In today's threat landscape, businesses face an ever-growing threat of Business Email Compromise (BEC). The median amount stolen from a BEC has increased to $50,000, according to Verizon’s 2023 DBIR report.¹

Understanding BEC and its implications is crucial for safeguarding your organization's sensitive information and financial assets.

What is Business Email Compromise (BEC)?

Business Email Compromise refers to a sophisticated form of cybercrime in which attackers manipulate or impersonate legitimate email accounts to deceive individuals within an organization. By gaining unauthorized access, they aim to trick employees into transferring funds, divulging sensitive information, or taking other detrimental actions.

BEC poses a significant threat to businesses of all sizes and industries due to its effectiveness and potentially devastating consequences.


BEC by Industry

In 2021, the global financial sector reported the highest number of spam and credential phishing attempts. The industry saw over 3.4 million attempts of phishing attacks during the last measured period. Healthcare was the second most-targeted industry, with 3.42 million phishing attempts. The education sector ranked third, with 3.2 million phishing attempts in the examined year.

Types of Business Email Compromise Attacks

There are five main types of BEC, according to the FBI.

Account Compromise

In an account compromise, attackers gain unauthorized access to employee or vendor accounts to facilitate fraudulent transactions. Email account compromises can be especially dangerous, as they allow the attacker to use a legitimate company email to facilitate their attacks.

Attorney Impersonation

Exploiting legal contexts, attackers may pose as attorneys to deceive organizations and orchestrate fraudulent activities. Attackers will pose as a lawyer or legal team and manipulate an employee into sending sensitive information or even performing a wire transfer.

CEO Fraud

Impersonating high-ranking executives, attackers request urgent financial transactions or confidential information. Without careful inspection of an email, employees can hastily send sensitive information or financial data to a scammer.

Data Theft

BEC attacks may also focus on stealing sensitive information, such as customer or employee data, intellectual property, or financial records. Attackers use social engineering techniques to trick employees into sharing login credentials or providing access to secure systems. This data can then be used in future advanced attacks or sold onto the dark web.

Invoice Fraud

In an invoice fraud attack, the attacker impersonates a legitimate vendor or supplier. They email the targeted organization, usually the accounting department, providing updated payment instructions or requesting payment for fraudulent invoices.

Business Impact of a Business Email Compromise

Financial Losses

A successful BEC attack can result in substantial monetary losses. Generally, wire transfers cannot be reversed. If you file a cancellation notice with your bank before the recipient bank has accepted the transfer, the transfer may be refused - but if your recipient’s bank has already accepted your wire transfer, unfortunately, your options are limited, according to experts at MoneyTrasfers.com³.

Data Leakage

In many cases, BECs may result in data theft. This can lead to data leakage, where sensitive data is sent outside the organization. Data can end up accessible to the public, used in malicious ransom campaigns, or sold on the dark web. It is crucial to monitor for data leakage after a BEC.

Reputational Damage

Falling victim to BEC can tarnish a company's reputation and erode customer trust, leading to potential customer and vendor loss.

Legal and Regulatory Consequences

Businesses may face legal liabilities, compliance violations, and regulatory penalties due to compromised data and privacy breaches.


Business Email Compromise poses a significant threat to organizations, with far-reaching financial, reputational, and legal implications. Organizations should implement strong email security measures, educate employees about these threats, and maintain a robust cybersecurity posture to defend against BEC attacks.
