This detection rule monitors for direct commits made to the master or main branch of GitHub repositories. It utilizes GitHub logs to identify events specifically targeting these key branches. Direct changes to the master branch are significant because they circumvent standard review protocols, introducing the risk of unauthorized code changes and potential security vulnerabilities. The analytic detects anomalies in commit activity that could indicate malicious intent, unauthorized access, or attempts to compromise the codebase integrity. Responding to detected events involves reviewing the provenance of the commits, the authorship, and the context in which changes were made, ensuring that no harmful codes are introduced through these direct modifications.
