What is Whaling?
Whaling is a form of spear phishing that specifically targets senior executives, board members, and other high-value individuals within an organization. The term reflects the attackers' focus on "big fish": individuals with authority to approve wire transfers, access sensitive data, or make decisions that can be exploited.
How Whaling Works
Whaling attacks are extensively researched and highly personalized. Attackers study the target's public profile, recent activities, business relationships, and communication style. The resulting attack may impersonate a board member, a legal firm, a regulator, or a business partner - and the message will reference real deals, real events, or real relationships. Because executives often operate with less technical oversight and more authority, whaling attacks that succeed can cause outsized damage.
Why Whaling Matters
Executives are prime targets because they combine maximum access with maximum public exposure. A CEO's name, face, speaking schedule, and business relationships are all public. They have authority to approve financial transactions, access sensitive data, and override security procedures. According to the FBI, BEC attacks targeting executives accounted for over $2.9 billion in losses in 2023.
How to Protect Against Whaling
- Run targeted simulations specifically against senior leadership
- Profile executive exposure to understand what attackers can find about them
- Implement strict verification protocols for executive-initiated financial requests
- Limit executive data available in public channels where possible
- Ensure executives receive the same (or more intensive) security testing as all employees
