MEME internal market has been emptied! Hackers exploited the PancakeSwap vulnerability to steal Liquidity funds from the emerging meme coin Four.meme

Blockchain security company SlowMist issued a security alert today (3/18), exposing an attack on the Four.meme project. Hackers successfully bypassed transaction restrictions through vulnerabilities in the PancakeSwap Smart Contract mechanism, stealing Liquidity funds. This also cast a shadow over the recently heated Binance meme layout in the past few days.

Analysis of attack methods: Pre-purchase of unlisted tokens to bypass trading restrictions

According to SlowMist's analysis, the attacker purchased a small amount of new tokens through the function 0x7f79f6df in the pre-launch phase of multiple new tokens on the Four.meme platform within (, allowing the hacker to acquire a certain amount of tokens before the tokens are officially listed on PancakeSwap, laying the foundation for subsequent attacks.

Critical Vulnerability: Deposit tokens into an address for a non-existent trading pair

The attacker used the 0x7f79f6df function to send the new token to a PancakeSwap trading pair address that has not yet been created. Because the trading pair does not exist, this allows the hacker to create the trading pair and add Liquidity directly without the need to transfer the new token separately.

This operation successfully bypassed MODE_TRANSFER_RESTRICTED (restricted transfer mode), which was originally intended to restrict transactions before the token was officially launched. In this way, attackers were able to bypass the preventive measures of the Four.meme project.

Liquidity theft: Profiting from price manipulation

After establishing the trading pair, the attacker added Liquidity at an abnormal price, enabling them to obtain more funds when the price did not meet market expectations. Ultimately, the hacker successfully stole the Liquidity funds in the pool, causing losses to investors.

Security warning: Smart Contract development needs to strengthen prevention mechanisms

This incident once again highlights the risks of Smart Contract vulnerabilities, especially the security issues in Liquidity pools and trading pair creation mechanisms on decentralized exchanges (DEX). Experts suggest that development teams should take the following measures to reduce risks:

Review contract functions: Ensure that special functions (such as 0x7f79f6df) are not maliciously exploited.

Enhanced Liquidity control mechanism: limiting the creation conditions of trading pairs to prevent tokens from being maliciously injected prematurely.

Implement trading monitoring: Identify abnormal trading behaviors using AI and real-time monitoring tools.

The cryptocurrency market presents both risks and opportunities. Investors should always pay attention to the security of the projects to avoid unnecessary losses.
