猿人学攻防大赛题一

猿人学攻防大赛题一

距离猿人学攻防大赛已经好久了，而我是最近才开始js逆向，但是现在学习也不晚，正年轻嘛，哈哈哈哈哈哈。

话不多说，我要开始bb了，嘿嘿。

分析：

当我们F12会看到如下界面：

那我们就要去debugger，应该这样操作，在上图红圈里鼠标右键，然后点击下图的1，然后点击下图的2，就可以去debugger了。
然后呢，再点击Network,看XHR里最大的文件就好了，然后在Priview可以看到下面图片的样子，value对应的就是价格。
我们看看它的headers，如下图：
这个参数m是通过js加密的，看’丨’的左边是不是2感觉很熟悉，很像我们的老熟人呀，那我们可以猜测一波是老熟人时间戳。

我们用ctrl+shift+f全局搜索m一下，但是搜索到了好多，这么找不是办法呀，那我又试了一下上面蓝色那个竖杠杠，可以找到仅仅一个，开心，哈哈哈哈。

我们点击看一下,如下图：
我们再在上面黄色代码那个页面ctrl+f一下进行搜索那个竖杠杠，结果如下图
点一下左下角的括号，可以进行代码美化，我们可以把与headrs中的加密参数m相关的代码取出，

request = function () {
    
    
    var timestamp = Date.parse(new Date());
    var m = oo0O0(timestamp.toString()) + window.f;
    var list = {
    
    
    "page": window.page,
     "m": m + '丨' + timestamp / 1000
    }

可以看出timestamp是先被定义，即

var timestamp = Date.parse(new Date());

我们你找到Date.parse(new Date())这个，其实就是上面10位的时间戳乘以1000，我是怎么知道的呢？我们可以看一下Console，把Date.parse(new Date())复制过去就好了。

然后找一下m,先看这个：

var m = oo0O0(timestamp.toString()) + window.f;

我们先找一下oo0O0这个，里面的timestamp.toString()就是上面10位的时间戳乘以1000，我们把oo0O0复制到Console中寻找一下

我们点击oo0O0下面的，也就得到下面代码

function oo0O0(mw) {
    
    
    window.b = '';
    for (var i = 0, len = window.a.length; i < len; i++) {
    
    
        console.log(window.a[i]);
        window.b += String[document.e + document.g](window.a[i][document.f + document.h]() - i - window.c)
    }
    var U = ['W5r5W6VdIHZcT8kU', 'WQ8CWRaxWQirAW=='];
    var J = function (o, E) {
    
    
        o = o - 0x0;
        var N = U[o];
        if (J['bSSGte'] === undefined) {
    
    
            var Y = function (w) {
    
    
                var m = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789+/=',
                    T = String(w)['replace'](/=+$/, '');
                var A = '';
                for (var C = 0x0, b, W, l = 0x0; W = T['charAt'](l++); ~W && (b = C % 0x4 ? b * 0x40 + W : W, C++ % 0x4) ? A += String['fromCharCode'](0xff & b >> (-0x2 * C & 0x6)) : 0x0) {
    
    
                    W = m['indexOf'](W)
                }
                return A
            };
            var t = function (w, m) {
    
    
                var T = [], A = 0x0, C, b = '', W = '';
                w = Y(w);
                for (var R = 0x0, v = w['length']; R < v; R++) {
    
    
                    W += '%' + ('00' + w['charCodeAt'](R)['toString'](0x10))['slice'](-0x2)
                }
                w = decodeURIComponent(W);
                var l;
                for (l = 0x0; l < 0x100; l++) {
    
    
                    T[l] = l
                }
                for (l = 0x0; l < 0x100; l++) {
    
    
                    A = (A + T[l] + m['charCodeAt'](l % m['length'])) % 0x100, C = T[l], T[l] = T[A], T[A] = C
                }
                l = 0x0, A = 0x0;
                for (var L = 0x0; L < w['length']; L++) {
    
    
                    l = (l + 0x1) % 0x100, A = (A + T[l]) % 0x100, C = T[l], T[l] = T[A], T[A] = C, b += String['fromCharCode'](w['charCodeAt'](L) ^ T[(T[l] + T[A]) % 0x100])
                }
                return b
            };
            J['luAabU'] = t, J['qlVPZg'] = {
    
