易语言？
拿到程序，发现是易语言写的，还有点奇怪，直接x64dbg调试先看，跑起来发现易语言只是套了个外壳：
执行py脚本

Py脚本
从temp目录找到check.py和对应的CPython2.7解释器，不用想解释器肯定是改过的，先定位到程序版本：
图片描述
程序版本是2.7.18，从官网下载源码编译，https://www.python.org/ftp/python/2.7.18/Python-2.7.18.tgz

Python执行原理
温顾一遍解释器原理也是有必要的，首先定位到几个关键点：

处理Opcode
目前还没找到很简单的方法，目前用了两种方式：
1、编写测试代码生成，用两个解释器生成pyc，再用dis模块反汇编对比，这里可写个脚本提高下效率，这种方式能找到到绝大部分。
2、对于方式1不好生成的指令，通过IDA对比PyEval_EvalFrameEx函数，手动识别特征代码（字符串、关系调用等）

重新编译python
替换了源码中的Include/opcode.h和Lib/opcode.py，最终生成python可以执行check.py，开始以为作者在解释器上做了大量工作，事实上并没有。

名称混淆：
图片描述

指令switch平坦 + 花指令：
switch：每一条指令通过XOR跳往switch判断下一条指令
花指令：这里的opcode当NOP处理
图片描述

字符串加密（这里是后面Trace发现的）,通过base64、zlib、xor等解密

因为指令switch那块比较固定，静态还原代码也不是很难，考虑效率问题，最后还是找到了不错的动态跟踪的工具：
x-python仓库：https://github.com/rocky/x-python
做了如下改动：

最后执行python_d.exe xpy.py -v check.pyc，几分钟后到了raw_input输入，看了下之前代码如下：

执行效果还不错，看到了具体代码，以后有空再改造下把栈的信息拿出来，方便分析。

直接逆推不出来，注意到m、n、j、k的初始值和最后运算方式一致，因此可以把mnjk推导出来，至于k的值（最多是0-15），因此跑个16次计算，再把结果校验，最后得到KCTF的flag：
