The Federal Bureau of Investigation (FBI) asked for crypto industry help in tracking and blocking transactions intended to launder the $1.5 billion stolen from Bybit by North Korean hackers.

On February 21, 2025, Bybit, one of the largest crypto exchanges, suffered an attack when hackers exploited a routine transfer from a cold wallet to a warm wallet—a standard process in crypto exchanges to ensure liquidity. The attackers managed to intercept this transfer, diverting approximately 400,000 ETH ($1.5 billion) to unknown addresses.

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.
