Business Email Compromise: Definition and Examples

Business email compromise (BEC) is a growing threat that can have severe consequences for your organization. These attacks involve cybercriminals gaining access to your company’s email system and using it to trick employees into transferring funds, sharing sensitive data, or carrying out other fraudulent activities.

BEC attacks can take many forms, and it’s essential to be aware of the different tactics used by cybercriminals. Some of the most common types of BEC attacks include:

BEC Attack TypeExample
CEO FraudA cybercriminal poses as the CEO and emails an employee requesting a transfer of funds to a specified account.
Invoice ScamsA supplier’s email account is hacked, and fake invoices are sent to the company requesting payment for goods or services.
Vendor ImpersonationA supplier’s email account is hacked, and the cybercriminal impersonates the supplier, requesting changes to payment details.

These examples illustrate a few of the many tactics used in BEC attacks. By understanding how these attacks work, you can proactively protect your organization and minimize the risk of financial and reputational damage.

The Mechanics Behind Business Email Compromise

Business email compromise (BEC) attacks typically begin with a hacker gaining access to an email account or creating a new one that appears to belong to a trusted sender. They then send fraudulent emails to employees, clients, or partners, aiming to trick them into making a financial transaction or divulging sensitive information.

One of the tactics used in a BEC attack is email spoofing. This involves creating an email that appears to be from a legitimate source, such as the CEO or a trusted vendor, but with a slightly altered address. For instance, the email address might be ceo@yourcompany-inc.com, instead of the correct one, ceo@yourcompany.com.

Another technique used in a BEC attack is social engineering. This involves manipulating the recipient into believing the email is genuine and trustworthy. The attacker may use tactics such as urgency, flattery, or fear to persuade the recipient to take action, such as wiring funds to a fraudulent account or clicking on a malicious link.

Impersonation is another common tactic used in BEC attacks. This involves the attacker posing as a trusted individual to gain the recipient’s confidence. For instance, they may impersonate a senior executive, vendor, or lawyer to convince the recipient to comply with their requests.

Once the recipient responds to the fraudulent email, the attacker gains access to sensitive information or initiates a fraudulent transaction. The victim may not realize they’ve been scammed until too late, and the losses can be significant.

By understanding the mechanics behind BEC, you can identify warning signs and take preventive measures to protect your business.

Red Flags and Warning Signs of Business Email Compromise

Business Email Compromise (BEC) attacks can be difficult to detect because they often involve high social engineering and impersonation. However, there are some warning signs and red flags that you can watch out for to protect yourself and your organization against BEC attacks. Being vigilant and proactive can minimize the risk of falling prey to these sophisticated scams.

Unusual or Suspicious Requests

Be wary if you receive an email requesting an unusual or suspicious action, such as sending money to an unfamiliar account or providing sensitive information like login credentials. BEC attackers often impersonate key executives or vendors to deceive employees into carrying out their requests. Always verify the requestor’s identity and legitimacy through a separate communication channel, such as a phone call or an in-person meeting.

Unexpected Changes in Payment Methods or Account Details

Be cautious if you notice unexpected payment method changes or account details. BEC attackers may tamper with vendor invoices or alter payment information to redirect funds into their own accounts. Always verify payment details with trusted third-party contacts before making any transfers or changes.

Sudden Changes in Communication Patterns

If you notice sudden changes in the communication patterns of your email contacts, such as unusual language or tone, be alert. BEC attackers may hijack email accounts and use them to launch phishing campaigns or solicit sensitive information. Always be suspicious of emails that deviate from normal communication patterns, and verify the sender’s identity and intention before responding.

By recognizing the red flags and warning signs of BEC attacks, you can protect yourself and your organization against potential threats. Remember to be cautious and vigilant in your email communications, and always verify the identity and legitimacy of requestors and senders. With these precautions in place, you can minimize the risk of falling victim to BEC scams and safeguard your organization against cyber threats.

Protecting Your Business from BEC Attacks

Preventing BEC attacks requires a multi-pronged approach that involves employee training, cybersecurity measures, and email authentication protocols. Here are some actionable tips and strategies to protect your business:

  • Train your employees: The first step in protecting your business is to educate your employees about the dangers of BEC and how to spot suspicious emails. Conduct regular awareness programs and training sessions to keep your workforce informed.
  • Secure your email system: Implement robust email authentication protocols such as Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC). These measures help prevent email spoofing and protect your organization’s email reputation.
  • Use multi-factor authentication: Require multi-factor authentication for all email accounts and sensitive data access. This adds an extra layer of security to protect against unauthorized access.
  • Establish strict payment protocols: Rigorous payment protocols include verifying all invoices and payment requests, confirming the recipient’s identity, and verifying the payment details. Avoid processing payments based on email or phone instructions alone.

Implementing these measures can significantly reduce the likelihood of a successful BEC attack and protect your business against financial loss and reputational damage.

Common Business Email Compromise Schemes to Watch Out For

Business email compromise (BEC) attacks can take various forms, each with the potential to cause significant damage. Understanding these schemes allows you to identify warning signs and implement effective countermeasures to prevent BEC incidents. Here are some of the most common BEC schemes to watch out for:

Ceo Fraud

In this scam, cybercriminals send targeted emails to employees with access to financial accounts, posing as the company’s CEO or another high-ranking executive. The email typically requests an urgent wire transfer or payment to a vendor, providing fake authorization and account details. The attackers manipulate employees into carrying out the unauthorized transaction by employing social engineering techniques and imitating the executive’s communication style.

Invoice Scams

In this scheme, cybercriminals target businesses that regularly transfer money to vendors or suppliers. The attackers send a fake invoice, often using a compromised email account of a legitimate vendor, requesting payment for goods or services. The invoice includes fraudulent payment information, directing the funds to the attacker’s account. By the time the fraud is discovered, the funds have usually been transferred to multiple accounts, making recovery impossible.

Vendor Impersonation

This scam targets businesses that maintain relationships with multiple vendors or suppliers. The attackers impersonate a known vendor, sending an email requesting payment for a recent transaction. The email typically contains a fake invoice or account information, directing the payment to the attacker’s account. By exploiting the trust-based relationship between the business and vendor, the attackers often successfully trick employees into transferring funds to the fraudulent account.

By being aware of these and other BEC schemes, you can educate your employees and establish robust protocols to mitigate the risks posed by these attacks. Stay vigilant and keep your organization safe from the threat of business email compromise.

Reporting and Responding to Business Email Compromise Incidents

Protecting your business from BEC attacks is crucial, but it’s also important to have a plan in place for when an incident occurs. Responding promptly can minimize the damage and increase the chances of identifying the perpetrators.

If you suspect that a BEC attack has taken place, you should:

  • Secure your email system: Disable compromised accounts and change passwords immediately.
  • Notify affected parties: Inform any potential victims, including employees, partners, and customers, of the incident.
  • Report to law enforcement: Contact your local or federal law enforcement agency and provide all relevant information about the incident.

Remember, reporting incidents of BEC attacks not only helps to protect your business but also helps to identify and bring to justice those responsible for the attack.

Proactive Measures for BEC Prevention and Mitigation

As cyber threats become more sophisticated, adopting proactive measures to protect your business from Business Email Compromise (BEC) is crucial. Here are some preventive measures to consider:
