Explanation
DNS poisoning, also known as DNS spoofing or DNS cache poisoning, is a form of computer security hacking in which corrupt Domain Name System (DNS) data is introduced into the DNS resolver's cache, causing the name server to return an incorrect result record, such as an IP address. This results in traffic being diverted to the attacker's computer (or any other malicious destination).
DNS poisoning can be performed by various methods, such as:
* Intercepting and forging DNS responses from legitimate servers
* Compromising DNS servers and altering their records
* Exploiting vulnerabilities in DNS protocols or implementations
* Sending malicious emails or links that trigger DNS queries with poisoned responses According to CompTIA Security+ SY0-601 Exam Objectives 1.4 Given a scenario, analyze potential indicators to determine the type of attack:
