DNS spoofing, also referred to as DNS cache poisoning, is a form of computer security hacking in which corrupt Domain Name System data is introduced into the DNS resolver 's cache, causing the name server to return an incorrect result record, e.g. an IP address. This results in traffic being diverted to any computer that the attacker chooses.
DNS hijacking, DNS poisoning, or DNS redirection is the practice of subverting the resolution of Domain Name System (DNS) queries. This can be achieved by malware that overrides a computer's TCP/IP configuration to point at a rogue DNS server under the control of an attacker, or through modifying the behaviour of a trusted DNS server so that it ...
DNS amplification attacks involves an attacker sending a DNS name lookup request to one or more public DNS servers, spoofing the source IP address of the targeted victim. The attacker tries to request as much information as possible, thus amplifying the DNS response that is sent to the targeted victim.
Spoofing attack. In the context of information security, and especially network security, a spoofing attack is a situation in which a person or program successfully identifies as another by falsifying data, to gain an illegitimate advantage. [1]
Pharming [a] is a cyberattack intended to redirect a website 's traffic to another, fake site by installing a malicious program on the victim's computer in order to gain access to it. [citation needed] Pharming can be conducted either by changing the hosts file on a victim's computer or by exploitation of a vulnerability in DNS server software.
DNS rebinding is a method of manipulating resolution of domain names that is commonly used as a form of computer attack. In this attack, a malicious web page causes visitors to run a client-side script that attacks machines elsewhere on the network. In theory, the same-origin policy prevents this from happening: client-side scripts are only ...
DNS is the layer at which botnets control drones. In 2006, OpenDNS began offering a free service to prevent users from entering website spoofing sites. Essentially, OpenDNS has gathered a large database from various anti-phishing and anti-botnet organizations as well as its own data to compile a list of known website spoofing offenders.
The Domain Name System Security Extensions ( DNSSEC) are a suite of extension specifications by the Internet Engineering Task Force (IETF) for securing data exchanged in the Domain Name System ( DNS) in Internet Protocol ( IP) networks. The protocol provides cryptographic authentication of data, authenticated denial of existence, and data ...
