The Growing Threat of Business Email Compromise

For many leaders, cybersecurity threats often bring ransomware to mind. While ransomware continues to make headlines, another threat is quietly costing organizations billions of dollars each year: Business Email Compromise (BEC). Unlike traditional cyberattacks that rely on malware, Business Email Compromise is built on deception. Cybercriminals exploit trust, impersonate executives, vendors, clients, or business partners, and convince employees to transfer funds, share sensitive information, or change payment instructions.

As growth continues across industries such as professional services, healthcare, construction, manufacturing, technology, and nonprofit organizations, small to mid-sized businesses are becoming increasingly attractive targets for these sophisticated scams.

Key Takeaways

• Business Email Compromise (BEC) attacks target trust and business processes, making them one of the most financially damaging forms of cybercrime.
• AI-powered phishing and impersonation attacks are becoming increasingly difficult to detect, requiring stronger employee awareness and verification procedures.
• The most effective BEC prevention strategies combine technology, security training, payment controls, multifactor authentication, and ongoing risk assessments.

What Is Business Email Compromise?

Business Email Compromise is a form of cybercrime that uses email-based social engineering to manipulate employees into taking actions that benefit attackers. In many cases, criminals gain access to a legitimate email account or create a convincing lookalike address. They then pose as trusted individuals within the organization or its business network.

Common BEC scenarios include:

• Fraudulent wire transfer requests
• Fake vendor payment changes
• Executive impersonation scams
• Payroll diversion requests
• Requests for sensitive company information
• Invoice fraud targeting accounts payable teams

Because these attacks often involve legitimate-looking emails and little to no malicious software, traditional security tools may not detect them. In most cases, the best line of defense is security awareness training for your entire team.

Why SMBs Are Attractive Targets for BEC

Thriving small businesses and startup communities create significant opportunities for cybercriminals. Many of those organizations work with numerous vendors, subcontractors, suppliers, and clients. Construction firms coordinate with multiple partners. Healthcare organizations exchange sensitive information. Professional services firms manage confidential client and financial data. Manufacturers rely on complex supply chains. Startups may leverage contract employees as they build their permanent team. These interconnected relationships create an ideal environment for attackers seeking to exploit trust.

Business Email Compromise attacks are particularly effective because they target normal business processes rather than technical vulnerabilities. An employee who believes they are responding to a trusted executive or vendor may unknowingly bypass established safeguards. With the aid of AI, BEC attacks are becoming increasingly difficult to identify, often nearly flawless in their appearance and credentials. Add to that, at busy, growing businesses, the pressure to move quickly can sometimes create conditions where fraudulent requests receive less scrutiny than they should.

For business leaders, Business Email Compromise should be viewed as a financial and operational risk rather than solely a cybersecurity concern. Because these attacks often exploit business processes instead of technical vulnerabilities, organizations should periodically review approval workflows, payment procedures, and employee responsibilities to identify opportunities for fraud before attackers do. A proactive review can often reveal process gaps that technology alone cannot address.

Artificial Intelligence Is Making Attacks More Convincing

One reason BEC attacks continue to rise is the increasing use of artificial intelligence by cybercriminals. Modern phishing and impersonation emails can be crafted with professional language, proper grammar, and detailed knowledge of an organization's operations. Attackers can analyze publicly available information from websites, social media platforms, press releases, and professional networking sites to create highly personalized messages. A request that once contained obvious warning signs may now appear entirely legitimate.

For example, a client of Exigent may receive an email asking them to update auto payment information, arriving from a known Exigent email address from the lead accounting person and using a spoofed email domain that is only one small letter off: Exigemt.net vs. Exigent.net. That level of detail and accuracy can slip by even the most diligent employees. For businesses focused on growth, mergers, hiring initiatives, or expansion projects, these attacks can blend seamlessly into everyday communications.

BEC Financial Losses Can Be Significant for SMBs

Unlike ransomware attacks that often disrupt operations, Business Email Compromise frequently targets financial transactions directly. A single fraudulent wire transfer can result in losses ranging from thousands to millions of dollars. The FBI consistently identifies Business Email Compromise as one of the most financially damaging forms of cybercrime because of the direct monetary losses involved.

Beyond immediate financial impacts, organizations may also experience:

• Reputational damage
• Client trust issues
• Regulatory concerns
• Legal expenses
• Insurance complications
• Operational disruptions during investigations

In some cases, businesses do not discover the fraud until days or weeks after funds have been transferred, adding to the significant impact of the loss. Many organizations focus on preventing cyberattacks but spend less time preparing for financial fraud scenarios. Establishing relationships with financial institutions, documenting escalation procedures, and defining responsibilities before an incident occurs can significantly improve response times if fraudulent transactions are detected. When it comes to Business Email Compromise, rapid action is often critical to limiting losses.

