Article summary: A single fraudulent wire transfer can drain tens of thousands of dollars from a small business in minutes, and most of these scams start with a convincing email rather than a hacked bank account. Two-factor authentication for wire transfers adds a verification step that a scammer cannot fake with a spoofed email address alone. Layering that step onto every payment change and high-value request closes off the exact method criminals rely on most.
An urgent email arrives from the CEO asking the finance team to wire funds to a new account before the end of the day. The name is right, the tone sounds familiar, and the request seems plausible. The problem is that the CEO never sent it.
These scams do not necessarily require malware or access to the company’s network. A convincing message sent at the right moment can be enough to trick an employee into authorizing a fraudulent payment. Requiring an independent verification step before money moves can stop the scam before the business takes a loss.
Business email compromise, or BEC, relies on impersonation and social engineering to make a fraudulent request appear legitimate. In some cases, criminals spoof a familiar email address. In others, they gain access to a real business email account.
The FBI warns that these messages may appear to come from a trusted source, such as an executive, vendor, or title company, and often involve requests to send money or change payment information.
Federal Reserve Financial Services identifies business email compromise as a leading cause of fraudulent ACH and wire transfers from business accounts, highlighting how effectively criminals can use impersonation and social engineering to redirect legitimate payments.
Attackers are also increasingly targeting existing vendor relationships. One security study found that vendor email compromise attacks increased 66% during the first half of 2024, with criminals exploiting trusted business relationships to make fraudulent requests more convincing.
Protecting wire transfers requires more than securing access to online banking. Businesses also need an independent verification step before money is sent or payment instructions are changed. The key is knowing where to build those checks into the payment process.
Any email requesting a change to a vendor's or employee's payment information should be treated as unverified until confirmed by phone using a trusted number already on file, not contact information provided in the request.
This simple step can stop many payment scams because it verifies the request through a separate channel before any money changes hands.
Set a reasonable threshold above which every wire transfer requires approval from a second employee who was not involved in the original request.
The threshold does not need to be high to be useful. Even a rule requiring a second set of eyes on anything over a few thousand dollars catches most of the fraudulent requests criminals attempt against a small business.
Urgency and secrecy are common tactics used to pressure employees into acting before they can verify a request. If an executive asks for an immediate payment but cannot be reached through a trusted channel, verify the request before moving any money.
Banking portals, accounting software, and payroll systems should use phishing-resistant multi-factor authentication whenever available. Stronger authentication helps protect these accounts even if an employee’s password is compromised.
Technology alone cannot stop BEC scams. Phishing-resistant authentication can protect financial accounts from unauthorized access, but an attacker does not need to log in if an employee can be convinced to authorize the payment.
That makes employee training and clear verification procedures just as important. Finance staff and other employees who handle payment requests should know to pause and independently verify unusual or urgent instructions, even when they appear to come from an executive or trusted vendor. Regular refreshers can reinforce these habits as AI-generated emails and voice cloning make impersonation attempts more convincing.
Document the verification process as well. Maintain trusted phone numbers for vendors, banks, and executives outside of email so employees always have a reliable way to confirm a request before sending money.
Combining stronger authentication with independent payment verification addresses both sides of the risk: attackers trying to access financial accounts and those trying to persuade employees to move the money for them.
Taking a few extra minutes to verify a payment is a small inconvenience compared with trying to recover money after a fraudulent transfer.
Requiring a second approval, independently confirming payment instructions, and training employees to recognize high-pressure requests can stop BEC scams before money leaves the business.

Two-factor verification requires a payment request to be confirmed through a second, independent method before a wire transfer is approved. This might include calling a trusted number or requiring approval from another employee rather than relying on an email alone.
Wire transfers can be difficult to recover once the money reaches a fraudulent account, making them an attractive target for business email compromise and other payment scams.
Contact the requester using a trusted phone number already on file, not one provided in the email or payment request. Urgency, secrecy, or unexpected changes to payment instructions should be treated as reasons to verify the request more carefully, not skip established procedures.
