LONDON/WASHINGTON (Reuters) - An elite group of North Korean hackers secretly breached computer networks at a major Russian missile developer for at least five months last year, according to technical evidence reviewed by Reuters and analysis by security researchers.
Reuters found cyber-espionage teams linked to the North Korean government, which security researchers call ScarCruft and Lazarus, secretly installed stealthy digital backdoors into systems at NPO Mashinostroyeniya, a rocket design bureau based in Reutov, a small town on the outskirts of Moscow.
