[Ostium Attacked, Attacker Exploits Fake Prices to Arbitrage $23.75M USDC] According to an official report from Ostium, the attacker breached the off-chain price reporting system's permissions and submitted fake prices of $5,000 and $60,000 to the BTC-USD market. Starting with 100 USDC, the attacker executed 8 transactions within 5 minutes to siphon $23.75M USDC from the OLP vault. The incident was caused by a lack of multi-party approval mechanisms in the off-chain infrastructure. The stolen funds have been converted to ETH and laundered through Tornado Cash.
