Question

Give three different techniques that an attacker can use to make a victim send DNS requests to domains chosen by the attacker.

Answer 1

Answer;

A DNS (Domain Name System) attack exploits the DNS towards land the user on a wrong website or server. They are three types of DNS attacks are:

1. Pharming
2. Phishing
3. DNS cache poisoning

Now,

Pharming:

• Here using pharming attack, the attacker can forge the genuine website through using DNS server software.
• The victim believes it as real website then provides true information.

Phishing:

• In this phishing attack, pharming attack provides mutual support.
• After a fake website is created and presented in front of user, he/she assumes it as genuine site and provides it through all sensitive information such as email password, online banking information, and credit card details.
• These are collected at the fake sites and used later without bringing to the notice of the owner.

DNS Cache Poisoning:

• DNS Cache Poisoning is an attack in which the attacker exploits the vulnerabilities of the DNS system by directing the Internet traffic from the trusted servers to the fraudulent servers which resemble the trusted one.
• In this exploit, the DNS cache is tricked to store a false DNS record.
