This guide demonstrates how to use Hunt.io to investigate and track malicious infrastructure. Starting with a single suspicious IP address, the process involves analyzing hosting providers, domain information, open ports, HTTP responses, and TLS certificates. The investigation reveals connections to potential cryptocurrency fraud and malware operations. By leveraging Hunt's scan data and SQL queries, a small cluster of related servers is identified, possibly linked to Latrodectus malware. The guide emphasizes the importance of persistence, pattern recognition, and correlating data from multiple intelligence sources to effectively track threat actor operations.
