文章搭配视频地址：挖洞遇到验证码那些事
正文
输入手机号码与账号密码登录的接口都有滑块。区别在于账号密码登录的时候有个加盐密码。流程比手机号码的接口复杂一下，为了省时间。此文章便是根据手机号码的接口去写的，毕竟咱的目的是过滑块嘛。
1
发包逻辑分析
每次刷新验证码，都会发四个数据包下来。第一个数据包用于请求图片。图片链接的拼接就是urlParams加上imgs的值。
2
第三个数据包是背景图
3
第四个数据包是缺口图片
4
正确拼接验证码，短信验证码发送成功
5
captcha_signature在刷新验证码发下来的数据包里面的sign参数。
captcha_phrase和captcha_ticket在getTicket接口从服务器返回回来的，captcha_phrase是缺口，如果缺口对齐失败的话captcha_ticket是获取不到的。所以得先把getTicket接口的参数补齐拿到ticket。
6
getTicket的前五个参数直接从getPreHandle接口返回的urlParams获取。
7
8
phrase直接用搜索大法就能搜到关键位置
phrase: (x) + ";" + inity + ";" + opt.width + ";" + opt.height
x是缺口识别的x轴,opt.width和opt.height是固定的值
inity也是直接在js文件一搜就能拿到他的关键代码。data.data.inity在getPreHandle接口里面的inity。这段代码就是取那个inity相除相乘再拼接到phrase里头
inity = (data.data.inity / 195 * opt.height);
x直接就是缺口识别然后减去15(因为图片实际大小跟他在网页上面的大小不一样)，懒得缩小了。因为通过训练相同的图片跟缺口其x就相差15，直接减更方便(懒人做法)
图片缺口识别代码：
def detect_captcha_gap(bg, tp):
'''
bg: 背景图片
tp: 缺口图片
return:空缺距背景图左边的距离
''' # 读取背景图片和缺口图片
bg_img = cv2.imread(bg) # 背景图片
tp_img = cv2.imread(tp) # 缺口图片
# 识别图片边缘
bg_edge = cv2.Canny(bg_img, 100, 200)
tp_edge = cv2.Canny(tp_img, 100, 200)
# 转换图片格式
bg_pic = cv2.cvtColor(bg_edge, cv2.COLOR_GRAY2RGB)
tp_pic = cv2.cvtColor(tp_edge, cv2.COLOR_GRAY2RGB)
# cv2.imwrite("bg_style.png",bg_pic) # 保存背景轮廓提取
# cv2.imwrite("slide_style.png",tp_pic) # 保存滑块背景提取
# 缺口匹配
res = cv2.matchTemplate(bg_pic, tp_pic, cv2.TM_CCOEFF_NORMED)
min_val, max_val, min_loc, max_loc = cv2.minMaxLoc(res) # 寻找最优匹配
th, tw = tp_pic.shape[:2]
tl = max_loc # 左上角点的坐标
# 返回缺口的左上角X坐标
br = (tl[0] + tw, tl[1] + th) # 右下角点的坐标
cv2.rectangle(bg_img, tl, br, (0, 0, 255), 2) # 绘制矩形
cv2.imwrite("result_new.png", bg_img) # 保存在本地
# 返回缺口的左上角X坐标
return tl[0]
x = detect_captcha_gap("bg.jpg","tp.jpg")-15
mobile加密就是一个rsa加密，没有任何混淆跟难点。
验证码校验接口还有个hexin-v参数
9
hexin-v硬扣
校验验证码的数据包里面有个加密的header参数hexin-v,他跟cookie的v是一模一样的。有两种方法可以找到关键加密位置，第一种是headers hook,第二种是cookie hook。
10
cookie hook代码：
(function () {
'use strict';
var cookieTemp = "";
Object.defineProperty(document, 'cookie', {
set: function (val) {
console.log('Hook捕获到cookie设置->', val);
