North Korean hackers have obtained a large amount of documents related to South Korean and U.S. military action, according to a report from the BBC. The hack reportedly happened in September 2016, and the documents included a plan to kill North Korean leader Kim Jong-un, U.S.- and South Korea-authored wartime contingency plans, plans for South Korean special forces, and reports to ally senior commanders, Foreign Policy reports.
Defense Secretary James Mattis on Monday said that the “U.S. Army needs to be ready” in case diplomacy with North Korea fails.
“Now, what does the future hold? Neither you nor I can say. So there’s one thing the U.S. Army can do, and that is, you have got to be ready to ensure that we have military options that our president can employ, if needed.” Mattis stressed.
According to South Korean officials, the hack could contain hundreds of thousands of documents, and most of them are still not identified. Around 80 percent of the 235 gigabytes of military documents taken from South Korea’s Defense Integrated Data Center is unknown, Foreign Policy adds. Military facility and power plant information was also stolen, according to the BBC report. South Korea’s defense ministry has refused to comment on the hack, the BBC said.
