Polymarket's UMA CTF Adapter exploited on Polygon as attacker siphons 5,000 POL every 30 seconds; losses top $520K

Polymarket's UMA CTF Adapter is being actively exploited on Polygon, with the attacker pulling roughly 5,000 POL about every 30 seconds. Total losses have surpassed $520,000, according to Santiment MCP and Claude. UMA reacted as the exploit unfolded, with $UMA sliding from $0.477 at 07:00 UTC to $0.462 by 09:00 UTC, a 3.3% drop. Over the same period, $POL was largely unchanged around $0.092, reflecting market differentiation between protocol-level risk in the adapter and POL's underlying token mechanics. Onchain investigators ZachXBT and Bubblemaps flagged the activity. Stolen funds have already been distributed across 15 addresses.
