猿人学第五题（js逆向）

分析网络请求，我们可以确定，该部分加密是加密的cookie

所以我们开始寻找加密的位置。

直接搜索，当你试一下搜索的内容的时候，你是无法直接搜索到的，因为这段加密他的键名是通过字符累加产生的，这边我是直接一步一步分析js代码，最后定位到了这个位置

打上断点，开始hook

hook代码

Object.defineProperty(document,'cookie',{
    set:function (params) {
        debugger;
        return params;
    }
})

成功hook到

我们可以找到第一个加密参数m

继续调试，我们发现每放一次断点，这个m的值就会刷新一次，我们继续放。观察内容变化的规律，以及发生的位置。

一直调试我们可以发现m的加密出现的规律是先出现四次，然后加载另一个cookie ，中间穿插第五次加密

那么我们可以先拷贝下来m的生成函数。

可以发现这个参数是一个时间戳，那么我们可以知道前四次加密的参数也是时间戳。

继续释放找到另一个cookie的位置。找到之后向上跟栈

我们可以发现这个cookie是通过字符串拼接进行赋值的，这也就解释了为什么我们无法搜索到这个位置

可以确定加密的就是这个函数

直接搜索这个函数，我们可以发现这是一个window对象，所以采用hook的方法找到他的这个属性对应的生成位置

hook代码

Object.defineProperty(window,'_$ss',{
    set:function (params) {
        debugger;
        return params;
    }
})

要是没成功多试一下

找到加密的位置

直接复制代码，将里面的一些参数进行替换。可以看出来这个过程是AES加密，但是我们呢并不确定是否存在修改，可以搜做一下这个_$Tk

var _$Ww = _$Tk['enc']['Utf8']['parse'](_0x4e96b4['_$pr']['toString']())
var _0x29dd83 = _$Tk['AES']['encrypt'](_$Ww, _0x4e96b4[_0xc77418('0x6', 'OCbs')], {
        'mode': _$Tk['mode']['ECB'],
        'padding': _$Tk['pad']['Pkcs7']
    })
cookie1 = _0x29dd83['toString']();

可以确定是直接导的库。

那么AES加密是需要密钥和明文数据的，开始找一下这个内容

可以确定这两个内容就是需要的明文和密钥了，我们直接拷贝试一下对不对

可以确定这个加密没有修改，并且明文和密文都已经找到具体的位置

那么我们现在来找一下明文的位置

直接搜索，向上找第一个就是

我们来分析一下，这个位置上存在m的加密，我们记得m的加密总共有五次，先进行四次后面又进行了一次，前四次的位置都是再上方哪里，那么最后一次就是在这个位置。

m前四次的位置。我们调试一下进行验证

可以直接验证这个位置的加密就是最后一次m的值，而这个_0x4e96b4['_$pr']我们在前面已经说过了这个是一个明文数据，我们直接断到这个位置看一下，现在可以知道就是这个明文的数据跟m的加密逻辑是一样的。

我们先断到机密的位置记录一下这个明文数据，发现是五个内容

我们可以看出，在m前四级加密的位置上，这个数组将前四次加密的m存了下来，等到真正得到m的数据的位置，又放入了一次。

、

这五个数据完美的找到了，也就是五个时间戳通过跟m相同的加密方式进行加密，最终得到这个结果。m是最后一次进行的加密。现在开始找密文数据。

这个直接搜索即可

我们是可以直接看到他是有个try-catch进行判断的，所以默认就是第一个，那么剩余的时间就是扣代码了，需要一直进行，扣取，注意，我建议大家的格式一定要规范，对变量的定义就写在最上面，然后依次进行填写代码，我就是因为这个问题导致浪费了很多时间。

我们再来分析一下携带的两个参数

我这边继续调试一下可以发现一个规律这个m的参数时间跟m最后一次的时间是一致的

那么我们现在可以明白这个m是用来验证加密参数cookie是不是正确的，也可以用来表明cookie生效时间，我们看一下m的起始值

这个mf的值生成时间是比m的时间早的大概时间是在5000毫秒，感兴趣的可以试一下，现在所有的参数已经找到了，只需要将代码补全即可，这个里面没有很多需要补环境的地方，大部分内容都是直接扣下来就行，部分内容是一个定值可以直接替换。
