North Korea's hacking capabilities are "beyond imagination," one former computer expert for the North told ABC News in the wake of Tuesday's report that the nation had stolen secret intelligence documents, including the U.S.-South Korean war strategy.

Secret intelligence documents and photos unilaterally collected by the U.S. military were among the stolen cache of South Korea’s classified documents by North Korean hackers, but the totality of what was stolen remains unknown, according to South Korea’s ruling Democratic Party lawmaker Lee Cheol-hee.

Malware contamination of the intranet server of the cyber command that occurred in September last year was confirmed by the South Korea’s Defense Ministry in May but this is the first glimpse of the scope of the damage.
