Wire Fraud

In a Nutshell

Wire fraud is a form of financial fraud committed using electronic communications. Here’s everything you need to know, including common tactics, penalties, and how to keep yourself safe. We’ll also run down a couple of high-profile examples of real-world wire fraud cases, to give you a better picture of what to look for.

Wire Fraud: How This White-Collar Crime Swindles Merchants, Banks, & Consumers

The gradual increase in electronic transaction volume is leading to a commensurate rise in fraud.

Scammers are well-aware that electronic transfers are the payment method of choice for high-value transactions. They’re exploiting vulnerabilities in payment rails to trick individuals and companies into transferring funds to unintended recipients.

How much of a problem is this?

Well, in 2022, the Internet Crime Complaint Center (IC3) received 21,832 complaints, with losses totaling over $2.7 billion, resulting from just one specific wire fraud tactic (business email compromise). Victims are also being targeted with tactics like spoofing, social engineering, and phishing, resulting in many billions more in losses.

To make matters worse, the financial losses are just the tip of the iceberg. Merchants who fall victim to (or otherwise fail to prevent) wire fraud may also lose customers, tarnish their reputations, or even face possible regulatory penalties.

In this article, I’ll discuss wire fraud and describe how scammers carry it out. I’ll also talk about why businesses fall victim to wire fraud and what you can do to protect yourself.

What is Wire Fraud?

Wire Fraud

[noun]/wī • ər • frôd/

Wire fraud is a type of financial fraud where scammers use electronic communication, such as emails, phone calls, or the internet, to trick victims into initiating domestic or international wire transfers to unintended recipients. Fraudsters use cybercrime techniques like phishing, ransomware, identity theft, social engineering, and business email compromise scams to carry out wire fraud attacks.

Wire fraud is a pretty broad topic.

It covers any fraud involving the use of telecommunications or the internet. That means any fraud scheme carried out through email, phone calls, text messages, or online communications will qualify. The goal is to trick victims into wiring funds to accounts controlled by criminals.

It’s hard to trace and recover stolen funds because wire fraud operates across digital and financial networks. Scammers use sophisticated tactics, from spoofing emails to creating fake websites or hacking into legitimate accounts to appear credible.

Wire fraud is a federal crime in the US, carrying penalties including fines and imprisonment. But, the promise of a big payoff is enough for lots of scammers (and their accomplices) to take the risk.

Elements of Wire Fraud

TL;DR

Wire fraud occurs when a person intentionally devises a scheme to deceive someone for financial or material gain using interstate electronic communications such as emails, phone calls, or websites. To secure a conviction, prosecutors must prove the defendant acted dishonestly with intent to defraud and that the scheme involved and used interstate communications.

Wire fraud can cover a lot of different behaviors. So, what exactly counts?

Section 941 of the Criminal Resources Manual, part of the Department of Justice's internal Justice Manual, cites 18 U.S.C. § 1343 (2008) in putting together a four-element definition of wire fraud. Prosecutors must prove all four are present in order to secure a conviction for the crime:

  • That the defendant voluntarily and intentionally devised or participated in a scheme to defraud another out of money
  • That the defendant did so with the intent to defraud
  • That it was reasonably foreseeable that interstate wire communications would be used
  • That interstate wire communications were in fact used

In layman’s terms, an individual commits wire transfer fraud only when they deliberately acted dishonestly with the goal to deceive others. And, in fact, they made false promises, lies, or hid critical information to trick a victim out of money, property, or something else of value.

In addition, the individual must have expected to involve, and have actually involved, interstate electronic communications — such phone calls, emails, social media messages, or websites — when carrying out the fraud. A scheme that does not cross state boundaries would not be a federal offense.

Important!

That “interstate wire communications” clause is especially relevant when it comes to chargeback abuse. If a buyer deliberately engages in cyber shoplifting, it could be classed as a form of wire fraud, because it was conducted via interstate electronic communications.

Common Wire Fraud Tactics

Although fraud tactics are commonly evolving and may be difficult to anticipate, you can be on high alert for several common and “evergreen” tactics. These include:

Business Email Compromise

In a business email compromise scam, a fraudster hacks into a company’s email system, impersonates a trusted authority within the company, and then sends out a wire transfer request to staff. A sophisticated fraudster may not strike immediately; to avoid detection, they will monitor the style of communication in company emails for some time before penning a request for funds. This tactic can ensnare even the longest-tenured and most fraud-aware members of an organization.

Vendor Impersonation

This technique occurs when a fraudster impersonates a legitimate vendor or supplier, and then uses the faked identity to send an invoice or request a payment from the client via wire transfer. To make the scam believable, the criminal may issue new wire instructions, citing problems with their previous bank account. If the client fails to verify these new banking details, they will assume the request is genuine and may initiate a wire transfer.

