阻止HomeCoin攻击:行业首个成功阻止案例

March 10, 2022

自 BlockSec 于 2021 年首次亮相以来,我们一直坚持认为,仅靠代码审计无法解决 Web3 安全问题。因此,我们一直在投入资源探索 Web3 安全的新范式。为此,我们创建了 Phalcon,这是世界上第一个加密货币黑客攻击阻止系统。

在 Phalcon 推出之前,该系统已在内部运行了 2 年,成功阻止了 20 多次黑客攻击,挽救了价值超过 2000 万美元的资产,其中包括为 Saddle Finance 挽救的 380 万美元,为 Platypus 挽救的 240 万美元,为 ParaSpace 挽救的 500 万美元,等等。

在本系列文章中,我们将展示我们系统 Phalcon 的代表性成功案例。今天,让我们来了解一下 Web3 中的一个改变游戏规则的故事:行业首次成功防御黑客攻击。

我们是如何阻止 HomeCoin 攻击的

秉持着保护 Web3 生态系统需要的不仅仅是安全审计的信念,我们在 2022 年初开发了主动威胁预防系统(即 Phalcon)的原型。我们拥抱未知,不确定系统是否能真正运行并产生结果,体验了忐忑与兴奋交织的心情。

2022 年 3 月 5 日下午 4:35:19 (UTC),我们的系统检测到攻击者 (0xC711374BaC07Df9bB9dbAC596451517cEcBf0F0f) 发起的待处理攻击。随后,我们系统的另一个组件自动触发了构建反击交易,该交易被迅速发送(0xf3bd801f5a75ec8177af654374f2901b5ad928abcc0a99432fb5a20981e7bbd1),并成功阻止了攻击(原始失败的攻击交易:0xc161973ed0e43db78763aa178be311733d4ffb77948d824ed00443803d22739c)。

由于受害者合约仍然存在漏洞(典型的重入漏洞),受威胁的资产被转移到一个安全且公开的专用救援账户。最终,此事件以圆满结局告终。我们联系了项目方(即 HomeCoin),并将救援的代币(0x31bff8989e9d627331435df9fed118f988b50bd1ab3b6056600ce86ccf0275ea)返还给他们的部署者账户(0x67368f4c89dda2a82d12d3a703c32c35ff343bf6)。

尽管与许多事件中的损失相比,救援的代币数量并不显著,但这标志着首次有公开记录的自动阻止进行中攻击的尝试。我们相信这是保护区块链生态系统的正确方向。这个切实的例子表明,这是可行的,代表着“人类的一小步,却是人类的一大步”。

尽管仍然存在许多挑战,但这代表着即将到来的黎明和未来,我们正致力于在不久的将来实现它。

Tether Freezes $6.76M USDT Linked to Iran's IRGC & Houthi Forces: Why On-Chain Compliance is Now a Geopolitical Battlefield

Looking ahead, targeted freezing events like this $6.76M USDT action will only become more common. On-chain data analysis is improving. Stablecoin issuers are also working closely with regulators. As a result, hidden illicit financial networks will be exposed.

Weekly Web3 Security Incident Roundup | Mar 2 – Mar 8, 2026

During the week of March 2 to March 8, 2026, seven blockchain security incidents were reported with total losses of ~$3.25M. The incidents occurred across Base, BNB Chain, and Ethereum, exposing critical vulnerabilities in smart contract business logic, token deflationary mechanics, and asset price manipulation. The primary causes included a double-minting logic flaw during full token deposits that allowed an attacker to exponentially inflate their balances through repeated burn-and-mint cycles, a price manipulation vulnerability in an AMM-based lending market where artificially inflated vault shares created divergent price anchors to incorrectly force healthy positions into liquidation, and a flawed access control implementation relying on trivially spoofed contract interfaces that enabled attackers to bypass authorization to batch-mint and dump arbitrary tokens.

Weekly Web3 Security Incident Roundup | Feb 23 – Mar 1, 2026

During the week of February 23 to March 1, 2026, seven blockchain security incidents were reported with total losses of ~$13M. The incidents affected multiple protocols, exposing critical weaknesses in oracle design/configuration, cryptographic verification, and core business logic. The primary drivers included oracle manipulation/misconfiguration that led to the largest loss at YieldBloxDAO (~$10M), a crypto-proof verification flaw that enabled the FOOMCASH (~$2.26M) exploit, and additional token design and logic errors impacting Ploutos, LAXO, STO, HedgePay, and an unknown contract, underscoring the need for rigorous audits and continuous monitoring across all protocol layers.
