South Korean police have leveled allegations against a suspected North Korean group of hackers, claiming it attempted to disrupt the upcoming huge joint war game between the military forces of Seoul and Washington, due to begin on Monday.
The Gyeonggi Nambu Provincial Police Agency alleged in a statement on Sunday that the hackers were believed to be linked to a North Korean group that researchers call Kimsuky, and they carried out their hack via emails to South Korean contractors working at the South Korea-US combined exercise war simulation center.
It further claimed that a joint investigation by the South Korean police agency and the US military had found that the IP address used in the latest attack targeting the war simulation center of the allies' joint military drills matched the IP identified in a 2014 hack against South Korea’s nuclear reactor operator.
The statement added that military-related information was not stolen.
North Korea has previously denied any role in cyberattacks.
