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

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

迷宫最短路径

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

flag:NSSCTF{69193150b15c87d39252d974bc323217}
