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.

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.
