Ostium links $23.75M USDC OLP vault exploit to offchain infrastructure breach, not smart contracts

Ostium said its investigation found the $23.75 million USDC exploit of the OLP vault was caused by compromised offchain infrastructure, not smart contract bugs or multisig issues. The attacker used fraudulent BTCUSD price reports to create artificial profits and withdraw funds before monitoring blocked further withdrawals. Trader collateral stayed secure as Ostium migrated systems and prepared a recovery plan for liquidity providers.
