"As Trump and Kim Met, North Korean Hackers Hit Over 100 Targets in U.S. and Ally Nations... North Korean hackers who have targeted American and European businesses for 18 months kept up their attacks last week even as President Trump was meeting with North Korea’s leader in Hanoi...

With the help of an unnamed foreign law enforcement agency, the McAfee researchers gained access to one of the main computer servers used by the North Korean hackers to stage their attacks. The McAfee researchers said they watched, in real time, as the North Koreans attacked the computer networks of more than a hundred companies in the United States and around the globe.

They were well-researched and highly focused and, in many cases, aimed at engineers and executives who had broad access to their companies’ computer networks and intellectual property...
