Sandwich attack, oracle price manipulation
On Tuesday September 3rd, samczun, the security researcher who found the critical bug in 0x, alerted us to an exploit leveraging our implementation of Kyber’s price feeds. We have confirmed that the exploit exists and has never been used. The exploit was immediately patched. The premise of the attack involved manipulating the price feed with a sandwich attack at the time of taking out the loan. This was an attack vector that both ourselves and our auditors did not detect. Despite the fact that great pains had been taken to protect against price feed manipulation, most of that effort was spent focused on the liquidation process.
