The non-profit U.S. Cyber Consequences Unit research institute estimated that total losses would range in the hundreds of millions of dollars, but not exceed $1 billion.
The WannaCry ransomware attack that wreaked havoc on computer systems around the world over the past few days may be the handiwork of North Korea, some early clues suggest.
A researcher from South Korea's Hauri Labs said on Tuesday their own findings matched those of Symantec and Kaspersky Lab, who said on Monday that some code in an earlier version of the WannaCry software had also appeared in programmes used by the Lazarus Group, identified by some researchers as a North Korea-run hacking operation. The so-called WannaCry ransomware has lines of code that are identical to the malware used by a group of hackers called Lazarus that have been connected to North Korea in the past. Haley previously indicated that new sanctions could target oil, a critical import for North Korea mainly from China, and she said Tuesday the us also wants sanctions on organizations and businesses in third countries that are helping Pyongyang.
The news agency says WannaCry also infected computers at an office of the Taiwan Power Company, a hospital and a business in the central city of Taichung.
Cyber security researchers around the world have said they found evidence that could link North Korea with WannaCry.
After days of disruptions affecting networks worldwide, a top U.S. official said the number of computers affected had reached 300,000, but that infection rates had slowed.
This method, which allows quick and massive infections of computers with security weaknesses, has been found in previously known North Korean cyberattacks, including the Sony hack in 2014 blamed on North Korea.
Barlow said that single payments in some other ransomware cases were more than that, depending on the victim. The Lazarus hackers have been linked to North Korea, raising suspicions that the nation could be responsible for the attack.
FireEye Inc, another large cyber security firm, said it was also investigating a possible link.
Security researchers say China's fondness for pirated software left it especially vulnerable to the latest global cyberattack.
"We all have to send a sign to North Korea, and that is "No more".
"We need to return to dialogue with the Democratic People's Republic of Korea, stop intimidating it and find ways to solve these problems peacefully", Putin was quoted as saying, using North Korea's official name.
But that technique is no sure bet.
The biggest cyber-attacks, hacks and data breaches Sat, May 13, 2017 From viruses to data breaches, cyber-crime is far from a modern invention - here is Express.co.uk's list of some of the biggest attacks in history.
"This can be an attempt to cover traces conducted by orchestrators of the WannaCry campaign". That, in turn, might further narrow the focus on possible suspects. Russian Federation was among the hardest hit, and Britain among the most high-profile, and both have some pretty good investigative capabilities, Cattanach said.
