Key topics covered in this article:

• • A recent $545,000 payment fraud incident involving a South Carolina municipality illustrates how weaknesses in payment processes, vendor management, and verification controls can lead to significant financial losses.
  • Business Email Compromise schemes increasingly target business processes rather than technology alone, exploiting trust and routine workflows to redirect payments.
  • Effective risk mitigation requires a coordinated approach that combines strong internal controls, cybersecurity safeguards, employee awareness, and well-designed operational processes.

A Financial Risk Hidden Inside a Routine Transaction

Organizations have spent years modernizing accounts payable, treasury management, and vendor payment processes. Digital workflows, ACH payments, automated approvals, and electronic vendor communications have improved efficiency and reduced administrative burden. At the same time, however, they have created new opportunities for cybercriminals to exploit trusted business processes.

A recent Ward and Smith article and related public reporting involving the Town of Surfside Beach, South Carolina, demonstrates how quickly a routine payment transaction can become a significant financial and operational challenge. According to public reports, municipal staff believed they were sending payments to a construction contractor for completed work. Instead, the funds were directed to an account controlled by a fraudster, resulting in a loss of approximately $545,000 and raising questions about responsibility, insurance coverage, and recovery efforts.
While legal questions will ultimately be resolved elsewhere, the incident offers an important lesson for business leaders, finance teams, and operational decision-makers. Payment fraud is not simply a cybersecurity issue. It is a governance, risk management, and internal controls issue that can affect organizations of any size.

When Process Efficiency Outpaces Control Design

Many organizations strive to make payment processes faster and more efficient. Automation, digital approvals, and electronic vendor communications can improve productivity, reduce manual effort, and support growth. However, when controls do not evolve alongside those efficiencies, risk can increase.
Fraudulent payment requests often succeed not because an organization lacks controls altogether, but because existing processes were designed primarily for speed and convenience rather than verification and exception handling. A fraudulent request inserted into a legitimate payment process can appear ordinary, particularly when it arrives during an active conversation between employees and vendors. The challenge for leadership is striking the right balance between operational efficiency and financial stewardship.
Organizations must create processes that enable timely payments while ensuring high-risk changes receive the scrutiny they deserve.

Why Business Email Compromise Continues to Succeed

The FBI describes Business Email Compromise as one of the most financially damaging cybercrimes affecting organizations today. In these attacks, threat actors may compromise legitimate email accounts, spoof trusted contacts, or gain visibility into ongoing business communications. Their objective is not necessarily to disrupt systems, but to redirect funds.
Unlike traditional cyberattacks that target technology infrastructure, Business Email Compromise attacks target business processes. Fraudsters often monitor legitimate conversations regarding invoices, contracts, or payment schedules before inserting fraudulent instructions at the moment a payment is expected. Because the transaction itself is real, the request may not immediately appear suspicious.
Artificial intelligence is making these schemes even more difficult to identify. Today’s fraudulent messages often contain accurate context, professional language, and convincing details that eliminate many of the red flags organizations once relied upon to detect phishing attempts.

Internal Controls Are the First Line of Defense

While cybersecurity tools can help reduce the likelihood of email compromise, internal controls determine whether a suspicious request ultimately results in a financial loss. Organizations with clearly defined approval workflows, segregation of duties, vendor verification requirements, and documented exception procedures are often better positioned to prevent a cybersecurity event from becoming a financial one.

Having controls in place is not enough. Organizations should periodically test how those controls work in day-to-day operations. A verification requirement may look effective on paper but still fail if the process does not ensure that verification is performed independently.

One of the most effective safeguards is establishing a formal process for verifying any request involving changes to banking information, ACH instructions, payment methods, or vendor records. Best practice is to confirm the request using contact information already on file rather than relying on details provided within the request itself. The FBI Internet Crime Complaint Center recommends using independent verification methods before modifying payment information.

Organizations should ensure that payment requests, approvals, and disbursements are not controlled by a single individual. Segregation of duties creates additional review points and reduces the likelihood that fraudulent changes move through the process undetected.

Exception Reviews Matter

Not every payment change presents the same level of risk. Requests involving new bank accounts, foreign financial institutions, last-minute modifications, unusual payment methods, or deviations from established procedures should automatically receive additional scrutiny.

These situations are often where fraudsters attempt to exploit urgency and bypass normal controls. Building structured exception reviews into payment workflows creates opportunities to verify information, challenge assumptions, and identify potential red flags before funds leave the organization.

The Hidden Cost of Payment Fraud

The direct financial loss associated with payment fraud is often only part of the damage. Organizations may also face project delays, vendor disputes, insurance claims, reputational concerns, increased audit scrutiny, regulatory reporting requirements, and significant time spent investigating and remediating the incident.
Finance and operational leaders may find themselves diverting resources away from strategic priorities to manage the aftermath of an avoidable event. For organizations already operating with lean accounting and finance teams, these indirect costs can quickly exceed the original financial loss itself.
This is one reason why payment fraud prevention should be viewed as a business risk management initiative rather than solely an IT concern.

Payment Fraud Is Increasingly a Cybersecurity Risk

Business Email Compromise sits at the intersection of cybersecurity and financial operations. Threat actors are no longer targeting only networks and devices. They are targeting workflow design, approval processes, and employee decision-making.
As a result, cybersecurity programs should extend beyond technical safeguards and include operational controls, employee education, governance practices, and incident response planning. The Cybersecurity and Infrastructure Security Agency recommends foundational security practices such as multifactor authentication, email security controls, and user awareness training to help reduce exposure to compromise and phishing attacks.

These measures are most effective when paired with financial controls that require independent verification before payment instructions can be modified. When cybersecurity and finance teams work together, organizations are better prepared to identify risks before they become losses.

Build a Response Plan Before You Need One

Organizations often devote significant effort to preventing fraud but considerably less attention to preparing for how they will respond if prevention measures fail. A well-designed response plan identifies key decision makers, escalation procedures, banking contacts, communication protocols, and the roles of finance, IT, risk management, and executive leadership.

The plan should also establish procedures for preserving records, investigating suspicious activity, and reporting incidents to appropriate authorities. If the incident involves tax-related identity theft, tax scams, or fake IRS communications, the IRS fraud and scam reporting guidance and broader tax scam awareness resources can help organizations understand available reporting channels.

Preparation cannot eliminate risk, but it can significantly improve an organization’s ability to respond effectively when an incident occurs.

How PBMares Can Help

Looking Ahead

The Surfside Beach incident serves as a reminder that payment fraud is not typically the result of one bad decision or one compromised email. Rather, it often occurs when cyber threats intersect with routine business processes and control weaknesses.

As organizations continue to modernize payment operations and adopt increasingly digital workflows, leaders should periodically evaluate whether their internal controls, cybersecurity practices, and vendor management procedures are keeping pace.

The goal is not to slow business down. The goal is to ensure that the processes designed to move money efficiently are also designed to protect it.
