Yearn Finance: Investigation Update

On April 14th, it was reported that Yearn Finance posted on Twitter the progress of the investigation into the attack, stating that as previously stated, the root cause of the attack on Yearn was a vulnerability left in the iEarn USDT (yUSDT) token contract. This vulnerability exists in multiple versions and leads to multiple Curve pools (y, busd, pax) being exploited and exhausted. The liquidity providers who deposit LP tokens into downstream protocols are still affected, including users who encapsulate the Yearn v2 vault (2) and the old version v1 vault (2) of these affected LPs. In previous tweets, Year stated that the current version of Year v2 Vaults is not affected.
