Blockaid: Ankr cross-chain bridge attacked, approximately $292,000 stolen

Ankr's Ethereum cross-chain bridge was exploited on November 9, with roughly $292,000 in assets drained across about five transactions, according to Blockaid monitoring. The attacker submitted five withdrawal calls to the bridge, using a small deposit on Optimism to unlock the bridge's entire locked asset balance to a new wallet. The incident matters because it again highlights bridge security risk, where a minor deposit on one chain can trigger a full-balance release on another. Blockaid noted the attack was still ongoing at the time of its alert. What to watch next is whether Ankr pauses the bridge, confirms the full loss figure, and outlines reimbursement plans for affected users.
