    Suspected North Korean hackers last year stole a vast cache of data from Daewoo Shipbuilding and Marine Engineering, which is manufacturing a new 3,000-ton submarine for the Navy.

    They also recently attacked the state-run Korea Atomic Energy Research Institute, which was involved in the development of a small reactor to power nuclear submarines.

    North Korea probably wanted the information to develop its own nuclear-powered submarines.

    A staffer in the office of People Power Party lawmaker Ha Tae-keung, who revealed the hacking attacks last week, said, "Most of the data stolen from Daewoo was related to submarines."

    The Defense Acquisition Program Administration admitted there was a hacking attack but denied that military secrets were stolen, saying the firewalls held out.

    North Korean hackers have persistently targeted Daewoo, which has been building all of the Navy's submarines. The Chosun Ilbo was unable to confirm the exact documents that were stolen, but sources said they wanted information on the new Dosan Ahn Changho, a 3,000-ton attack submarine that was launched in 2018 and is about to be handed over to the Navy.

    In 2016, hackers stole 40,000 files from Daewoo including 60 documents with classified information about the submarine's design, ballistic missile system and vertical launch system.
