Worked on enhancing registrar information extraction within the projectdiscovery/nuclei-templates repository, focusing on the RDAP WHOIS YAML configuration. Developed and integrated new JSON extractors to capture detailed registrar data, including IANA ID, name, organization, URL, email, and phone, thereby improving the completeness and accuracy of data retrieval. Utilized YAML for configuration management and applied data extraction techniques to streamline the process. This feature enables more comprehensive downstream analytics and supports faster triage and reporting of registrar ownership. The work demonstrates a methodical approach to API integration and configuration updates, addressing specific needs in registrar data processing workflows.
