U.S. declares North Korea carried out massive WannaCry cyberattack

The U.S. government is publicly acknowledging that North Korea was behind the WannaCry computer worm that affected more than 230,000 computers in over 150 countries earlier this year.

As a result, the Trump administration will be calling on “all responsible states” to counter North Korea’s ability to conduct cyberattacks and to implement all “relevant” United Nations Security Council sanctions, according to a U.S. official familiar with the matter.

Trump’s homeland security adviser, Tom Bossert, made the announcement in a Wall Street Journal op-ed Monday evening and will follow up with a statement Tuesday morning.

North Korea was widely suspected to have created the virus, which was paired with ransomware that encrypted data on victims’ computers and demanded money to restore access. Until now, the U.S. government has not publicly stated as much.

In June, The Washington Post reported that the National Security Agency had linked North Korea to the creation of the worm. In October, the British government declared that it believed North Korea was the culprit. The following month, the CIA issued a similar classified assessment, which has not been previously reported.

The official noted that the U.S. government has released technical details of North Korean cyber-tools and operational infrastructure and has worked with other countries to lessen North Korea’s ability to conduct further tests or generate illicit funding.

The May 12 global cyberattack affected critical sectors, including health care, “potentially putting lives at risk,” said the official, who spoke on the condition of anonymity to discuss a move not yet public. This follows a pattern of disruptive and harmful cyber activity by the reclusive country. Its leader, Kim Jong Un, has pushed for the development of hacker forces as a low-cost, high-impact tool that can rattle the nerves and damage the systems of more powerful nations.
