According to a post retweeted by 23pds, SlowMist's chief information security officer: "Four.Meme was hacked and lost about $120,000. None of the contracts were vulnerable. The root cause was the leakage of transactions that Four.Meme add liquidity to PancakeSwap. The hackers somehow got hold of these private transactions (probably BSC Builder was hacked) and bundled them for a sandwich attack."
