Directory Naming Service (DNS) helps resolve a site address from a common name using a list hosted on a server. When you type in a website address in human form, you need the internet protocol (IP) address. This is to send queries to the site and then download content to your browser. DNS hijacking intercepts your request and redirects you to a nefarious site or initiates a redirect download. Then, you can go to the site you originally wanted. But the malware download will have started.
