The South Korean military counter-espionage service has begun an investigation into an alleged North Korean hack into Hanjin Heavy Industries & Construction Co., a major builder of naval warships, the Korean Yonhap News Agency first reported Tuesday.
“After identifying signs that Hanjin Heavy Industries may have been hacked on April 20, the Defense Security Command is currently leading a security investigation into whether any military secrets were leaked and whether North Korea was involved,” official sources said in the report.
Although North Korea may have been involved in the alleged hack, “we are not absolutely sure at this stage,” the source added.
Hanjin has built the latest frigates and amphibious assault vessels for the South Korean navy.
