PROFILE

Sergei Yakima

Contributed to the metron-labs/content repository by developing and securing backend integrations over a two-month period. Built an Abuse.ch Hunting API integration using Python, enabling analysts to retrieve and analyze false positives removed from blocklists, which improved threat intelligence workflows and incident response accuracy. Applied API integration and unit testing skills to support robust HTTP calls and command handling. In a separate effort, addressed a path traversal vulnerability in the WildFire integration by implementing secure file upload and deletion logic, enhancing data integrity and compliance. Demonstrated a methodical approach to backend development, vulnerability remediation, and cross-team collaboration throughout both projects.
