BNB-based memecoin launchpad Four.Meme was attacked. According to the SlowMist security team’s analysis, the attacker purchased a small amount of tokens before launch through the 0x7f79f6df function of Four.Meme, and used this feature to send tokens to a specified PancakeSwap Pair address that had not yet been created. This allowed the attacker to create the Pair and add liquidity without needing to transfer the yet-to-be-launched tokens to the Pair, bypassing the transfer restrictions (MODE_TRANSFER_RESTRICTED) that applied before the Four.Meme Token launch. Ultimately, the attacker was able to add liquidity at an unintended price to steal pool liquidity. Attack method (per SlowMist): Price Manipulation. Reported loss: $ 19,500.
