Git (pronounced “git”) is a version control system that helps track the history of changes in files. Git is used by programmers to collaborate on projects. A repository is all files under version control, along with their change history and other service information. You can create a Git repository either by selecting any folder on your computer, or by cloning an existing repository, for example, from your employer. There are different ways of storing and using a repository: local, centralized and distributed version control systems are distinguished. GitHub is the most popular site for storing and working with git repositories. Also, GitHub is the largest platform for hosting open source projects. No registration or account payment is required to view and download public repositories. In a sense, GitHub is also a social network for developers. Registered users can publish content and manage their own repositories, contribute to other people’s repositories, lead discussions, view code changes, comment on them, and follow the updates of friends.
GitHub is often used in recruitment – an active account and high-quality code can greatly help in finding a job. Therefore, it is especially important to have an account to show your code to colleagues and how it evolves over time. Now there are many other online services integrated with Git. Alternatives to GitHub are, for example, GitLab and BitBucket. Both sites have a smaller audience, but have their own functionality and advantages, for example, BitBucket is more suitable for small closed-source projects.
With the right searches, various snippets of code can be found in Github repositories that contain credentials to connect to the company’s infrastructure and are used by developers and QA engineers. Methods and techniques for searching information in public repositories for secrets* can help us uncover hidden and interesting applications before their immediate security analysis begins.
Secret refers to private keys, account details, and other confidential information.
Here it is worth understanding one nuance, we can look for secrets in the official repository of the organization, and we can in unofficial repositories of its employees or contractors. The more sources we have, the more likely we are to find the data we need. The process of finding secrets on Github or other repositories can be observed on a great flowchart. We can use various tools to search for information in repositories and to automate such processes.
