ROK Police Say North Korean Hackers Did Not Access Classified Defense Documents

This is why classified information is not stored on an unclassified network because it is so easy for hackers to get access to it:

Hours after police revealed that North Korea gained access to a host of defense-related documents during a hacking attack in February, the South Korean military asserted that no military secrets were included in the leaked documents.

A military official said on Monday that most of the 42-thousand documents stolen from South Korea’s SK Networks and Korean Air by the North are already open to the public.

The leaked documents reportedly include the design map of the wing of the U.S. F-15 fighter jet and photos of parts of a medium altitude unmanned surveillance vehicle.

The compromised data of the U.S. F-15 fighter jet is said to be simple specifications of the jet’s external design such as its length and width, and has no relevance to South Korea’s F-15K.  The military said that the core part of the design of the medium altitude unmanned surveillance vehicle was not leaked.  [KBS World Radio]