Hybrid Work Has Increased BEC Risk

As organizations continue to work in hybrid and remote work models that provide flexibility and support employee satisfaction, those workplace scenarios can also make it more difficult to verify unusual requests through informal in-person conversations. An employee working remotely may receive an urgent email from what appears to be a company executive requesting immediate action. Without easy access to face-to-face verification, employees may feel pressured to comply quickly. Cybercriminals routinely exploit urgency, authority, and trust to increase the likelihood of success. As remote collaboration continues to evolve, businesses must adapt their security practices accordingly.

Reducing the risk of Business Email Compromise requires more than a single security tool. Effective protection requires a combination of technology, employee awareness, documented procedures, and ongoing oversight. Here are the best ways to stem the potential damage caused by BEC.

Implement Multifactor Authentication: Multifactor authentication remains one of the most effective ways to prevent unauthorized access to business email accounts. However, simply enabling it for a handful of users is not enough. Organizations should ensure multifactor authentication is enforced consistently across all users, administrative accounts, and remote access applications.

Establish Payment Verification Procedures: Many Business Email Compromise attacks succeed because employees feel pressured to act quickly. Organizations should establish documented procedures requiring independent verification before:

• Processing wire transfers
• Changing vendor banking information
• Updating payroll account details
• Approving unusual payment requests
• Sharing sensitive financial information

Verification should occur through a separate communication channel, such as a phone call to a known contact, rather than responding directly to an email request. Training your team to pause and take the time to manually confirm the request, using a known contact method outside anything shared in the email or phone message, is one of the best ways to avoid fraud.

Train Employees to Recognize Modern Phishing Attacks: Technology alone cannot stop every attack. In fact, we often discuss the imperative of training your employees about cybersecurity best practices because they are your first and best defense against nearly all attacks, but especially BEC.

Employees should understand how Business Email Compromise works and know how to identify warning signs, such as:

• Unusual urgency
• Requests that bypass normal procedures
• Changes to payment instructions
• Executive impersonation attempts
• Unexpected attachments or links

Regular cybersecurity awareness training and phishing simulations can help employees build the confidence to question suspicious requests before taking action. It also reminds them to avoid making common mistakes, such as using a link or phone number in the fraudulent email to confirm the unexpected ask.

Strengthen Email Security Controls: Modern email security platforms can help identify and block:

• Domain spoofing attempts
• Executive impersonation scams
• Malicious links
• Suspicious attachments
• Vendor payment fraud schemes

Organizations should also implement email authentication standards such as SPF, DKIM, and DMARC to reduce the risk of domain impersonation. Working with an experienced MSP is a great place to start; most offer sophisticated email filtering and DMARC services that seamlessly protect emails and data.

Review Cyber Insurance Requirements: Many cyber insurance providers now require organizations to maintain specific security controls before issuing coverage or approving claims. Not surprisingly, "I thought it was a real request," is not the answer a cyber insurance provider is looking for when and if a compromise occurs. Cyber insurance often requires:

• Multifactor authentication
• Security awareness training
• Email security protections
• Incident response planning
• Backup and recovery capabilities

Regular reviews can help organizations remain compliant while reducing financial risk, and help keep security awareness front and center with your team.

Develop and Test an Incident Response Plan: If a fraudulent payment occurs, speed matters. Organizations should establish clear procedures for:

• Reporting suspicious emails
• Escalating potential fraud incidents
• Contacting financial institutions
• Preserving evidence
• Communicating with internal stakeholders

Incident response plans should be tested regularly to ensure teams know exactly what to do during a real-world event. In industries under strict compliance controls, an incident response plan is required, making this an effort well worth the time.

Take a Proactive Approach to Risk Management: One of the most effective ways to reduce exposure to Business Email Compromise is to regularly assess security controls, business processes, and employee readiness. Many organizations discover vulnerabilities not because technology failed, but because procedures were inconsistent, employees lacked training, or risks had never been formally evaluated. Cybersecurity research routinely identifies humans as the singularly most common point of access for cybersecurity attacks of nearly every type. BEC is no different. Routine cybersecurity assessments can help identify gaps before attackers do, while ongoing security awareness training helps reinforce policies and best practices.

The most effective organizations treat Business Email Compromise prevention as an ongoing business initiative rather than a one-time security project. Regular assessments, employee training, process reviews, and technology evaluations help ensure security measures continue to evolve alongside changing business operations and emerging threats.
