Holy 157 million that's a huge amount. There is no way to freeze an address on ethereum, right? Because if they don't then there could be a massive blood bath on the alt market.
The address can't be frozen but some tokens can't lock the tokens that have already stolen by the scammers. Just take a look at how tether has already helped kucoin to recover 33 million dollars from there.
All of the exchange sites have already cooperated to trace the hackers and the hackers can't send the funds anywhere as it will always ask the KYC.
The hacker can be traced.
There's no way for the hacker to withdraw their money.
They already contacted majority of exchanges already to block the deposits of the hackers crypto addresses, so everyone is already watching. Yes they have assured that everything is covered by their insurance so this is reassuring their users already.
But what is scary is though the exploit come from the vulnerability of the private key or their wallets. How can the hackers were able to access that? We do hope that they will come up with a good root cause analysis so that this kind of exploits can be prevented by any exchange in the future.
