Abstract: Detecting a Domain Name Service (DNS) hijacking includes resolving names in a hijack target group list to their respective Internet Protocol (IP) addresses. In response to determining that two names in the hijack target group list resolved to a common IP address, a determination is made whether a legitimate reason exists for the two names in the hijack target group list to resolve to the common IP address. In response to determining that a legitimate reason does not exist for the two names in the hijack target group list to resolve to a common IP address, a DNS hijacking is indicated.
