I don't know if this applies to you, but did you connect your wallet to any sites? I don't really like connecting a wallet to deposit to a site, but that seems to be a fad these days. Feel like I remember someone getting scammed like this.
most common is fake airdrop claims in twitter he probably clicked some link and signed a message that drained his wallet
he knows nothing ... there nobody who can help him even Satoshi nakamoto or metalik will not be able to help Him
bye bye to that funds and dont sign any message or connect your wallet to any random sites next time or simply stay away from crypto
