Episode 15 — Extract domain intelligence that drives confident pivots
Domain names and their associated infrastructure are often the most visible and easily trackable components of an adversary's offensive operation. This episode focuses on extracting "domain intelligence" from DNS records, mail exchanger (MX) settings, and IP resolutions to uncover the broader scope of a threat actor's network. We explain how to use this data to drive "confident pivots," moving from a single malicious domain to identifying the registrant's email, other domains hosted on the same IP, or even the adversary's preferred hosting provider. In a real-world investigation, this intelligence allows you to "get ahead" of an attack by proactively blocking new domains before they are even used in a campaign. For the GCTI exam, you must be proficient in using tools like WHOIS, passive DNS, and sub-domain enumeration to map out an attacker's staging ground. Mastering domain intelligence is key to disrupting the "delivery" and "command-and-control" phases of the kill chain.
