WASHINGTON—The White House on Tuesday blamed North Korea’s government for a massive cyberattack in May that crippled hundreds of thousands of computers around the world, weeks after the U.K. had already cast blame on the country.
North Korea launched the virus, known as WannaCry, in a “careless and reckless attack” that damaged businesses and put lives at risk, Tom Bossert, the White House homeland security and counterterrorism adviser, told reporters. Hospital computer systems in the United Kingdom were hit by the attack, and schools and business were also affected.
