Ostium said its investigation found the July exploit originated from compromised off chain infrastructure rather than a flaw in its smart contracts.Fraudulent BTC USD price reports allowed the attacker to drain 23.75 million USDC from the protocol’s OLP liquidity vault.The protocol said automated monitoring detected the attack, trading resumed on July 23, and user collateral remained unaffected.A recovery plan for affected liquidity providers is being finalized and will be shared in a separate update.
