Fintech fraud refers to any deceptive or illegal activity within the financial technology (fintech) industry. Fintech uses technology to improve and automate financial processes for a wide range of financial services and products, including online banking, mobile payments, peer-to-peer lending, cryptocurrency exchanges, and digital wallets. Because of the high volume of customer data that circulates throughout fintech ecosystems, fintech businesses are prime targets for fraudulent actors: there was a 39% increase in suspected digital fraud attempts in the financial services industry from 2019 to 2022.

This guide will explain how to prevent and detect fintech fraud, the different types of fintech fraud, and how fintech fraud impacts businesses.

Types of fintech fraud

Each type of fintech fraud presents different challenges to consumers and financial institutions. Types of fintech fraud include:

  • Identity theft: Criminals steal personal information to access financial services, open new accounts, or make unauthorized transactions.

  • Payment fraud: Criminals use stolen credit card information or hijacked online payment accounts to complete unauthorized transactions.

  • Account takeover (ATO): Fraudulent actors obtain a user’s login credentials, often through phishing, social engineering, or by using previously leaked data, and gain unauthorized access to financial accounts.

  • Loan and credit fraud: Criminals use falsified details to apply for loans or credit which they do not repay, impacting the credit scores of individuals whose identities they stole, and hurting financial institutions.

  • Money laundering: Criminals launder money by transferring illicit funds through multiple accounts or across borders to obscure their origin and integrate them into the legitimate financial system.

  • Phishing scams: Fraudulent actors use deceptive emails or messages that mimic legitimate institutions to trick users into providing sensitive information such as passwords, credit card details, and account numbers.

  • Investment scams: Fraudulent actors offer scam investment opportunities, often focused on new or emerging financial technologies, that promise unusually high returns. These might include cryptocurrency schemes, which can be less regulated and harder for consumers to understand.

  • Insider fraud: Employees within a fintech company abuse their access to systems and information to commit fraud against the company or its customers.

  • SIM swap fraud: Fraudulent actors take control of a victim’s mobile phone number by tricking the service provider into swapping the number to a SIM card held by the fraudulent actor. They use that access to intercept one-time passwords and account recovery messages.

  • Merchant identity fraud: Fraudulent actors set up fake merchant accounts to process payments from stolen credit card data or to legitimize other fraudulent activities.

How fintech fraud affects businesses

Fintech fraud negatively impacts businesses directly and indirectly. These impacts include:

  • Financial loss: The most direct impact of fintech fraud on businesses is financial loss. This can occur due to unauthorized transactions, payment fraud, or loan fraud. For example, if a fraudulent actor accesses a company’s payment system, they can make unauthorized withdrawals or transactions that lead to direct financial losses. Businesses often have to cover the cost of chargebacks resulting from fraudulent transactions.

  • Increased operating costs: Combatting fintech fraud requires a major investment in security measures such as advanced fraud detection systems and staff training. These measures increase the overall operating expenses for businesses.

  • Regulatory and compliance issues: Typically, fintech companies must follow strict regulatory requirements designed to protect consumer data and prevent fraud. If a business falls victim to fraud, it might face scrutiny from regulators and be subject to fines, sanctions, or additional compliance requirements. This directly impacts finances and demands the business set aside more resources to manage compliance and regulatory reporting.

  • Reputational damage: Fraud can damage a fintech company’s reputation, making it difficult to attract and retain customers. Customers might lose trust in the business’s ability to protect their financial information and transactions. After an incident of fraud, businesses often need to engage in extensive PR and customer service efforts to rebuild trust.

  • Operational disruption: Responding to a fraud incident with investigation and remediation efforts can divert resources from normal business operations, and potentially affect service delivery and operational efficiency. For example, if a security breach requires a business to shut down certain systems, the resulting downtime can affect sales and services.

  • Delayed innovation: The need to focus on security and fraud prevention can impact a fintech company’s roadmap. Resources that the business might otherwise use to develop new products or improve services might instead be directed toward improving security measures and investing in fraud prevention.

How to prevent fintech fraud

Preventing fintech fraud requires strong policies, processes, and tools. Here are several effective strategies for safeguarding fintech platforms and their users.

  • Strong authentication processes: Strong authentication mechanisms such as multi-factor authentication (MFA), biometric verification (such as fingerprint or facial recognition), and strict password policies make unauthorized access much more difficult.

  • Advanced encryption: Encrypting data at rest and in transit with strong, up-to-date encryptions standards ensures that data cannot be easily understood or misused, even if fraudulent actors intercept it.

  • Fraud detection systems: Artificial intelligence and machine learning can help detect and prevent fraud in real time by analyzing transaction patterns and flagging anomalies that deviate from typical user behaviors, allowing businesses to intervene quickly.

  • Regular security audits: Regular audits of security infrastructure (including both internal audits and third-party security assessments) can help identify and address vulnerabilities before attackers can exploit them.

