Are you talking about $25 or $25k? If it was $25k, then why would you let it go without doing anything? It is easy to access the account at Duel.com by just knowing the password since they don't send authentication email for new login. You should add some evidence here. Is there any unknown active session on your Duel account? Duel team should block the account on which the tip was sent.
You should change the password at all other casinos where you used it. Adding the 2FA would be the best thing.
I'm talking about 25.000 USD. I didn't know there were active unknown sessions.

My whole balance got tipped to random burner accounts and was also withdrawn from Duel.
You have a slim chance here, because it has to do with just your account being hacked, however, all hopes are not lost, you can try going through the transaction history on the account and track the transaction hash linked to the withdrawal, to know which address the funds went to, if you're lucky, the money would be in an exchange owned address, if so, contact the exchange's support team and talk to them about this hack with all evidence shown on blockchain, supports are fully ready to respond to users regarding the recent increase in malicious activities targeting crypto users, maybe the account holding the funds would get frozen from there.
Also discuss with the Duel support team about this hack, maybe they'll find the loophole about the password leakage, could you point out how exposed your computer has been lately?
I don't have any access to the transactions since my balance got tipped away to random burner accounts. These accounts have withdrawn the funds so only Duel.com knows where the funds went to. Duel said they can't give any information and only to local authorities if I file a complaint.
I could find them on-chain:

https://solscan.io/account/B8vQvywnHLo2Uy3ov8nJfK9Zhvz9wn4jvvHaZriuBoUCMy password probably has been leaked somewhere. I don't even remember the password I used to login. But now I changed it and setup 2FA. It was dumb not having 2FA.
Anyway to proceed with this or just lost case?
I'm assuming this is about duel.com, if not mentioned that full name of the casino. Anyway, if you are thinking about the casin possibly compensating you for what happened, I don't know if they will. Because judging by how they responded to this
thread according to the OP, their support will basically say it is out of their hands.
I'm not expecting a kind of compensation. Just curious if there are any steps to take. Since filing a police report in my country is pretty useless and won't result in anything.
