Understanding Whaling in Cybersecurity

Whaling in cybersecurity is a term that has been gaining prominence in recent years. It refers to a specific type of phishing attack that targets high-profile individuals within organizations.

These attacks have surged by 131% in Q1 2021 compared to Q1 2020, according to email security company GreatHorn, and have cost organizations as much as $1.8 billion.

The report also states that executives receive a whaling attack via email at least once every 24 days, on average.

This has contributed to the spike, with 59% of organizations revealing that their executives have been the target of whaling attacks, and 46% of those falling victim.

But what exactly is whaling in cybersecurity, and what can be done about it?

Let’s dive deeper into this topic.

Defining whaling in cybersecurity

Whaling in cybersecurity is a form of phishing attack that specifically targets senior executives and other high-ranking individuals within an organisation.

The term ‘whaling’ was coined because the individuals targeted are often referred to as ‘big fish’ within their respective organizations, such as executives or CEO’s.

Unlike standard phishing attacks, which typically involve sending out mass emails in the hope that someone will click on a malicious link, whaling attacks are highly targeted and often involve a great deal of research on the part of the attacker.

This is because the ‘big fish’ are often more difficult to ‘catch’, but the potential rewards are much greater.

How whaling attacks are carried out

Whaling attacks typically involve a high degree of social engineering.

The attacker will spend time researching their target and learning about their habits, interests, and professional responsibilities.

This information is then used to craft a highly personalized and convincing email or message, designed to trick the target into revealing sensitive information or carrying out a specific action.

The attacker may impersonate a trusted individual or organization, such as a colleague, a family member, or a bank.

The message may contain a malicious link or attachment, or it may simply ask the target to carry out a task such as transferring funds or providing login credentials.

The role of spear phishing in whaling

Whaling in cybersecurity is often considered a subset of spear phishing, another type of targeted phishing attack.

While spear phishing can target any individual within an organization, whaling in cybersecurity specifically targets high-ranking individuals.

The techniques used in both types of attacks are similar, but the stakes are often much higher in whaling due to the level of access and influence that the targets have within their organizations.

Examples of whaling attacks

In recent years, there have been several high-profile cases of whaling in cybersecurity.

In one case, the CEO of a multinational company was tricked into transferring €19 million to a fraudulent account.

In another case, a high-ranking executive at a tech company was tricked into sending out W-2 tax forms for all employees, resulting in a massive data breach.

Preventing whaling attacks

Preventing whaling attacks requires a multi-faceted approach.

First and foremost, organizations need to invest in cybersecurity training for all employees, but especially for high-ranking individuals.

This training should cover the basics of phishing and whaling in cybersecurity, including how to recognize and respond to suspicious emails and messages.

Organizations should also implement strong security measures, such as two-factor authentication and secure email gateways.

These can help to prevent attackers from gaining access to sensitive information, even if a whaling attack is initially successful.

Importance of cybersecurity awareness

One of the most effective ways to prevent whaling attacks is to foster a culture of cybersecurity awareness within an organization.

This means ensuring that all employees, from the CEO down, are aware of the risks and know how to protect themselves and the organization.

Role of technology in preventing whaling

While human awareness and vigilance are crucial, technology also plays a key role in preventing whaling attacks.

Advanced threat protection solutions can help to detect and block phishing and whaling emails before they reach the inbox.

Additionally, regular system updates and patches can help to protect against known vulnerabilities that attackers may try to exploit.

Conclusion

Whaling in cybersecurity is a serious threat that organizations of all sizes need to be aware of.

By understanding what whaling is and how it works, organizations can take steps to protect themselves and their high-ranking individuals from these targeted attacks.

With the right combination of training, awareness, and technology, it is possible to significantly reduce the risk of falling victim to a whaling attack.

However, it’s important to remember that cybersecurity is an ongoing process, and organizations must remain vigilant and proactive in order to stay one step ahead of the attackers.
