A Domain Name System (DNS) Water Torture attack involves attackers sending non-existent subdomain requests to an Authoritative Name Server for a specific domain. These malicious requests consume the resources on the name server (and also on intermediate DNS resolvers) and significantly slow down the responses for legitimate requests. Ultimately, users are not able to access your web application, and then everyone has a bad day. <insert sad-face emoji here>
