# Wire fraud prevention for finance teams: how to stop bank wire fraud

> **Wire fraud prevention** means making sure every outgoing wire goes to the right account, for a legitimate reason, before it is released. Because bank wires settle fast and are hard to recall, the controls must act before release: verify payee details and the requester out-of-band, require dual approval above a threshold, use bank-side controls such as payment templates and Positive Pay, and keep an audit trail.

## Key takeaways

- **Bank wire fraud** against businesses is mostly social engineering: fake vendor bank changes, fake executive requests and spoofed real-estate or legal instructions.
- Wires were the payment method targeted in **25%** of fraud attempts in AFP's 2026 survey - and they are the hardest to claw back.
- The core of payment fraud protection is a written **wire release procedure**: expected payment, verified payee, verified requester, dual approval, evidence.
- Bank tools (templates, dual authorization, Positive Pay, ACH blocks) help, but they can't tell whether the person who asked was real.

## What is bank wire fraud?

Bank wire fraud is when a criminal causes a wire transfer to be sent to an account they control. For businesses, the bank's systems are rarely “hacked”; instead, someone with authority to send a wire is persuaded to do so - by a fake vendor, a fake executive, or fake instructions inserted into a real transaction. Because the wire is authorized by a genuine employee, the bank usually treats it as a valid payment.

The scale is large. The AFP's 2026 survey found 76% of organizations experienced attempted or actual payments fraud in 2025, with wires targeted in 25% of cases, and only 17% using AI for fraud mitigation. The FBI's IC3 recorded roughly $3.0 billion in business email compromise losses in 2025.

## Common wire fraud scams

| Scam | How it works | Control that stops it |
| --- | --- | --- |
| Vendor bank-change fraud | Impersonated supplier asks you to pay invoices to a new account | Callback to known vendor contact before the change; hold first payment |
| CEO / executive fraud | Fake CEO or CFO requests an urgent, confidential wire | Verify on a channel you choose; dual approval with no exceptions |
| Deepfake call or video meeting | Cloned voice or video of an executive “approves” a transfer | Challenge question or identity-bound approval; inbound calls never count |
| Real estate / closing fraud | Spoofed title company or lawyer sends changed wiring instructions before a closing | Verify instructions by phone using a number from the original engagement |
| Fake invoice for a real vendor | Altered invoice with new remittance details | Pay only to verified vendor master details |
| Account takeover | Attacker gains access to your bank portal or an approver's email | MFA, dual authorization in the bank portal, alerts on new beneficiaries |

## Why wire transfers are hard to recover

Wires are designed to be fast and final. Once funds land, fraudsters usually move them on quickly through other accounts. A recall depends on the receiving bank's cooperation and on whether the funds are still there, so recovery odds fall sharply with every hour. That is why wire fraud prevention has to focus on the moments **before** release, not on detection afterwards.

## How to prevent wire fraud: the wire release procedure

Adopt one written procedure for every outgoing wire and repetitive payment above your threshold. These steps are also the backbone of any program to prevent payment fraud by ACH or card:

1. **Confirm the payment is expected.** Match the wire to an approved invoice, contract or board-approved transaction. A wire with no underlying document does not proceed.
2. **Check the payee details against your records.** Compare beneficiary name, bank, routing/SWIFT and account number with the verified vendor master or a prior verified wire. Any difference is a change and needs change verification first.
3. **Verify the requester out-of-band.** If the wire was requested by email, chat or phone, confirm with the requester on a channel and number you already had - not one in the request. For executive requests, use a challenge question or identity-bound approval.
4. **Verify the payee for new or changed details.** Call the beneficiary's known contact and validate the account (account-ownership check or prior verified payment) before first use.
5. **Apply dual approval.** A second authorized person approves in the bank portal. The preparer cannot be the approver, and approvals happen in the bank system, not by email.
6. **Release and record.** Release using a bank template where possible. Store the request, verification evidence and approvals together.
7. **Confirm receipt.** For new payees or large amounts, confirm with the beneficiary, through known contact details, that funds arrived as expected.

> [!WARNING]
> **No exceptions for urgency**
> Urgency is the attacker's main lever. Decide in advance who can authorize an emergency wire and how it is still verified - so nobody has to make that call under pressure.

## Approval thresholds and segregation of duties

Thresholds should reflect your payment volumes and risk appetite. A sample matrix for a mid-size company - adjust the numbers to your own business:

| Payment | Verification | Approvals |
| --- | --- | --- |
| Repeat payment to a verified payee, below threshold | Match to invoice; details unchanged | Preparer + 1 approver |
| Any payment to a new or changed beneficiary | Out-of-band callback + account validation before first use | Preparer + 1 approver; controller sign-off on the change |
| Wire above $[threshold] | Requester verified out-of-band; payee confirmed | Preparer + 2 approvers, one at controller level or above |
| Executive-requested or confidential wire | Executive verified on a channel finance chose, with a challenge | CFO + controller; never the requester alone |
| International wire to a first-time beneficiary | Enhanced review of reason and beneficiary | Controller + CFO |

Keep the three key duties separate: **who can change payee details**, **who can prepare a payment**, and **who can approve it** in the bank portal. In small teams where that is hard, add an independent reviewer of the vendor master change log and bank activity.

