What is a pharming attack primarily designed to do?

A pharming attack is primarily designed to redirect users from legitimate websites to fraudulent ones without their knowledge. This technique manipulates the way internet addresses are resolved, often compromising the integrity of the user's browser experience. When successful, users may inadvertently provide sensitive information, such as usernames, passwords, and financial details, to attackers disguised as a trusted entity.

This type of attack is particularly insidious because victims may not even realize that they have been directed to a bogus site, which can look almost identical to the authentic website. The goal of the attack is to manipulate web traffic, making option B the accurate answer. Other options, while related to cybersecurity threats, do not accurately characterize the primary objective of a pharming attack.
