解题思路
- 用pyinstxtrator解析exe
- 重点：将无后缀的5先修改后缀为pyc，然后随便找一个pyc文件补齐5.pyc的前16位十六进制数值（这道题以struct.pyc为例）
- 将.pyc反编译为.py
- 找到maze，从而找到最短路径
改后缀
下载附件，拿到一个无后缀的文件，丢入winhex里看看，发现是MZ开头的，去搜MZ开头是什么文件
MZ开头的是.EXE可执行文件
修改后缀
查壳
64位，无壳，但是该exe是被pyinstaller打包后得到的，我们需要将exe转换为py形式
python反编译
pyinstxtractor.py自行下载，在这个页面打开cmd
使用pyinstxtractor.py反编译exe文件，命令如下：
python pyinstxtractor.py 可执行文件exe的地址
在当前文件夹会多出一个文件夹
可以看到可疑的文件5，struct
这里我们需要先将文件5和struct加上后缀.pyc，因为后续需要进行.pyc反编译成.py文件（其实struct可要可不要，struct的作用就是给5.pyc补齐前面缺失的十六进制数值，将其他的正常的.pyc文件替换struct.pyc也可以，因为我发现.pyc文件的前16位数值都是一样的）
在winhex打开两个pyc文件，将struct的前16位十六进制数复制到5.pyc开头
记得保存
将5.pyc文件反编译成.py文件，网址：https://tool.lu/pyc/
down下来，得到一个python文件

return None在maze下面添加一个for循环，输出maze，会报错，把最下面的return none直接删了，这不是重点不要紧
修改之后的代码，可以直接输出maze

Mice walk in a maze: wasd to move,q to quit
flag is the shortest path's md5,example:if the shortest path is wasdsdw,the flag is md5('wasdsdw')

接下来可以自己慢慢找，也可以写脚本，我直接从佬那拉的脚本，可以直接输出迷宫的最小路径
python

使用wasd表示最短路径就是（一定不要忘了最后一个 * 还需要往下走一个才到达终点，我服，看了半天才找到这个错误）：
sssssddssddssaaaassssddwwddddssssssaawwaassssddssaassddddwwddssddwwwwwwwwaawwddwwwwaaaawwddwwwwddssssddwwwwddddwwddddssaassaassddddssddssaassssssddsssssss
根据python里面的内容，flag是用wasd表示的最短路径的md5值
取32位小写，69193150b15c87d39252d974bc323217
