tracking-threat-actor-infrastructure
Discovers and maps adversary-controlled infrastructure (C2 servers, phishing domains, exploit-kit hosts, bulletproof hosting) by pivoting across passive DNS, certificate transparency logs, Shodan/Censys scans, WHOIS records, and network fingerprints (JARM/JA3S). Use when tracking threat actor infrastructure, expanding a known IOC into related assets, or producing STIX-based threat intelligence during a CTI investigation.

# Tracking Threat Actor Infrastructure
## Overview
Threat actor infrastructure tracking involves monitoring and mapping adversary-controlled assets including command-and-control (C2) servers, phishing domains, exploit kit hosts, bulletproof hosting, and staging servers. This skill covers using passive DNS, certificate transparency logs, Shodan/Censys scanning, WHOIS analysis, and network fingerprinting to discover, track, and pivot across threat actor infrastructure over time.
## When to Use
- When managing security operations that require tracking threat actor infrastructure
- When improving security program maturity and operational processes
- When establishing standardized procedures for security team workflows
- When integrating threat intelligence or vulnerability data into operations
## Prerequisites
