Harvest Exploited

1/ Here is a breakdown of the @harvest_finance attack. Ref ethtx.info/mainnet/0x9d09… 1. Swap 11.4m USDC to USDT -> USDT price up 2. Deposit 60.6m USDT into Vault 3. Exchange 11.4m USDT to USDC -> USDT price down 4. Withdraw 61.1m USDT from Vault -> 0.5m profit 5. Rinse and repeat

ethtx.infoEthtx.info Analysis

Yield Aggregator Harvest Finance was exploited today as a user used a flash loan from UniswapV2 to initiate an oracle attack on the USDT vault for Harvest. By manipulating the price of USDT in the Curve Y pool, the attacker was able to withdraw more USDT from the vault than they had put in, and this cycle was repeated to make around $25M in profit for the attacker.

In an interesting action reminiscent of the EMN ape-ra, the attacker sent back about $2.5M to Harvest.
