DNS cache poisoning is a serious threat to today’s Internet. We develop a formal model of the semantics of DNS caches, including the bailiwick rule and trust-level logic, and use it to systematically investigate different types of cache poisoning and to generate templates for attack payloads. We explain the impact of the attacks on DNS resolvers such as BIND, MaraDNS, and Unbound and their implications for several defenses against DNS cache poisoning.
