348 North Korean hackers ‘could kill’, warns key defector

Speech Materals


North Korean hackers are capable of attacks that could destroy critical infrastructure and even kill people, a high-profile defector has warned.

Speaking exclusively to BBC Click, Prof Kim Heung-Kwang said the country had around 6,000 trained military hackers.

The warning follows last year’s Sony Pictures hack – an attack attributed to North Korea.

Korean technology expert Martyn Williams stressed the threat was only “theoretical“.
Prof Kim has called for international organisations to step in to prevent North Korea launching more severe attacks.
