Explanation:
Also called domain name system (DNS) poisoning or DNS cache poisoning,is the corruption of an Internet server’s domain name system table by replacing an Internet address with that of another, rogue address. When a Web user seeks the pagewith that address, the request is redirected by the rogue entry in the table to a different address. At that point, a worm, spyware, Web browser hijacking program, or other malware can be downloaded to the user’s computer from the rogue location.
