i think there is a way to retrieve those coins but as long it's deposited into binance exchange
because i saw an article before that if those coins deposited into binance then their account will be locked with the balance will be sent back to upbit
If these coins are sent to binance then the funds will probably return to Upbit again, but the thieves always have a sense so people will not know where they are going to sell them, even though Upbit after hiring a specialist to research the tx then I think it does not exist for its purpose, the token will never return.
