A whaling cyber attack is when fraudsters target specific higher-ranking employees in a company. By impersonating a senior executive, they try to extract sensitive information or money from their victims. They do this by sending emails or trying to contact employees in other ways (social media, instant messaging, even a phone call, etc.). Usually, they ask to send something quickly because they need it as soon as possible. There is typically a sense of urgency in whaling messages.

They can even contact the company’s employees just to get the organization’s tone of voice and communication patterns. Due to its highly personalized nature, this social engineering technique is difficult to detect and can affect even very cautious users.
While whaling uses similar techniques to phishing, it is also significantly different. Phishing is the blasting of non-personalized emails to lots of random people, hoping to trick some of them. This usually involves generic requests like asking to click on a link, entering your credentials, etc. Phishing emails are easier to identify for the average user as they are not as well-researched and carefully crafted as whaling messages. Phishing emails have low success rates.
