[Python知识库]猿人学第二题手撕OB混淆给你看(Step1-开篇)

基于AST 手撕OB混淆

猿人学题目2：

猿人学第二题难点有二,一个是抓包,二个是反混淆.

因为网页会自动刷新,在浏览器上看不到设置cookie的那个包,

需要使用fiddller之类的抓包软件,就能很清楚的看到页面被请求了两次,

第一次返回的是一个JS文件,

第二次在请求头的cookie中加入了 m 值,才返回了HTML页面

很显然,m值就是第一次请求返回的JS文件执行而来.

这个JS 是一个混淆之后的文件,而且在2021/10月份的时候对混淆方式进行了更新升级,

现有的工具(猿人学自己的解OB工具, de4js 在线解混淆)均无法直接解开这个JS文件

网上帖子几乎均已失效(因为他们都是用工具直接解的混淆)

环境配置

python：我是用的是3.10版本，并需要设置环境变量
PyCharm：集成环境的编辑器，2021.2版本
nodejs：16.14.0版本，并需要设置环境变量
node三方库：esprima 和 escodegen，分别是将js代码转换为AST和将AST转换为js代码
python三方库：execjs用于在python中调用js代码，需要使用pip3 install PyExecJS安装

已知问题及其解决方法

execjs模块可能会出现编码问题，如果报GBK编码错误,可以顺着报错信息点进去,

将构造函数里面的 encoding=None 改为 encoding=“utf-8” ,保存即可.

就猿人学第二题的JS而言,在触发其报错的地方可能会发现一个彩蛋!

文件准备

一. 编写两个工具文件

JsToJson.js 用来将JS文件转为json

// JsToJson.js
// js 转 json 
const fs = require('fs');
const esprima = require('esprima')
const escodegen = require('escodegen')

const input_text = process.argv[2];
const output_text = process.argv[3];

const data = fs.readFileSync(input_text);
const ast = esprima.parseScript(data.toString());
const ast_to_json = JSON.stringify(ast);
fs.writeFileSync(output_text, ast_to_json);

JsonToJs.js 将json转为js

// JsonToJs.js
// json 转 js
const fs = require('fs');
const esprima = require('esprima')
const escodegen = require('escodegen')

const input_text = process.argv[2];
const output_text = process.argv[3];

const data = fs.readFileSync(input_text);
const ast = JSON.parse(data.toString());
const code = escodegen.generate(ast, {
    format: {
        compact: true,
        escapeless: true
    }
});
fs.writeFileSync(output_text, code);

二. 获取混淆JS文件

直接用python请求目标网址,不带请求头,就可以拿到混淆过后的JS文件

# my_spider.py
import copy
import json
import os
import sys

import requests
import config
import execjs


def get_02_ob_js():
    res = requests.get(f'{config.host}/match/2')
    with open('./02_ob.js', 'wb') as f:
        f.write(res.content[8:-9])
    os.system('node JsToJson 02_ob.js 02_ob.json')

    # 总文件分为6个部分,将前三个与后三个部分拆开
    with open('./02_ob.json', 'r', encoding='utf8') as f:
        node = json.loads(f.read())
    left_3_node = {
        'type': 'Program',
        'body': node['body'][:3],
        'sourceType': 'script'
    }
    right_3_node = {
        'type': 'Program',
        'body': node['body'][3:],
        'sourceType': 'script'
    }
    with open('02_ob_left_3.json', 'w', encoding='utf8') as f1, open('02_ob_right_3.json', 'w', encoding='utf8') as f2:
        f1.write(json.dumps(left_3_node))
        f2.write(json.dumps(right_3_node))

    os.system('node JsonToJs 02_ob_left_3.json 02_ob_left_3.js')
    os.system('node JsonToJs 02_ob_right_3.json 02_ob_right_3.js')

将JS文件,放进 AST 在线结构解析中可以发现,整个JS文件分为6个部分

序号	作用
1	大数组
2	自执行还原大数组
3	解密函数组
4	原函数体
5	检测函数
6	定时启动检测函数

大致上来看是一种ob混淆的变形，通过分析如下图

在函数调用还原前，字符串被提取了出来，所以相对于ob混淆多了一个步骤

字符串与数字回填
函数调用还原
对象调用还原
分支流程判断
控制流平坦化

每一步的详细过程,将在之后的文章中写出,因为篇幅很长,准备做成一个系列专题,每步一篇文章

将上面5步最后剩余的代码经过手动删减(剔除影响调试的代码,暴露接口)之后,

得到以下可使用python 直接调用的代码:

调用方式:

# my_spider.py
def get_m():
    with open('02_ob_sort_reload.js', 'r', encoding='utf8') as f:
        data = f.read()
    value = execjs.eval(data)
    print(value)
    return value

在这里插入图片描述
