Understanding the Most Common Types of Payment Fraud

Online payment fraud eats into Fintech’s profits and shatters customer trust. Some of the most common types of fraud include:

  • Card-Not-Present (CNP) Fraud

CNP fraud occurs when transactions are made without the physical presence of a card, common in e-commerce. 

Fraudsters typically obtain stolen card information, including the card number, expiration date, and security code, through various means such as data breaches, phishing scams, or skimming devices. 

They then use this stolen information to make unauthorized purchases online without needing the physical card. CNP fraud losses were $8.75 billion in 2022 and are projected to reach $10.16 billion by the end of 2024.

  • Identity Theft and Synthetic Identity Fraud

Identity theft involves using stolen personal information, while synthetic identity fraud creates fake identities from real and fabricated data. Synthetic identity fraud costs banks $6 billion annually, as fraudsters use these identities to open accounts and apply for loans.

  • Phishing and Social Engineering Scams

Phishing and social engineering scams deceive individuals into revealing sensitive information. In 2022, these scams caused $8.3 billion in losses in the US, affecting approximately 234,000 victims with an average loss of $35,000 each. Fraudsters pose as trusted entities to extract personal data.

  • Chargeback Fraud and Friendly Fraud

Chargeback fraud, or friendly fraud, occurs when customers dispute legitimate charges to get refunds while keeping the products. This results in billions of dollars in losses, increased operational costs, and reputational damage for merchants.

  • Account Takeover (ATO) Fraud

ATO fraud involves unauthorized access to user accounts through stolen credentials, leading to unauthorized transactions and changes to account details. In 2023, about a quarter of US adults reported being victims of ATO attacks, causing financial losses and eroding customer trust.

The Cost of Fraud Beyond Financial Losses

Online payment fraud’s impact goes beyond immediate losses, threatening a fintech’s very existence in the digital economy. This makes investing in robust payment fraud prevention solutions a necessity for the long-term growth and sustainability of fintech companies.

  • Direct Financial Impact of Fraudulent Transactions

Fraudulent transactions bleed fintechs financially through chargebacks, lost revenue, and increased operational expenses. Chargebacks not only entail the loss of transaction value but also incur additional fees, straining operational budgets. The ripple effect of these transactions extends to lost revenue and the tangible costs of addressing fraud, diverting resources from innovation and growth.

  • Indirect Costs and Reputational Damage

Beyond direct losses, fraud increases customer support costs and cart abandonment rates. Legal liabilities can also arise. The long-term impact on a fintech’s reputation is profound. A single high-profile fraud incident can erode customer trust and deter new users. For example, a data breach can make headlines, leading to a loss of business and a challenging recovery path.

Prevent Payment Fraud: Building a 360-Degree Strategy 

With new fraud tactics emerging every day, the million-dollar question is “How can fintechs stay ahead of the curve?” The answer lies in relying on advanced technology and innovative strategies. Let’s explore what technologies help in developing a comprehensive strategy for fraud.

1. Advanced AML Transaction Monitoring

Traditionally, AML transaction monitoring used rule-based systems, prone to generating false positives and reactive to known patterns. However, these systems struggled to keep pace with evolving criminal methodologies, leaving financial institutions vulnerable to emerging threats.

Let’s look at how adding machine learning models and behavioral analytics helps take AML transaction monitoring to the next level.

  • Machine Learning Models

Machine learning and AI models excel in analyzing entity relationships across devices, identities, transactions, and data points. By examining these intricate connections, they can uncover complex criminal activities that might otherwise go undetected.

Models like Random Forest, XGBoost, and Neural Networks detect complex fraud patterns by analyzing vast data sets. One of the key advantages of machine learning models in AML transaction monitoring is their ability to reduce false positives.

For example, a machine learning model can analyze a customer’s transaction history, device usage patterns, and geographic locations to identify anomalies that may indicate account takeover or identity theft. This level of granular analysis is challenging for traditional rule-based systems.

  • Behavioral Analytics

Machine learning models can be further enhanced by integrating behavioral analytics. It involves analyzing customer behavior patterns, such as transaction frequency, spending habits, and geographic locations, to identify deviations from established norms.

FinTechs can gain a comprehensive understanding of customer activities, enabling more effective risk profiling and targeted investigations.

Case Study: How HSBC Shaped AML Strategy With AI

HSBC, one of the world’s largest banks, faced significant challenges in its anti-money laundering (AML) efforts.

Challenges

  • High False Positives: The traditional rules-based AML system generated numerous false positives, requiring extensive manual reviews.
  • Inefficiency: The manual review process was time-consuming and inefficient, delaying the detection of suspicious activities.
  • Complexity: Identifying criminal networks and sophisticated money laundering patterns was difficult with the existing system.