  • Employee training: Human error can often lead to security breaches. Holding regular employee training sessions on the latest fraud prevention techniques, phishing tactics, and security best practices can help prevent this.

  • Secure software development practices: Prioritize security at every stage of software development. This includes conducting regular code reviews, integrating security testing into the development process, and using secure coding practices.

  • Transaction limits and alerts: Setting limits on transaction sizes or frequencies can mitigate the impact of fraud. Instant transaction alerts can also help customers quickly spot unauthorized transactions.

  • API security: Fintech companies often rely on APIs for integration with other services and partners. APIs must be secured with proper authentication, encryption, and the limiting of data access based on user or service roles.

  • Monitoring and response: Building a dedicated team to watch for fraud and respond quickly can minimize damage. This team should be equipped with the tools and authority to take immediate actions such as freezing accounts or transactions if they suspect fraud.

  • Customer education: Educate customers about fraud risks and safe practices. Well-informed customers are less likely to fall prey to phishing or other forms of social engineering.

How to detect fintech fraud

Detecting fintech fraud swiftly and accurately can minimize financial losses and protect customer relationships. These strategies and technologies help identify fraudulent activities as they occur.

  • Real-time transaction monitoring: Real-time monitoring systems use predefined rules and machine learning algorithms to analyze transactions as they happen. They can detect patterns or anomalies that deviate from normal transaction behaviors such as unusually large transactions or high-frequency activities in a short time.

  • Behavioral analytics: Analyzing the typical behavior of a user to establish a baseline profile allows you to notice deviations from this profile that should trigger an alert. A sudden change in location, access through an unfamiliar device, or an unusual transaction time might indicate fraudulent activity.

  • Machine learning and AI: Advanced algorithms can learn from historical data to continuously improve their fraud detection capabilities, identifying subtle and complex fraud patterns that are difficult for traditional methods to detect.

  • Link analysis: Link analysis examines the relationships between different entities (such as users, accounts, devices, and transaction locations) to detect fraud networks and collusion, potentially revealing connections and patterns that might suggest coordinated fraud schemes.

  • Biometric verification: Biometric verification methods such as fingerprint scanning, facial recognition, or voice authentication provide a high level of security and can help prevent unauthorized access.

  • Geolocation technology: Detecting the geographic origin of transactions can help identify discrepancies that indicate fraud. For example, if a customer’s credit card is used to make a purchase in a country where they do not typically spend time, there’s a higher chance this is a fraudulent transaction.

  • Device fingerprinting: Device fingerprinting logs a device’s characteristics, such as the operating system, browser type, IP address, and even installed font styles. A sudden change in device fingerprint without a corresponding user notification might indicate fraud.

  • Data source integration: Combining data from various sources such as transaction logs, user access logs, customer profiles, and external databases provides a more comprehensive view of factors that might indicate fraud.

  • Dark web monitoring: Monitoring the dark web for leaked credentials or information related to your organization can provide early warnings about potential breaches or fraud schemes.

  • Employee and customer reporting mechanisms: Creating easy avenues for employees and customers to report suspicious activities can help your business detect fraud quickly. Insiders or attentive customers might notice irregularities that systems overlook.

  • Regular security audits and penetration testing: Auditing the security infrastructure and conducting penetration testing on an ongoing basis can help identify potential vulnerabilities that fraudulent actors could exploit.

How to respond to fintech fraud

Taking quick and decisive action—combined with thorough follow-up—can minimize the damage from fintech fraud and reinforce the security and trust of your fintech services. Here is how to handle an incident of fintech fraud.

  • Take immediate action: As soon as you detect fraud, act swiftly to contain the incident. This might include freezing affected accounts, blocking suspicious transactions, or changing access credentials.

  • Verify the incident: Confirm that the suspected activity is indeed fraudulent. Sometimes, what appears to be fraud might be a customer making unusual but legitimate transactions.

  • Assess the impact: Determine the scope and impact of the fraud. Understand how it occurred, which accounts are affected, and the amount of financial exposure.

  • Notify affected parties: Inform all impacted stakeholders including customers, banks, and payment networks. Transparency is key to maintaining trust and, in many jurisdictions, notification is a regulatory requirement.

  • Engage law enforcement: In cases of major fraud, contact the appropriate law enforcement agencies. They can assist with investigations and recovering funds.

  • Improve security measures: Reinforce security measures immediately to prevent further incidents. This could involve updating security protocols, improving monitoring systems, or implementing additional authentication measures.

  • Monitor for repercussions: After addressing the incident, continue to monitor the situation for any further suspicious activities. Fraudulent actors often attempt multiple access points or methods.

  • Review and learn: Conduct a post-incident review to understand how the fraud was possible and identify any weaknesses in your fraud prevention strategies. Use these insights to strengthen your systems and processes.

  • Educate your team and customers: Share knowledge about the incident and lessons learned with your team and customers to help them recognize and prevent future fraud.

  • Update your incident response plan: Revise your response plan based on the experience to improve how you handle future incidents.
