Contributed to the google/osv-scalibr repository by developing and integrating advanced detection features for sensitive data, including a core SSN detector and expanded IBAN coverage. Leveraged Go and regular expressions to enhance detection accuracy, reduce false positives, and enforce high-sensitivity data handling policies. Refactored code to improve maintainability, updated documentation, and introduced engine-based test scaffolding using veles.NewDetectionEngine and bytes.Reader for reliable IO in tests. Addressed bugs related to property references, findings handling, and naming consistency, while broadening test coverage for real-world scenarios. The work resulted in more robust, maintainable, and compliant backend detection capabilities for sensitive information.

Jun 1, 2026June 2026 monthly summary for google/osv-scalibr: Key features delivered: - SSN Detector Core integrated with existing regex support, updated detector list, and Fix SSN MaxLen; cherry-picked related SingleRegex changes to align behavior with SSN detector PR. This work delivers tighter SSN detection with clearer detector topology. - SimpleRegex Detector Enhancements: export detector fields and adjust FromMatch to return a veles.Secret, enabling nil and more flexible reporting; cherry-picked SimpleRegex changes to improve interoperability with the new detection flow. - IBAN detector added and SSN Format Reference integrated to broaden detector coverage; IBAN formatting improvements included for readability and efficiency. - Detection Engine integration in tests: set up detection engine via veles.NewDetectionEngine in tests and switch IO paths to bytes.Reader for reliability. - Extensive test updates: SSN acceptance tests, keyword-based likelihood adjustments, and IBAN-related test expansions to improve coverage. Major bugs fixed: - Fix property references after internal rename to ensure correct bindings. - Findings handling improvements: copy buffers rather than reusing, ensure FromMatch returns the correct type, and fix finding name. - False positives reduction by enforcing word boundaries on long high-entropy strings. - Maintenance and cleanup across the batch (cleanup commits) to stabilize history. Overall impact and accomplishments: - Expanded PHI detector coverage (SSN, IBAN) with higher accuracy and safer handling of high-sensitivity data. - Improved testability and CI readiness through engine-based tests and IO refactors; better reliability for real-world scans. - Clear business value: more robust data-sensitivity compliant detections, reduced false positives, and maintainable, well-documented code paths. Technologies/skills demonstrated: - Go, veles detection engine integration, and regex-based detection. - High-sensitivity data handling (SensitivityLevel High) for SSN/IBAN, and context-aware likelihood with KeywordsRe. - Refactoring, cherry-picking across PRs, test scaffolding, and documentation quality improvements.
