UPD1: It is also rumored to have additionally stolen BTT worth more than $ 3.5 million and TRX worth more than $ 17 million. Perhaps this will be announced later. After the withdrawal of ETH to unknown wallets from the exchange, BTT with TRX moved to unknown wallets.
UPD2: Funds in the amount of 342,000 ETH were stolen from the Upbit wallet, funds began to be received again, in different amounts, it seems from the exchange team. A logical question arises. Why replenish an already compromised wallet? Hacked wallet balance already - 4.726 ETH
