Someone Drained Polymarket's Ops Wallet at 5,000 POL Every 30 Seconds. It Took Hours to Stop.
A compromised private key let an attacker automate withdrawals from Polymarket's UMA CTF Adapter on Polygon. ZachXBT flagged it first. Losses passed $700,000 before the team responded. Polymarket says user funds are safe. The attacker has already split the proceeds across 15 wallets.
