Investigation revealed that BingX, & Phemex hacks were also connected to the same cluster as Bybit's, confirming the threat actor’s identity as the Lazarus group.

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.

Cryptocurrency exchange Bybit said last week hackers had stolen digital tokens worth around $1.5 billion, in what researchers called the biggest crypto heist of all time. Bybit CEO Ben Zhou said the crypto was taken from a "cold wallet" - a digital wallet usually stored offline and so supposedly more secure - that was used for ether tokens.
