    Polymarket, a platform where people bet on future events, experienced a security breach that cost customers an estimated $3 million. Hackers injected malicious code into the website after breaking into a third-party vendor that Polymarket uses. This allowed them to steal money from customer accounts. Polymarket has announced it will fully reimburse all affected customers.

    If you use Polymarket, check your account immediately to see if any unauthorized transactions occurred.

    Stay one step ahead of scammers

    Weekly cybersecurity briefings for families. No spam, just the threats that matter and what to do about them.

    Even though the company promises reimbursement, you should verify your account status and follow any instructions Polymarket sends you. If you do not use Polymarket, this breach does not affect you directly. However, it illustrates risks that exist on any platform where you store money or financial information.

    If you are a Polymarket customer, take these actions now:

    1. Log into your account and review all recent transactions.
    2. Change your Polymarket password immediately.
    3. If you used the same password on other sites, change those passwords too.
    4. Enable two-factor authentication on Polymarket if available.
    5. Watch your email for official communication from Polymarket about reimbursement.
    6. Be alert for phishing emails pretending to be from Polymarket, as scammers often exploit breaches. This incident happened because a third-party vendor was compromised. Many websites rely on outside companies for various services, creating security weak points beyond their control. When choosing where to keep your money online, research the platform's security practices and read reviews. Never keep more money in an online account than you can afford to lose. Consider using a credit card instead of a debit card for online purchases, as credit cards typically offer better fraud protection.
