Four.Meme resumes operations after $120K sandwich attack

Four.Meme, a memecoin launch platform on the BNB Chain, has resumed operations following a sandwich attack that resulted in a loss of around $120,000. The platform announced on March 18 that its launch function was back online after a thorough security inspection. The attack involved exploiting a pre-launch vulnerability where the hacker managed to manipulate the market by pre-calculating the address for a liquidity pool’s trading pair. Through one of the platform’s functions, they bypassed token transfer restrictions to acquire tokens and then waited for Four.Meme to add liquidity before siphoning off the funds. Blockchain security firms ExVul and CertiK detailed that the attacker sent an imbalanced amount of un-launched tokens to the pair addresses and later sold them for profit, netting at least 192 BNB. This incident marks the second attack on Four.Meme within two months, highlighting ongoing security challenges in the crypto industry.
