逆向题目

提取全部5页发布日热度的值，计算所有值的加和,并提交答案

开始分析

1、打开chrome浏览器后，打开开发者工具，然后在开始之前，先清空一下缓存

2、重新刷新网页，发现网站开始进入 debugger；

3、这个的反调试相对的比较简单，我们先按照最简单的方式来一下，在debugger；进行下断点

并且编辑断点为false；然后然后让代码继续走；

4、然后就直接跳转到了 网页源代码上，并且在浏览器中也正常的可以看到热度值！

5、并且在network 面板中 也可以看到 热度值的 api

6、好像没有什么可以发现的需要分析的东西，然后在点击展示页中的第二页的时候，发现cookie失效了

7、并且在点击确认弹窗的按钮后，页面进行了重载刷新，但是注意到一个细节，就是这次的刷新没有被debugger到，一切都是这么的丝滑。

那么这个点可能出现在了请求的cookie上面了！

8、发现了 在开始请求页面的时候 有过一次重载 ，

并且第一次请求页面的时候，并没有cookie值产生

返回的是一串js代码

在第二次请求相同页面的时候才传递了一个cookie值

并且这个cookie值很熟悉，对，很像第一题中的 m 值

并且可以看到一点，就是在请求热度值的数据的时候，cookie也是携带了m 值的

在加上上面的cookie失效的问题来讲，大致的可以分析出来

应该是第一次请求页面的时候，就在开始计算m 值，然后把这个m值添加到cookie中去

然后通过携带的这个m值的cookie在重新的请求一次页面 和 请求热度值获取数据

那么我们可以把 第一次请求页面的 返回js 代码进行分析一下 看看是怎么获取到m值的

又是一大坨ob的混淆，看的头痛。

那么这个如何下手嘞。。。

作为菜鸟的我想到了 两种方式


第一种就是 直接通过官网提供的OB反混淆工具 进行代码清洗

然后去 慢慢看 代码的执行流程 找到关键cookie生成m 值的地方


第二种就是 通过hook的方式 去hook cookie 的m 值 生成的时候的流程在哪里

然后开始扒需要用到的函数

OB反混淆

还是简单一点，直接把代码拖到官网的 ob反混淆工具中

最终获取了 200 多行的代码 

在里面我们可以清楚的看到 cookie m 值的生成地方

也可以看到 先生成m 值后，网页在进行重载

首先我们可以 先通过 vscode的 折叠 看一下 整体 这个js  分为多少个函数大块

折叠后  我们可以发现的是，这个js 有三个函数大块，

其中最下面的是 一个计时器setInterval

作用的函数是 $dbsm_0x20fca2

折叠开 $dbsm_0x20fca2 函数 在里面并没有看到有关于m 生成的方法

可以大致的判断，这个函数方法是检测用的，可以先屏蔽掉

计时器也是一样，屏蔽掉

然后开始看 $dbsm_0x102ce0(_0x1c3497) 这个大方法

折叠开后，可以看到这个是一个自执行的方法，

并且可以在函数的最后看到m 的生成方法

那么在这里，直接可以看出来

_0x2601b2() 方法就是时间戳的生成方法

_0x284fde  就是时间戳

_0x36c705(_0x284fde) 就是生成的时间戳加密值

然后我们吧_0x2e5d25() 这个函数改造一下

让它直接返回m值即可

在知道了_0x36c705()是加密的算法 那么继续往上找定义的地方

发现在_0x36c705里面 调用了_0x3f0df6()函数

那么继续找_0x3f0df6()定义的地方

在网上找后 又看到了一个定时器

每500毫秒执行一次_0x3f0df6()方法 

那么就直接屏蔽掉 并且可以考虑到 在这个方法里面

可能会有一些检测或者无用的垃圾代码

找到了定义_0x3f0df6()函数的地方 

看到了这串代码

      var _0x81db3b = _0x5a292f(this, function () {
        var _0x7eb303 = function () {
          var _0x47fa48 = _0x7eb303["constructor"]("return /\" + this + \"/")()["compile"]("^([^ ]+( +[^ ]+)+)+[^ ]}");
  
          return !_0x47fa48["test"](_0x81db3b);
        };
  
        return _0x7eb303();
      });
  
      _0x81db3b();


定义_0x7eb303()方法 然后 return 返回自己 明显的没有啥用，直接屏蔽掉

下面的这一串自执行代码也是一样，$dbsm_0x20fca2() 已经在之前被我们屏蔽掉

说明这一串代码也是差不多类似做检测用的，可以直接屏蔽掉

然后看这一串try 的代码  看到了global 全局的函数

判断 global 是否存在 如果不存在就执行 navigator["vendorSub"];

通过控制台输出为空 说明这个也是一个垃圾代码 直接替换为 return "";

测试代码有效性

然后我们把这个自执行的代码进行剥离
