Vendor Impersonation Fraud

Vendor impersonation fraud is on the rise, posing a significant threat to businesses of all sizes.

According to the FBI’s Internet Crime Complaint Center, Business Email Compromise fraud, a key tactic used in vendor impersonation, accounted for $2.4 billion in losses in 2021 alone.

This fraud type typically involves cybercriminals posing as trusted vendors to deceive companies into making payments to fraudulent accounts.

With global businesses becoming increasingly interconnected, the risk of falling victim to sophisticated impersonation schemes has never been higher.

In fact, 43% of companies reported experiencing vendor email compromise in the past two years, often leading to significant financial and reputational damage.

Knowing how these financial scams operate and implementing enhanced verification processes is essential to protecting your business.

In this guide, we will explore key tactics used by fraudsters, effective prevention strategies, and how to build a fraud-resilient organisation.

Don’t let vendor impersonation fraud compromise your company’s future!

What is Vendor Impersonation Fraud?

When an impersonator pretends to be a real supplier or vendor to deceive a business into paying them or providing them with private information, this is called vendor impersonation fraud.

Fraudsters often create fake email addresses or websites that mimic those of real vendors, tricking businesses into wiring money to fraudulent accounts.

This type of fake vendor fraud can lead to significant financial losses or damage to the company’s reputation if not detected early.

The first thing fraudsters do is get information about a company’s suppliers from public sources, phishing scams, or data breaches.

Then, using small changes to email addresses or phone numbers, they make believable emails or fake invoices that look like they are from a real company.

In these fake messages, they ask for money instantly, change your banking details, or send you fake invoices. It’s hard to get the money back once it’s been sent to the fraudulent account.

With the rapid shift towards digital communication methods and the growing number of business transactions conducted online, vendor impersonation fraud has seen a sharp rise.

As companies grow their networks around the world and deal with more complicated supply chains, scammers take advantage of these weak spots by getting involved with vendor relationships.

It gets harder to spot these scams as scammers use more advanced phishing techniques and AI-generated content to look like they are real.

How Does Vendor Impersonation Fraud Work?

Vendor impersonation fraud uses a variety of complex tactics to deceive businesses into doing fraudulent transactions. This is how scammers usually work:

Email Phishing Scams

Fraudsters start by using phishing scams, sending emails that appear to come from legitimate vendors. These emails could have unusual requests for payment, notices of updated banking details, or fake invoices.

The email addresses are often slightly changed, like “vendorname. co” instead of “vendorname.com,” which makes them hard to spot at first look.

Spoofing Legitimate Vendor Accounts

Fraudsters may use a fake email address or phone number of a real vendor to make their message seem more trustworthy. This makes it look like the communication is coming from a real source. 

This creates a false sense of legitimacy, especially if the fraudsters have studied the target’s previous vendor interactions.

Fake Websites and Invoices

In some cases, cybercriminals create fake websites or online payment portals that mimic real vendors’ sites. They use these to trick businesses into entering payment details or credentials, which they then exploit.

Fake invoice fraud is also common, crafted with the right branding and details to further deceive the company. Here is the breakdown of the Fraud Process:

• Fraudsters send an email that looks like it came from a real vendor account but is actually a fake one.
• The email has urgent approval requests to change banking details or make an immediate payment.
• As soon as the business sends the payment to the fraudulent account, the money is moved, making it very hard to get it back.

In 2020, a UK energy firm lost over $240,000 after falling victim to vendor impersonation fraud, and a U.S. construction company reported a $1.5 million loss due to fake vendor payment fraud.

Common Red Flags of Vendor Impersonation Fraud

Vendor impersonation fraud can be difficult to detect, but recognising common fraud indicators can help protect your business from falling victim to this type of scam. Here are some key fraud techniques to watch for:

Inconsistent or Unusual Communication Patterns

One of the most common red flags is a sudden change in how a vendor communicates. If a vendor that typically communicates by phone suddenly starts sending urgent emails, or if the tone of their messages becomes more urgent or demanding, it’s worth investigating further.

Fraudsters often try to make people feel like they need to act quickly without verifying details.

Changes in Payment Instructions

If you receive an email or communication that involves a change in the vendor’s invoice payment instructions—such as a new vendor bank account or different payment method—this should raise immediate concern about email fraud.

To make sure about any changes, you should always contact the vendor directly using a verified phone number or email. Make sure you never use the number or email address in the suspicious communication.

Unverified Requests for Sensitive Information

Be wary of any emails requesting sensitive business information, such as account numbers, tax IDs, or banking details. Legitimate vendors don’t ask for this kind of information through email, especially without proper verification procedures.

