This is why I am not a fan of BTC being "wrapped" on to other chains. Luckily it seems that either this hacker is a white hat or they are honestly really smart in thinking that $80k for Binance isn't much and is something they could get away with.
On a side note, I find it hilarious that the funds have been tracked going in and out of Tornado Cash. It goes to show that these mixers are not what they once were and how governments need to stop thinking they are this impossible-to-crack black box.
