目标：分析 Cookie acw_sc__v2 的生成逻辑
阿里系cookie 参数acw_sc__v2 是一个风控的基础算法，大多网站触发风控的话会出现阿里滑块acw_sc__v3。这个网站算是比较简单的一个网站，有个vv购物网站只要打开了开发者工具请求接口就会触发阿里滑块风控，就不拿那个例子举例了，因为其算法都是一样通用的。
正文
发包逻辑分析
打开fidder抓个包，刷新页面抓到了两个数据包。第一个数据包有个服务器返回的cookie，而且他的内容是一段ob混淆的js代码。
1
2
第二个数据包有两个cookie参数，其内容返回正常
3
4
第二个数据包的cookie参数acw_sc__v2总不可能无故产生的，猜测其生成的地方在第一个数据包里面，在第一个数据包里面搜索acw_sc__v2，搜到了。果然有！
5
acw_sc__v2生成逻辑
把cookie参数acw_sc__v2删掉，打开控制台刷新。
6
有个反调试无限debugger，有很多方法可以过掉这个无限debugger，我这次使用的是把关键函数置空的方法。堆栈回溯到关键调用的地方。
7
在315和316行打断点，然后刷新。注意是刷新，不是跳到下一个断点。
8
当断点断在315行的时候执行_0x4db1c()函数置空的方法
_0x4db1c = ()=>{}
把断点从315行跳到316行，执行定时器置空的方法。
setInterval= ()=>{}
无限debugger过了之后，用hook的方法在生成cookie的地方断下来，我们之前分析数据包的时候就已经找到了设置cookie的地方，但是并不确定是不是在那里生成的cookie。
hook cookie代码：
cookie_cache = document.cookie;
Object.defineProperty(document, "cookie", {
get: function () {
console.log(cookie_cache);
// 在获取document.cookie时，执行你想要的操作
return cookie_cache; // 返回原始的cookie值
},
set: function(value) {
// 在设置document.cookie时，执行你想要的操作
if(value.includes('acw_sc__v2')){
debugger;
}
}
});
cookie被hook到了
9
回溯堆栈看看cookie生成的代码在哪里，reload函数是设置cookie的函数，但是并不是生成cookie的函数。cookie x 是由上面传下来的，还得回溯上去寻找生成x的函数。
10
异步跟栈到了一个定时器函数。2秒后执行vm里面的reload(arg2)，reload不就是我们设置cookie的函数嘛，那么arg2有可能就是实参！
11
12
在控制台打印了arg2，还真是cookie的值
13
把arg2生成的代码扣下来，
arg2 = _0x23a392[_0x55f3('0x1b', '\x7a\x35\x4f\x26')](_0x5e8b26);
14
把_0x23a392的定义代码扣下来
var _0x23a392 = arg1[_0x55f3('0x19', '\x50\x67\x35\x34')]();
运行报错arg1未定义。
15
搜索arg1在页面上就有，这个arg1经测试是可变的，需要每次从新的js代码用正则提取出来。
16
报_0x55f3未定义，在浏览器执行_0x55f3('0x19', '\x50\x67\x35\x34')是字符串"unsbox"
17
18
去浏览器把函数扣下来吗，但是代码是混淆过的，运行报了很多错误。手动解混淆

外传—>浅谈_0x55f3解混淆函数算法还原
仅仅只是我在调试的时候的一些坑，这些都是外面文章没有的点。比如硬扣_0x55f3，_0x55f3我个人猜测是一个解混淆的一个函数。
在扣_0x5e8b26我就进入到_0x55f3去扣，复现一下步骤吧
把断点下到172那行，重新刷新页面过掉debugger,进入函数内部
28
把代码扣下来执行，报了个不知道是什么的错。好像是溢出
29
把_0x55f3解混淆之后可以看到他有几个分支，在浏览器看看她走的哪个分支。
30
31
前四个分支都是false，于是只走了_0x48181e = _0x55f3["data"][_0x4c97f0];前面的分支都可以删掉了
在浏览器打印_0x55f3["data"]是个大数组，而_0x5e8b26传进去的_0x4c97f0是3，而_0x55f3["data"][3]刚刚好就是"3000176000856006061501533003690027800375"
32
33
那么再看看其他的，像上面的"unsbox"跟"hexXor"和"length"都在数组里面，最简单的方法就是取最后生成完的大数组，然后把坐标丢数组里面去取就完事了。
34
以上就是初步分析(在_0x5e8b26赋值的地方进入函数前四个分支都是false的情况)，还有第二种情况。
在204这行下断点。重新进入页面去掉无限debugger然后进入函数内部
35
也跟之前一样看看进入哪个分支
36
这一次进入的是第四个分支，把前三个分支删了
37
第四个分支的第一个分支也删了
38
解完混淆的代码只剩下这些了
39
在浏览器一直单步执行，准备进入_0x55f3["rc4"]函数内部
40
_0x55f3["rc4"]函数就是_0x232678函数，把这个函数扣下来
41
再把_0x4818从浏览器扣下来然后把无关紧要的_0x55f3["data"][_0x4c97f0] = _0x48181e删掉，因为我们直接调用就没必要把他存起来了。
然后解码函数_0x55f3就可以调用了。因特殊原因，解密函数就不能分享给大家了，大家按照我的思路去走绝对可以还原出解密函数的。
