North Korean Hackers Called Active While Trump Met with Kim Jong-un

North Korean hackers who have targeted American and European businesses for 18 months kept up their attacks even as President Trump was meeting with North Korea’s leader in Hanoi. The attacks, which include efforts to hack into banks, utilities and oil and gas companies, began in 2017, according to researchers at the cybersecurity company McAfee, a time when tensions between North Korea and the United States were flaring.
