Taking a look...

ethtx.info/mainnet/0x8bb8…

This is the second attack whish uses multiple flash liquidity,
flash swaps via Uniswap and flash loans via dYdX

We will see very complex things via @AaveAave V2 batch flash loans :)
Quite interesting the attacker asked 3 loans via flash swaps to 3 different pools on Uniswap

WETH-WBTC 90k
WETH-USDC 82k
WETH-USDT 96k

It's definitely a batch flash loan via flash swaps!

And this is just the beginning...
And other two loans from dYdX

76k ETH and 2.9m DAI

continuing...

Argh! No 😥
Evil jars deployed during the attack and passed in the swapExactJarForJar, investigating more on this

etherscan.io/address/0x75aa…

etherscan.io/address/0x02c8…

The are sensible ops executed in that method (e.g. approve, withdraw etc).
In addition in the second invocation for swapExactJarForJar there were passed a target and doing a delegate call to CurveProxyPool 😢

Really complex and is not using at all FlashLoans!
