What is Business Email Compromise (BEC)?

BEC (Business Email Compromise) scams are a type of fraud that occurs when a cybercriminal gains unauthorized access to an organization's email account or spoofs the email of a trusted source and requests sensitive information or funds. The fraudster impersonates a high-level executive, a trusted supplier, or another authority figure and tricks the recipient into sending money or sensitive information to the attacker's account. These scams can cause significant financial losses to individuals and organizations and result in the loss of sensitive data. To protect against BEC scams, verifying the sender's identity before responding to emails requesting sensitive information or funds, implementing strong email security measures, and educating employees on how to recognize and respond to such scams is recommended.

BEC scams are becoming increasingly sophisticated and challenging to detect, with attackers using tactics such as spear phishing, social engineering, and impersonation to trick victims into giving them access to sensitive information or funds. For example, a BEC scammer might email an employee posing as a high-level executive within the company and request a transfer of funds to a specific bank account. The email looks like it's coming from a legitimate email address and may be formatted like the executive's email.

In other cases, a BEC scammer might compromise an email account belonging to a trusted vendor, supplier, or business partner and then send requests for payment to the victim's company using the compromised email account. This type of BEC scam is known as "spoofing."

BEC scams can result in significant financial losses, especially for targeted organizations. For this reason, it's vital for individuals and organizations to be aware of the signs of a BEC scam and to take steps to protect themselves. Some steps that organizations can take include implementing multi-factor authentication for email accounts, regularly reviewing account activity for signs of unauthorized access, and educating employees on how to recognize and respond to BEC scams. Additionally, it's essential to be cautious when receiving requests for sensitive information or funds and to verify the sender's identity before responding.

Types of BEC Attacks?

Business Email Compromise (BEC) attacks constantly evolve and can take many forms. Each BEC attack has unique characteristics and tactics, from CEO fraud to vendor compromise, invoice fraud, attorney impersonation, domain spoofing, and data theft. Understanding the different types of BEC attacks is crucial to preventing them and protecting your organization. In this section, we will delve into each type of BEC attack and explore the methods used by attackers. There are several different types of BEC scams, including:

CEO Fraud: 

CEO Fraud, also known as "CEO Scam" or "CEO Impersonation Fraud," is a type of Business Email Compromise (BEC) scam in which the attacker poses as the CEO or another high-level executive of a company and requests sensitive information or funds from an employee. The attacker will often use publicly available information about the executive and the company to craft a convincing email that appears to come from the executive's email account.

In a typical CEO Fraud scenario, the attacker will send an email to an employee in the finance or accounting department and request a wire transfer or sensitive information. The email may appear urgent, and the attacker may use language or a tone of authority to convince the recipient to act quickly.

This scam can cause significant financial losses, especially if the employee falls for the scam and sends the requested funds to the attacker's account. In some cases, the attacker may also gain access to sensitive financial information or login credentials that can be used for future attacks.

Vendor Email Compromise: 

Vendor Email Compromise (VEC) is a type of Business Email Compromise (BEC) scam where a cybercriminal gains unauthorized access to the email account of a trusted vendor, supplier, or business partner. The attacker then sends an email to the victim's company, posing as the vendor, and requests payment for an invoice or other expense.

In a VEC scam, the attacker's email may appear to come from the vendor's legitimate email address. They may use language and tone consistent with the vendor's communication style. This makes the scam challenging to detect and increases the chances of the victim falling for it.

If the victim sends the requested payment to the attacker's account, the attacker will have access to the funds, which can result in significant financial losses for the victim.

It is important for organizations to be aware of VEC scams and to educate their employees on how to recognize and respond to these types of attacks.

Invoice Fraud: 

Invoice Fraud is a type of Business Email Compromise (BEC) scam in which an attacker poses as a vendor or supplier and sends a fake invoice to the victim's company, requesting payment. The invoice may appear to come from a legitimate vendor or supplier, but the attacker will often use a different payment address or bank account number than the one used by the genuine vendor.

In a typical invoice fraud scenario, the attacker will email an employee in the finance or accounting department and request payment for a supposedly overdue invoice. The email may appear to come from the vendor's legitimate email address, and the attacker may use language or a tone consistent with the vendor's usual communication style.

If the victim falls for the scam and sends the payment to the attacker's account, the attacker will then have access to the funds, which can result in significant financial losses for the victim.

Attorney Impersonation Fraud: 

Attorney Impersonation Fraud is a type of Business Email Compromise (BEC) scam in which an attacker poses as an attorney and sends an email to a victim requesting sensitive information or payment. The attacker may use the name and contact information of an actual attorney or law firm, or they may create a fake email address that appears to belong to a legitimate attorney.

In a typical attorney impersonation fraud scenario, the attacker will email the victim, claiming to be an attorney working on a legal matter. The email may contain language or tone consistent with how an attorney would communicate, and the attacker may use official-sounding terms and legal jargon to make the email appear more credible.

The attacker may request payment for legal services or sensitive information such as confidential documents, passwords, or banking information. Suppose the victim falls for the scam and provides the requested information or payment. In that case, the attacker will access the victim's sensitive information or funds, which can result in significant financial losses or other harm.

Domain Spoofing: 

Domain Spoofing is a technique used by attackers in Business Email Compromise (BEC) scams to make an email appear to come from a trusted source when it is from a different, often malicious, source. The attacker will manipulate the "From" address in the email header to make it appear that the email comes from a trusted domain, such as a company's domain or a domain associated with a trusted vendor or business partner.

