If you create a new repository in an organization, the setting is inherited from what is configured in the organization settings. Note that references to the malicious commits could still be found in the repository events and these commits may still be accessible directly via their SHA-1 hashes in cached views on GitHub. How can I recognize one? To automate the detection of unprotected secrets in all commits of a repository, tools like TruffleHog3 and Gitleaks4 can come in handy.
