Arthur Khasanov enhanced subdomain enumeration workflows in open-source security tools by focusing on Netlas API integration and backend reliability. For digininja/theHarvester, he refactored the Netlas subdomain search to pre-count available subdomains, optimize data fetching, and migrate API calls to a more reliable download endpoint, improving both efficiency and accuracy for security investigations. In projectdiscovery/subfinder, Arthur addressed query accuracy by excluding main domains and correcting query formats, reducing false positives in subdomain results. His work, primarily in Go and Python, demonstrated careful attention to API integration, backend development, and network security, delivering targeted improvements with clear, maintainable code changes.

February 2025 monthly summary for projectdiscovery/subfinder: Delivered a critical Netlas Subdomain Query Accuracy fix that excludes the main domain from Netlas results and corrects the query format, significantly improving subdomain retrieval accuracy and reducing false positives. This work enhances data quality for customers relying on Netlas-enabled enumeration and strengthens overall product reliability in the subfinder pipeline. The fix is implemented in netlas.go and committed as 'FIX: query for downloading subdomains in netlas.go' (commit 6cbfed905eea02b3b09bd3848e49ea26fc4c026e). Technologies demonstrated include Go, Netlas integration, bugfix discipline, and careful query validation.
