githacker's Introduction

GitHacker

Desciption

This is a multiple threads tool to exploit the .git folder leakage vulnerability. It is able to download the target .git folder almost completely. This tool also works when the DirectoryListings feature is disabled by brute forcing common .git folder files.

With GitHacker's help, you can view the developer's commit history, branches, ..., stashes, which makes a better understanding of the target repo, even to find security vulnerabilities.

PROCLAMATION (IMPORTANT)

Several VULNERABILITIES have been reported recently, if you are using GitHacker <= 1.1.0, please update your tool as soon as possible.

The remote .git folder maybe malicious, so to prevent you from being attacked. It's highly recommended that you SHOULD run this tool under a disposable jailed environment (eg: Docker container).
