Trump administration blames N. Korea for big ransomware attack

WASHINGTON – President Donald Trump's administration is publicly blaming North Korea for a ransomware attack that infected hundreds of thousands of computers worldwide in May and crippled parts of Britain's National Health Service.

Homeland security adviser Tom Bossert wrote in a Wall Street Journal op-ed published Monday night that North Korea was "directly responsible" for the WannaCry ransomware attack and that Pyongyang will be held accountable for it.

Bossert said the administration's finding of responsibility is based on evidence and confirmed by other governments and private companies, including the United Kingdom and Microsoft.

"North Korea has acted especially badly, largely unchecked, for more than a decade, and its malicious behavior is growing more egregious. WannaCry was indiscriminately reckless," he wrote.
