Executive Summary
Whaling attacks represent a highly targeted form of spear phishing directed at senior executives and high-level leadership. These attacks exploit the authority and access privileges of C-suite personnel, making them valuable targets for financial fraud, data theft, and business email compromise. Attackers craft convincing messages impersonating trusted contacts, legal counsel, or board members to manipulate executives into transferring funds or revealing sensitive credentials. The high-value nature of these targets means even a single successful attack can result in significant financial losses and reputational damage. Organizations should implement multi-factor authentication, email filtering, and executive-specific security awareness training to mitigate this threat.
