The MEV Bot (0x05f016765c6c601fd05a10dba1abe21a04f924a5) was exploited and lost about 1k ETH! The core reason is that the 0xf6ebebbb function used to trigger arbitrage in the contract lacks authentication. The attacker calls this function to exchange the tokens in the contract into the pool on curve, and then uses funds of the flash loan to reverse exchange and obtain profit.
