Polymarket halts trading for an hour after DebugBear vendor breach
Polymarket paused trading on its international platform for nearly an hour Thursday after discovering that software from third-party vendor DebugBear had been compromised. The company said affected users would be fully reimbursed and referred the incident to UK law enforcement, while The Block reported roughly $2.65 million in crypto was drained from user wallets, citing Arkham data. Polymarket's US platform was reportedly unaffected, and trading resumed around 3 p.m. ET.
GoKawiil's interpretation of the reporting above, not reported fact.
The breach highlights how third-party software vendors remain a weak link for crypto platforms, since attackers can bypass a company's own defenses by compromising tools it relies on. Polymarket's pledge to reimburse users may help contain reputational damage, but the unconfirmed loss figures and ongoing law enforcement referral suggest the full scope and resolution are still unclear.
- Polymarket halted international trading for nearly an hour after a vendor compromise
- DebugBear, a web analytics tool, was reportedly the entry point for attackers
- Polymarket pledged full reimbursement while an estimated $2.65 million was reportedly siphoned, per The Block/Arkham
