Which threat vector involves the unauthorized redirection of data?

The option identifying the unauthorized redirection of data as a threat vector is Information Disclosure. This concept primarily refers to the exposure of information to individuals or systems not authorized to view it. In many scenarios, information disclosure can occur when data is unintentionally or maliciously redirected, such as when sensitive information is sent to an external destination without consent.

When we consider the context of the other threat vectors: Denial of Service focuses on disrupting access to services or systems, and Data Manipulation specifically involves altering data without authorization, which is distinct from the redirection process. Phishing Attack typically aims to deceive individuals into revealing credentials or sensitive information through fraudulent means, often leading to disclosure of information rather than directly involving redirection. Thus, the core concept of unauthorized redirection aligns most closely with the definition of Information Disclosure.