    }, J['bSSGte'] = !![]
        }
        var H = J['qlVPZg'][o];
        return H === undefined ? (J['TUDBIJ'] === undefined && (J['TUDBIJ'] = !![]), N = J['luAabU'](N, E), J['qlVPZg'][o] = N) : N = H, N
    };
    eval(atob(window['b'])[J('0x0', ']dQW')](J('0x1', 'GTu!'), '\x27' + mw + '\x27'));
    return ''
}

可以看到return '',即oo0O0(timestamp.toString())=' ',那var m = ''+window.f;
然后呢，找一下window.f

可以看到上图，没有，那我们放一放，我查阅了一些资料，发现，eval这个里面有时有文章。
我们看上面代码，有eval(atob(window['b'])[J('0x0', ']dQW')](J('0x1', 'GTu!'), '\x27' + mw + '\x27'));其中atob() 方法用于解码使用 base-64 编码的字符串。我们把atob(window['b'])复制到Console，输出的是代码，我们把它在本地美化了一下：

var hexcase = 0;
var b64pad = "";
var chrsz = 16;

function hex_md5(a) {
    
    
    return binl2hex(core_md5(str2binl(a), a.length * chrsz))
}

function b64_md5(a) {
    
    
    return binl2b64(core_md5(str2binl(a), a.length * chrsz))
}

function str_md5(a) {
    
    
    return binl2str(core_md5(str2binl(a), a.length * chrsz))
}

function hex_hmac_md5(a, b) {
    
    
    return binl2hex(core_hmac_md5(a, b))
}

function b64_hmac_md5(a, b) {
    
    
    return binl2b64(core_hmac_md5(a, b))
}

function str_hmac_md5(a, b) {
    
    
    return binl2str(core_hmac_md5(a, b))
}

function md5_vm_test() {
    
    
    return hex_md5("abc") == "900150983cd24fb0d6963f7d28e17f72"
}

            } else {
    
    
                f += c.charAt((e >> 6 * (3 - a)) & 63)
            }
        }
    }
    return f
};window.f = hex_md5(mwqqppz)

我们在这个最后可以看到window.f = hex_md5(mwqqppz)，wiindow.f在这里藏着，不要看着上面代码多，其实有许多在加密里没用到，这也对应这道题的题目。

我们继续找eval(atob(window['b'])[J('0x0', ']dQW')](J('0x1', 'GTu!'), '\x27' + mw + '\x27'));中的参数，atob(window['b']我们已经找到，那我们找J('0x0', ']dQW')，我们把J('0x0', ']dQW')复制到Console到中

我们可以看到J没有被定义，其实J在它们上面（oo0O0函数中），我们把关于J的复制到console，然后会提示
u没有被定义，我们再把带有u,J的复制到console中，enter一下，然后再J('0x0', ']dQW')，

可以看到J('0x0', ']dQW')对应字符"replace"，我们在找一下J('0x1', 'GTu!')，可以看到

J('0x0', ']dQW')对应字符"mwqqppz",接下来解一下这个'\x27' + mw + '\x27'，mw是传入的，即function oo0O0(mw)，我们再回顾开始代码，

request = function () {
    
    
    var timestamp = Date.parse(new Date());
    var m = oo0O0(timestamp.toString()) + window.f;
    var list = {
    
    
    "page": window.page,
     "m": m + '丨' + timestamp / 1000
    }

可以看到，mw其实就是timestamp.toString()，也就是10位时间戳乘以1000，那我们在console试一下，可以看到

\x27对应的是一个符号 ’ ，好了，解密差不多了，我们试一下，其实这里用到的是找到window.f = hex_md5(mwqqppz)所在的代码里面，在这里我们要改一下，就是在最后改一下

var chrsz = 16;

    var timestamp=Date.parse(new Date());
    m = hex_md5(timestamp.toString()) + '丨' + timestamp / 1000;
    return m  //返回加密m
}

其实;window.f = hex_md5(mwqqppz)被我用定义的m函数代替，另外与下面这个

request = function () {
    
    
    var timestamp = Date.parse(new Date());
    var m = oo0O0(timestamp.toString()) + window.f;
    var list = {
    
    
    "page": window.page,
    "m": m + '丨' + timestamp / 1000
    }

结合在一起了。

接下来是python代码，我直接展示了，

import execjs
import requests
from time import sleep
from random import randint

def m():
#这里我把我的js文件叫做‘一’了（也就是上面被我改的代码，
# 里面有我定义m函数那个），这里用的相对路径。
    path = '一.js'
    with open(path,'r',encoding='utf8') as f:
        js=f.read()
    js = execjs.compile(js)
    m=js.call('m')
    return m
