It's really stupid to hack a platform and move stolen fund to centralized exchanges. Hackers in this case maybe think that they can deposit and withdraw their fund quickly from centralized exchanges while Metawin team are sleeping.
We can’t say for sure if they’re really that clueless unless they get caught. Maybe they're using fake IDs or even trying to hack into the exchanges' systems to get their accounts verified. As far as I know, KuCoin implemented face recognition for KYC back in August 2023. On the other hand, HitBTC’s KYC process is pretty straightforward - it just requires you to upload an ID to the system.
