BNB Chain-based memecoin platform Four.Meme has suffered another security breach, this time losing approximately $120,000.
According to a report from SlowMist CISO 23pds, the attack was not a result of vulnerabilities in Four.Meme’s smart contracts but rather a leaked private transaction related to liquidity addition on PancakeSwap.
The hacker reportedly exploited this leaked data to execute a “black sandwich” attack, a sophisticated technique that manipulates transaction execution to siphon funds.
While the exact mechanism of the attack remains unclear, speculation suggests that a tool commonly used for Binance Smart Chain (BSC) transactions, BSC Builder, may have been compromised, potentially exposing confidential transaction details.
Second Major Hack in Just Over a Month Raises Security Concerns
This attack comes just over a month after Four.Meme suffered another hack in which $200,000 was stolen.
The recurrence of such breaches has raised concerns about the platform’s security infrastructure and the increasing risks faced by projects operating on the BNB Chain.
Crypto hackers have become more sophisticated, moving beyond direct smart contract exploits to targeting backend infrastructure and transaction confidentiality.
The fact that both attacks happened within a short time frame has shaken investor confidence, with many in the community urging Four.Meme to take more rigorous security measures to prevent further incidents.

Speculation Grows Over Possible Causes and Infrastructure Vulnerabilities
Unlike typical smart contract exploits, this attack appears to have resulted from the exposure of sensitive transactional data, raising serious concerns about the security of blockchain infrastructure beyond smart contracts.
Some experts suspect that BSC Builder, a tool used to create and manage transactions on the Binance Smart Chain, may have been compromised.
If confirmed, this could pose a major threat to other projects relying on similar infrastructure. The use of a “black sandwich” attack suggests that the hacker manipulated the liquidity transaction, allowing them to front-run and extract funds in an advanced manner.
However, without definitive proof of how the transaction data was leaked, the incident highlights the growing need for stronger security measures at all levels of blockchain ecosystems.

Crypto Community and Industry Response to Security Threats
The repeated security breaches on Four.Meme have prompted discussions about the broader security risks in decentralized finance (DeFi).
While the team has been swift in responding to the attacks, community trust has been shaken, with investors demanding additional security protocols to prevent future incidents.
The incident also underscores the increasing need for DeFi platforms to implement multi-layered security measures, including encrypted transaction signing, enhanced wallet security, and infrastructure audits.
As investigations continue, security experts will need to determine the exact cause of the breach to prevent similar exploits in the future.
The attack on Four.Meme serves as yet another reminder that DeFi projects remain prime targets for increasingly sophisticated cybercriminals.
Recent Crypto Hacks Highlight Growing Security Challenges
Four.Meme’s hack is just one of several high-profile security breaches in the crypto industry in recent weeks.
Dubai-based crypto exchange Bybit recently suffered a staggering $1.44 billion Ethereum hack, marking the largest crypto theft in history, although user funds reportedly remain intact.
In another major breach, the Infini platform’s smart contract was exploited, leading to the theft of over 17,696 ETH (worth $49 million).
In response, Infini has pledged full reimbursement for affected users while investigating the possibility of insider involvement.
These incidents highlight the growing threats facing crypto platforms, reinforcing the need for improved security practices across the industry.
