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. [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.
Spoofing attacks are generally harder to detect as adversaries generate counterfeit signals. These spoofed signals are challenging to recognize from legitimate signals, thus confusing ships' calculation of positioning, navigation, and timing (PNT). [12]
In computer networks, a reverse DNS lookup or reverse DNS resolution (rDNS) is the querying technique of the Domain Name System (DNS) to determine the domain name associated with an IP address – the reverse of the usual "forward" DNS lookup of an IP address from a domain name. [1]
Spoofing happens when a hacker sends an email that looks like it came from your email address. While AOL tries hard to make sure we take steps to guard against this, if you do suspect you've been spoofed there are steps you can take to secure your account.
That is, the reverse DNS might verify, but it will usually be part of another domain than the claimed domain name. Using an ISP's mail server as a relay may solve the reverse DNS problem, because the requirement is the forward and reverse lookup for the sending relay have to match, it does not have to be related to the from-field or sending ...
Spoofing happens when someone sends emails making it look like it they were sent from your account. In reality, the emails are sent through a spoofer's non-AOL server. They show your address in the "From" field to trick people into opening them and potentially infecting their accounts and computers. Differences between hacked and spoofed
DNS servers are computers responsible for resolving Internet names into their real IP addresses. Compromised DNS servers are sometimes referred to as "poisoned" . Pharming requires unprotected access to target a computer, such as altering a customer's home computer, rather than a corporate business server.
