One of Polymarket’s third-party vendors suffered a hack Thursday, the prediction market said, leaving its website vulnerable to an exploit that analysts said led to millions of dollars lost for users of the platform.
Ultimately, the hackers stole some $3 million worth of customer funds.
On-chain sleuths at Bubblemaps concluded that potential damage from the hack was largely contained, with less than 15 user accounts affected. The blockchain investigations firm did not immediately respond to Decrypt’s request for comment.
Some Polymarket accounts affected:
Polymarket said it is in the process of refunding impacted customers in full, and that the frontend issue has been contained and removed.
It is as of yet unclear what steps the prediction market platform can take to prevent such an exploit from happening in the future, given that it relies on some external, third-party businesses that are apparently directly involved in the site’s operation.
Both that exploit and today’s, however, point to the ability of hackers to infiltrate major companies on the margins, even when core protocols remain secure.
