Following this, US President Donald Trump is, hence, slated to call on "all responsible states" to counter North Korea's ability to conduct cyberattacks and to implement all "relevant" United Nations Security Council sanctions, the Washington Post reported.
He is expected to issue a public statement on Tuesday morning.
Trump's homeland security advisor, Thomas P Bossert, made the announcement in a Wall Street Journal op-ed. He said, "The [WannaCry] attack was widespread and cost billions, and North Korea is directly responsible. We do not make this allegation lightly. It is based on evidence. We are not alone with our findings, either."
The WannaCry cyber attack spread rapidly around the globe using a security flaw in Microsoft's Windows XP operating system, an older version that is no longer given mainstream tech support by the US giant. (ANI)
