Business Email Compromise (BEC) is a cyberattack where criminals trick employees into making unauthorized transactions or sharing sensitive data. It poses significant risks, including financial loss and damage to a company’s reputation. In this article, we’ll explain what BEC is, how it works, and how you can protect your business.
Understanding Business Email Compromise (BEC)
Business Email Compromise (BEC) is a targeted cyberattack where malicious actors deceive employees and executives into transferring funds or sensitive data to fraudulent accounts. Unlike mass phishing campaigns, BEC scams are highly targeted, leveraging detailed knowledge of business operations and human psychology to exploit trust and urgency. The primary goal of these attacks is to trick employees into making unauthorized financial transactions or revealing confidential information.
BEC attacks often mimic routine workflows, making it easier for attackers to catch victims off guard. For instance, fraudsters may impersonate CEOs, CFOs, or other high-level executives, sending urgent requests for financial transfers or sensitive data. These emails are crafted to appear legitimate, often using free online tools and services to enhance their realism. The simplicity and reproducibility of these scams make them an attractive option for cybercriminals, leading to a rise in BEC incidents.
The consequences of a successful BEC attack can be devastating. Businesses of all sizes face significant financial losses, productivity disruptions, and reputational damage. Poor email protection directly correlates with these security breaches, emphasizing the need for robust defenses to prevent BEC threats.
Understanding the nature and impact of BEC is the first step in fortifying your organization against these insidious attacks.
How BEC Attacks Work
Step 1: Target Selection
Cybercriminals identify high-value targets based on their access to financial resources or sensitive information. They research companies and individuals, often using publicly available data from websites, social media, or previous breaches.
Step 2: Reconnaissance & Profiling
Attackers build detailed profiles of their targets, studying email habits, communication styles, and business relationships. This helps them craft highly convincing phishing emails that appear legitimate.
Step 3: Email Spoofing & Impersonation
Using tactics like domain spoofing, lookalike domains, or compromised accounts, attackers pose as trusted vendors, executives, or business partners. They send emails that mimic real communication patterns to avoid suspicion.
Step 4: Social Engineering & Urgency
To pressure the victim into acting quickly, attackers use psychological manipulation—urgent payment requests, CEO fraud (impersonating executives), or invoice scams. The goal is to bypass normal verification procedures.
Step 5: Execution & Exploitation
Victims may be tricked into:
- Initiating wire transfers to fraudulent accounts
- Updating payment details to attacker-controlled accounts
- Sharing sensitive financial or business information
Step 6: Fund Dispersal
Once the money is transferred, attackers rapidly move it across multiple accounts, often internationally, to evade detection and recovery efforts.
Step 7: Covering Tracks & Repeating the Attack
Cybercriminals may delete emails, set up auto-forwarding rules, or use compromised accounts for further attacks, ensuring persistence and maximizing financial gain.
Common Types of BEC Scams
The FBI has identified five major types of BEC scams, each exploiting different aspects of business operations. The most common type is CEO fraud, where attackers impersonate the CEO or other high-ranking executives to request urgent financial transfers from the finance team. These fraudulent emails often appear legitimate, leveraging the authority of the impersonated executive to compel quick action.
Another prevalent scam is the bogus invoice scheme, where scammers masquerade as vendors and send altered invoices to redirect payments to fraudulent accounts. Account compromise scams involve hackers gaining access to an employee’s email account and using it to request invoice payments unauthorized payments. These attacks can be particularly effective, as they originate from a legitimate email address, making them harder to detect.
Other types of BEC scams include attorney impersonation and data theft. Attorney impersonation scams target less experienced employees with urgent legal requests, exploiting their lack of familiarity with legal procedures. Data theft attacks focus on obtaining personal information from HR or finance employees, which can then be sold or used for further malicious activities.
Understanding these common types of BEC scams can help organizations develop targeted defenses to prevent such attacks.

Key Characteristics of BEC Emails
BEC emails are crafted to appear legitimate and often include urgent requests for action, prompting immediate responses from the recipient. These emails typically lack the usual red flags like links, images, or attachments, allowing them to evade traditional malware detection methods. Instead, they rely on manipulation techniques to compel the recipient to take specific actions.
Attackers frequently spoof email addresses and impersonate trusted vendors to enhance the credibility of their messages. By referencing real events or relationships drawn from social media, they build a convincing narrative that deceives the recipient. Persuasive language is a common feature of BEC emails, designed to manipulate targets into complying with the request.
