在上一篇文章：<https://forum.butian.net/share/1206> 中做代码审计的时候，提到过 phpjm 混淆的解密还原，后面有一些小伙伴私信问具体过程，本篇就展开说说。

我们就从手动解混淆、debug解混淆、写脚本解混淆三个方向去说

0x01 手动解混淆
==========

首先将代码中的`eval`替换成`echo`，并且执行 php 文件  
![image-20220407181350795.png](https://shs3.b.qianxin.com/attack_forum/2022/04/attach-ecec1f71c7022d15d99022c0996c2902416dafd3.png)

然后把执行输出的代码复制替换掉前面整个`echo`语句，即如下  
![image-20220407181655795.png](https://shs3.b.qianxin.com/attack_forum/2022/04/attach-e4e9ddae6a5af1657e2df20d3b1e363ca91f2e0a.png)

接着重复工作，继续把下面的`eval`函数替换成`echo`输出

![image-20220407181812920.png](https://shs3.b.qianxin.com/attack_forum/2022/04/attach-498d56ac2a8b5e31ffba8a4493990a62084b643c.png)

![image-20220407181831404.png](https://shs3.b.qianxin.com/attack_forum/2022/04/attach-f69c18e482e78f058ce1954ddb79e8c8983da6db.png)

接着继续执行，重复如此，最终成功还原成原来的代码

![image-20220407181905562.png](https://shs3.b.qianxin.com/attack_forum/2022/04/attach-9ea0912c085271f7e24986e81e6aef746edbca85.png)

0x02 debug解混淆
=============

这里我使用的是 vscode + Xdebug + PHP Debug(vscode插件)  
首先格式化一下代码，并且打上断点，选择单文件调试，即`Launch currently open script`  
![image-20220407182409090.png](https://shs3.b.qianxin.com/attack_forum/2022/04/attach-3a3783ca58caf9de9d7d70fba9b4652933f7d8d4.png)

然后 F5 启动调试，接着 F11 走单步调试  
![image-20220407182514950.png](https://shs3.b.qianxin.com/attack_forum/2022/04/attach-96a6904365351b8912123784303fef80b99c5478.png)

可以看到变量不断的被赋值，接着一直按 F11 单步调试，最后跟完得到还原后的代码

0x03 编写脚本
=========

这里我们看一道 bugku平台 上的题：《getshell》  
![image-20220407182858438.png](https://shs3.b.qianxin.com/attack_forum/2022/04/attach-c46d3321dbee3fdeefb5174e8a0c43c44b47bac9.png)

这题如果手解或者debug，耗时会很长，并且这题也不能无脑的一直 F11 去调试，我们可以通过前面观察样本的特征动手编写一个自动解密脚本。通过前面的手动解混淆，我们大概能清楚需要完成的工作就是把`eval`替换成`echo`之后执行，接着把执行输出的结果再替换原文件中的`eval`函数内容。

同时可以看到混淆后的特征大体为`$xxxxx{num}`的形式，我们可以通过这个特征去写一个正则`r'(\$[a-zA-Z0-9]+{[0-9]\d{0,1}})'`判断有没有解混淆完成，如果解完一层发现还存在这个特征，就继续尝试解下一层。虽然这个判断有点过于简单粗暴，但对于当前样本足以完成工作。

编写工具如下

```python

                flag = 1
            if len(Content) <= 10:

            if 'eval' in Content:
