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.
An example of an IDN homograph attack; the Latin letters "e" and "a" are replaced with the Cyrillic letters "е" and "а".The internationalized domain name (IDN) homoglyph attack (often written as homograph attack) is a method used by malicious parties to deceive computer users about what remote system they are communicating with, by exploiting the fact that many different characters look ...
DNS hijacking, DNS poisoning, or DNS redirection is the practice of subverting the resolution of Domain Name System (DNS) queries. [1] 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 does not comply with internet standards.
This type of geolocation spoofing is also referred to as geo-piracy, since the user is illicitly accessing copyrighted materials via geolocation spoofing technology. Another example of geolocation spoofing occurred when an online poker player in California used geolocation spoofing techniques to play online poker in New Jersey, in contravention ...
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.
Routers can pass bad DNS information in two ways: misconfiguration of existing settings or wholesale rewrite of embedded software (aka firmware). Many routers allow the administrator to specify a particular, trusted DNS in place of the one suggested by an upstream node (e.g., the ISP). An attacker could specify a DNS server under his control ...
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.
Domain Name System (DNS) resolution is the process of translating a human-readable domain name (for example, en.wikipedia.org) into an IP address that computers can use. Every ISP runs a DNS server to allow their customers to translate domain names into IP addresses that computers understand and use.
