North Korean hackers broke into a South Korean defense contractor's computers and stole submarine blueprints and other classified military information, according to a South Korean lawmaker.
Kyung Dae-soo, a member of South Korea's hawkish Liberty Korea Party, revealed Tuesday that North Korea was most likely behind a hacking breach into Daewoo Shipbuilding & Marine Engineering Co. in April.
“We are almost 100 percent certain that North Korean hackers were behind the hacking and stole the company’s sensitive documents,” Kyung told Reuters.
The hackers stole 60 classified documents that included blueprints and data for submarines and different weapons systems, according to Kyung. The latest hacking revelation comes weeks after it was disclosed that a similar hack last year allowed North Korea to steal confidential U.S.-South Korean military information including a plan to take out leadership in Pyongyang in the event of a war.
Kyung said that some of the information pertained to submarine-launched missile technology. North Korea has a fleet of submarines and tested a submarine-launched nuclear-capable ballistic missile last year. Some experts believe that North Korea’s submarines aren’t particularly reliable or advanced, however.
There have been recent reports that North Korea appears to be building its biggest submarine capable of launching nuclear missiles.
Daewoo is responsible for building 17 submarines and 44 warships for South Korea, according to the Wall Street Journal Tuesday.
Hackers also stole Aegis missile defense technology information. Aegis is a missile defense system designed to take out airborne missiles. The system is also employed by the U.S. Navy.
