Fewer than 10 US organizations have reported attacks to the Department of Homeland Security since Friday, a USA official told reporters on Tuesday.
But in vain. White House Homeland Security adviser Tom Bossert told reporters, "We are not aware of payments that have led to any data recovery".
The North is internationally suspected of having committed the ransomware attack as it is believed to have associated with Lazarus Group, which is also suspected of hacking into South Korean banks in 2013, Sony Pictures in 2014 and Bangladesh's central bank in February.
As the world struggles to identify the cybercriminals behind the global ransowmware attack that hit 150 countries over the weekend, Neel Mehta, an Indian-origin security researcher working with Google, has claimed on Twitter that the hackers may have links to North Korea. "It is similar to North Korea's backdoor malicious codes", said Choi.
Global cybersecurity firms have pointed at North Korea as the mastermind behind the latest cyberattack.
He cited a major attack past year that stole the data of over 10 million users of Interpark, a Seoul-based online shopping site, in which hackers demanded bitcoin payments worth about United States dollars 3 million.More news: Trump and Turkey's Erdogan hail ties despite US arming of Kurds

North Korea has denied being behind the Sony and banking attacks.
"Since a July 2009 attack by North Korea, they used the same method".
The North Korean mission to the United Nations could not be reached for comment, while the Federal Bureau of Investigation declined to comment. It did not name any of the entities.
"The real situation may be serious".
