OTP Fraud And Its Prevent Measures For Businesses & Customers
You received an unsolicited call from someone claiming to be from your bank. They’re trying to convince you that your account has been compromised and that you must act fast. To build trust, they even mention the name of a recent transaction, and they seem to know a lot about you. Before you know it, you share a one-time password to help them secure your account. Businesses use OTPs as an added layer of security during online transactions. As part of first-party fraud, scammers often pose as trusted institutions, like banks, to trick unsuspecting customers into sharing them. The good news is this article will help you understand how OTP fraud works so you can better protect yourself against it.
Anonybit’s biometric OTP solution can help you and your business avoid the costly repercussions of OTP scams. By preventing this in real-time, Anonybit can help you stop account takeover fraud before it impacts your customers and your business.
What Is A One-Time Password (OTP) Fraud?
An OTP, or one-time password, is a security feature that enables online users and service providers to secure transactions with additional protection. It is the process of authenticating an online communication or transaction with an OTP that the service provider sends to the customer’s registered mobile number or mail ID. As digital financial transactions and activity rose, this additional layer was introduced as a time-bound authentication mechanism for safe online transactions of sensitive data and money.
Fraudsters have found new means and schemes to receive the needed OTP code. One way is with SIM swaps, where they take over the victim’s phone number and so they will get any OTP that goes to the phone number. Another way involves tricking the user into revealing their OTP, which the fraudster then uses to complete a fraudulent transaction from another channel
How Dangerous Is OTP Fraud?
One-time password (OTP) fraud is a cybercrime in which fraudsters exploit the OTP authentication process to gain unauthorized access to accounts or conduct fraudulent transactions. OTP fraud occurs when criminals use various techniques to intercept or bypass the OTP verification process.
The goal is to steal the OTP, use it to access the victim’s accounts and commit financial fraud or identity theft.

Understanding the Limitations Of OTP Security
The security of one-time passwords (OTPs) is closely tied to the device receiving them. If a user’s smartphone or computer is compromised by malware or spyware, attackers can access OTPs. Keyloggers can capture OTPs as they are entered, and sophisticated malware can intercept OTPs directly from SMS messages and authentication apps. In the most common cases, the victims are socially engineered into handing over the code or the device or email is otherwise taken over by the fraudster so they receive the code directly.
In addition to inherent security weaknesses, OTPs can also be inconvenient for users, especially when required for every transaction or login. This can lead to user fatigue and potential security workarounds.

How Does OTP Fraud Happen?
Phishing methods top the list of the ways scammers steal one-time passwords. In this scheme, cybercriminals send fake emails or text messages that appear to come from legitimate sources, like banks, online retailers, telcos, credit unions, marketplaces and other providers. The messages often contain urgent requests that prompt the user to erify your account, resolve an issue or confirm a transaction or account details and call a number to complete the process.Once the user provides the OTP, the scammers are able to access their accounts.
Vishing: The Telephone Scam That Can Cost You Big
Vishing is another common tactic used by fraudsters to steal one-time passwords. This social engineering scheme involves scammers calling their victims, pretending to be representatives of reputable organizations banks or tax collection agencies. The scammer may claim that there has been suspicious activity on the user’s account and that they need the OTP to secure it. They exploit the user’s sense of urgency and trust, convincing them to provide the OTP over the phone. Once they have the OTP, again, they can bypass security measures and access your accounts.
Smishing: Don’t Get Hooked by Scam Texts
Smishing is a type of fraud where criminals use SMS messages to trick recipients into revealing personal information or financial details. These messages often impersonate legitimate organizations, creating a sense of urgency or fear to prompt recipients to take immediate action.
Man-in-the-Middle Attacks: An Insidious Type of OTP Fraud
In a man-in-the-middle attack, cybercriminals intercept the communication between you and a legitimate service provider. This typically occurs when you request an OTP for a transaction or login. The attacker positions themselves between you and the service provider, capturing the OTP as it is transmitted.
They can then use the intercepted OTP to gain unauthorized access to your account. This method is hazardous because the user may be unaware that their communication has been compromised.
In a related version of this, the fraudster takes control over the phone or email address that the OTP comes into and therefore doesn’t need to ask the user for it.

