Gitjacker downloads git repositories and extracts their contents from sites where the
.git directory has been mistakenly uploaded. It will still manage to recover a significant portion of a repository even where directory listings are disabled.
For educational/penetration testing use only.
curl -s "https://raw.githubusercontent.com/liamg/gitjacker/master/scripts/install.sh" | bash
…or grab a precompiled binary.
You will need to have
git installed to use Gitjacker.