The sophisticated impersonation tactics used in BEC emails make them difficult to detect. These emails often request confidential information about employees, partners, or investors, revealing sensitive information that complicates detection efforts. The use of AI tools enables attackers to craft highly personalized and grammatically perfect emails, further challenging traditional detection methods.
Recognizing these key characteristics can help employees identify and respond to BEC threats more effectively.
Real-World Examples of BEC Incidents
Real-world examples of BEC incidents highlight the significant financial and reputational damage these attacks can cause. Between 2013 and 2015, a sophisticated BEC attack led to a financial loss of $121 million for Facebook and Google. In 2019, Toyota Boshoku Corporation suffered a $37 million loss due to a BEC scam. These incidents underscore the high stakes involved and the need for robust defenses.
FACC, an aerospace company, incurred a loss of €42 million ($47 million) in 2015 due to a BEC attack. The City of Lexington, Kentucky, lost $4 million in a BEC scam in 2022. These high-profile cases demonstrate the sophistication of BEC threats and the severe financial implications for businesses.
These examples serve as a stark reminder of the importance of proactive measures to prevent BEC attacks. By understanding the potential impact and learning from these incidents, organizations can better prepare their defenses and avoid becoming the next victim of a successful BEC attack.
Strategies for Preventing BEC Attacks
Preventing BEC attacks requires a multifaceted approach that combines technical defenses and employee training. Employing advanced email security solutions, such as email authentication protocols and anomaly detection systems, is essential for protecting against BEC threats. These technical measures help detect phishing attempts and other malicious activities, reducing the risk of successful attacks.
Regular security training and awareness campaigns are equally important. Educating employees about the tactics used in BEC scams and conducting phishing simulations can significantly improve an organization’s defenses.
Continuous monitoring and security audits are also crucial for preventing future BEC incidents. By implementing these strategies, businesses can create a robust defense against BEC attacks.

By implementing these technical measures, organizations can create a robust defense against BEC attacks. These protocols not only help prevent unauthorized access but also ensure that legitimate emails are correctly authenticated, reducing the risk of successful BEC attempts.
Domain Keys Identified Mail (DKIM)
DKIM, or DomainKeys Identified Mail, is a protocol designed to validate the authenticity of outgoing emails. It works by preventing email spoofing through the verification of email signatures against the domain’s public keys. This verification process ensures that emails are genuinely from the claimed sender, reducing the risk of fraudulent emails reaching recipients.
Implementing DKIM helps protect against email spoofing and enhances overall email security. By ensuring that only legitimate emails are delivered, DKIM plays a crucial role in mitigating BEC risks and protecting sensitive information from unauthorized access.
Sender Policy Framework (SPF)
The Sender Policy Framework (SPF) verifies email sender authenticity against approved domains. It helps prevent email spoofing by defining which mail servers are allowed to send emails on behalf of a domain. Domain owners can create a list of authorized mail servers, enhancing the legitimacy of emails and reducing the risk of fraud.
SPF ensures that only specific servers are permitted to send emails on behalf of a domain, preventing unauthorized access and enhancing email security. By implementing SPF, organizations can reduce the risk of BEC attacks and protect their communications from malicious actors.
Domain-Based Message Authentication, Reporting & Conformance (DMARC)
DMARC, or Domain-Based Message Authentication, Reporting & Conformance, allows domain owners to publish email authentication requirements, enhancing the overall security of digital communications. By aligning with protocols like DKIM and SPF, DMARC ensures that emails are properly authenticated, reducing the risk of email spoofing and other malicious activities. This alignment is crucial in identifying and mitigating potential BEC threats, as it provides a comprehensive framework for email authentication.
Additionally, DMARC enables domain owners to analyze email content for malicious intent, going beyond just validating the sender’s authenticity. This dual approach of authentication and content analysis makes DMARC a powerful tool in the fight against BEC, providing an extra layer of security to protect sensitive information and prevent unauthorized access.
Developing a Response Plan for BEC Incidents
Developing a robust response plan for BEC incidents is crucial for minimizing damage and ensuring a swift recovery. The first step in any response plan is to isolate the incident, preventing further unauthorized access or fraudulent activity. This involves immediate containment measures, such as disconnecting compromised systems from the network and securing affected email accounts.
Once the incident is contained, a thorough investigation should be conducted to assess the extent of the damage and identify the root cause of the attack. This includes analyzing email logs, reviewing financial transactions, and gathering evidence to support any legal actions. It’s also important to alert internal cybersecurity teams and notify banks if financial transactions are involved.
