For example, for testing e-mail servers, the process is summarized in the below image: Furthermore, to check for DNS vulnerabilities in web applications, the below steps can be followed: Register on a web application with an e-mail address of the following format:test@VVMMIIIIII.[your doma...
In 1993, Christoph Schuba released a paper entitled "Addressing Weaknesses in the Domain Name System Protocol". In it, he outlined several vulnerabilities, including the technique of DNS cache poisoning. In the earliest incarnation, it was possible to provide extra information in a DNS reply packet...
(link), to name a few. Caching Recursive attacks, such as Cache Poisoning attacks, or DNS Hijacking attacks all target DNS vulnerabilities as well. Just like wine, there are also a few outliers, such as DNS Tunneling attacks (link). However, most DNS attacks are either Authoritative or ...
