SEOUL, April 10 (Xinhua) -- A massive amount of military secrets have been leaked from the state-run defense agency under the South Korean Defense Ministry, an opposition lawmaker said Thursday.
Unidentified hackers drained confidential military information from the Agency for Defense Development (ADD) by infiltrating malicious codes and programs into its central servers, Rep. Kim Young-joo of the main opposition New Politics Alliance for Democracy said in an e-mailed press release.
More than 3,000 computers at the ADD were hacked, but it failed to recognize the cyber attack, Kim said, noting the agency reported the case to the police only after the lawmaker asked for confirmation of the leak.
According to the lawmaker, the leaked military intelligence included information on the mid-altitude unmanned aerial vehicle ( MUAV) of which the South Korean military launched developing to enhance reconnaissance capability against the Democratic People's Republic of Korea (DPRK).
The leakage also included documents on Shingoong, a portable anti-aircraft missile which South Korea has invested 70 billion won (68 million U.S. dollars) to develop, as well as Cheongoong or the mid-range surface-to-air guided missile.
The Defense Ministry said in the press briefing the claim of around 3,000 ADD computers hacked was not true as the agency has used a separately developed intranet, which completely blocks outside access.
The leaked documents were confirmed to be unclassified ones, which were exchanged between the agency and its subcontractors, the ministry said, adding the military was looking into the case.