Solution

HSBC partnered with Google Cloud to develop and implement AML AI. This AI-powered solution uses machine learning to autonomously detect suspicious activities without predefined rules.

Results

  • Increased Detection Accuracy: AML AI identified 2-4 times more suspicious activities than the previous system.
  • Reduced False Positives: False positives were reduced by over 60%, allowing investigators to focus on genuinely suspicious cases.
  • Faster Processing: The time to detect suspicious accounts was reduced to eight days, significantly improving response speed.
  • Enhanced Network Detection: AML AI could identify criminal networks by spotting known money-laundering patterns, which the rules-based system struggled to do.

2. Network Graph Analytics

Network graph analytics helps financial institutions uncover hidden relationships and patterns within transaction data, providing deeper insights into potential fraudulent activity. This is achieved through various network graph analytics techniques, including:

  • Visualization of Transaction Networks

Graph databases model transactions and accounts for AML investigations. These databases represent entities (such as accounts and transactions) as nodes and their relationships as edges. Visualization techniques like force-directed layouts and color-coding help analysts trace the flow of funds and identify suspicious patterns.

For example, a force-directed layout can visually represent the connections between accounts, making it easier to spot anomalies and trace the movement of illicit funds. Color-coding can highlight different types of transactions or risk levels, allowing analysts to quickly focus on areas of concern.

  • Centrality Measures

Centrality measures in network analysis help identify key nodes within a transaction network. These measures, such as degree centrality and betweenness centrality, highlight the most influential nodes that could be central to fraudulent activities. Degree centrality measures the number of connections a node has, while betweenness centrality measures the extent to which a node lies on the shortest path between other nodes. 

By focusing on these critical points, analysts can prioritize their investigations and uncover significant scams. For instance, a node with high betweenness centrality might indicate a central account used to funnel illicit funds.

  • Community Detection

Community detection algorithms, like Louvain, Girvan-Newman, Infomap, and Spectral clustering, identify clusters within transaction networks based on connectivity patterns. These clusters can reveal groups of accounts that are working together in fraudulent activities. 

Detecting these communities helps in understanding the broader network of fraud and taking targeted action against it. For example, the Louvain algorithm can identify densely connected subgroups within a network, which might represent a coordinated fraud ring.

  • Real-Time Detection

Real-time detection is crucial for immediate identification of suspicious transactions. Network graph analytics enables real-time analysis by continuously monitoring transaction data and integrating alerts for prompt risk mitigation. This capability ensures that potential fraud is detected and addressed as it happens, minimizing the impact on the financial institution.

Technological requirements for real-time analysis include high-performance graph databases, efficient algorithms for real-time processing, and integration with alert systems to notify analysts of suspicious activities immediately.

Balancing Security with Customer Experience

In the fintech industry, striking the right balance between robust security measures and a seamless customer experience is paramount. While security is crucial for safeguarding sensitive financial data and transactions, overly strict measures can inadvertently create friction, leading to customer frustration and potential abandonment.

  • Understanding the Impact of Friction on Users

Excessive security measures, such as multiple authentication steps or lengthy verification processes, can create unnecessary friction for users. This friction can manifest in various ways, including increased cart abandonment rates, customer frustration, and a negative perception of the fintech platform.

Additionally, false positives, where legitimate transactions or users are incorrectly flagged as suspicious, can further exacerbate the problem. These false alarms not only disrupt the user experience but also strain resources as teams investigate and resolve these incidents.

  • Frictionless Fraud Prevention with Risk-Based Authentication

Risk-based authentication is a powerful strategy that tailors security measures to the level of risk associated with a particular transaction or user activity. By analyzing various factors, such as location, device, and behavioral patterns, fintech platforms can dynamically adjust the authentication requirements.

For low-risk activities, such as checking account balances or making small transactions, a streamlined authentication process can be employed, minimizing friction and enhancing the user experience. Conversely, for high-risk activities like large fund transfers or account changes, more stringent authentication measures can be implemented to ensure maximum security.

  • Key Regulations and Industry Standards

Fraud prevention in the fintech industry is governed by various regulations and industry standards, such as the Payment Card Industry Data Security Standard (PCI DSS), the General Data Protection Regulation (GDPR), and Anti-Money Laundering (AML) and Know Your Customer (KYC) requirements.

Compliance with these regulations is crucial for fintech companies to ensure the protection of sensitive financial data, prevent financial crimes, and maintain transparency in their operations. Failure to adhere to these standards can result in severe penalties, reputational damage, and loss of customer trust.

However, it is essential to note that regulations and industry standards are constantly evolving to keep pace with the dynamic fintech landscape and emerging threats. Fintech companies must stay vigilant and regularly review their compliance strategies to ensure they remain aligned with the latest guidelines and best practices.
