Navy Shipbuilder Suffers N.Korean Hacking Attack

Military authorities are investigating a suspected North Korean hacking attack on Hanjin Heavy Industries and Construction, which builds warships for the Navy.

A military source on Tuesday said Hanjin appears to have been hacked on April 20, and military authorities are conducting an investigation into whether any military secrets were leaked and whether North Korea was involved.

Hanjin has built landing ships, patrol vessels and high-speed boats for the Navy and its intranet apparently contains sensitive military information.

Military officials believe North Korea's General Reconnaissance Bureau is responsible for the attack. The bureau has around 3,000 to 4,000 hackers under its wing.
