DNS translates human-readable domain names into IP addresses through a hierarchical, largely unauthenticated lookup process, which makes it both indispensable and a prime target for abuse. Because DNS traffic is trusted by default and rarely blocked by firewalls, attackers exploit it for cache poisoning that redirects victims to malicious servers, and for tunnelling that smuggles command-and-control traffic disguised as ordinary lookups. Understanding how resolution actually works is what lets a defender recognize when DNS is being used for something other than its intended purpose.

💪 Think of it like fitness: injuries follow a predictable chain — poor warm-up, then form breakdown, then compensation, then the actual tear — and a good physio catalogs where each patient's chain can be interrupted early, rather than only treating the tear afterward. MITRE ATT&CK is the sports-medicine literature of intrusions: a public catalog of every observed breakdown pattern, organized by the stage it serves — how attackers get in, how they escalate, how they extract. Coaches worldwide describe an athlete's risk in that shared vocabulary. This reveals ATT&CK's real value: intrusions become a sequence you can interrupt at stage two, not a disaster you discover at stage five.
