North Korean state-backed hackers have mounted a campaign to obtain secrets related to nuclear materials, military drones, submarines and shipbuilding in the UK and US, as intelligence agencies warned of a “global cyber-espionage campaign” targeting sensitive industries.

A joint notice from the US, UK and South Korea warned that the Democratic People’s Republic of Korea (DPRK) was using state-backed attackers to further the regime’s military and nuclear ambitions. It added that Japan and India had also been targeted.
