Over a two-month period, Vanderstap contributed to projectdiscovery’s nuclei-templates and subfinder repositories, focusing on security automation and code quality. He developed detection templates in Go and YAML to identify default credentials on Schneider Electric APC devices and remote code execution vulnerabilities in QNAP Photo Station, employing HTTP-based testing, regex matching, and a self-deleting PHP dropper for accuracy and cleanup. Vanderstap also improved maintainability by refactoring code, performing YAML linting, and removing obsolete BinaryEdge sources from subfinder. His work demonstrated depth in network security, penetration testing, and vulnerability research, delivering targeted solutions that enhanced automated security analysis and repository hygiene.