In a typical domain spoofing scenario, the attacker will send an email to the victim that appears to come from a trusted source, such as a CEO or a vendor. The email may request sensitive information, such as login credentials, financial information, or payment for an invoice or other expense.

Suppose the victim falls for the scam and provides the requested information or payment. In that case, the attacker will then have access to the victim's sensitive information or funds, which can result in significant financial losses or other harm.

Data Theft: 

Data Theft refers to the unauthorized acquisition of sensitive or confidential information, often for financial gain or to cause harm to the victim. Data theft can occur in several ways, including phishing scams, malware attacks, or exploiting computer system vulnerabilities.

In a typical data theft scenario, the attacker will use various techniques to steal sensitive information, such as login credentials, financial information, or personal data. The attacker may use social engineering techniques to trick the victim into providing the information or use malware to infect the victim's computer and steal the information directly.

Once the attacker has obtained the sensitive information, they may use it for financial gains, such as by selling the information on the dark web or stealing money from the victim's bank account. They may also use the information to cause harm to the victim, such as by using it to commit identity theft or to blackmail the victim.

How Common are BEC Scams?

Business Email Compromise (BEC) scams are becoming increasingly common and pose a significant threat to organizations of all sizes. According to the FBI's Internet Crime Complaint Center (IC3), BEC scams have resulted in billions of dollars in losses globally and are one of the fastest-growing types of financial crimes. In 2020, the IC3 received 22,000 BEC/E-mail Account Compromise (EAC) complaints, with reported losses exceeding $1.9 billion. These numbers indicate how widespread and devastating BEC scams can be and underscore the importance of staying informed and taking proactive measures to protect your organization.

How to Prevent BEC Attacks?

These sophisticated scams target organizations and result in massive financial losses and reputational damage. But the good news is, with suitable measures in place, you can protect your business from falling prey to these attacks. A comprehensive approach that combines technical and non-technical measures is critical to safeguarding your organization. Here are some measures to protect your business from BEC scams.

Employee education and training: 

This includes regular training sessions and awareness programs for employees to understand the tactics used in BEC scams and how to identify and avoid them. This can include providing examples of common scams, teaching employees how to recognize phishing emails, and encouraging them to report suspicious emails.

Email security measures: 

Email security measures can include using anti-spam and anti-phishing tools to detect and block suspicious emails, using email filtering to separate legitimate emails from potential scams, and using encryption to protect the confidentiality of email communications. Organizations can also implement DMARC (Domain-based Message Authentication, Reporting, and Conformance) to protect against email spoofing.

Verification procedures: 

This can involve having clear procedures in place for verifying the authenticity of emails that request sensitive information or payment, such as requiring verbal confirmation from the sender or checking with another trusted source before responding to the email.

Secure communications: 

This includes encryption to protect sensitive information in transit, such as through secure email services or virtual private networks (VPNs). Organizations can also use secure file-sharing tools to exchange sensitive files securely.

Account monitoring: 

Regular bank and email accounts monitoring can help organizations quickly detect and respond to unauthorized transactions or access to sensitive information. This can include setting up alerts for large transactions or changes in account activity and regularly reviewing account activity logs.

Vulnerability management: 

This involves regularly patching software and systems to address known vulnerabilities and reduce the risk of successful attacks. This includes updating software and operating systems and implementing security updates for applications and systems.

Access controls: 

Robust access controls, including multi-factor authentication, can prevent unauthorized access to sensitive information. This involves using a combination of something the user knows (such as a password), something the user has (such as a smartphone), and something the user is (such as a fingerprint) to confirm the identity of the user.

What To Do If You Experience a BEC?

A Business Email Compromise (BEC) scam can be a stressful and damaging experience, but there is hope. Taking prompt and proactive action can minimize the damage and protect your organization from financial loss and reputational harm. If you experience a Business Email Compromise (BEC) scam, it is prudent to take immediate action to minimize the damage. The following steps can help:

Report the scam: 

If you have transferred funds due to a BEC scam, it is crucial to report the incident to your bank or financial institution as soon as possible. They may be able to recover the funds or prevent further unauthorized transactions. Additionally, you should report the scam to the FBI's Internet Crime Complaint Center (IC3) or your local law enforcement agency. This will help the authorities track down the perpetrators and prevent similar scams from happening in the future.

Preserve evidence: 

To assist investigations and recovery efforts, preserving all emails, attachments, and other relevant information related to the scam is prudent. This evidence will help you provide a clear picture of what happened and may help pursue legal action.

Change passwords: 

If you believe your email or online accounts have been compromised, change your passwords immediately and use strong, unique passwords. This will prevent the attackers from continuing to access your accounts and cause further harm.

Monitor accounts: 

Monitor your bank and email accounts closely for any unauthorized transactions or changes. Report any suspicious activity to your financial institution and relevant authorities.

Review procedures: 

After experiencing a BEC scam, it is vital to review your internal procedures and controls to determine how the scam occurred and identify any weaknesses that need to be addressed. This will help you prevent similar scams from happening in the future.

Inform employees: 

Suppose the scam involves an email impersonating a senior executive or another employee. In that case, it is essential to inform all employees about the scam and the steps to prevent similar scams. This will help increase awareness and prevent employees from falling victim to similar scams.
