US, S. Korea, Japan unite against North Korea's cyber threats.

The US, South Korea, and Japan have expressed deep concern over North Korea's "malicious" cyber activities to support its weapons programmes. Crypto currency funds stolen by North Korean hackers have been a key source for financing the sanctions-stricken country's weapons programmes. Amid North Korea's rising nuclear and missile threats, South Korea's nuclear envoy held talks with his US and Japanese counterparts in Seoul this week and condemned the isolated country's weapons tests. Japan on Friday announced a two-year extension of its trade ban on North Korea, with exemptions for humanitarian reasons.
