"We will pursue this beautiful vision -- a world of strong, sovereign and independent nations, each with its own cultures and dreams, thriving side by-side in prosperity, freedom, and peace -- throughout the upcoming year."

"The U.S. today publicly attributes the massive 'WannaCry' cyberattack to North Korea," Thomas Bossert wrote in an op-ed published in The Wall Street Journal. "The attack was widespread and cost billions, and North Korea is directly responsible." The ransomware cyberattack targeted companies and governments in at least 150 countries beginning May 12, when the malware virus demanded $300 per computer to restore access after taking control of computer systems. Bossert asserted in The Wall Street Journal that other governments and private companies agree with the United States' findings, stating Britain also attributes the attack to North Korea and Microsoft has traced the attack to cyber affiliates of the North Korean government.
