一、页面分析
打开开发者模式，好家伙直接不让调试，那就让他失效
右键点击行数地方，然后点Add conditional breapoint
输入false，点击运行就可以调试了
然后看下接口参数，只有m是加密的，那么我们就去找他的加密方法！
二、加密参数破解
1.加密函数入口
直接下XHR调试，最后在主页面的这些JS比较可疑，我们直接扣下来看看
主要代码如下：
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'](/=+$/, '');
var A = '';
for (var C = 0x0, b, W, l = 0x0; W = T['charAt'](l++); ~W && (b = C % 0x4 ? b * 0x40 + W : W, C++ % 0x4) ? A += String['fromCharCode'](0xff & b >> (-0x2 * C & 0x6)) : 0x0) {
W = m['indexOf'](W)
}
return A
};
var t = function (w, m) {
var T = [], A = 0x0, C, b = '', W = '';
w = Y(w);
for (var R = 0x0, v = w['length']; R < v; R++) {
W += '%' + ('00' + w['charCodeAt'](R)['toString'](0x10))['slice'](-0x2)
}
w = decodeURIComponent(W);
var l;
for (l = 0x0; l < 0x100; l++) {
T[l] = l
}
for (l = 0x0; l < 0x100; l++) {
A = (A + T[l] + m['charCodeAt'](l % m['length'])) % 0x100, C = T[l], T[l] = T[A], T[A] = C
}
l = 0x0, A = 0x0;
for (var L = 0x0; L < w['length']; L++) {
l = (l + 0x1) % 0x100, A = (A + T[l]) % 0x100, C = T[l], T[l] = T[A], T[A] = C, b += String['fromCharCode'](w['charCodeAt'](L) ^ T[(T[l] + T[A]) % 0x100])
}
return b
};
J['luAabU'] = t, J['qlVPZg'] = {
}, J['bSSGte'] = !![]
}
var H = J['qlVPZg'][o];
return H === undefined ? (J['TUDBIJ'] === undefined && (J['TUDBIJ'] = !![]), N = J['luAabU'](N, E), J['qlVPZg'][o] = N) : N = H, N
};
eval(atob(window['b'])[J('0x0', ']dQW')](J('0x1', 'GTu!'), '\x27' + mw + '\x27'));
return ''
}
然后加密位置估计就是这条语句
eval(atob(window['b'])[J('0x0', ']dQW')](J('0x1', 'GTu!'), '\x27' + mw + '\x27'));
接下来分析下里面的参数atob(window['b'])、J('0x0', ']dQW')、J('0x1', 'GTu!')、mw
我们下断点后直接在控制台输出atob(window['b'])，好家伙加密函数直接出来
J('0x0', ']dQW')、J('0x1', 'GTu!')这两个参数可以通过页面源码的J函数解决
J('0x0', ']dQW') = ‘replace’
J('0x1', 'GTu!') = ‘mwqqppz’
var U = ['W5r5W6VdIHZcT8kU', 'WQ8CWRaxWQirAW=='];
var J = function (o, E) {
o = o - 0x0;
var N = U[o];
if (J['bSSGte'] === undefined) {
var Y = function (w) {
var m = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789+/=',
T = String(w)['replace'](/=+$/, '');
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
};
然后继续看下页面源码就知道mw参数就是一个时间戳
2.破解加密函数
之后我们整理下就可以得到参数m的加密方式
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"
}
function core_md5(p, k) {
p[k >> 5] |= 128 << ((k) % 32);
p[(((k + 64) >>> 9) << 4) + 14] = k;