Overpayment Scams

Here, a fraudster makes a purchase and pays using a check whose amount intentionally exceeds the cost of the product or service received. The fraudster, citing an “accidental” overpayment, asks the recipient to refund the difference via wire transfer. Of course, the check was fake all along, and the recipient ends up losing both the merchandise sold and money wired.

Insider Fraud

In insider fraud, an employee with legitimate access to an organization’s sensitive information co-opts them for fraudulent purposes. For example, an employee may siphon company funds to a private account, exaggerate expenses, create bogus invoices, initiate wire transfers to themselves, or impersonate the accounting or finance team and request that a client remit payments to a personal account.

Phishing

A fraudster sends you a fake email or SMS that downloads and installs malware on your device. Or, a phishing link may also direct you to a phony site that asks you to fill out your personal information. Either way, the fraudster obtains your personally identifying information, such as your name, date of birth, social security number, or banking information, which they use to conduct wire transfers on their own.

Penalties for Wire Fraud

A defendant convicted of wire fraud under 18 U.S.C. § 1343 (2008) commits a federal offense that carries a maximum fine of $250,000 per violation and/or a prison sentence of up to 20 years.

If the defendant is an organization, rather than an individual, the maximum fine is doubled to $500,000 per offense. Courts may also order that the fraudster pay restitution to the victim, and/or forfeit the assets they gained illegally through the crime.

§ 2B1.1 of the Federal Sentencing Guidelines, a set of non-binding rules created by the United States Sentencing Commission (USSC), establishes more granular sentencing recommendations for offenders. A number of factors can be used to determine an exact sentence, including (but not limited to):

  • The fraudster’s previous criminal record
  • The loss involved
  • The violations concurrently committed
  • The victim of the crime

Notable Examples of Wire Fraud

Let’s be honest here: a lot of perpetrators of wire fraud will never face justice.

They might make it out with thousands — or even millions — in stolen proceeds. But, we do have some high-profile examples of scammers that got caught that we can point to.

The Tom Girardi Fraud Case

The Tom Girardi Fraud Case

In August 2024, 85-year-old Tom Girardi, a former attorney and name partner of the now-defunct Girardi Keese, a Los Angeles-based law firm, was found guilty of four counts of wire fraud and embezzlement involving his clients’ settlement funds. During the trial, Girardi was revealed to have used $15 million worth of client funds to pay for personal expenses, including private jets and luxury cars. He also used the stolen money to fund his estranged wife Erika Jayne’s entertainment business.

His former chief financial officer, 51-year-old Christopher Kazuo Kamon, was also convicted of two counts of wire fraud. In his plea, Kamon stated that over a 10-year period spanning between 2010 and December 2020, he worked with Girardi to embezzle funds worth millions of dollars from the law firm’s hapless clients.

Kamon also admitted to embezzling the law firm’s funds for personal use. He managed to pull this off by working with co-conspirators who posed as vendors that sent fraudulent invoices to the firm for bogus goods and services.

The Arizona Couple Medical Scheme

39-year-old Alexandra Gehrke and her husband, 46-year-old Jeffrey King, ran a health care fraud scheme between November 2022 and May 2024 in Phoenix, Arizona.

Through their two sham companies, Apex Medical LLC and Viking Medical Consultants LLC, the couple used unqualified medical sales representatives to identify and administer unnecessary wound care on elderly patients.

Specifically, Gehrke instructed their representatives to order large amniotic wound grafts from specific distributors, even if the patients’ wounds did not necessitate such sizable grafts. Once the grafts were ordered, Gehrke would refer these patients to King’s company, who contracted with nurse practitioners to perform the grafting procedures. King instructed the providers to “suspend their own medical judgment and apply all grafts ordered by the sales representatives, even when medically unreasonable and unnecessary.”

During the trial, it was revealed that the graft distributors had paid Gehrke over $279 million in illegal kickbacks for the orders. The couple collectively submitted an additional $1.2 billion in reimbursement claims to federal and commercial health insurance programs for the grafting procedures.

In October 2024, Gehrke pleaded guilty to health care fraud and wire fraud. She agreed to pay $614 million in restitution and is facing a maximum prison sentence of 20 years.

King pleaded guilty to similar charges on January 31, 2025. He was ordered to pay $605 million in restitution and is likewise facing 20 years in federal prison. The couple also agreed to forfeit an additional $410 million in funds they fraudulently and jointly obtained.

The Florida “Mother Teresa” Case

Archived website: Mother Teresa Ponzi Scheme
Internet Archive. The site was shut down by court order.

41-year-old Johanna Garcia, known within her Florida community as “Mother Teresa,” pleaded guilty to running a $200 million Ponzi scheme between October 2020 and August 2021.

Garcia acquired the moniker “Mother Teresa” because her merchant cash advance business, MJ Capital Funding, purportedly generated annualized returns as high as 120% for investors.

