South Korea blames northern neighbor for cyberattack on defense contractor

South Korea claimed North Korea was behind a cyberattack on a navy defense contractor, according to The Register.

The contractor, Hanjin Heavy Industries, produces Seoul's naval vessels and amphibious assault vehicles.

After detecting the hack on April 20, the nation's Defense Security Command began an investigation to determine if any "military secrets were leaked and whether North Korea was involved," unnamed officials told local broadcaster Yonhap.

It is suspected that North Korea hosts sophisticated hacking teams. One group, dubbed Bureau 121, a segment of the General Bureau of Reconnaissance within the nation's military, has been blamed for several cyber attacks, including the hack in 2014 of Sony Pictures after Pyongyang expressed displeasure at the impending release of the studio's film, The Interview, parodying its leader, Kim Jong-un.

North Korea said this latest claim was politically motivated and that the attacks were fabricated.
