Threat Hunting with DNS

Domain Name System (DNS) is one of the fundamental building blocks of the internet. DNS translates domain names (e.g., www.example.com) into IP addresses when users want to access a specific website on the internet. This translation allows users to easily access websites and contributes to the smooth functioning of internet traffic. However, this critical role of DNS can be abused by cybercriminals.
