1/x @AutoSharkFin The swap mining feature was exploited in a flurry of txs to gain the reward of 3.18M FINS tokens, which are then immediately swapped to 1,388 BNB (with roughly $581K). 
2/x The hack is made possible due to the relatively low pool liquidity so that the hacker can use flashloans to occupy the majority of pool share (to recover swap loss/fee) while still enjoy the sizable "swap fee reward” (increased from each huge swap).
3/x To illustrate, we use one example hack tx (bscscan.com/tx/0x640ce34ce…) with 100+ swaps back-and-forth to get 15K FINS rewards, which are then swapped to get 121 BNB as profit. Note the swap fee is still largely obtained by the hacker due to the owned majority pool share.
