Securing Business Emails Against Whaling

Securing Business Emails Against Whaling is a highly targeted email phishing attack aimed at senior executives. This $12.5 billion scam often results in the compromise of sensitive information and fraudulent wire transfers.

What Is Securing Business Emails Against Whaling?

Cybercriminals recognize that high profile executives within an organization, or “whales”, typically have complete access to sensitive data and the ability to authorize high-value wire transfers, and are valuable attack targets for this reason. Securing Business Emails Against Whaling attacks are often successful because due to the potentially high returns of these campaigns, attackers are willing to conduct extensive social engineering research on their targets to make their fraudulent emails seem as real as possible.

Anatomy of a Securing Business Emails Against Whaling Attack

The majority of whaling attacks follow four distinct phases:

Phase 1


Cybercriminals gather information available on the Internet from data breach, social media profiles and corporate websites to build their target list, identifying key executives and their relationships within an organization.

Phase 2

Build Attack

Attackers conduct extensive social engineering research to develop convincing emails impersonating an individual of authority such as the CEO or CFO of a target organization.

Phase 3

Launch Campaign

Cybercriminals launch whaling campaigns targeting the high profile executives they’ve identified in their target list. Emails sent in these campaigns do not necessarily rely on malicious links or attachments to deceive recipients. Instead, threat actors use stealthy impersonation tactics such as spoofing, look-alike domains, or display name deception.

Phase 4

Reap Rewards

A combination of urgency and trust convince the victim to proceed with the request in the malicious email, often leading to a data breach or hefty financial loss for the target organization.
