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Yes, only beginners could do this, who do not understand that their money will be blocked and withdrawn after applying to Metawin.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.
