GitHub CC Checker

The GitHub CC Checker analyzes repositories to identify exposed credit card numbers, tokens, and other sensitive patterns within code, history, and commit messages. It is designed for security engineers, DevOps teams, and compliance auditors who need rapid visibility into leakage risks before code merges or public disclosure.
Conceptually, the tool uses pattern-based detection with regular expressions tailored to common card formats and secret templates. An optional historical scan reviews changes across commits to uncover data that was introduced or retained over time. When matches are found, a structured report lists file path, line number, and a contextual snippet.
Core value includes automated risk assessment, reproducible results, and CI-friendly integration. The tool returns a prioritized set of hits, an overall risk score, remediation recommendations (rotate credentials, purge history, redact data), and export options (JSON/CSV) for ticketing and SIEM workflows.
Common use cases include pre-merge checks for pull requests, regular audits of public repositories, onboarding new teams to security hygiene, and post-incident analysis. The tool differentiates itself by focused CC pattern detection, care for false positives, and easy integration with existing development pipelines.
