The Types of Call Center Frauds to Fight in 2026

Last updated on April 16, 2026

As the internet becomes filled with online attackers coming up with new methods each year, call centers are always in danger of fraud.

In fact, 90% of financial service contact centers see fraud attacks increasing yearly. This threat includes all industries, from financial services, to governmental institutions, airlines, and many more.

Moreover, it is agreed that contact centers are commonly attacked as they are seen as an easy target.

Your call center could be at risk right now and you might not even know it. Therefore, in this article, we will learn more about the types of common call center fraud and discuss the solutions you can use to recognize and respond to issues effectively.

The Most Common Types of Call Center Fraud

There are many types of cyber-attacks, with new ones you might never have heard of emerging each year. Here are some common contact center attacks that occur frequently.

ID Theft

ID theft is one of the most common types of contact center attacks. Fraudsters can gain unauthorized access to sensitive information in several ways: by intercepting data over public or poorly secured WiFi networks, stealing mobile devices, exploiting data breaches, or even obtaining information that users inadvertently share. Information is often shared intentionally when users are tricked by social engineering tactics, such as clicking on malicious links.

Online attackers often contact customer service centers, attempting to manipulate staff with false information. These hackers are skilled at making their messages appear legitimate, luring employees into traps.
Preventing ID theft can be achieved through a series of identity verification steps, employee training, and regular monitoring of contact center activities. The most important part is to stay vigilant of fraudulent behaviors and maintain strong security protocols.

More importantly, you need to train your staff to be prepared. Many contact center agents struggle to detect ID theft because of online attackers getting a hold of accurate customer information and therefore presenting as a legitimate customer.

Account Hijacks

After ID theft, account takeover fraud is another common method scammers use to take control of a user’s information and achieve monetary gains. Many times, they will try to manipulate contact centers by changing a user’s login data, PIN number, and other important contact details.

In order to prepare for these types of attacks, online attackers will read more about their victim’s personal information, such as where they live, when they were born, their maiden name, and more. This allows them to bypass weak knowledge-based authentication (KBA) systems.

Credit Card Fraud

This happens when a fraudster gains access to someone’s credit card. When the card is stolen, they’ll start making unauthorized transactions, purchasing items that don’t belong to them and even subscribing to different pages. This can cause significant financial losses, and the worst part is that nobody knows that someone else is using the card.

What Are The Impacts of Call Center Fraud on Businesses?

Without effective prevention strategies, call center fraud can have significant consequences for businesses, including:

Financial Losses

Unauthorized transactions and stolen funds can cause substantial financial losses for your business, and it’s not just the direct costs that you have to face; fraud detection and recovery efforts add to the financial damage.

Reputational Damage

If your call center is compromised, attackers can directly target customers by stealing their data, which can then be used to commit fraud against them too. This harms their trust in your business, potentially damaging your company’s reputation. You may also receive negative publicity from fraud incidents, which can further erode public confidence.

Operational Disruption

Fraudulent activities put a lot of stress on call center resources, making agents work harder and less efficiently due to time spent investigating suspicious calls and handling disputes. This could lower your business’s overall productivity and make it harder for you to serve real customers.

Compliance Risks

Fraud is a growing threat to compliance too, as your contact center being hacked can result in data breaches or mishandling of customer information that violate regulatory requirements, such as those demanded by HIPAA or the GDPR. This can lead to fines and legal challenges, especially if you operate in a heavily-regulated industry.

How to Detect Call Center Fraud

How can your agents detect fraud attempts early in order to help minimize their impact? Looking out for the following warning signs is the first step.

Repeated failed authentication attempts: This can indicate that fraudsters are testing stolen credentials and trying to bypass security.
High call volumes from specific numbers: Unusually high traffic from specific sources can indicate a coordinated attack. You may notice spoofed caller IDs (when a caller deliberately falsifies the information that appears on your phone’s caller ID display) that aim to obscure the fraudster’s true origin.
Spoofed caller IDs: These are calls that appear to come from trusted numbers but actually originate from fraudulent sources. For example, the number may appear as a local number despite being routed internationally or show repeated calls from identical or slightly varied numbers that mimic legitimate ones.
Unusual account activity: Look out for unexplained changes in account settings or transactions. Other suspicious customer interactions may include requests to change account details or transfer funds immediately after a call.
Caller behavior discrepancies: Fraudsters using social engineering may rely on partial or stolen information, which can lead to inconsistencies during the interaction. For example, they may provide conflicting details and struggle to answer follow-up verification questions. They may also attempt to rush or pressure the agent into bypassing standard security steps. These behavioral cues can indicate the caller does not have full, legitimate access to the account.

Fraud Prevention Strategies for Contact Centers

While fraudulent methods constantly evolve, there are still strategies and tools to help you stay vigilant and prevent breaches:

Use Fraud Detection Software

Fraud detection software is becoming increasingly important for call centers to identify potential fraud. Each software may differ from each other slightly, but in general, they all have the same goal and that is to prevent online attackers from getting into your database.

