Aave fork lending project-Polter finance hacked due to price manipulation. Very very classic oracle issue.
As you can see from picture, BOO token price is very high. Why?
BOO token price is calculated using Spooky LP token state. This can be easily manipulated using flashloan.
At the beginning of the attack, hacker borrowed almost all BOO tokens from LP, that’s why BOO price was very high, he was able to deposit 1 BOO and drain all pools. Total loss is over $7m.