if (val.indexOf('v') != -1) {
debugger;
}
cookieTemp = val;
return val;
},
get: function () {
return cookieTemp;
}
});
})();
在控制台输入hook的代码
11
断点断了下来。回溯堆栈找到关键代码加密的地方
12
w函数便是设置cookie的函数，r就是v加密生成返回的值。那么qn.update()就是v生成的函数了。把断点下到qn.update()那一行然后刷新。由于这个网站的js文件是动态生成的，所以需要重新进入新的js文件在qn.update()那一行重新下个断点刷新。
13
断点断下之后进入qn.update()看看里面写了啥
14
进入到qn.update()函数内部可以看出他返回了另外一个函数的返回值。
15
把断点断到R函数这一行进入到R函数内部。
16
R函数往E对象里面压入一堆值。找找E在哪里生成的。
17
E对象是在b函数里面被赋值的，但因作用域的原因，他并不是在这里声明的，E声明的地方还得往上面去找。
18
在945行找到E声明的地方，同时也发现了这一段大的函数是一个自执行的函数。
19
开始扣代码，就只扣需要的代码，R()是v加密后的值，R函数里面有E对象，E对象是在b函数里面被实例化的。b函数也扣下来，b函数里面调用了C函数。C函数也一并扣下来。因为E对象是全局作用域，其声明的代码在几个函数的外面。
var o = r[40], i = r[37], u = e[26], c = e[121], s = parseInt(Kn(n[80], e[122], t[135]), t[67]), f = n[94], v = r[59], l = e[74], p = n[53], d = parseInt(t[29], t[62]), h = parseInt(n[68], n[134]), g = n[135], m = parseInt(e[123], n[51]), w = parseInt(n[136], e[58]), I = parseInt(e[124], t[136]), _ = parseInt(e[125], e[79]), y = parseInt(n[137], n[134]), A = parseInt(e[126], t[67]), E;
function C() {
var r = Wn.getCookie(On) || $n.get(Pn);
if (r && r[t[59]] == parseInt(n[138], t[62])) {
var e = Qn.decode(r);
if (e && (E.decodeBuffer(e),
E[o] != n[29]))
return
}
E[o] = Gn.random()
}
function b() {
var t = e[31]
, a = parseInt(e[127], e[26])
, o = r[52]
, u = parseInt(e[128], e[26]);
E = new Un([u, u, u, u, t, t, t, o, a, a, a, a, a, a, a, u, a, t]),
E[i] = Gn.serverTimeNow(),
C(),
E[_] = Dn,
E[A] = xn,
E[y] = n[29],
E[c] = Gn.strhash(navigator.userAgent),
E[w] = Yn.getBrowserFeature(),
E[s] = Yn.getPlatform(),
E[f] = Yn.getBrowserIndex(),
E[v] = Yn.getPluginNum()
}
function R() {
var n = Y;
E[y]++,
E[i] = Gn.serverTimeNow(),
E[u] = Gn.timeNow(),
E[_] = Dn,
E[l] = Jn.getMouseMove(),
n = q,
E[p] = Jn.getMouseClick(),
E[d] = Jn.getMouseWhell(),
E[h] = Jn.getKeyDown(),
E[g] = Jn.getClickPos().x,
E[m] = Jn.getClickPos().y;
var t = E.toBuffer();
return Qn.encode(t)
}
console.log(R())
代码运行报错，r未定义。那么e,t,n是否也是未定义。在浏览器运行一下看看是什么呢
20
在控制台打印r,e,t,n。发现他们都是大数组。直接扣下来就行了
21

