There was a time when sending money felt like an event.
If you needed to transfer funds, you visited a bank, filled out forms, showed identification, and spoke to an actual person. Whether it was a wire transfer, cashier's check, or Western Union payment, there were multiple moments to stop and think before the money moved.
Today, it's different.
We approve invoices from our phones. Vendors update banking information by email. Payroll changes happen online. Funds move with a few clicks and a password.
The convenience is incredible. Unfortunately, it's also exactly what criminals are counting on.
What Is Wire Fraud?
At its simplest, wire fraud occurs when someone tricks your business into sending money to the wrong account through electronic means.
When the scam runs through email or other business communications, the FBI calls it business email compromise (BEC). The FBI describes BEC as a scam targeting businesses that work with suppliers or regularly make wire transfers. Criminals carry it out by compromising email accounts, phone numbers, or virtual meeting apps through social engineering or computer intrusion.
The request often appears legitimate:
- A vendor asks you to update payment information.
- An employee submits new direct deposit details.
- A supplier sends an invoice with "updated banking instructions."
- A manager receives what appears to be an urgent payment request.
The money is transferred exactly as requested.
The problem is that the account belongs to a criminal.
By the time the mistake is discovered, the funds are often long gone.
Why Small Businesses Are Prime Targets
Many business owners assume cybercriminals spend their time chasing large corporations.
In reality, small and midsize businesses (SMBs) can be especially attractive targets.
Growing organizations often operate with lean teams. They rely on trust, move quickly, and don't always have dedicated security staff or formal payment-verification procedures.
Attackers know this.
They aren't necessarily trying to break through your firewall. They're looking for weaknesses in your processes.
All it takes is one compromised email account, one convincing vendor request, or one employee who believes they're following normal procedures.
The scale of the problem is significant. According to the FBI's 2025 Internet Crime Complaint Center (IC3) Annual Report, business email compromise generated 24,768 complaints and $3,046,598,558 in reported losses in 2025. Only investment fraud accounted for more reported losses.
The Attack Usually Starts Before the Payment
Many wire fraud attacks don't begin with a fake invoice.
They begin with access.
A stolen password. A phishing email. A compromised device.
Once attackers gain access to an account, they watch. They learn who approves payments, which vendors are paid regularly, and how financial requests move through the business.
Then they wait for the right opportunity to insert themselves into a legitimate transaction.
That's what makes modern wire fraud so dangerous. It often looks exactly like normal business.
Artificial intelligence (AI) is making these scams even harder to spot. The FBI notes that AI chat tools can quickly create official-sounding emails that mimic a company's CEO, and voice cloning can be used to request wire payments. In 2025, businesses reported more than $30 million in losses to BEC scams involving AI.
Warning Signs of Wire Fraud
No single red flag proves a request is fraudulent, but these signs should prompt you to slow down and verify:
- Urgency or pressure to pay immediately, often with a warning about late fees or a lost deal.
- Changes to banking details, especially right before a payment is due.
- A sender address that's slightly off, such as a misspelled domain or a reply-to address that doesn't match the sender.
- Requests to skip normal approvals or keep a payment confidential.
- Unusual timing, such as requests that arrive after hours or while an executive is traveling.
- A change in tone or writing style from a vendor or coworker you know well.
How to Protect Your Business from Wire Fraud
Technology plays an important role, but wire fraud prevention requires more than antivirus software.
Businesses should have:
- Multi-factor authentication (MFA) on email, banking, and other critical accounts
- Email security controls that filter phishing messages and flag spoofed or lookalike senders
- Verification procedures for any change to banking or payment details
- Dual approval for wire transfers and other large payments
- Employee awareness training so staff know what to look for
- Ongoing monitoring for suspicious activity, such as unusual sign-ins or new email forwarding rules
One simple rule can help reduce the risk:
Never trust new payment instructions sent by email alone. Verify them by calling a known phone number, not one listed in the email, before sending money.
What to Do If You've Sent Money to a Fraudster
If you discover a fraudulent transfer, time is critical. The FBI recommends the following steps:
- Contact your bank immediately. Ask it to recall the funds and complete any required indemnification documents.
- File a complaint at ic3.gov, regardless of the amount lost. Include the full transaction details.
- Secure the compromised account. Reset passwords, confirm MFA is enabled, and check for unfamiliar email forwarding rules or sign-ins.
- Notify the affected vendor, customer, or partner so they can check their own systems.
Recovery isn't guaranteed, but acting quickly improves the odds. In 2025, the IC3 Recovery Asset Team's Financial Fraud Kill Chain process handled 3,900 incidents involving $1,163,919,846 in attempted theft and helped freeze $679,013,183, a 58% success rate.

Frequently Asked Questions
What is the difference between wire fraud and business email compromise?
Wire fraud is the broad term for using electronic communications to trick someone into sending money. Business email compromise is a specific type of wire fraud in which criminals compromise or impersonate business email accounts, or other communication channels, to redirect payments.
Can money lost to wire fraud be recovered?
Sometimes. Recovery depends heavily on how quickly you act. Contact your bank right away to request a recall, and file a complaint at ic3.gov with the full transaction details.
What is the best way to prevent wire fraud?
Combine technical controls, such as MFA and email security, with clear business processes. The most important habit is verifying any new or changed payment instructions by phone, using a number you already know is legitimate.