No merchant cash advance service could sustainably support such spectacular returns without assuming significant credit risk, though. And, the company eventually made several bad loans that went unpaid.

To keep up the charade, Garcia’s business devolved into a Ponzi scheme in which she would use funds from new investors to cash out existing investors. She also siphoned off millions of dollars in profits, which she used to purchase luxury vehicles and luxury apparel.

The FBI and US Securities and Exchange Commission eventually caught wind of the operation and shut down MJ Capital Funding in 2021, but not before investors lost more than $90 million. Garcia, showing little remorse, quickly established a new fraudulent operation under a different name. 

In December 2024, Garcia was handed a 20-year sentence in federal prison for one count of conspiracy to commit mail fraud and wire fraud.

How Do You Fall Victim to Wire Fraud?

Lack of awareness of fraud tactics, inadequate or nonexistent fraud detection measures, and weak internal control systems are some of the most common reasons businesses and individuals fall victim to wire fraud.

Lack of Awareness About Wire Fraud Tactics

As mentioned earlier, fraudsters use spoofing, social engineering, or phishing techniques to trick victims into sending payments.

These tactics are sophisticated, and are constantly being innovated upon in response to new technologies and antifraud practices. Victims are more likely to fall for these tactics when they are unaware of them and do not know what channels to use to report wire fraud.

Poor Fraud Detection And Prevention Strategies

Some merchants fail to encrypt or tokenize sensitive financial information during storage or transmission. Others lack the right fraud prevention tools and systems, making it easier for fraudsters to hack into their systems, steal sensitive data, and commit fraud while flying under the radar.

Businesses that do not double-check recipient account details before initiating wires are also more susceptible to fraud than counterparts who have established procedures and checklists for accountants for finance staff to follow.

Important!

Always verify written wire instructions directly with the recipient, and be wary of common wire fraud red flags. These include last-minute changes to wire instructions, calls or emails urgently asking for transfers, high-value or unexpected transfer requests, or spelling errors and unusual phrases (e.g. “Hello Dear Sir/Madam,” “kindly,” etc.) contained within written instructions.

Additionally, don’t take the instructions you are given at face value. Instead, call the recipient yourself to confirm payment details. Do not accept incoming calls; those could be spoofed.

Weak Internal Controls

Merchants who fail to regularly monitor transactions or conduct regular audits are more vulnerable to wire fraud than organizations that subject transactions to regular review.

On this note, task segregation is important: when a single employee is in charge of sending, recording, and reconciling transactions, that individual can easily fail to notice a fraudulent transaction or, worse still, carry out fraud for personal gain. The opposite extreme is also true: the risk of internal fraud or unauthorized wire transfers can increase if too many employees can authorize payments or access sensitive information.

How to Identify & Prevent Wire Fraud Attacks

You have to educate yourself on the latest wire fraud tactics and implement the right preventative measures to counter them. This is the only way to mitigate fraud threats and block wire fraud attacks before they cause significant harm.

I recommend that you:

Tip

Use Automated Fraud Detection Tools

Sometimes, fraudsters may use sophisticated fraud tactics that can con even the most risk-aware individuals. You need multiple sets of eyes on the problem — both human and machine.

Combining fraud training initiatives for staff with automated fraud detection tools that use rules-based or machine learning techniques to identify anomalies can provide you with an extra line of defense against wire fraud.

Tip

Double-Check Transfer Details

Fraudsters will often attempt to withdraw funds obtained through wire fraud immediately, which makes recovering stolen funds difficult or even impossible. If you receive new details for a transfer, take your time to confirm the recipient’s identity and their bank account details.

When verifying details, communicate directly with the intended recipient using secure and encrypted messaging services. Don’t rely on email or instructions that were sent to you; always reach out to them to double-check.

In any case, refuse to immediately send funds, even if the fraudster pressures you to act. After all, urgency is a common fraud tactic, and you should be suspicious of any high-pressure pleas.

Tip

Enhance Fraud Prevention Measures

Enable multi-factor authentication to prevent unauthorized individuals from accessing your accounts. This ensures that even if a fraudster has your login details, they won’t be able to access your account without additional verification.

Additionally, use machine learning and AI to monitor all transactions, and detect and flag unusual transaction patterns. Redundancy is key here; the more mechanisms you have in place to detect fraudulent activity, the better your chances of intercepting an attacker.

Tip

Strengthen Internal Controls

Conduct regular audits so that you know how effective your prevention strategies are, and to confirm that all funds are accounted for.

Before sending high-value transactions, make sure there are at least two or more individuals sign off on the transaction. Delegate duties so that no employee is single-handedly responsible for the entire transaction cycle, and encourage your staff to use encrypted file transfer systems when sharing sensitive customer information in order to reduce the risk of data breaches.

Also, limit the number of employees or departments who have the authority to process wire transfers so as to minimize the risk of insider fraud.
