Whale phishing is a highly targeted phishing attack aimed at the ‘big fishes’ of an organization – senior executives including business owners, directors, and key personnel. The attackers do some intensive research beforehand and in order to appear legitimate, the emails are presented in a personalized manner mentioning the essential details of the organization. The sender uses the email address similar to that of the taxation department or any other government body and often asks for some crucial information or money transfer. The overall impression of the email is very professional, but since it targets the higher-order smart personnel, its success rate is quite low.
