前言

现在一些网站对 JavaScript 代码采取了一定的保护措施，比如变量名混淆、执行逻辑混淆、反调试、核心逻辑加密等，有的还对数据接口进行了加密，本次的案例为 RSA 加密。

RSA 是非对称加密，区分公钥和私钥，RSA 算法是目前理论和实际应用中最为成熟的和完善的公钥密码体制，其用来解决对称密码的密钥分发问题，还可以用来进行数字签名来保证信息的否定与抵赖，利用数字签名较容易发现攻击者对信息的非法篡改以保证信息的完整性。

Webpack

webpack 是 JavaScript 应用程序的模块打包器，可以把开发中的所有资源（图片、js文件、css文件等）都看成模块，通过 loader（加载器）和 plugins（插件）对资源进行处理，打包成符合生产环境部署的前端资源，所有的资源都是通过 JavaScript 渲染出来的，目前 Vue，React 等前端项目，基本上都是基于 webpack 进行工程化开发的。

一般通过 webpack 打包的 JavaScript 文件都为一整个自执行函数，以下为一类自执行函数，函数前面加上一元操作符，后面加上括号，一般自执行函数最后都是括号：

!function () {console.log("Yy_Rose")
}();

webpack 类型的基本结构

第一种类型：

// 模块为 Object 形式, 元素为函数对象
!function('参数'){'加载器'}({'模块'});

本文案例即为此种类型，function e( ) 函数体即为加载器，并包含 call( ) 方法：

!function(t) {// 加载器function e(s) {if (i[s])return i[s].exports;var n = i[s] = {exports: {},id: s,loaded: !1};return t[s].call(n.exports, n, n.exports, e),n.loaded = !0,n.exports}......
}({// 模块0: function(){},1: function(){},2: function(){},......56: function(){},
});

第二种类型：

// 模块以数组形式存储, 数组中的每个元素都是函数
!function('参数'){'加载器'}(['模块']);

将上述代码样例进行改写，即为第二种类型：

!function(t) {// 加载器function e(s) {......}......
}([// 模块function(){console.log('Yy_Rose')},......function(){console.log('Yy_Rose')},
]);

以上均做了脱敏处理，Base64 编码及解码方式：

import base64
# 编码
# result = base64.b64encode('待编码字符串'.encode('utf-8'))
# 解码
result = base64.b64decode('待解码字符串'.encode('utf-8'))
print(result)

常规 JavaScript 逆向思路

一般情况下，JavaScript 逆向分为三步：

寻找入口：逆向在大部分情况下就是找一些加密参数到底是怎么来的，关键逻辑可能写在某个关键的方法或者隐藏在某个关键的变量里，一个网站可能加载了很多 JavaScript 文件，如何从这么多的 JavaScript 文件的代码行中找到关键的位置，很重要；
调试分析：找到入口后，我们定位到某个参数可能是在某个方法中执行的了，那么里面的逻辑是怎么样的，调用了多少加密算法，经过了多少赋值变换，需要把整体思路整理清楚，以便于断点或反混淆工具等进行调试分析；
模拟执行：经过调试分析后，差不多弄清了逻辑，就需要对加密过程进行逻辑复现，以拿到最后我们想要的数据

接下来开始正式进行案例分析：

寻找入口

打开开发者人员工具进行抓包，随便输入一串账户名和密码，输入验证码后点击登录，会有如图所示的报错弹窗，在抓包到的 login3 链接的响应预览中能看到一样的报错信息，此处即为登录接口位置：

观察其请求头中的数据信息，为 GET 请求，在 Query String Parameters 中返回了一些 JSON 格式的响应数据，通过对比分析可知各关键参数的含义：

uname：明文用户名
password：加密密码
ckcode：明文验证码
_：当前时间戳

调试分析

寻找加密位置

根据上文所述，密码 password 经过加密，现对其逆向分析，这里直接全局搜索 password 关键字，可以看到有如下几个结果：

通过分析可知加密位置在 home.min.js 文件中，点击进入该 JS 文件，会发现被压缩了，为了便于查看点击左下角的 { } 进行格式化操作，接着 CTRL + F 局部搜索 password，会发现有 83 个结果，这么多不便于查找分析，由于 password 是 JSON 格式的数据，所以可以直接搜索 password: ，搜索结果减少到了 14 个，大大降低了查找的工作量：

打断点调试分析，password 加密后的值在该文件的第 178 行生成，该值由参数 o 传递：

进一步跟进参数 o 定义的位置，发现其在第 168 行定义：

var o = a.encode(t.password, s)

