domain name registration hijacking
A form of Domain Name System (DNS) abuse in which a cyberattacker gains control over how a registered domain name is resolved. Sometimes attackers hijack a domain name by gaining control of an authoritative name server and altering the domain name’s DNS configuration in that server. In other cases, attackers hijack a domain name by gaining control of a registrant’s account with a registrar. Once the attackers have access to the account, they alter the domain name’s DNS configuration or transfer the domain name to another registrar.
