The DeFi protocol xWin Finance based on Binance Smart Chain was attacked by lightning loans. xWin Finance was exploited and the attacker gained about $270k. This incident was due to an invalid slippage control in the protocol, which is exploited in a flashloan to obtain extra xWin rewards. This incident was due to a bug in the internal _swapBNBToTokens() function of xWinFund contract which implements a price slippage control. However, the logic of slippage control is invalid. The hacker made use of this bug and gained rewards (in terms of 303,998.86 xWin tokens) from the contract to swap for BNB.
