North Korean hackers reportedly stole South Korean classified military documents from the intranet of South Korea’s Defense Ministry, including a top-secret plan to assassinate the DPRK dictator Kim Jong-un, wartime contingency plans of the US and South Korea, and reports to the allies' senior commanders, BBC reported.

Details of the hacked information

North Korean hackers broke into the system in the fall of 2016, but the report about it came out only last Tuesday. Defense officials previously said that no important information had been hacked. North Korea refused to take responsibility for the hack and accused South Korea of "fabricating" the claims.

Around 235 gigabytes of military documents were stolen, and about 80 percent of the hacked information hasn’t been identified, FOX News reported. Officials were able to get the details of only approximately 10,700 documents.

Yonhap news agency of South Korea reported that the DRPK targeted government websites and facilities of the South. North Korea possibly has specially-trained hackers overseas. According to officials, the documents submitted to Rhee Cheol-hee, a member of the country's legislature, were hacked from the country's defense ministry database.

Among them was the U.S.-South Korea military strategy for the Peninsula conflict, OPLAN 5015, the planned response to any acts of the DPRK aggression, the Independent reported.

The stolen information included plans for special forces and information about South Korean military bases.

The Peninsula situation is worsening

Last month, President Donald Trump claimed in his speech at the UN that the US would destroy North Korea if necessary, announcing that Kim Jong-un "is on a suicide mission." Trump also hinted that military actions could start any minute if the US would have to defend itself or its allies.

Last weekend, President Trump wrote on his official Twitter account that "only one thing will work" with North Korea after his ancestors had spent 25 useless years for peaceful negotiations with the DPRK. Trump did not disclose what this thing is.

On October 10, Pentagon spokesman Army Col. Rob Manning announced that "we are confident in the security of our operations plans and our ability to deal with any threat from North Korea." In September, North Korea carried out its most powerful nuclear test after five previous missile tests which had alarmed the world.
