Do not panic. Everything is back to normal.
MetaWin CEO Skel said the gambling site was hacked. $4 million stolen. Onchain sleuth ZackXBT revealed that the attacker moved the stolen funds to Kucoin and a HitBTC nested service. He also identified more than 115 addresses associated with the malicious actor.
If actually all the stolen were sent to kucoin and Hitbtc then there is every possibility to restore them back with the hope that they can also write to these two exchange to halt lock their account freezed the funds inside, so that they can't make any further withdrawal after trying to exchange those stolen coin into another coin and withdrawal them out.
If the scammers actually sent the funds to centralized exchanges like Kucoin and others then I think recovering the funds would be very easier compared to when the funds is sent to decentralized wallets where the funds can be very difficult to track. Sending stollen funds to exchanges like Kucoin is more easier to track than the ones sent to non custodial wallet and I believe the team would have written to the exchanges involved so they can track how every penny is being moved and where it is send to later. Casino hacks has been in existence for a long time and every casino team needs to work on their security to prevent something like this from happening.
