Bitsquatting is a form of cybersquatting which relies on bit-flip errors that occur during the process of making a DNS request. These bit-flips may occur due to factors such as faulty hardware or cosmic rays .
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.

Some antivirus software identifies browser hijacking software as malicious software and can remove it. Some spyware scanning programs have a browser restore function to set the user's browser settings back to ...
DNS over HTTPS (DoH) is a protocol for performing remote Domain Name System (DNS) resolution via the HTTPS protocol. A goal of the method is to increase user privacy and security by preventing eavesdropping and manipulation of DNS data by man-in-the-middle attacks [1] by using the HTTPS protocol to encrypt the data between the DoH client and the DoH-based DNS resolver.

EDNS support is also needed to allow for the much larger packet sizes that DNSSEC transactions ...