The software uses real-time monitoring and predictive analytics, including Machine Learning (ML), to assign a fraud risk score to suspicious activities. The higher the score, the more the user will be flagged. This is especially useful for detecting ID theft, which can be difficult for call center agents to spot when attackers have accurate customer information.

Fraud detection software can either be in an open-source or proprietary version. Key features in fraud detection software include:

Customer Relationship Management Integration
Password and Access Management
Multi-user Capabilities
Application Programming Interfaces (API)
Two-factor Authentications
Customer Database Management
Calendar Management
Data Visualization
Data Import and Export

Fraud data analytics can use either statistical analysis or artificial intelligence (AI). There are also four key components in a fraud prevention and detection process:

Capturing and unifying data types from all channels and incorporating them into the analytical process.
Always monitoring transactions and employing behavioral analytics for facilitating real-time decision-making.
Incorporating an analytical culture into your business through data visualization.
Employing layered security measures and authentication solutions.

In short, it’s important to have this software as it can keep an eye out for threats, even when you least expect them.

Train Your Employees

Let’s face it, you can’t be the only one in the company to know how to prevent fraud attacks. Therefore, it’s essential to teach your team how to do so as well. Training your team helps them be aware of certain behaviors that may indicate fraud and stay vigilant on upcoming attacks.

Training has to include identifying fraudulent calls and impersonation, what actions to take when your team sees suspicious activities, and making sure they know which questions they can answer and which they can’t.

Use Multi-Factor Authentication (MFA) Methods

As new technologies emerge over time, it’s becoming crucial to overcome manipulations made on the web. Multi-factor authentications (MFAs) are great since they require a user to provide more than one method of proof to access certain information.

MFAs can include using one-time passwords (OTPs), questions only you can answer, voice recognition, and many other unique features that can’t be stolen by anyone else. Overall, MFA is rising in popularity and predictions claim that by 2025, its market share will reach around $20 billion.

Leverage Biometric Technology

While many organizations embrace MFA, implementing biometric technology, especially voice recognition, is even more effective. You can’t simply steal someone’s voice. Although it’s technically possible, doing so requires tricking the voice-recognition system and having a large amount of the person’s voice data. Fraudsters in the future might find a way to make this easier, but for now, it’s a strong layer of protection.

Companies have to implement customer identification techniques and fraud prevention measures across all of their communication channels, including mobile apps, contact centers, web self-service and more.

For example, if a caller fails the voice verification test, the contact center typically won’t refuse service, as this could upset many customers. Instead, the center can perform additional biometric and non-biometric checks to verify the caller, helping to reduce the risk of fraud while still maintaining a positive customer experience.

Verify Caller Identity

Asking questions might seem contrary regarding a call center’s objective, but following a few strategic inquiries can help you fight call center fraud. The key is to understand what type of security questions you need to ask.

A fraudster won’t be able to give answers to all of the following questions:

What is your account number?
What is your reference number?
Please, give me the contract number you have on file.
Write down your telephone number.
What is your name?
List your date of birth.
Do you have any other contact telephone numbers?
What is your partial address?
What is your postcode?

The caller’s identity can be identified much easier when you ask all of these questions. In most cases, the fraudster won’t be able to answer all of them despite trying to impersonate legitimate customers. They will rarely have all of this information available to them, so this is a great way to verify caller identity.

If you find it difficult to do so, you can get the help of fraud detection teams. If you are using fraud detection software, you can automatically include these questions for your team members to know. Some popular tools you can consider using are:

SEON
CybeReady
ArkOwl
Fcase
FraudHunt
FraudLabs Pro

Additionally, some call center software has the option for using one-time passwords for an extra security layer when clients are seeking to reset their account credentials.

Set Restrictions on Your Internal Team

Statistics show that 75% of employees have stolen from their employer at least once in their lifetime.

Unfortunately, this is why many organizations fail to recognize who committed fraud. Internal fraud is the worst since internal team members can act like it came from an external source. A solution to this is to implement role-specific permissions to limit employee access to need-to-know parts of your business.

Only employees who strictly need access to customer information for organizational purposes should be granted it. Otherwise, there is no need for them to know about it.

Your Preparation Matters

It’s important that you put all the steps we mentioned into practice. Having software that always monitors suspicious activities and prevents fraud is great to have. Moreover, training your staff members is important too, since you can’t be the only one to detect fraudulent activities.

Proactive measures like MFA, document verification processes, voice recognition technologies, and setting restrictions on employees are all part of the process too. All practices play their own part in preventing fraud, and when you include all of them, you are making your life much easier.

As online attackers continuously come up with new methods to attack your organization, you need to be more prepared than you have ever been.
