Hackers from North Korea are reported to have stolen a large cache of military documents from South Korea, including a plan to assassinate North Korea’s leader Kim Jong-un.
Rhee Cheol-hee, a South Korean lawmaker, said the compromised documents include wartime contingency plans drawn up by the US and South Korea.
Plans for South Korean special forces were reportedly also accessed, along with information on significant power plants and military facilities in the South.
Mr Rhee sits on its parliament’s defense committee, and said some 235 gigabytes of military documents had been stolen from the Defence Integrated Data Centre, and that 80% of them have yet to be identified.
The hack took place in September last year. In May, South Korea said a large amount of data had been stolen and that North Korea may have instigated the cyber attack – but gave no details of what was taken.
