Europol described it as "unprecedented" and said its cyber-crime team was working with affected countries to "mitigate the threat and assist victims". "We are continuing to monitor the situation".
"The software has actually stopped spreading across the world", he told CNN.
Renault said it had halted auto production at several sites including Sandouville in northwestern France and Renault-owned Dacia plants in Romania on Saturday to prevent the spread of ransomware in its systems. The ransomware was created to repeatedly contact an unregistered domain in its code.
The researcher, tweeting as @MalwareTechBlog, said the discovery was accidental, but that registering a domain name used by the malware stops it from spreading.
"We are on a downward slope, the infections are extremely few, because the malware is not able to connect to the registered domain", said Vikram Thakur, principal research manager at Symantec.
Cyber security experts rushed to restore systems on Saturday after an unprecedented global wave of cyberattacks that struck targets ranging from Russia's banks to British hospitals and a French carmaker's factories.
However, @MalwareTechBlog warned that the "crisis isn't over" as those behind it "can always change the code and try again".
Meanwhile, the MalwareTech tracker detected over 100,000 infected systems over the past 24 hours.
Individuals and organisations are discouraged from paying the ransom, as this does not guarantee access will be restored, the USCERT said.
European police agency Europol said it was working to support countries, saying the malware attack was at an "unprecedented level and requires worldwide investigation".
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.
In a blog post, the US tech giant recalled that it had published an update in March to address the weakness exploited in Friday's attacks, a security flaw exposed in documents leaked from the US National Security Agency. There was much warning about XP no longer receiving updates etc, the 2001 operating system just needs to die however so many programs especially embedded devices rely upon the fact that the OS running is Windows XP, This is a problem that needs sorted sooner rather than later.
It demands users pay United States dollars 300 worth of cryptocurrency Bitcoin to retrieve their files, though it warns that the payment will be raised after a certain amount of time. Fortune reported Thursday that the price of bitcoin was at an all-time high. "Ambulances are being diverted to neighbouring hospitals".
She said there is no evidence that patient records have been compromised. Doctors told him two weeks ago they needed to schedule a prostate biopsy to determine if he has cancer. So far, hospitals in the north, south west of England and the south are said to have been hit following a supposed hack on Friday afternoon. "If I know I have cancer, I could deal with it". Users should download the patch before clicking on any link in email.
The ransomware is a type of malicious software that infects a computer and restricts users' access to it until a ransom is paid to unlock it. Here's how to turn automatic updates on. Computers already affected will not be helped by the solution.
Tens of thousands of ransomware attacks Friday targeted organizations around the world, including 16 that are part of the National Health Service.
"I believe many companies have not yet noticed", said William Saito, a cyber security adviser to Japan's government. "Today we see the cost". Bitcoin is set up to be untraceable, so investigators will struggle to follow a money trail, he said.
"I think these hackers have to recognize that these authorities will come after them with a vengeance", Gazeley said.
It was not yet known who perpetrated Friday's attacks.
