North Korean hackers have stolen $1.5 billion in cryptocurrency in a single heist, making it the largest crypto hack on record, security experts told CNN.

The hack that rocked the crypto market and saw most prices tumbling was called the "largest crypto theft of all time, by some margin," by Elliptic's Tom Robinson, co-founder and chief scientist. "The next largest crypto theft would be the $611 million stolen from Poly Network in 2021. In fact it may even be the largest single theft of all time."

Following the revelation Friday from cryptocurrency exchange firm Bybit that hackers stole digital tokens worth about $1.5 billion – in what may be the biggest crypto heist of all time – CEO Ben Zhou wrote on X Sunday that it has replenished its reserves. Bybit was able to do this through a mix of emergency loans and large deposits.
