North Korean cyber attacks not stopped during top Trump and Kim
More than a hundred attacks have been carried out on companies in the United States and other countries during the summit in the Vietnamese capital Hanoi, researchers from the internet security firm McAfee told The New York Times.
The attacks by the North Korean hackers group, also known as Lazarus, on the United States allegedly began in September 2017.
At the time, the tensions between the two countries increased, partly due to nuclear testing and missile testing by North Korea and provocative statements by Trump.
McAfee was granted access to a server that was used by North Korea for attacks by unnamed foreign authorities. According to the researchers, Lazarus has greatly improved his attacks in recent years, including by erasing digital tracks.
The meeting between Trump and Kim ended abruptly and without agreement on Thursday.
It was the first time since June that the two leaders saw each other. At that meeting, which took place in Singapore, they promised to work towards the denuclearization of the Korean Peninsula.
