An Automated Forensic Pipeline Using STIX 2.1 and OSINT for Neutralization of Transnational Pig Butchering and Business Email Compromise Fraud Infrastructure

This technical report presents a scalable, fully automated forensic neutralization pipeline designed to identify, enrich, and systematically dismantle transnational cyber-fraud infrastructure, specifically Pig Butchering and BEC campaigns. The framework integrates Bash-based discovery with Python-driven forensic enrichment, utilizing STIX 2.1 standardization and MITRE ATT&CK mapping. As of June 2, 2026, the pipeline has processed over 1,800 malicious domains. This research is conducted independently and emphasizes cryptographic audit logging, legal compliance (CFAA, GDPR, CCPA), and ethical targeting.
