The DeFi protocol AutoShark Finance on the Binance Smart Chain was attacked by lightning loans. The main reason was that the exchange mining function was used by hackers in a series of transactions. Hackers could use lightning loans to occupy most of the mining pool (to make up for exchange losses/fees) ), at the same time, the exchange fee reward was obtained, and a total profit of 3.18 million FINS was obtained. Afterwards, the hacker exchanged FINS for 1,388 BNB (approximately US$580,000). Attack method (per SlowMist): Flash loan attack. Reported loss: 3,180,000 FINS.
