I previously took advantage of Polymarket's deposit bonus promotion, but when I logged into my account recently I found that my money had been transferred out and someone kept placing bets. I registered through Gmail. On X, people are saying there's a recent vulnerability where hackers can directly access accounts using just an SSN. Right now I'm trying to reach customer service but they're ignoring me too. Everyone should log into their own Polymarket and check.
Where did you see the SSN vulnerability you mentioned? Could you share the specific source? That way everyone can better judge whether it's real or not.
For accounts that involve money and identity information, it's best not to use the same email to sign up for multiple platforms, especially not your primary Gmail. If it's true that an SSN alone can grant access, then the problem isn't just limited to Polymarket—it could also involve a KYC data leak. I'd suggest first checking whether you've used the same information on other platforms, and keep an eye out for anything unusual on your credit report. If customer service ignores you, try publicly tagging the official account on X—that's usually faster than email.
U.S. users may rely more on SSN for identity verification, so this kind of vulnerability would have a bigger impact; if an account is registered in another region, the verification method is different, and the risk points may also differ. But no matter where it is, deposit bonus promotions tend to attract a large number of accounts and are easily targeted.
Don't panic yet. Take screenshots of your login email, linked account details, and transfer records, then immediately change your Gmail password and enable two-factor authentication. After that, file an appeal through Polymarket's official channels—don't rely solely on email support.
