The cryptocurrency exchange Bybit has fallen victim to an attack resulting in the theft of digital assets valued at approximately £1.24 billion. Experts believe this to be the largest theft in the sector's history.

North Korean cyber criminals are feared to have carried out the “worst hack in history” after a $US1.19 billion ($2.36 billion) billion crypto heist was uncovered.

On-chain sleuthing linked Friday's $1.4 billion hack of crypto exchange Bybit to North Korea's Lazarus Group, Arkham Intelligence said.