You should double-check the request through a secure communication channel if you are quickly asked to give this information.

Suspicious Email Addresses and Domain Names

Often, fraudsters will use email addresses that are nearly identical to those of vendors’ official email accounts but with subtle differences, such as an extra letter or a slightly altered domain (e.g., “.net” instead of “.com”).

Always scrutinise the sender’s email address and domain, and if something looks off, verify the communication before taking any action.

Why Are Businesses Targeted?

Vendor impersonation fraud is a growing threat because larger companies, especially those with multiple vendor relationships, present an attractive target for cybercriminals. Here’s why:

Vendor Relationships Create Vulnerability

Businesses interact with their suppliers on a regular basis, which makes it easier for scammers to get their hands on these trusted relationships. Large organisations often work with several suppliers, which makes it hard to keep a close eye on all of their transactions.

Fraudsters take advantage of these well-established relationships by pretending to be reliable vendors and deceiving businesses into sending fraudulent requests to real accounts.

Because of this, vendor impersonation fraud is more likely to happen at larger companies, especially ones with complicated supply chains.

Lack of Stringent Verification Procedures

Many businesses fail to have robust procedures in place for verifying vendor communications, especially when it comes to financial transactions. In some cases, payments or changes to banking details are approved without a second review or cross-check.

Fraudsters capitalise on this by creating convincing fake invoices or sending urgent requests for payment changes. Without stringent protocols, such as two-factor authentication or multiple approval layers, businesses become easy targets for fraud.

Human Error and Lack of Awareness

Fraudsters rely heavily on human error, knowing that employees often overlook subtle discrepancies in emails, phone numbers, or domain names. A lack of awareness about common scams and phishing scams further enables these frauds.

Employees may unwittingly act on fake invoice requests without verifying the legitimacy of the communication, particularly if they feel pressured by time-sensitive demands.

With insufficient employee training and awareness programs, businesses remain at high risk for vendor impersonation attacks driven by human error.

Top Strategies to Prevent Vendor Impersonation Fraud

Fraud involving pretending to be a different vendor can cost a lot of money and hurt your image. Businesses can lower these risks by implementing robust strategies to protect against vendor fraud schemes.

Here are some important vendor fraud prevention measures:

Verification of Vendor Information Before Any Transactions

Verification of vendor information is an important measure to avoid becoming a victim of vendor impersonation fraud.

Businesses should reinforce a robust communication protocol to authenticate the identity of these rightful owners before authorising any financial transactions or responding to requests for changes in banking details.

This means validating the request through a secure communication channel, such as dialling a verified phone number or using an established email address. Any requests that seem unusual or urgent should raise suspicion.

Because fraudsters often create a sense of urgency to rush decision-making. By taking the time to verify details—especially in the case of large transactions or sudden changes—companies can protect themselves from transferring funds to fraudulent accounts.

Implementing a “no exceptions” policy for verification can significantly reduce the risk of falling victim to vendor impersonation scams.

Using Multi-Factor Authentication (MFA) for Financial Approvals

When Multi-Factor Authentication (MFA) is used for financial approvals, employees must verify their identity using two or more authentication methods before authorising any transaction. This makes security stronger.

This extra layer of protection helps ensure that even if a fraudster gains access to an employee’s password or email, they would still need a second form of verification, such as a mobile authentication app, SMS code, or physical security token, to complete the process.

For vendor payment approvals, MFA greatly lowers the risk of fraudulent transactions by preventing unauthorised access to sensitive financial systems. It also acts as a deterrent for cybercriminals, making it more difficult to breach accounts.

Implementing MFA is especially critical for high-value transactions or any requests involving changes to vendor payment details, offering businesses a robust defense against vendor impersonation fraud and other forms of cyber attacks.

Training Employees to Recognise Fraudulent Communications

Training employees to recognise fraudulent communications is essential in vendor fraud prevention.

Regular training sessions should focus on educating staff about the tactics used by fraudsters, such as phishing emails that appear legitimate but contain subtle discrepancies, like altered email addresses or domain names.

Employees should learn to spot red flags, like urgent requests for payment changes or private information. Also, it should be directed to check any messages that seem fishy before acting on them.

Fostering a culture of scepticism regarding unsolicited or unexpected financial requests is vital; employees should feel empowered to question and investigate these requests rather than acting impulsively.

Conducting cybersecurity training or sharing real-life case studies can enhance awareness and improve response strategies.

