This repository is forked from lijiejie/GitHack. I migrated the former python code to python3. The following description is the origin author's readme.

GitHack is a .git folder disclosure exploit.

It rebuild source code from .git folder while keep directory structure unchanged.

GitHack是一个.git泄露利用脚本，通过泄露的.git文件夹下的文件，重建还原工程源代码。

渗透测试人员、攻击者，可以进一步审计代码，挖掘：文件上传，SQL注射等web安全漏洞。

• 解析.git/index文件，找到工程中所有的： ( 文件名，文件sha1 )
• 去.git/objects/ 文件夹下下载对应的文件
• zlib解压文件，按原始的目录结构写入源代码

Thanks for sbp's great work, I used his .git index parser gin - a Git index file parser.
