What type of DNS attack involves conducting phishing scams by registering a similar domain name to a cloud service provider?

The correct choice is associated with the concept of registering a domain name that closely resembles that of a legitimate cloud service provider in order to deceive users into thinking they are visiting the official site. This method is commonly referred to as cybersquatting.

Cybersquatters typically exploit user confusion by creating domains that are not only similar in name but often involve minor variations such as altering a character or using a different top-level domain. When users mistakenly enter the URL of the fraudulent domain, they can be directed to phishing sites designed to harvest personal information, such as login credentials or payment details.

This practice is particularly effective due to the human tendency to not closely scrutinize web addresses. As users are lured into the trap of entering sensitive information on these fraudulent sites, the attackers can execute their phishing scams successfully. While other terms like domain hijacking or DNS poisoning involve different types of domain and DNS-related attacks, they do not specifically center around the registration of similar domain names to impersonate legitimate entities.
