Episode 31 — Pivot from domains to infrastructure with intent
Pivoting with intent is the art of using a single technical indicator to map out an adversary's broader offensive infrastructure with surgical precision. This episode explores the methodologies for moving from a malicious domain name to identifying the underlying command-and-control (C2) servers, name servers, and hosting providers used in a campaign. We discuss the use of passive DNS (pDNS) to find historical IP resolutions and the "shared hosting" problem, where an analyst must distinguish between an attacker-controlled server and a multi-tenant environment. For the GCTI exam, you must demonstrate proficiency in using technical "anchors"—like a unique SSL certificate or a specific SSH host key—to link disparate infrastructure components to a single actor. Real-world scenarios include tracking an adversary as they rotate their IP addresses in an attempt to evade blocks, allowing you to stay one step ahead of their movements. Mastering this type of pivoting transforms a single alert into a strategic understanding of the opponent's staging area.
