DNS Attack

Domain Name System (DNS) attack, also called DNS Spoofing or DNS cache poisoning, is aiming to redirect users to potentially malicious web servers by changing the records used to convert domain names to numerical addresses, which is used as another way for online fraudsters to install aggressive advertising software, or adware, on victims' computers and redirect people to pay-per-click Web sites. The domain name system protocol is inherently vulnerable to this style of attack due to the weakness of 16-bit transaction IDs.