运行报window，document未定义。在开头定义一下为空对象
22
var window ={}
var document={}
运行报Kn未定义
23
把断点下到报错代码那一行，进去Kn函数内部
24
function Kn() {
var r = arguments[t[31]];
if (!r)
return t[33];
for (var a = e[32], o = n[25], i = n[29]; i < r.length; i++) {
var u = r.charCodeAt(i)
, c = u ^ o;
o = u,
a += n[27].fromCharCode(c)
}
return a
}
运行报错Y未定义。
25
浏览器查看Y是字符串“1”，直接在代码中写固定就行
26
报这个错的原因是因为没有调用b函数，在R函数的开头调用运行一下b函数。
27
对象实例化Un函数是未定义的。去浏览器扣。
28
浏览器扣下来的Un函数
var Un = function() {
var a = r[44]
, o = r[45];
function i(a) {
this[e[53]] = a;
for (var o = r[40], i = a[t[59]]; o < i; o++)
this[o] = n[29]
}
return i[r[46]][r[47]] = function() {
for (var o = t[60], i = this[n[47]], u = [], c = -n[30], s = n[29], f = i[Kn(r[48], t[61])]; s < f; s++)
for (var v = this[s], l = i[s], p = c += l; u[p] = v & parseInt(a + o, t[62]),
--l != e[27]; )
--p,
v >>= t[62];
return u
}
,
i[A + E][Xn(e[54], r[49], x)] = function(a) {
for (var i = t[63], u = this[T + o + i], c = t[35], s = n[29], f = u[Xn(n[48], r[50])]; s < f; s++) {
var v = u[s]
, l = r[40];
do {
l = (l << r[51]) + a[c++]
} while (--v > n[29]);this[s] = l >>> e[27]
}
}
,
i
}()
运行报Xn未定义，分析代码的作用是把函数赋给对象，那么i后面跟着的肯定是字符串，把函数赋给某某对象原型链下面的某个属性。
29
替换即可。
30
运行报Gn未定义，直接进入Gn.serverTimeNow()函数内部查看写了什么。
31
浏览器扣下来的代码，看看这段代码有什么作用。
function cn() {
var n = (s,
u,
new v[84]);
return typeof TOKEN_SERVER_TIME == x + T + C ? I[27] : (time = parseInt(TOKEN_SERVER_TIME),
time)
}
cn函数有一个三元表达式，TOKEN_SERVER_TIME是数值，x + T + C是"undefined"，TOKEN_SERVER_TIME == x + T + C 是false
所以执行(time = parseInt(TOKEN_SERVER_TIME),time)
这段函数的整体意思是将TOKEN_SERVER_TIME取整赋值给time，再把time值返回。
32
E[i] = Gn.serverTimeNow()直接改写成E[i] = parseInt(TOKEN_SERVER_TIME)
运行代码报错TOKEN_SERVER_TIME未定义，在浏览器搜索TOKEN_SERVER_TIME。
33
在第一行就可以看到TOKEN_SERVER_TIME。直接扣下来
34
运行报错Wn未定义。这段C函数代码要是直接去扣就入坑了，先看看这个C函数有什么作用。
35
第一行代码就是取cookie名为v的值，如果没取到cookie的v值就去取headers的"hexin-v"值。
var r = Wn.getCookie(On) || $n.get(Pn);
36
一般情况下都不是第一次运行，那么他就会取得到前面cookie的v值。那么下面的if判断就会成立，就会执行。但是我们总不可能每次运行代码都去取他前面的cookie，那实在是太复杂了。假设，我是说假设。假设我每一次进去这个网站都是第一次，都取不到cookie的v值和headers的hexin-v。那么这段代码又是有什么样的作用呢。
37
cookie的v和headers的hexin-v都取不到值的话那么if里面的就是null。就直接执行后面的代码
38
最后C函数的代码就是直接改写成E[o] = Gn.random()
运行报错,直接扣Gn.random()
39
function rn() {
var n = sn;
return n = G,
Math.random() * parseInt("11111111111111111111111111111111", 2) >>> 0
}
C函数可以值改写成
E[o] =Math.random() * parseInt("11111111111111111111111111111111", 2) >>> 0
Dn报错
40
Dn是数值0
41
xn未定义
42
xn是数值3
43
报了Gn的错。分析这段代码就是把浏览器指纹ua传进了strhash函数。可以直接取最后的值写固定。
44
E[c] = 自己浏览器头strhash后的值
后面的报错都是这几个值未定义。
45
getBrowserFeature—>获得浏览器特性
getPlatform—>获取浏览器平台
getBrowserIndex—>获取当前网页所在浏览器的索引
getPluginNum—>获取当前网页或浏览器环境中已安装或可用的插件数量。
至于改写的话直接取最后的值就行了
b函数都改完之后到R函数报错了。Gn.serverTimeNow()在b函数就已经扣过了
Gn.serverTimeNow()—>parseInt(TOKEN_SERVER_TIME)
46
Gn.timeNow()未定义
47
进入Gn.timeNow()函数内部是个on函数
48
on函数的作用就是取当前时间戳除以1000再无符号右移0位
改写后的代码
E[u] = Date.now()/ 1000
后面的代码都是未定义的
49
Dn是数值0，n是字符串"DOMMous"
50
getMouseMove—>获取鼠标当前的横坐标和纵坐标
getMouseClick—>获取鼠标点击时的横坐标和纵坐标，以及所点击的按钮
getMouseWhell—>获取滚轮事件的信息
getKeyDown—>获取按键事件的信息
getClickPos—>获取鼠标点击的坐标，然后进行相应的操作，比如记录点击位置或者根据点击位置执行特定的逻辑。
直接取最后运行完的值
运行Qn.encode未定义
51
进入函数内部Qn对象总共有4个方法，直接把Qn对象补齐.
52
var Qn;

