Evolving Chinese cyber threat 'should worry us all': U.K. cyber head

LONDON -- China and North Korea are among the world's most worrisome countries in terms of cybersecurity threats, but that is not the full extent of the risks, the head of the British government's National Cyber Security Centre (NCSC) said in an interview.

"Increasingly, we're worried about the proliferation of cyber challenges, which allow any country in the world to purchase cyber, malware or other challenges to hit us or businesses in our countries," the NCSC's COO and interim CEO Felicity Oswald told Nikkei.