可以在第 168 行打下断点进行调试，也可以直接在控制台打印出各部分含义，如下图可知：

a.encode(t.password, s)：输入的密码加密后的结果
t.password：输入的明文密码
s：当前时间戳

所以参数 o 即为明文密码加当前时间戳后加密的结果，接下来进一步跟进到其 encode 加密位置，鼠标整体选中 a.encode，跟进到 home.min.js?v=IKPeng:formatted:592 中，即该文件的第 592 行：

以下即为关键的加密位置：

关键加密代码分析

如上图所示，第 588、589 行能看到两个明显的加密特征：

JSEncrypt：JavaScript 中加密模块之一，为 RSA 加密算法提供支持
setPublicKey：设置公钥

所以可以推断，返回的响应参数中 password 的值经过了 RSA 加密，以下进一步加密部分进行分析：

n.prototype.encode = function(t, e) {var i = e ? e + "|" + t : t;return encodeURIComponent(this.jsencrypt.encrypt(i))}

t：输入的明文密码
e：当前的时间戳
i：将 e 和 t 通过 | 拼接后的结果
this.jsencrypt.encrypt(i)：将 i 进行 RSA 加密
encodeURIComponent( )：对 URL 中的某个参数进行编码

模拟执行

这里通过两种方式，对加密位置模拟执行以的到加密后的 password 参数的值：

1. Node.js 引入 JSEncrypt 加密模块进行加密

// 通过 require 引入 jsencrypt 加密模块
var JSEncrypt = require('jsencrypt')function getPassword(t, e) {var jsEncrypt = new JSEncrypt();// 设置公钥jsEncrypt.setPublicKey('MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDq04c6My441Gj0UFKgrqUhAUg+kQZeUeWSPlAU9fr4HBPDldAeqzx1UR92KJHuQh/zs1HOamE2dgX9z/2oXcJaqoRIA/FXysx+z2YlJkSk8XQLcQ8EBOkp//MZrixam7lCYpNOjadQBb2Ot0U/Ky+jF2p+Ie8gSZ7/u+Wnr5grywIDAQAB');var i = e ? e + "|" + t : t;return encodeURIComponent(jsEncrypt.encrypt(i));
}// 明文密码
var password = "123456";
// 当前时间戳
var timestamp = (new Date).getTime();
console.log(getPassword(password, timestamp));

2. 改写 webpack，导出方法调用

本文一开始讲述了 webpack 模块化方法的基本样式，该 JS 文件的开头能找到加载器位置：

上文中我们找到了 password 参数的加密位置，如下图所示，该加密位置在第 3 个模块中，同时从第 591 行我们可以看到，变量 r 引用了第 4 个模块中的内容：

这里直接将模块 3 和模块 4 的内容整体扣出，再将加载器 e 作为全局变量导出调用即可：

var window = global;
var navigator = {};
!function(t) {function e(s) {if (i[s])return i[s].exports;var n = i[s] = {exports: {},id: s,loaded: !1};return t[s].call(n.exports, n, n.exports, e),n.loaded = !0,n.exports}var i = {};// 导出加载器window.code = e;
}({3: function(t, e, i) {var s;s = function(t, e, s) {function n() {"undefined" != typeof r && (this.jsencrypt = new r.JSEncrypt,this.jsencrypt.setPublicKey("-----BEGIN PUBLIC KEY-----MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDq04c6My441Gj0UFKgrqUhAUg+kQZeUeWSPlAU9fr4HBPDldAeqzx1UR92KJHuQh/zs1HOamE2dgX9z/2oXcJaqoRIA/FXysx+z2YlJkSk8XQLcQ8EBOkp//MZrixam7lCYpNOjadQBb2Ot0U/Ky+jF2p+Ie8gSZ7/u+Wnr5grywIDAQAB-----END PUBLIC KEY-----"))}var r = i(4);n.prototype.encode = function(t, e) {var i = e ? e + "|" + t : t;return encodeURIComponent(this.jsencrypt.encrypt(i))},s.exports = n}.call(e, i, e, t),!(void 0 !== s && (t.exports = s))},4: function(t, e, i) {var s, n, r, s;s = function(t, e, i) {/*!

password 参数的逆向分析到此为止，python 模拟登录部分代码在此就不予提供了，关于该网站登录中验证码的处理提供三种方式：

该网站验证码混淆不严重可以直接通过 OpenCV 库进行识别
通过验证码图片的接口 verify_image 将验证码保存到本地，然后通过 Image 库打开本地图片并通过 show() 方法展示出来，最后 input 手动输入即可
打码平台

总结

以上是对某妹游戏网登录的逆向分析，以及对 webpack 的改写调用，如有任何见解欢迎评论区或私信指正交流~
