最先进的三明治攻击目标是四分之一。

分散金融（DEFI）的世界虽然充满创新和潜力，也是一个战场，安全脆弱性

In the burgeoning realm of decentralized finance (DeFi), innovation often outpaces security, creating a battleground where vulnerabilities can be ruthlessly exploited. Recently, Four.Meme, a launch platform for memecoins built on the BNB Chain, fell victim to a sophisticated sandwich attack, resulting in an estimated $120,000 loss and the temporary disruption of its operations.

在蓬勃发展的权力金融领域（DEFI）中，创新通常超过安全性，创造了一个战场，可以无情地利用脆弱性。最近，Four。最硕士是建立在BNB链上的Memecoins的发射平台，成为了一场精致的三明治袭击的受害者，估计损失了120,000美元，并暂时破坏了其运营。

This incident, meticulously analyzed by web3 security firms ExVul and CertiK, serves as a stark reminder of the ongoing challenges in securing blockchain-based applications.

由Web3安全公司精心分析的这一事件Exvul和certik对此有了明显的想法，可以提醒您确保基于区块链应用程序的持续挑战。

Four.Meme, a Rising Star in the Memecoin World

fout。

Four.Meme has emerged as a key platform for launching memecoins on the BNB Chain. Memecoins, fueled by community sentiment and viral marketing, have become a significant part of the cryptocurrency landscape. Platforms like Four.Meme provide the tools and infrastructure for developers and communities to create and launch these tokens.

Four.meme已成为在BNB链上启动Memecoins的关键平台。在社区情绪和病毒式营销的推动下，Memecoin已成为加密货币景观的重要组成部分。诸如Four.meme之类的平台为开发人员和社区提供了创建和启动这些令牌的工具和基础架构。

However, the rapid pace of development and the often experimental nature of memecoins can also introduce security risks. Platforms like Four.Meme must remain vigilant in order to protect their users from malicious actors.

但是，发展的迅速速度和经常的成熟性质也可以引入安全风险。诸如Four.meme之类的平台必须保持警惕，以保护其用户免受恶意演员的侵害。

The Sandwich Attack: A Malicious Tactic

三明治攻击：恶意战术

The exploit that targeted Four.Meme was identified as a sandwich attack, a market manipulation tactic that exploits the mechanics of decentralized exchanges (DEXs). In essence, a malicious actor places buy and sell orders around a victim’s transaction, effectively “sandwiching” it.

针对四分之一的漏洞被确定为三明治攻击，这是一种利用分散交易所（DEX）机制的市场操纵策略。从本质上讲，恶意演员认为围绕受害者的交易买卖订单，实际上将其“夹住”。

As explained by ExVul, the attacker used the FlashBot to perform the sandwich attack. The attacker would sell a large amount of tokens to decrease the price, followed by buying a large amount of tokens to increase the price. After sandwiching the user's trades, the attacker would quickly withdraw their liquidity, aiming to maximize profit from the price movements.

正如Exvul所解释的那样，攻击者使用Flashbot执行三明治攻击。攻击者将出售大量令牌以降低价格，然后购买大量令牌以提高价格。将用户的交易夹在夹杂物后，攻击者将迅速撤回其流动性，旨在最大程度地利用价格变动中的利润。

The attack was spotted by CertiK, which reported observing "a malicious actor attempting to exploit a new launch platform on BNB Chain with an updated sandwich attack strategy."

这次袭击是由Certik发现的，该袭击事件报道了“试图通过更新的三明治攻击策略来利用BNB链上新的发射平台的恶意演员”。

The attack exploited a vulnerability in the platform's launch function, leading to the loss of approximately $120,000 in cryptocurrency funds. Following the incident, Four.Meme quickly suspended its launch function and notified users about the scam via Telegram.

这次攻击利用了该平台的启动功能中的漏洞，导致损失约12万美元的加密货币基金。事件发生后，FOR。Meme迅速暂停其启动功能，并通过电报通知用户有关骗局的通知。

The platform's response to the incident has been swift and transparent, highlighting the importance of community feedback and cooperation in mitigating such attacks.

该平台对该事件的反应是迅速而透明的，强调了社区反馈与合作在缓解此类攻击方面的重要性。

DeFi platforms, despite offering numerous advantages, are still susceptible to new types of attacks as the ecosystem evolves. In this case, the attackers were able to capitalize on a known vulnerability and execute their exploit successfully.

尽管提供了许多优势，但Defi平台仍然容易受到生态系统发展的新型攻击的影响。在这种情况下，攻击者能够利用已知漏洞并成功执行其剥削。

The crypto community can contribute by reporting any suspicious activity and remaining vigilant in identifying and reporting security vulnerabilities. Active participation in security audits, bug bounty programs, and community forums can help to improve the overall security of the DeFi ecosystem.

加密社区可以通过举报任何可疑活动并保持警惕，以识别和报告安全漏洞来做出贡献。积极参与安全审核，漏洞赏金计划和社区论坛可以帮助改善Defi生态系统的整体安全性。
