Which attack involves redirecting a user to a malicious website through altered URLs?

Hyperlink spoofing is a type of attack that focuses on deceiving users into clicking on links that appear legitimate but redirect them to malicious websites. This is often achieved by altering the URLs in a way that they look similar to trusted sites, yet lead to harmful destinations. Attackers may use techniques such as modifying HTML or creating deceptive text hyperlinks that mislead users about the true target of a link.

In this context, users may unknowingly share sensitive information on these malicious sites, believing they are interacting with a trustworthy service. Examples of hyperlink spoofing include phishing attacks, where attackers craft emails with links that appear to direct users to a legitimate login page but actually lead to a fraudulent site designed to steal credentials.

The other types of attacks listed do not involve redirecting users through altered URLs. Random code execution relates to executing arbitrary code, replay attacks focus on intercepting and reusing valid packets of communication, and denial of service attacks overwhelm a system to make it unavailable. None of these directly involve the deception of users through misleading URLs, which is the hallmark of hyperlink spoofing.
