The decentralized exchange Ostium suffered an $18 million exploit after an attacker manipulated oracle price reports. This incident is part of a broader trend of oracle and keeper-system vulnerabilities currently impacting the DeFi sector.
According to Blockaid's alert, the attacker leveraged a registered PriceUpKeep forwarder, a component of Ostium's automated infrastructure, to submit oracle price reports with future-dated timestamps. The manipulated reports created the appearance of profitable trades, which triggered an $18 million USDC payout from the vault.
