Business Email Compromise (BEC) Attacks on the Rise: How to Stay Safe

In recent years, cybercriminals have been increasingly targeting businesses with sophisticated email scams known as Business Email Compromise (BEC) attacks. These attacks have resulted in significant financial losses for organizations worldwide, with the FBI estimating that BEC scams have cost businesses over $26 billion since 2016. In this article, we will explore the growing threat of BEC attacks, discuss some high-profile cases, and provide actionable tips for businesses to protect themselves from falling victim to these scams.

Understanding BEC Attacks

Business Email Compromise (BEC) is a type of phishing attack where cybercriminals impersonate a high-ranking executive or trusted vendor to trick employees into transferring funds or revealing sensitive information. These attacks are highly targeted and often involve extensive research on the part of the attacker to make the fraudulent email appear as legitimate as possible. Some common tactics used in BEC attacks include:

  • Domain spoofing: Attackers create a fake email domain that closely resembles the target company’s domain to make the email appear more credible.
  • Display name deception: Cybercriminals use a display name that matches the name of a high-ranking executive or trusted vendor to trick the recipient into thinking the email is genuine.
  • Compromised email accounts: In some cases, attackers gain access to a legitimate email account within the target organization and use it to send fraudulent emails.

Notable BEC Attack Cases

Several high-profile cases of BEC attacks have made headlines in recent years, highlighting the growing threat to businesses of all sizes. Some notable examples include:

  • In 2016, toy manufacturer Mattel fell victim to a BEC attack that resulted in a loss of $3 million. The attackers impersonated a high-ranking executive and requested an urgent wire transfer to a Chinese bank account. Fortunately, Mattel was able to recover the funds due to a timely intervention by Chinese authorities.
  • In 2018, a Lithuanian man was arrested for conducting a BEC scam that targeted Google and Facebook. The attacker impersonated a Taiwanese hardware manufacturer and tricked the tech giants into transferring over $100 million to his bank accounts.
  • In 2019, the city of Ocala, Florida, lost $742,000 in a BEC attack. The attackers posed as a construction company working on a city project and requested a change in payment method, leading to the funds being transferred to the criminals’ bank account.

How to Protect Your Business from BEC Attacks

Given the significant financial and reputational risks associated with BEC attacks, it is crucial for businesses to take proactive steps to protect themselves. Here are some best practices to help safeguard your organization from falling victim to these scams:

1. Implement Strong Email Security Measures

Ensure that your organization has robust email security measures in place, such as:

  • Using email authentication protocols like DMARC, DKIM, and SPF to help prevent domain spoofing.
  • Implementing email filtering solutions to detect and block phishing emails.
  • Regularly updating and patching email systems to protect against known vulnerabilities.

2. Educate Employees on BEC Attack Tactics

Conduct regular security awareness training for employees to help them recognize and report potential BEC attacks. This should include:

  • Teaching employees how to spot common BEC tactics, such as domain spoofing and display name deception.
  • Encouraging employees to verify the legitimacy of any unusual or unexpected email requests, especially those involving financial transactions or sensitive information.
  • Establishing clear reporting procedures for employees to follow if they suspect a BEC attack.

3. Establish Strict Financial Controls

Implement strict financial controls to help prevent unauthorized transactions, such as:

  • Requiring multi-factor authentication for any changes to payment details or wire transfer requests.
  • Implementing a dual-approval process for high-value transactions, where two authorized individuals must approve the transaction before it can be processed.
  • Regularly auditing and monitoring financial transactions to detect any suspicious activity.

4. Develop a Comprehensive Incident Response Plan

Having a well-defined incident response plan in place can help your organization quickly detect, contain, and recover from a BEC attack. This plan should include:

  • Clearly defined roles and responsibilities for key personnel during a security incident.
  • Procedures for reporting and escalating suspected BEC attacks.
  • Guidelines for communicating with employees, customers, and other stakeholders during a security incident.
  • Regular testing and updating of the incident response plan to ensure its effectiveness.


As Business Email Compromise (BEC) attacks continue to rise, it is essential for organizations to take proactive steps to protect themselves from these costly scams. By implementing strong email security measures, educating employees on BEC attack tactics, establishing strict financial controls, and developing a comprehensive incident response plan, businesses can significantly reduce their risk of falling victim to these sophisticated cyber threats.
