DNS Security Attacks

Cache Poisoning using Name Chaining Victim issues a query Atacker injects DNS names into the response of RR’s and can reroute subsequent DNS queries to another server This is achieved by means of DNS RRs(resource records) whose RDATA portion includes a DNS name which can be used as a hook to let an attacker feed bad data into a victim’s cache. The most affected types of RRs are CNAME, NS, and DNAME(alias for the whole DNS domain) RRs.
