Five Exploit Transactions Drain More Than $303,000 From Ankr's Ethereum Bridge

Ankr's Ethereum bridge lost more than $303,000 in five exploit transactions. The contract remained unpaused after withdrawals referenced a small Optimism deposit that had already been redeemed. The withdrawal references involved a deposit on Optimism, while the affected service was Ankr's Ethereum bridge. In the described sequence, the deposit had been redeemed before withdrawals referred to it. The deposit was described as small, and the withdrawal references came after redemption. The five transactions together accounted for a loss above $303,000. That total is the stated amount across the exploit activity. The contract was still unpaused after the withdrawals.