What Can A Scammer Do With An OTP?
If a scammer gets a hold of your one-time password, they can do all sorts of nasty things with it. One of the most common is to use it to bypass two-factor authentication on their way to taking over your accounts. With access to your online banking, email, or social media accounts, they can change account details or take over the account entirely.
Financial Transactions
If the OTP is linked to financial accounts, scammers can use it to initiate unauthorized transactions. This could involve transferring money, making purchases or setting up new payment methods under their control.
They may also drain your accounts or make fraudulent charges, which can be challenging to reverse, since there is no way to validate who actually entered the OTP.
Identity Theft
A scammer accessing your accounts can also gather personal information such as your name, address, social security number or other sensitive data. They can use this information to steal your identity, apply for credit in your name, redirect funds or engage in other fraudulent activities that can harm your credit score and financial reputation.
Access to Sensitive Information
For accounts containing sensitive or private information, such as email or cloud storage, bypassing OTP allows a a scammer to access personal documents, photos and communications. This information can be used for blackmail, extortion, or sold on the dark web to other criminals.
Spreading Malware or Phishing
With control over your email or social media accounts, scammers can send malware-infected links or phishing messages to your contacts. These messages appear to come from you, making them more likely to be trusted and opened, thus spreading the scam further.
Exploiting Security Loopholes
Once a scammer has access to one account, they may attempt to use that access to breach other accounts, mainly if you use the same login credentials across multiple platforms. They can explore other vulnerabilities or initiate account recovery processes that require minimal verification once they’re in.
The Global Landscape And Impact Of OTP Fraud On Businesses
OTP fraud has become a significant global issue, affecting individuals, businesses, and financial institutions across various regions. Fraudsters exploit vulnerabilities in OTP systems to carry out attacks, often leading to substantial monetary losses.
The impact of OTP fraud varies by region, but the underlying trend is a growing threat that demands more robust security measures.
OTP Fraud in the United States
OTP fraud has become a significant concern for consumers and financial institutions in the United States. According to Javelin Strategy & Research, American adults lost a total of $43 billion to identity fraud in 2023, with a significant portion attributed to OTP fraud.
This type of fraud is hazardous because it often targets individuals through:
- Phishing attacks
- SIM swapping
- Social engineering
- Convincing them to reveal their OTPs
OTP Scams
The Federal Trade Commission (FTC) has also reported an alarming increase in OTP-related scams. Fraudsters use various techniques to intercept or steal OTPs, often leading to unauthorized access to:
- Bank accounts
- Credit cards
- Other sensitive information
The growing reliance on mobile banking and online transactions has made OTPs a common target, highlighting the need for enhanced security protocols.
OTP Fraud in Europe
In Europe, the introduction of the Payment Services Directive 2 (PSD2) was intended to bolster online security by implementing Strong Customer Authentication (SCA), which includes OTPs. OTP fraud remains a significant concern as fraudsters continue evolving tactics to bypass security measures.
European Fraudster Activities
Reports from Europol and other cybersecurity agencies have highlighted the ongoing challenges European countries face in combating OTP fraud. European fraudsters have increasingly turned to:
- Phishing
- Man-in-the-middle attacks
- SIM swapping to intercept OTPs, allowing them to gain unauthorized access to accounts and financial data
Despite the stricter regulations, the persistence of OTP fraud in Europe demonstrates the need for continuous innovation in security technologies.
OTP Fraud in India
India has also seen a rapid surge in OTP fraud cases, driven by the widespread use of mobile banking and the inherent vulnerabilities in SMS-based OTP systems. Reports indicate that millions of cases are reported annually, making OTP fraud one of the country’s most prevalent forms of financial crime.
Escalating Threat in India
A February 2024 report revealed that nearly 18% of respondents in India had experienced Account Takeover (ATO) attacks, many of which involved OTP fraud. 62% of these incidents occurred within the past year, underscoring the escalating threat.
The widespread adoption of digital payment systems and the increasing sophistication of fraudsters have contributed to the rise in OTP fraud, prompting calls for more secure alternatives and stricter regulations.
How To Protect From OTP Fraud: 5 Best Prevention Techniques For Businesses
1. Adopt Biometric Authentication
Biometric authentication, such as fingerprint scanning or facial recognition, is the most effective technique to mitigate OTP fraud. Unlike OTPs, which can be intercepted or stolen through various phishing and social engineering methods, biometric data is unique to each individual and cannot be easily replicated by fraudsters.
Biometric OTP
By combining OTPs with biometrics, organizations can significantly enhance their security measures. Even if an OTP is compromised, the fraudster cannot gain access without the user’s biometric verification.
Biometric authentication, like Anonybit’s solution, provides a robust defense against OTP fraud because it ties the authentication process to something the user is rather than something they know or have. This makes it much harder for attackers to bypass the security system, offering a higher protection than relying on traditional OTPs alone.
2. MFA (Multi-Factor Authentication)
Multi-factor authentication (MFA) is an essential strategy for enhancing security beyond passwords and OTPs. By requiring two or more verification methods—such as combining an OTP with a biometric scan—MFA makes it significantly more difficult for fraudsters to gain unauthorized access.
Multi-Factor Security
Even if one factor, such as an OTP, is compromised, the additional authentication steps provide a crucial barrier to entry. According to Microsoft research, multi-factor authentication blocks 99.9% of all attacks on individual accounts.
Verizon’s 2020 Data Breach Investigations Report found that 80% of accounts are breached by password failure. Eliminating or reducing dependency on passwords can save both costs and prevent fraud.
3. OTP Autofill
Combining biometrics or MFA with autofill technologies provide a truly unique opportunity to revolutionize security and convenience in digital authentication. Unlike traditional OTPs, which rely on randomly generated codes sent via SMS or email, biometric OTPs use unique biological characteristics—such facial scans—to generate and verify one-time passwords. This method enhances security by tying authentication to the individual’s physical identity, making it much harder for unauthorized users to gain access, as stated earlier. Autofill functionality further streamlines the process by automatically filling in the OTP during login or transaction procedures, reducing friction and improving user experience and ensuring that the user cannot be socially engineered to hand over the OTP to a fraudster.
4. Educate Users
Educating users about the risks associated with OTP fraud is crucial. Regular training and awareness programs should be conducted to inform users about the dangers of phishing, vishing and other forms of social engineering :designed to steal OTPs.
Users should be taught to recognize suspicious messages or requests for OTPs and encouraged to verify the legitimacy of any request before providing their information.
5. Monitor and Detect Fraud
Implementing advanced fraud monitoring systems can help organizations detect anomalies and suspicious activities related to OTP usage.
These systems can track unusual patterns, such as multiple OTP requests from different locations or devices, and flag potential fraud attempts in real-time. Early detection and response can prevent fraudsters from successfully exploiting compromised OTPs.
