To be honest right now, everyone is affected, Bybits Jan says

Bybit, a cryptocurrency exchange, reported a suspected hack of one of its Ethereum cold wallets, resulting in the theft of approximately $1.4 billion worth of Ethereum. This amount represents about 70% of Bybit's total Ethereum holdings. While the exchange claims other assets and wallets are secure, all users are currently affected as Ethereum withdrawals have been paused. Bybit has stated it will not buy Ethereum on the open market to replace the stolen funds, although some partners are helping to process withdrawals. Retail withdrawals of other cryptocurrencies are reportedly continuing normally.
