[SlowMist: Eldel Finance Lost Approximately $350,000 in Attack Incident] According to SlowMist Alert, Eldel Finance suffered a loss of approximately $350,000 due to an attack. The root cause of the vulnerability lies in the `latestAnswer()` function of the price oracle, which reads the `convertToAssets()` function of the ERC4626 vault. The vault's `totalAssets()` directly uses the balance of the underlying assets, allowing the attacker to manipulate the price by directly transferring and donating assets. The attacker utilized a flash loan in conjunction with donation attacks to manipulate the oracle price, stealing approximately $350,000 and some reserves from the Aave Pool. The attacker's address is 0x58428161bb55c14a413945f06cbdec157f411c76, and the affected contracts include the price oracle and the ERC4626 vault.
