The nation has additionally said it proposes a joint examination with the U.s. on the assault and if the U.s. does not concur, North Korea cautions of "grave results," state media says.
The declaration comes as a reaction to the FBI's announcement saying it has enough data to "reason that the North Korean government is capable" for the activities.
The agency said its discoveries were the aftereffect of an examination that included different offices and orgs, and were situated partially on specialized investigation of the malware utilized as a part of the assault.

Despite the fact that the FBI has seen a wide mixed bag and expanding number of digital interruptions, the ruinous nature of this assault, coupled with its coercive nature, separates it.
"North Korea's activities were expected to exact noteworthy mischief on a U.s. business and stifle the right of American subjects to communicate. Such demonstrations of intimidation fall outside the limits of satisfactory state conduct."
