February 2025 was focused on delivering core connector capabilities, strengthening data quality, and improving onboarding and security posture across the OpenCTI-Platform/connectors suite. Key features delivered include the Proofpoint ET Reputation data ingestion connector, which ingests IPs and domains into STIX 2.1 observables (plus optional indicators and relationships) with minimum-score filtering and built-in deployment/debug capabilities; and the Hatching Triage Sandbox extension to analyze URLs in addition to artifacts, improving playbook compatibility and the mapping of relationships between observables and extracted indicators. A third initiative modernized connector scaffolding and configuration by updating templates/docs, adding an automated scaffold script, renaming config_variables.py to config_loader.py, and introducing TLP support with refined STIX bundle creation that includes author and markings.\n\nMajor reliability and security improvements were implemented across multiple connectors: GroupIB Docker image security hardening (removing the sensitive .env from the image), data correctness fixes (valid_from handling and relationship directions), resolution of unhashable author IDs and type errors, and renaming of safebrowsing to google-safebrowsing with corrected docker-compose image tags. CI efficiency was improved via Dockerfile optimizations for the Bambenek connector to minimize image size. These changes collectively improved threat intel ingestion quality, SOC observability, deployment reliability, and developer onboarding velocity.
