In this clip, Warren describes a real-world scenario where a website had its .git folder left publicly accessible. Anyone who knew where to look could download the full source code, including hard-coded credentials and sensitive internal network details. Warren highlights how this oversight let him clone and host the entire website, creating a serious security breach.
By simply navigating to slash .git, it was possible to see everything stored in the repository. This mistake underscores the importance of properly securing application directories and ensuring that no critical files are accessible from the public internet. If you leave your .git folder exposed, you risk handing attackers the keys to your kingdom.
