Over the past 30 days, private key compromises accounted for 43% of reported exploit losses, making them the leading attack vector, according to DefiLlama. Fake proof exploits accounted for 10%, followed by reverse MEV honeypots at 8%, which present deceptive trading opportunities to lure and manipulate automated trading bots.

About a month before Polymarket’s latest attack, the prediction market disclosed a separate $600,000 exploit that was traced to a six-year-old private key used for internal top-up operations. Josh Stevens, Polymarket’s vice president of engineering, said the platform’s contracts and user funds remained safe and that all permissions tied to the key had since been revoked.
