Worked on enhancing error handling for Microsoft Graph sign-in activity within the SpecterOps/AzureHound repository. Focused on improving reliability during authorization by expanding error coverage and implementing robust retry logic for various Graph authorization failure scenarios. Utilized Go for backend development, emphasizing API integration and comprehensive error handling to reduce sign-in failures and streamline user experience. The solution increased operational resilience by enabling smoother sign-in flows and simplifying troubleshooting. Testing was incorporated to validate the changes, ensuring that the new error handling mechanisms addressed multiple edge cases and contributed to a more stable and maintainable authentication process within the application.
