I guess centralize exchange does have a good side, if the hacker had liquidate this funds on a decentralized exchange perhaps it would not have been easy to recover the funds. I wonder what the hacker was thinking doing a direct sale on binance! i soon the authority will uncover the identity soon.
With new like these, those hackers will learn not to trust any CEX. I'm not sympathetic to those hackers but with what CEX are doing today, they could actually just accuse someone are then hold the funds with them until they find something to link the funds to.
80% is huge. Authorities can never get it without CEX help. Good job for Binance. Little have been said about recovering the funds and who are behind it of course so Binance kept their names private, they only will make it public if necessary.