By equipping employees with the knowledge and confidence to recognise potential cybersecurity threats, businesses can significantly reduce their vulnerability to vendor impersonation fraud.

Implementing Secure Payment Systems

Implementing secure payment systems is vital for protecting businesses from vendor impersonation fraud. Investing in encrypted payment platforms ensures that sensitive financial information is safeguarded against attacker access.

These systems often come equipped with advanced fraud detection features that automatically flag suspicious transactions, providing an additional layer of security.

For instance, requiring verification for any changes to vendor payment details helps prevent unauthorised modifications that could lead to fraud.

Furthermore, automated systems for payment tracking enhance visibility into payment processes, enabling companies to identify irregularities or patterns that may indicate fraudulent activity.

These systems can generate alerts for management, allowing them to intervene before any funds are erroneously transferred.

By integrating secure payment systems with robust monitoring and alert mechanisms, businesses can significantly minimise their exposure to vendor impersonation fraud, protecting their financial resources and maintaining trust with legitimate vendors.

The Role of Technology in Fraud Prevention

Technology is pivotal in vendor fraud prevention, offering advanced features that enhance security measures.

AI and Machine Learning for Anomaly Detection

Artificial intelligence (AI) and machine learning (ML) have transformed how businesses detect anomalies in vendor communications. AI can identify deviations that may indicate fraudulent activity by analysing patterns in email account activity, transaction histories, and communication styles.

For instance, if a vendor suddenly changes their email address or requests a payment in a different format, the system can flag these anomalies for further investigation. This proactive approach allows organisations to respond swiftly to potential threats before they escalate.

Cybersecurity Tools to Block Phishing Attempts

Sophisticated cybersecurity tools are essential for protecting businesses against phishing attempts, a common tactic used in vendor impersonation fraud.

These tools utilise various fraud detection techniques, such as email filtering and real-time threat intelligence, to detect and block suspicious emails before they reach employees.

By scanning emails for malicious links, attachments, or spoofed sender addresses, these solutions reduce the likelihood of employees falling victim to phishing schemes.

Blockchain for Securing Vendor Transactions

Blockchain technology also plays a vital role in securing vendor transactions. By providing a decentralised and immutable ledger, blockchain ensures that all transactions are recorded transparently and securely.

This technology makes it nearly impossible for fraudsters to alter transaction records or impersonate vendors, as every transaction is verifiable and traceable.

As organisations increasingly adopt blockchain for supply chain and financial transactions, they can enhance the integrity and security of vendor relationships, significantly reducing the risk of impersonation attacks.

Creating a Vendor Verification Process

Developing a robust vendor verification process is essential for mitigating the risks associated with inadequate security protocols. Here’s a step-by-step guide to establishing an effective protocol:

Verifying Vendor Bank Details

Always verify the bank account details provided when onboarding a new vendor or changing payment details.

Contact the vendor directly using a known phone number (not one from the invoice) to confirm the banking details. This step ensures that you are not communicating with a fraudster posing as the vendor.

Setting Up Multiple Points of Contact

Establish multiple points of contact within your organisation and with the vendor. Having a secondary contact within the vendor’s company allows for additional verification of any requests, particularly for payment changes or sensitive information.

Internally, ensure that at least two employees of the finance team are involved in approving vendor payments to create a system of checks and balances.

Implementing Internal Controls for Payment Approvals

Create clear internal controls for payment approvals. Define roles and responsibilities for employees involved in the payment process, ensuring that no single individual has complete control over transactions.

Implementing dual approval processes for large payments can prevent unauthorised transactions and reduce fraud risks.

Case Studies of Vendor Impersonation Fraud

Between 2013 and 2015, Facebook and Google fell victim to an elaborate phishing campaign that resulted in a loss of $100 million. The attacker exploited the fact that both companies used Quanta, a Taiwan-based vendor, by sending a series of fraudulent invoices impersonating the supplier.

Believing the invoices were legitimate, both companies made payments. The scam was eventually uncovered, leading to the arrest and extradition of the fraudster from Lithuania. Thanks to legal proceedings, Facebook and Google recovered $49.7 million of the stolen $100 million.

FACC, an Austrian aerospace parts manufacturer, was defrauded of $61 million in 2016 when a scammer impersonating the CEO instructed an employee to transfer the funds. This incident was notable because FACC fired both the CEO and CFO for failing to implement proper security measures.

The company later sued the executives for $11 million in damages, highlighting the personal risks for leaders who neglect cybersecurity.

In 2014, Upsher-Smith Laboratories, a Minnesotan pharmaceutical company, lost $39 million to a BEC attack. The phisher, posing as the CEO, instructed an accounts payable employee to send wire transfers while an alleged “lawyer” guided the process.

