On June 17, 2023, Midas Capital's HAY/BUSD pool on BSC was exploited for $340K-$600K via a rounding error in cToken redemption logic. The attacker crafted positions that rounded down to 1 wei, repeatedly exploited the error with minimal deposits and flash-loaned ANKR collateral to withdraw disproportionately large sums.
