TCTF 2021 lalamblambdadambda Writeup

提取代码

运行 lalamblambdadambda.exe，提示输入 flag

监控文件读写，发现程序在 AppDataLocalTemp 下创建了 _MEI62682 文件夹

通过分析可知程序是通过 PyInstaller 打包的 Python 3.8 代码

使用 pyinstxtractor 在 Python 3.8 环境下对 lalamblambdadambda.exe 进行解包

再使用最新版本的 uncompyle6 对解包得到的 lalamblambdadambda.pyc 进行反编译

反编译结果：

try:
    flag = input('Input flag: 
')
    r = False
    if len(flag) == 22 and flag.startswith('flag{') and flag.endswith('}'):
        try:
            buf = bytes.fromhex(flag[5:21])
        except ValueError:
            buf = None

    else:
        if buf:
            tmp = [
             None] * 64
            for i in range(8):

                     lambda _: lambda __: __, lambda _: lambda __: _)[(buf[i] >> j & 1)]

逆向分析

程序通过 Python 中的 lambda 编写函数式代码对输入内容进行校验

本来想靠编译器大力优化一下，奈何调了半天编译也没通过，就只能硬看了

容易发现程序中存在若干重复出现的代码段，可以对其进行提取，再逐个分析其对应的功能
