WannaCry attack claim baseless, show us proof: North Korea's UN envoy to US

A North Korean ambassador to the United Nations says the US claim that Pyongyang was behind the WannaCry ransomware attack earlier this year is a baseless provocation and demanded Washington back up its accusations with evidence.

The North's UN ambassador in charge of US-related issues says North Korea believes Washington is using the allegation to create an "extremely confrontational atmosphere."

Pak Song Il told The Associated Press in a telephone interview from New York late on Monday: "If they are so sure, show us the evidence."

The WannaCry ransomware attack infected hundreds of thousands of computers worldwide and crippled parts of Britain's National Health Service in May.
