The hackers don't seem to be very smart because they sent the funds to a CEX so they could be traced quickly.
Yes, only beginners could do this, who do not understand that their money will be blocked and withdrawn after applying to Metawin. I would not be surprised if they were verified on Kucoin using their real documents and, accordingly, their identities can be identified, and after contacting the police, they will certainly be brought to justice.
Kucoin ask KYC to all of its users so provably that identity of that hacker will be reveal once investigation will happen. What makes me curious to know why those hackers decide to sent those stolen funds on a KYC compliant platform. I don't know if they are totally noob hacker or there's something wrong happening like the hackers used those verified accounts used by other people which they sold to random people online. Hopefully this assumption is not happening here and we can see those hackers get jailed for this crime they do.
Note:
Starting from August 31, 2023 (UTC), new users must complete Identity Verification in order to use KuCoin's products and services.
For users who registered before August 31, 2023 (UTC) but have not completed standard Identity Verification before then, they will only be able to use the remaining services: selling cryptocurrencies, closing futures contracts, closing margin positions, redeeming from KuCoin Earn, and redeeming ETFs. During this time, they will not have access to deposit services (withdrawal services will not be affected).
https://www.kucoin.com/support/360015102254I think the hacker can be easily tracked. This is because new Kucoin rules, from August 2023, require new users to verify their identity to use the deposit feature. It's been reported that the hacker deposited some of the stolen funds to Kucoin. This raises the possibility that he has a verified account there. The only problem is that if he rented others' accounts to launder his money.
