  • Domain Name System vulnerability exploitation attackDNS vulnerability exploitation attack

    An attack in which the attacker takes advantage of a vulnerability (e.g., a bug or a security hole) in the DNS server software. Some attackers use this form of attack to disable a name server. For example, they might craft an unorthodox DNS message to cause a targeted name server to fail. Other attackers exploit vulnerabilities that allow them to gain administrative control over a name server.
