AFAIK they gained access to a DevOps guy's laptop with too many privileges and just made a bunch of withdrawals into their own wallets, so they have their keys.
The only hope is that most of it gets frozen in some way or another, but if even only 1% gets through they'll still have made about $65M
This makes no sense to me. Why would a DevOps developer have access to the customer accounts including their private keys?
How can you "freeze" Bitcoin transactions? If you have the private keys you can always make transfers etc.
If they get away with $6.5 Billion Binance is done for. There's no way they'll be able to repay their customers.
