Operational Plan 5015 relates to “the latest Seoul-Washington scheme to handle an all-out war with Pyongyang, which reportedly contains detailed procedures to ‘decapitate’ the North Korean leadership,” while operational Plan 3100 is Seoul’s plan to “respond to the North’s localised provocations,” the news agency said.

“Also among them were contingency plans for the South’s special forces, reports to allies’ top commanders, and information on key military facilities and power plants,” Yonhap added, referring to Cheol-Hee’s claims.

According to the South Korean lawmaker who cited unnamed defense officials as being the sources of information on the hack, 235 gigabytes worth of military documents were taken, but nearly 80 percent of the contents of the documents is yet to be identified.
