Executive phishing, also known as “chief executive officer (CEO) fraud” or “whaling,” is a type of cyber attack that explicitly targets high-level executives or individuals in prominent positions within an organization. It’s a more sophisticated and targeted form of phishing that aims to trick senior executives into disclosing sensitive information or performing specific actions that can harm the target company.
Executive phishing’s goal? To exploit the authority and trust associated with high-ranking executives to manipulate employees or gain unauthorized access to sensitive data or systems.

How Do Attackers Perform Executive Phishing?
Here are the steps attackers typically take to perform executive phishing.
- Attackers carefully research their targets to gather information that can make their pending impersonation convincing. They may use publicly available information, such as that seen on corporate websites, social media profiles, or press releases, to craft personalized and believable messages.
- Using social engineering techniques, attackers impersonate a senior executive, such as a company’s CEO or chief financial officer (CFO).
- Attackers can use various communication means. They may send fraudulent emails, make fake phone calls, or use other devices to deceive the target. What’s important is that the messages or calls appear urgent. They also often involve requests for confidential information, financial transactions, or access to sensitive systems.
- Attackers may also use techniques like email spoofing to make the communication appear to come from a legitimate source.

How Can Organizations Protect against Executive Phishing?
Companies can take several measures to protect against executive phishing, such as these critical strategies.
- Employee education and awareness: Conduct regular training programs to educate employees about the risks and characteristics of cyber attacks, including executive phishing. Teach them how to identify suspicious emails, recognize social engineering techniques, and promptly report suspicious activity.
- Strong email security measures: Deploy email filtering and monitoring solutions to detect and block phishing emails, including those attempting to impersonate executives. These solutions can analyze email headers, domains, and content to identify potential phishing attempts.
- Multifactor authentication (MFA): Enable MFA for all critical systems and accounts to add an extra layer of security by requiring additional verification. An example would be a unique code sent to a mobile device on top of a username-password combination. Even if attackers obtain an employee’s login credentials, MFA can help prevent unauthorized access.
- Robust password policies: Implement and enforce strong password policies organization-wide. Encourage employees to use unique, complex passwords and regularly update them. Discourage password sharing and ensure that default or weak passwords aren’t employed.
- Secure communication channels: Establish secure communication channels, such as encrypted email services or secure messaging platforms, for sensitive information sharing within the organization. Encourage employees to use these channels when discussing confidential or sensitive matters.
- Incident response and reporting: Develop a clear incident response plan that outlines steps to take in the event of a phishing attack. Encourage employees to promptly report any suspicious email or incident so appropriate action can be taken to mitigate the impact.
- Independent request verification: Encourage employees to independently verify any unusual or urgent request, especially if it involves sensitive information or financial transactions. Directly contact the supposed sender using a known and verified contact method rather than solely relying on the communication received.
- Regular security updates: Keep all software, applications, and systems updated with the latest security patches and updates to protect against known vulnerabilities that attackers may exploit.
- Robust access controls: Implement strict access controls and permissions for critical systems and sensitive data. Only provide access to authorized individuals based on the principle of least privilege, ensuring that employees have access only to the resources they need for their roles.
- Ongoing monitoring and testing: Regularly monitor network traffic, email systems, and user behaviors for signs of phishing. Conduct periodic attack simulations and tests to evaluate employees’ readiness and identify areas that require further training and improvement.

Remember that protecting against executive phishing requires a multilayered approach that combines technology usage, employee education, and robust security practices throughout your company.
Key Takeaways
- Executive phishing, CEO fraud, or whaling refers to a cyber attack targeting high-level executives or individuals in prominent organizational positions.
- Thorough research about spoofing targets—executives who will be impersonated—is necessary for CEO fraud. That said, C-suites must be careful not to reveal too much online.
- Employee education and awareness, strong email security measures, MFA, robust password policies, secure communication channels, incident response and reporting, independent request verification, regular security updates, strong access controls, and ongoing monitoring and testing are ways to avoid becoming executive phishing victims.
