Fraudsters are Exploiting Your Agents - Here’s How to Fight Back

Written by Sycurio | April 17, 2025

Contact centers are high-risk attack fraud locations that enterprises can no longer afford to overlook. While the $190 billion cybersecurity industry is focused on technical/syntactic threats, yet semantic threats, such as online scams, are ranked the second most common fraud vector in the U.S.

More often than not, call center agents unknowingly verify fraudsters, authorize scams, and innocently assist the caller in data breaches. Not because they’re negligent but because they’re human (a vulnerability no encryption protocol can fully mitigate).

While the KPIs of most customer experience or customer service leaders are measured by speed and customer satisfaction delivered by their teams, fraudsters exploit these KPIs against you:

  • The faster your agents resolve issues, the easier they are to manipulate.
  • The more they de-escalate complaints, the more susceptible they become to urgency-based deception.
  • The more frictionless your customer payment flows are, the harder it is to catch bad social engineering tactics before it’s too late.

If you add too many security layers, your CX suffers—agents slow down, operational costs increase, and customers get frustrated. If we loosen security for speed? Fraud increases, financial losses mount, and compliance risks escalate.

So, how do large enterprises secure their contact centers without compromising service quality?

Let’s find out.

What is Call Center Fraud?

Call center fraud refers to malicious activities when criminals use contact centers to steal money, customer data, or sensitive business information by tricking agents and bypassing security controls. 

Fraudsters use social engineering, account takeovers, and call spoofing to manipulate agents into giving unauthorized access to valuable accounts or systems. These attacks cause more than just financial loss because they damage customer trust, hurt company reputation, and can trigger penalties that disrupt normal business operations. Contact centers process vast amounts of private information every day, making them prime targets for criminals who look for weaknesses in procedures or technology. 

When you recognize the common methods of call center fraud, you can take better steps to protect your business and invest in stronger security measures that stop attackers before they cause harm.

Why does call center fraud happen?

In 2024, almost 29% of adults in the U.S., roughly 77 million people, faced an account takeover, making it one of the most frequent forms of identity fraud in the country, according to Security.org. Increasingly, fraudsters use contact centers to carry out these attacks by exploiting weak authentication processes to gain entry. 

The following list explains some of the leading causes behind fraud targeting contact centers.

  • Human element vulnerability: Agents work under pressure and can be deceived. Scammers often use emotional manipulation to fool agents into disclosing personal or account information.
  • Weak security measures: Many contact centers rely on outdated controls like security questions or caller ID that fraudsters easily bypass. Only a few organizations deploy layered, channel-wide identity checks to protect all customer touchpoints. Smartnumbers reports that over 90% of firms see fraud threats across voice channels like IVR and chat.
  • Speed-over-security culture: Agents rush to resolve cases and sometimes skip authentication steps to stick to response targets, creating security vulnerabilities.
  • Fraud becomes more complex: Scammers now use AI and deepfake voice tools, which makes it much harder to spot real threats. Fraud evolves fast and requires modern detection systems that move just as quickly.

Types of Call Center Fraud

You need to understand the different ways attackers use contact centers to detect and prevent fraud early. These methods often focus on weak points in agent verification steps or outdated systems that lack proper access controls:

Unauthorized account access and control:

Fraudsters often impersonate legitimate customers and use personal data to bypass verification steps. Once they get in, they can reset passwords, change account details, and lock out the real customer within minutes.

Compromise of payment card credentials:

Some attackers call in pretending to verify charges or update billing info, only to trick agents into revealing or updating card details. They may then use this information to make unauthorized purchases or resell the data on the dark web.

Both tactics rely heavily on stolen data from previous breaches or phishing attempts, and their frequency continues to increase each year. Recent reports reveal that contact center fraud surged by 60% during the last two years, showing a sharp rise in attacks. Hiya also reported that the total number of fraudulent and nuisance calls climbed from 11.3 billion in the fourth quarter of 2024 to 12.5 billion in Q1 2025.

These numbers show how quickly attackers shift their methods and how important it is to upgrade security controls before the damage spreads further.

How modern fraudsters exploit contact centers at scale

Scam networks run like corporations. It’s harder now because you aren’t against lone cybercriminals but industrialized crime engines.

Some ways in which they carry out their activities include:

    • Masking device identity: Fraudsters spoof caller IDs and locations, making their calls appear legitimate, evading basic location-based security checks and gaining trust from call center agents.
    • Account preprocessing: Fraudsters cultivate legitimate-seeming accounts by observing and mimicking real user behavior over time, bypassing traditional fraud detection systems.
    • Testing credentials for viability: Fraudsters rapidly test brute-force stolen data using AI and bots to identify exploitable accounts and catalog successful logins for future targeted attacks on contact centers.
    • Creating synthetic identities: By combining real and fabricated data, criminals create fake identities that easily pass basic verification checks and often slip under the radar for a long time.
    • Impersonating with AI voices: AI-driven voice manipulation allows fraudsters to convincingly mimic legitimate customers, even evading voice authentication systems with deepfake technology.
  • SIM swap fraud: Fraudsters trick telecom providers into transferring a victim’s phone number to a new SIM card, allowing them to control sensitive accounts linked to the victim's phone number.
  • Manipulating agent empathy: Armed with detailed personal information, fraudsters exploit agents' desire to help, bypassing authentication protocols by creating urgent or sympathetic scenarios.

