech30) released a security patch for in March. But computers and networks that hadn't updated their systems were still at risk.In the wake of the attack, Microsoft said it had taken the "highly unusual step" of releasing a patch for computers running older operating systems including Windows XP, Windows 8 and Windows Server 2003.

But the patches won't do any good for machines that have already been hit."Affected machines have six hours to pay up and every few hours the ransom goes up," said Kurt Baumgartner, the principal security researcher at security firm Kaspersky Lab. "Most folks that have paid up appear to have paid the initial $300 in the first few hours."On Saturday, experts said it appeared that the ransomware had made just over $20,000, although they expected that number to pop when people went back into the office Monday.

Sixteen National Health Service organizations in the UK were hit, and some of those hospitals canceled outpatient appointments and told people to avoid emergency departments if possible. The NHS said in a statement on Saturday that there was no evidence that patient information had been compromised.In China, the internet security company Qihoo360 issued a "red alert" saying that a large number of colleges and students in the country had been affected by the ransomware, which is also referred to as WannaCrypt. State media reported that digital payment systems at PetroChina gas stations were offline, forcing customers to pay cash.

"Global internet security has reached a moment of emergency," Qihoo360 warned.Major global companies said they also came under attack.Fedex said Friday it was "experiencing interference with some of our Windows-based systems caused by malware" and was trying to fix the problems as quickly as possible. Two big telecom companies, Telefnica (TEF) of Spain and Megafon of Russia, were also hit.

"This is turning into the biggest cybersecurity incident I've ever seen," U.K.-based security architect Kevin Beaumont said.
