A user receives an email about an unfamiliar bank transaction, which includes a link. When clicked, the link redirects the user to a web page that…

The scenario describes a classic phishing attack. Phishing is a form of social engineering where an attacker uses a fraudulent electronic communication, typically email, to masquerade as a trustworthy entity. The goal is to deceive the recipient into revealing sensitive information, such as login credentials or financial details. In this case, the attacker uses a deceptive email about a bank transaction to lure the user to a spoofed website designed to harvest their username and password. This method aligns perfectly with the definition of phishing.

A. Whaling: This is a more specific form of phishing that exclusively targets high-profile individuals like executives or senior management.

B. Smishing: This attack is a variant of phishing that uses SMS (text messages) as the delivery vector, not email.

C. Vishing: This attack, also known as voice phishing, uses voice communication (e.g., phone calls) to conduct the social engineering attack.

Section II-A

Phishing Definition: This peer-reviewed article defines phishing as "a fraudulent attempt

usually made through email

to steal personal information." It further distinguishes it from vishing and smishing based on the communication channel used. (DOI: https://doi.org/10.1109/SURV.2013.032213.00067)
