Cache poisoning is a kind of attack in which corrupted data is inserted into the cache database of DNS(Domain Name System) name server. The Domain Name System ( DNS ) is a system which associates domain names with respective IP addresses. Devices which are connected to the internet or a private network rely on the DNS for resolving URLs into their corresponding IP addresses.

The new IP address is most likely controlled by the attacker and is used to spread computer worms and other malware. Other sophisticated uses for DNS cache poisoning include denial-of-service attacks and man-in-the-middle attacks.