The company managed to stop one transfer, reducing the loss from $50 million to $39 million, and later sued its bank for missing several red flags.

In Belgium, Crelan Bank experienced a Business Email Compromise (BEC) scam, losing approximately $75.8 million. The attackers compromised the email account of a senior executive and tricked employees into transferring funds to an account they controlled.

The email account compromise was only discovered during an internal audit, but the bank was able to absorb the financial hit due to its internal reserves.

Lastly, in 2015, Ubiquiti Networks, a US-based networking company, was defrauded of $46.7 million in a BEC scam. Over 17 days, the attackers impersonated the company’s CEO and lawyer, convincing the Chief Accounting Officer to make 14 wire transfers to accounts in various countries.

The FBI alerted Ubiquiti to the fraud, allowing the company to halt future transfers and attempt to recover some of the lost funds.

What to Do If You Become a Victim of Vendor Impersonation Fraud?

Quick action is essential to minimise damage if your business falls victim to vendor impersonation fraud. Here are the immediate and long-term steps you should take to avoid future risks:

Freeze Payments

As soon as you suspect fraud, freeze any pending payments to the fraudulent account. Contact your financial institution immediately to stop or reverse any transactions. If funds have already been transferred, the faster you act, the greater your chances of recovering the money.

Contact the Legitimate Vendor and Financial Institution

Inform the legitimate vendor about the fraud to ensure they are aware that any altered invoice payment instructions were not authorised by them. This helps prevent further miscommunication.

At the same time, notify your financial institution about the fraudulent activity so they can initiate an investigation and take measures to recover the lost funds.

Report to Authorities and Fraud Watchdogs

File a report with local law enforcement and, if necessary, federal authorities such as the FBI’s Internet Crime Complaint Center (IC3) in the US or Action Fraud in the UK.

Reporting to cybersecurity governance, such as industry-specific regulatory bodies or cybersecurity organisations, can also help track and combat vendor impersonation schemes.

Long-Term Recovery and Legal Steps

Once the immediate threats are contained, consult with legal experts to assess your options for recovery. This may include pursuing litigation against the fraudsters, your financial institution (if due diligence was not observed), or other involved parties.

Review and strengthen internal protocols, such as multi-factor authentication and vendor verification processes, to prevent future incidents. Additionally, invest in ongoing staff training to raise awareness and reduce vulnerability to fraud.

Vendor Impersonation Fraud and Its Legal Implications

Vendor impersonation fraud has significant legal implications for both the victims and perpetrators. Knowing your legal options is vital if your business falls prey to such fraud in action.

Legal Actions You Can Take as a Victim

As a victim, you have several legal avenues to explore. The first step is to work with law enforcement agencies and legal counsel to file a formal complaint. This often includes cooperating with local authorities or international agencies such as the FBI (via IC3) or Europol to investigate the fraud.

You may also have the option to pursue civil litigation to recover losses, potentially suing either the fraudsters themselves (if identified) or third parties like banks if they failed to follow proper protocols.

In some cases, your insurance policy may cover cybercrime or fraud, and filing a claim is another potential recovery route.

Laws and Regulations Surrounding Fraud Prevention

Many countries have stringent laws and regulations to combat financial fraud. In the U.S., laws like the Computer Fraud and Abuse Act (CFAA) and wire fraud statutes are applicable. The UK has the Fraud Act 2006, which provides legal recourse for victims of vendor impersonation fraud.

Globally, data protection laws such as GDPR (General Data Protection Regulation) may come into play if personal information was compromised during the scam. Knowing the applicable laws can help guide your legal response and strengthen your case against perpetrators.

Working with Authorities to Track Down Perpetrators

Authorities, including local law enforcement, financial institutions, and cybersecurity experts, play a critical role in tracking down fraudsters. They can use forensic techniques to trace email addresses, IP addresses, and financial transactions to identify perpetrators.

Working closely with these agencies ensures a coordinated effort to pursue the fraudsters and recover stolen funds.

What’s Next?

Vendor impersonation fraud is a growing threat in today’s business, but with the right preventive measures, companies can protect themselves from significant financial losses.

Businesses can reduce their vulnerability by implementing robust vendor verification processes, utilising multi-factor authentication, training employees to recognise fraud, and investing in secure payment systems.

Additionally, working closely with law enforcement and knowing the legal implications can aid in recovery if fraud occurs. Staying vigilant and proactive is essential to safeguarding your organisation against this type of sophisticated cybercrime.