var o = e[55]

_.push(y >> parseInt(Vn(f[53], Tn), d[61]), y >> c[51] & parseInt(Xn(X, p[62]), g[51]), y & parseInt(u[64], h[52]))
}
return _
}
function f(n, t, a, i, u) {
for (var c = n[o + C]; t < c; )
a[i++] = n[t++] ^ u & parseInt(r[54], e[61]),

}
for (var v = e[64], l = {}, p = n[29]; p < parseInt(Vn(t[65], r[56]), r[51]); p++)
l[v.charAt(p)] = p;
function d(n) {

}

g(a)
}
function g(a) {

var s = a[o++] << parseInt(b + R, r[51]) | a[o++] << r[51] | a[o++];
c.push(v.charAt(s >> parseInt(e[65], n[53])), v.charAt(s >> parseInt(n[54], t[62]) & parseInt(Xn(e[66], r[58], S), e[61])), v.charAt(s >> r[59] & parseInt(B + i, t[46])), v.charAt(s & parseInt(n[55], r[55])))
}
return c.join(Vn(r[26], n[56]))
}
function m(n) {
var t, a, o;
t = a = o = r;
var i, u, v;
i = u = v = e;
var l = s(n);
if (l[u[27]] != c)
return error = i[67],
void 0;
var p = l[t[37]]
, h = [];
return f(l, +a[60], h, +i[27], p),
d(h) == p ? h : void 0
}
a[Vn(r[61])] = g,
a[Hn($n, n[57], t[68])] = s,
a[k + u] = h,
a[O + S] = m
}(Qn || (Qn = {}));
运行报错
53
在浏览器打印o+C是字符串"length"，直接替换
54
55
在浏览器打印Vn(r[61])是字符串"100"，直接替换
56
后面几个都是未定义的，在浏览器找到对应的值替换
57
58
a["base64Encode"] = g,
a["base64Decode"] = s,
a["encode"] = h,
a["decode"] = m
直接拿运行之后的结果进行替换
59
Xn(q, t[66], In)—>"ff"
60
61
G—>"w"
62
63
Xn(e[66], r[58], S)—>"3f"
64
65
B + i—>"3f"
66
67
Vn(r[26], n[56])—>""
68
代码再次执行，值便出来了。
69
带上值去请求一遍。手机验证码发送成功
70
hexin-v(js-dom补环境
在网上看到一堆文章都又说直接用js-dom包补document和window两个环境。
直接把整个js文件复制下来
71
定义一个全局变量接受v的值,方便后面导出。
运行代码报window未定义
72
导包
const jsdom = require('jsdom')
const {JSDOM} = jsdom;
const {window} = new JSDOM(``);
运行代码报document未定义
73
const document = window.document
运行代码报navigator未定义
74
const navigator = window.navigator
75
打印值出来了，报错不用管。直接用py调用。也是成功的！
76
