Whaling is a highly targeted form of phishing attack aimed specifically at senior executives or high-profile individuals within an organization, such as CEOs or CFOs. Unlike generic phishing, whaling attacks are carefully crafted and personalized, often using information gleaned from public sources or social media to increase credibility. The attackers impersonate trusted contacts or official entities to deceive the target into revealing sensitive information, transferring funds, or taking other actions that compromise security. Because of the significant authority and access that executives have, successful whaling attacks can lead to severe financial losses, data breaches, and reputational damage for organizations. Awareness and specialized security training are essential defenses against whaling.
