Developers generally like to share their code, and many of them do so by open sourcing it on GitHub, a social code hosting and collaboration service. Many companies also use GitHub as a convenient place to host both private and public code repositories by creating GitHub organizations where employees can be joined.

Sometimes employees might publish things that should not be publicly available. Things that contain sensitive information or things that could even lead to direct compromise of a system. This can happen by accident or because the employee does not know the sensitivity of the information.

Gitrob is a command line tool that can help organizations and security professionals find such sensitive information. The tool will iterate over all public organization and member repositories and match filenames against a range of patterns for files that typically contain sensitive or dangerous information.
