Ostium halts trading after $23.7M USDC stolen via oracle exploit in liquidity vault

Ostium, a trading protocol on Arbitrum, suspended all trading after an attacker exploited a compromised oracle signer key to fabricate price data and drain up to $23.7 million USDC from its liquidity vault. The attack caused a 72% drop in the vault's total value locked, with stolen funds converted to ETH and spread across wallets. Ostium has frozen trader funds and positions and is working with security experts to investigate and strengthen its systems before resuming trading. This incident highlights risks beyond smart contract audits, especially in oracle and key management infrastructure.
