短短一夜之间，NPM 软件生态遭遇重创。黑客通过伪装成官方通知的钓鱼邮件，成功入侵知名开发者账户，对至少 18 个高频下载的核心软件包动了手脚，并植入恶意代码。这些包的周下载量合计超过 20 亿次，而据外媒 BleepingComputer 报道，实际数字甚至高达 26 亿次，影响范围几乎覆盖整个 NPM 主流生态。

这一事件最早由网络安全机构 Aikido 披露，其还对此次供应链攻击进行了深度分析，引发了开发者和用户的广泛担忧。

18 个主流 npm 软件包遭入侵

根据 Aikido 公布的时间线显示，9 月 8 日 13:16（UTC）左右，其情报系统发现一批推送到 npm 的软件包存在可疑行为，疑似被植入恶意代码。

受影响的软件包共有 18 个，而且几乎都是下载量巨大的核心依赖，包括：

• backslash（每周下载量 26 万）

• chalk-template（每周下载量 390 万）

• supports-hyperlinks（每周下载量 1920 万）

• has-ansi（每周下载量 1210 万）

• simple-swizzle（每周下载量 2626 万）

• color-string（每周下载量 2748 万）

• error-ex（每周下载量 4717 万）

• color-name（每周下载量 1.917 亿）

• is-arrayish（每周下载量 7380 万）

• slice-ansi（每周下载量 5980 万）

• color-convert（每周下载量 1.935 亿）

• wrap-ansi（每周下载量 1.9799 亿）

• ansi-regex（每周下载量 2.4364 亿）

• supports-color（每周下载量 2.871 亿）

• strip-ansi（每周下载量 2.6117 亿）

• chalk（每周下载量 2.9999 亿）

• debug（每周下载量 3.576 亿）

• ansi-styles（每周下载量 3.7141 亿）

篡改网页上显示的恶意代码

进一步来看，Aikido 发现，黑客在这些包新发布的版本中植入了一段恶意代码。例如在 is-arrayish 中，就出现了这样的情况。

从中可以看到 index.js 文件已被修改，并且包含混淆的代码：

经过一定程度的反混淆处理后，安全研究人员发现其中仍然包含一段相当复杂的代码。

这类恶意软件本质上是一个基于浏览器的拦截器，会在网站客户端执行，能够同时劫持网络流量和应用程序接口。

它会注入到 fetch、XMLHttpRequest 以及常见的钱包接口中，在请求和响应过程中静默篡改数据。

也就是说，任何敏感标识符（如支付地址或授权对象）都可能在用户看到或签署之前，就被替换为攻击者控制的目标。为了让篡改不易被察觉，它还会利用字符串匹配逻辑，将原始目标替换为“长得很像”的地址。

其危险之处在于，它能在多个层面同时发挥作用：篡改网页上显示的内容、干扰 API 调用、操纵应用程序认为用户正在签署的交易。即便界面显示一切正常，底层的交易依然可能在后台被重定向。

恶意代码的工作机制（分步解析）

基于此，安全研究人员深度分解了恶意代码的工作机制，具体如下：

1. 注入浏览器环境

• 挂钩核心函数，如 fetch、XMLHttpRequest 以及钱包相关 API（window.ethereum、Solana 等）。

• 确保能够同时拦截网络流量与钱包活动。
  

2. 监视敏感数据

• 扫描网络响应与交易负载，寻找看似钱包地址或转账信息的内容。

• 能识别多种加密货币格式，包括 Ethereum、Bitcoin、Solana、Tron、Litecoin 和 Bitcoin Cash。

3. 篡改目标地址

• 将合法的转账目标替换为攻击者控制的地址。

• 通过字符串匹配使用“伪装地址”，使替换不易被发现。

4. 劫持签名前的交易

• 修改 Ethereum 和 Solana 交易参数（如收款方、授权、额度）。

• 即使界面看似正常，用户签署的交易也会把资金导向攻击者账户。

5. 保持隐蔽性

• 检测到加密钱包时，会避免在界面上直接显示可疑替换，以降低怀疑。

• 在后台持续运行静默挂钩，捕获并篡改真实交易。

维护者发声：误点了看似来自官方的邮件，结果中招了

这起事件的开源库维护者表示，他是因遭遇钓鱼攻击而被入侵的。

攻击者使用了一封伪装成来自 support [at] npmjs [dot] help 的邮件实施钓鱼，看起来就是官方发的邮件：

进一步调查发现，该域名是在 2025 年 9 月 5 日注册的，也就是在发起攻击的三天前。

随即，每周下载量 3.576 亿次的 Debug（https://github.com/debug-js/debug）软件包的维护者 Josh Aikido 也于 15:15 在社交媒体上承认自己的库遭到了入侵，并开始清理受影响的软件包。

Josh Aikido 同时透露，钓鱼邮件正是由 support [at] npmjs [dot] help 发送的。

随着事件的发酵，Josh Aikido 也在 HackerNews 向众多用户致歉，“抱歉大家，非常尴尬。”

攻击者再度出手

随着时间的推移，网络安全机构 Aikido 发现在 16:58 时，其系统又检测到另一个软件包遭到疑似同一批攻击者的入侵：

proto-tinker-wc@0.1.87

其中的 dist/cjs/proto-tinker.cjs.entry.js 文件被植入了恶意代码。

入侵指标（IoCs）

钓鱼域名：npmjs.help

受影响的软件包版本：

虽然这属于供应链攻击，但来自 Privy 的首席安全工程师 Andrew MacPherson 解析道，一个应用程序要受到影响需要满足特定条件，这大大降低了事件的实际影响范围。具体包括：

• 在东部时间大约上午 9 点到 11 点 30 分之间进行全新安装，而这段时间正是软件包被篡改的窗口期

• 在此期间创建了 package-lock.json

• 受影响的软件包存在于直接依赖或间接依赖中

这次供应链攻击延续了过去几个月针对多个知名 JavaScript 库开发者的一系列类似攻击。

例如，今年 7 月，攻击者入侵了每周下载量超过 3000 万次的 eslint-config-prettier，而今年 3 月，又有 10 个广泛使用的 npm 库被劫持并植入信息窃取功能。钓鱼攻击和被注入的恶意软件都显示出，网络浏览器已经成为一个巨大的攻击面，容易被用于窃取凭证、篡改流量以及突破网络防护。
