North Korean hackers thought to be behind $100m cryptocurrency heist

If confirmed, last week's attack would be the eighth this year - involving $1bn in stolen funds - that could be confidently attributed to North Korea

North Korean hackers are thought to be behind last week's theft of as much as $100m in cryptocurrency from a US company, as the regime steps up attempts to secure funding for its nuclear and ballistic missile programmes.

The assets were stolen on 23 June from Horizon Bridge, a service operated by the Harmony blockchain that allows assets to be transferred to other blockchains, three digital investigative firms have concluded.