## Bank-side payment fraud protection

- **Dual authorization in the bank portal** - a second user must approve every wire or new beneficiary.
- **Wire templates** - repetitive wires go only to pre-approved beneficiaries; free-form wires need higher approval.
- **Positive Pay** - the bank matches checks (and ACH Positive Pay, ACH debits) against what you issued or authorized, and flags exceptions for you to decide.
- **ACH debit blocks and filters** - only authorized companies can debit your accounts.
- **Payee name checks / account validation** - services that confirm the account holder name matches the intended payee before you send.
- **Alerts and limits** - notifications for new beneficiaries, large wires and changed users; per-user and daily limits.
- **Strong authentication** - hardware or app-based MFA for every portal user, and prompt removal of leavers.

These controls are valuable, but they all assume the employee who instructed the payment was right to do so. They can't tell you whether the vendor or executive behind the request was real. That gap is filled by out-of-band person verification.

## Insurance, auditors and the audit trail

Many commercial crime policies treat a transfer an employee authorized voluntarily differently from theft, and **social engineering fraud coverage** is often a separate endorsement with its own sub-limit. Some policies require that payment-instruction changes were verified by callback. Check the wording with your broker, and keep evidence of each verification - date, contact, number dialed, approvers - so you can show the control operated. Auditors will ask for the same evidence when testing controls over vendor master changes and disbursements.

## If a fraudulent wire goes out: the first hour

1. Call your bank's fraud line and ask for an immediate recall and a hold request to the receiving bank.
2. File a complaint at ic3.gov with the transaction details.
3. Lock down affected email and bank-portal accounts; reset credentials.
4. Preserve emails with headers, call logs and approval records.
5. Notify your insurer and, if relevant, the real vendor or customer whose identity was used.

## Where RealPayee fits

[RealPayee](https://realpayee.com) adds the step bank controls don't cover. A high-value wire or a changed beneficiary in NetSuite, QuickBooks, Xero, Bill.com or Ramp is held until the real vendor contact or executive verifies out-of-band - on their enrolled phone, or with ID plus a live selfie - then released or blocked with an audit record your auditors and insurer can review.

## How to release a wire transfer safely

1. **Confirm the payment is expected** - Match the wire to an approved invoice, contract or board-approved transaction. A wire with no underlying document does not proceed.
2. **Check the payee details against your records** - Compare beneficiary name, bank, routing/SWIFT and account number with the verified vendor master or a prior verified wire. Any difference is a change and needs change verification first.
3. **Verify the requester out-of-band** - If the wire was requested by email, chat or phone, confirm with the requester on a channel and number you already had - not one in the request. For executive requests, use a challenge question or identity-bound approval.
4. **Verify the payee for new or changed details** - Call the beneficiary's known contact and validate the account (account-ownership check or prior verified payment) before first use.
5. **Apply dual approval** - A second authorized person approves in the bank portal. The preparer cannot be the approver, and approvals happen in the bank system, not by email.

7. **Confirm receipt** - For new payees or large amounts, confirm with the beneficiary, through known contact details, that funds arrived as expected.

## Frequently asked questions

### What is bank wire fraud?

Bank wire fraud is when a criminal tricks someone into sending a wire transfer to an account the criminal controls - usually by impersonating a vendor, an executive or a party to a transaction.

### How can businesses prevent wire fraud?

Use a written wire release procedure: confirm the payment is expected, check payee details against verified records, verify the requester and any new payee out-of-band, require dual approval in the bank portal, and keep evidence of each step.

### How do you prevent payment fraud in accounts payable?

Verify every vendor bank-detail change with a known contact, separate the duties of changing vendors, preparing and approving payments, use bank controls such as Positive Pay and dual authorization, and review vendor master changes weekly.

### Can a wire transfer be reversed?

Sometimes, if you act very quickly. Your bank can request a recall from the receiving bank, but success depends on whether the funds are still there. Call your bank immediately and file at ic3.gov.

### Does Positive Pay stop wire fraud?

No. Positive Pay matches checks (and, with ACH Positive Pay, ACH debits) against what you authorized. It does not verify outgoing wires that your own staff instructed, which is how most business wire fraud happens.

### What is payment fraud protection?

The combination of process, bank services and tools that stop unauthorized or fraudulent payments: out-of-band verification, approval thresholds, segregation of duties, account validation, Positive Pay, monitoring and insurance.
