Business Email Compromise: All You Need to Know

Business Email Compromise - Verito Technologies

If you are working in the field of tax, finance, or accounting, you would agree that every decimal point matters. The advent of the digital era has brought both convenience and peril for professionals like you. There have been new means coming into the picture to infiltrate defenses – one of which is the Business Email Compromise (BEC).

Think of BEC as the modern-day Trojan horse – a deceptive intrusion that threatens the very core of financial operations. To better understand this, consider this analogy –

Picture your financial domain as a bustling city with vital trade routes guarded by financial sentinels who examine every document entering and leaving the city gates. A sophisticated infiltrator, armed with cunning tactics, manages to forge documents so convincing that even the most vigilant sentinels are deceived. This infiltrator doesn’t storm the gates with brute force but manipulates trust, exploits vulnerabilities, and slyly gains entry.

Such is the nature of Business Email Compromise attacks in tax and accounting. Cybercriminals have become adept at impersonating trusted entities, manipulating email communication, and orchestrating fraudulent transactions, often with devastating consequences. 

This blog post serves as a comprehensive guide to illuminate the shadows of Business Email Compromise, its evolving tactics, and, most importantly, the strategies to prevent the aftermath.

What is Business Email Compromise?

At its core, BEC is a type of cybercrime where attackers gain unauthorized access to a legitimate business email account. Once inside, they exploit this foothold to deceive, manipulate, and defraud. 

What makes BEC particularly insidious is its ability to masquerade as trusted entities, often leveraging social engineering to dupe unsuspecting recipients. Here are some of its key characteristics:

  • Attackers often pose as executives, colleagues, or trusted vendors within the compromised email account. This impersonation is crafted with meticulous detail, including the use of legitimate email addresses, signatures, and language consistent with the target’s communication style.
  • BEC also relies on psychological manipulation to convince recipients to take specific actions, such as initiating wire transfers or disclosing sensitive information. By exploiting relationships and trust dynamics, attackers create plausible and urgent scenarios.
  • In some cases, these attacks even involve email spoofing where the sender’s address is manipulated to appear legitimate. This can mislead even vigilant recipients who rely on email addresses as a primary means of authentication.

The need for vigilance becomes even more apparent when you dive into the stark statistics surrounding Business Email Compromise. According to a reliable source, BEC has emerged as one of the most active attacks, reaching 35 million attempts per day. 

Let’s dive further into its types.

Types of Business Email Compromise Attacks

BEC manifests in various forms, each of which exploits different facets of email communication. Here are five prevalent categories of BEC attacks:

  • Data Theft

In this type, cybercriminals target sensitive information stored in email accounts. By gaining unauthorized access, they steal confidential data, including financial records, client details, and intellectual property, thereby posing a significant threat to the integrity of business operations.

  • CEO Fraud

As a classic in the BEC playbook, CEO fraud involves attackers impersonating high-ranking executives. They coerce employees into initiating unauthorized wire transfers or disclosing sensitive information by manipulating trust and authority, hence exploiting the hierarchical dynamics within an organization.

  • False Invoice Scheme

This tactic revolves around the manipulation of invoices. Cybercriminals intercept legitimate invoices, altering payment details to redirect funds to fraudulent accounts. This method preys on established business relationships and often leads to substantial financial losses before detection.

  • Account Compromise

Another potent category of BEC attacks involves unauthorized access to employee email accounts. Once infiltrated, attackers monitor communication, seeking opportunities to initiate fraudulent transactions, glean sensitive information, or exploit the compromised account for further malicious activities.

  • Lawyer Impersonation

This scheme involves cybercriminals posing as lawyers or legal representatives to exploit the credibility associated with these professionals. Attackers manipulate victims into divulging confidential information by leveraging the trust placed in legal entities, hence facilitating fraudulent transactions or gaining unauthorized access.

How Do BEC Scams Work?

Here’s a concise breakdown of the typical stages of a BEC scam:

  • Targeted research

Scammers conduct thorough research on their targets and dive into the details that allow them to impersonate individuals or organizations convincingly. This may involve creating fake websites or registering entities with similar names in different locations.

  • Infiltration and monitoring

After gaining access to an email account, scammers monitor communications and focus on understanding financial transactions, identifying key individuals involved, and studying communication patterns.

  • Email impersonation

During an email exchange, scammers impersonate one of the parties by employing email domain spoofing. This can involve subtle alterations to the email address (e.g., changing a letter) or presenting the correct email address “via” a different domain 

  • Building trust and deception

The scammer then builds trust with the target skillfully to exploit the impersonation and create a false sense of familiarity. Once trust is established, the scammer initiates requests for money, gift cards, or sensitive information, often under the guise of urgent or legitimate circumstances.

Common Targets of BEC Scams

  • High-ranking executives
  • Finance and accounting personnel
  • Human resources departments
  • Legal representatives
  • Vendor and supplier accounts
  • Employees with critical email access
  • Tax and accounting firms

The ramifications of a successful Business Email Compromise attack extend far beyond financial losses. Here are some of its potential dangers:

  • It can result in substantial financial losses, ranging from hundreds of thousands to millions of dollars, as scammers manipulate employees into initiating unauthorized transactions.
  • Organizations may face widespread identity theft issues in cases where personally identifiable information is stolen during a BEC attack, jeopardizing the privacy and security of employees and clients alike.
  • BEC scams may also lead to the leakage of confidential data, including intellectual property. This exposure can have severe consequences and impact both competitiveness and client trust.

How to Prevent Business Email Compromise Attacks?

Preventing BEC attacks requires a multifaceted approach combining technological defenses with employee awareness and stringent policies. Here are key strategies you can follow to safeguard your organization:

1. Employee training and awareness

  • Conduct regular training sessions to educate employees about BEC risks, red flags, and safe email practices.
  • Emphasize the importance of verifying unexpected or unusual financial requests through alternative communication channels.

2. Email authentication measures

  • Implement DMARC to validate email authenticity and reduce the risk of domain spoofing.
  • Utilize the frameworks meant to enhance email authentication and prevent unauthorized senders.

3. Advanced threat protection solutions

  • Invest in advanced email security solutions that employ machine learning and artificial intelligence to detect and block sophisticated BEC threats.
  • Update and patch email security systems regularly to stay ahead of evolving attack tactics.

4. Verification protocols for financial transactions

  • Establish verification protocols, especially for financial transactions or changes to payment details.
  • Encourage a culture of skepticism, prompting employees to verify any unexpected or high-risk requests independently.

5. Deploy Multi-Factor Authentication (MFA):

  • Enforce MFA across all sensitive accounts to add an extra layer of security.
  • Conduct periodic security audits to identify vulnerabilities and address potential weaknesses in email systems.
