Worked on the OpenCTI-Platform/connectors repository to address a critical bug affecting CrowdStrike integration reliability and performance. Focused on Python-based API integration, the work introduced robust error handling for scenarios where the CrowdStrike API token lacked the necessary indicator scope permission. By implementing defensive programming techniques and caching import results, the solution prevented repeated API calls that would otherwise trigger permission errors, thereby reducing operational risk and API load. This approach improved report import efficiency and stabilized data ingestion for CrowdStrike data. Emphasis on unit testing ensured the changes were reliable, reflecting a methodical approach to error handling and system optimization.