Consequences of Call Center Fraud

When fraud hits your contact center, it causes lost revenue, erodes customer trust, and creates ongoing difficulties for your business. Here are the main impacts of allowing fraud to go unaddressed in your contact center operations:

Financial repercussions and asset depletion

Contact center fraud can drain your budget quickly when criminals access accounts or card details without permission. Companies now face hundreds of thousands of dollars in losses per incident. 

For instance, Regula found that financial services firms lost over $603,000 on average in 2024 due to deepfake and AI-driven fraud attacks, and roughly 10% of companies lost more than $1 million in a single event. 

Erosion of brand equity and stakeholder confidence

When consumers feel unsafe reaching your brand, trust vanishes quickly. Across fraud types, more than 90% of companies reported financial loss due to deepfakes, which shakes confidence in your brand and relationship with customers. 

As a result, customers, investors, and partners start asking tough questions, and regaining trust takes months or years.

Operational disruption and rising support costs

Fraud also digs into daily operations, triggering high volumes of calls, account freezes, and extra audits. Fraudsters now launch attacks every 46 seconds, with deepfake attempts rising more than 1300% in one year alone. 

These attacks force teams to react constantly to threats, reducing the time available for helping genuine customers. The increased workload drives up operational costs and strains support staff, making it harder to keep service levels high. Without adequate fraud controls, organizations face ongoing disruptions that slow business growth and reduce customer satisfaction.

Regulatory and legal risk

When consumers lose money and report fraud more often, regulatory agencies respond by tightening rules and increasing penalties to protect the public. In 2024, the Federal Trade Commission recorded consumer losses totaling $12.5 billion from all types of fraud, which pushed regulators to step up audits and enforcement actions across many industries.

Companies that lack strong fraud protections face heavy fines, expensive legal fees, and mandatory reporting that drain resources and distract leadership from focusing on core business goals. Organizations that delay meeting compliance requirements risk permanent damage to customer trust and could face costly lawsuits that threaten their long-term operations.

Essential Best Practices to Prevent Call Center Fraud

Preventing call center fraud requires a clear plan that targets common weaknesses and protects customer interactions. By using specific strategies, companies can reduce risks and stop scammers from taking advantage of system gaps. 

Here are several effective methods to apply:

Alter outgoing IVR messages

Regularly updating and randomizing Interactive Voice Response (IVR) messages disrupts fraudsters' predictable scripts, making automated fraud attempts more challenging. This unpredictability forces scammers to adapt, buying time for detection systems to identify and block suspicious calls. 

According to a 2024 report, 69% of contact center decision-makers believe spam and fraud against commercial outbound calling are impacting their company's bottom line. Additionally, 96% expressed interest in adopting enterprise authentication and spoof protection technology to mitigate fraud attempts.

Inject noise into calls

Adding background noise or lowering audio quality during calls stops fraudsters from getting clean voice samples. These poor-quality recordings make voice cloning and deepfake attacks far less effective at fooling agents or automated systems.

A 2025 report by Smartnumbers highlights that 59% of fraudulent activity flagged by their customers relates to fraudsters suppressing account notifications or making minor changes to customer accounts to prepare for attacks.

Regular software updates

Keeping all contact center software up to date closes security holes and fixes vulnerabilities before fraudsters exploit them. 

Updating systems frequently also adds new security features that can detect or block fraudulent activity.

Secure third-party integrations

Evaluating the security of every third-party service linked to your contact center helps prevent fraudsters from using those connections to breach systems. Vendors must adhere to strict security protocols to protect customer data and prevent unauthorized access. 

This approach is essential in safeguarding against potential vulnerabilities introduced through external integrations.

Interactive training resources

Providing hands-on fraud prevention training for every employee involved in customer interactions raises awareness and sharpens skills. Regular sessions about current payment security threats and how to avoid data leaks keep staff ready to respond quickly to risks.

A 2025 report by Smartnumbers found that 28% of fraudulent activity flagged by their customers is due to fraudsters attempting to validate or steal more customer data. Training should include how to spot red flags, follow escalation protocols, and use indicators like repeat calls or withheld numbers to identify threats early. Regular refreshers and post-incident reviews help teams stay updated and responsive to evolving fraud tactics. 

By strengthening human judgment alongside technical defenses, companies can detect threats faster and reduce the chances of successful fraud attempts.

Why Interaction Control is the New Frontline of Contact Center Security

Every call center fraud attempt hinges on one constant: interaction between the fraudster and the victim. Yet most security frameworks, rooted in the Confidentiality, Integrity, and Availability (CIA) triad, are designed to authenticate access, and not detect malicious intent.

As a result, fraudsters can exploit even PCI-compliant systems simply by sounding legitimate. Traditional security tools react to known fraud patterns, but social engineering evolves faster than rule-based defenses, leaving critical gaps. This puts customer payment data at risk and drives organizations to layer on more security, often increasing friction and damaging the customer experience.

Platforms like Sycurio enable this shift. For example, Sycurio.Voice masks customer payment data through DTMF tones, removing sensitive information from agent interaction and call recordings, maintaining both security and a seamless experience. By proactively managing engagement from the first touchpoint, companies can intercept fraud before it escalates.
