Interview Questions for ACH Fraud Detection

ACH fraud encompasses various schemes exploiting the Automated Clearing House (ACH) network for unauthorized funds transfers. These schemes are constantly evolving, but some common types include:

• Business Email Compromise (BEC): Fraudsters impersonate company executives via email to trick employees into authorizing ACH payments to fraudulent accounts. For example, they might send an email instructing the finance department to change vendor payment details, leading to funds being diverted.
• Check Washing: A physical check is stolen and the payee information is altered, then deposited via ACH. The original check information is chemically removed, and fraudulent details are added.
• Data Breaches: Stolen customer data, including banking information, can be used to initiate unauthorized ACH debits or credits.
• Account Takeover: Fraudsters gain unauthorized access to a business or individual’s bank account and initiate fraudulent ACH transactions.
• Synthetic Identity Fraud: Fraudsters combine real and fabricated personal information to create synthetic identities, then open accounts and initiate fraudulent ACH transactions.
• Malware and Ransomware Attacks: Malware can be used to steal credentials or directly initiate ACH transactions from compromised systems.

Understanding the nuances of each scheme is crucial for effective fraud prevention and detection.

Throughout my career, I’ve extensively used various ACH transaction monitoring systems, ranging from basic rule-based systems to sophisticated AI-powered solutions. I have experience with systems that leverage real-time transaction monitoring, anomaly detection, and machine learning algorithms to identify suspicious activity. My experience includes implementing and managing these systems, configuring alerts, and tuning detection rules to minimize false positives while maximizing the detection of fraudulent transactions. For instance, I was instrumental in implementing a system that utilized behavioral biometrics to identify unusual payment patterns, resulting in a significant reduction in ACH fraud losses for a major financial institution. Specific software names are usually proprietary information and are not disclosed, but I am proficient in working with various industry-standard solutions and I’m comfortable customizing these to meet specific business needs.

Identifying suspicious ACH transactions involves a multi-faceted approach combining rule-based systems and machine learning. I typically start by analyzing transaction details like the amount, frequency, recipient, and origin. I look for anomalies compared to historical patterns. For example, an unusually large payment to a new vendor would raise a red flag. Then, I correlate this transactional data with other data points, such as IP address geolocation and device information. Machine learning models help identify subtle patterns indicative of fraud, such as velocity of transactions or the clustering of similar patterns. Ultimately, my process relies on a blend of automated systems and human expertise to make informed decisions.

Key indicators of ACH fraud can be categorized into several areas:

• Unusual Transaction Amounts: Significantly higher or lower than usual transactions.
• Unexpected Payment Recipients: Payments to unfamiliar or newly added vendors or individuals.
• Frequent Transactions to the Same Recipient: A series of small transactions adding up to a substantial amount.
• High-Frequency Transactions: A sudden increase in the number of transactions.
• International Payments: Payments to accounts in countries with high fraud risk.
• Unusual Payment Timing: Transactions occurring outside of normal business hours or on weekends.
• Discrepancies in Payment Details: Mismatched addresses or other inconsistent information.
• Requests for Immediate Payment: Urgent requests to make payments with little to no justification.
• Multiple Payments to the Same Account in a Short Period: This could indicate fraudsters trying to bypass detection limits.
• Lack of supporting documentation: Absence of proper invoices or purchase orders.

Recognizing these indicators requires a combination of robust monitoring systems and experienced human analysts who understand the specific context of each transaction.

Regulations surrounding ACH fraud prevention are stringent and vary depending on jurisdiction. In the US, key regulations include the Bank Secrecy Act (BSA), which requires financial institutions to implement anti-money laundering (AML) programs, including measures to detect and prevent ACH fraud. Regulations from agencies like the Federal Reserve and the Office of the Comptroller of the Currency (OCC) further guide banks in implementing effective fraud prevention controls. Failing to comply with these regulations can result in severe penalties, including fines and reputational damage. These regulations also necessitate the implementation of strong customer identification programs (CIP), robust transaction monitoring systems, and thorough investigations of suspicious activity. Further, the Payment Card Industry Data Security Standard (PCI DSS) influences ACH security indirectly, particularly concerning data security and safeguarding sensitive customer information that might be leveraged in ACH fraud.

My understanding of NACHA rules and regulations is comprehensive. NACHA (National Automated Clearing House Association) sets the operating rules for the ACH network. These rules cover various aspects of ACH transactions, including origination, processing, and risk management. I’m familiar with the different ACH transaction types, the rules governing the various transaction types (like CCD, PPD, WEB), and the requirements for data integrity and security. Knowing these rules is paramount to minimizing operational risk and ensuring compliance. For example, understanding the rules around return reasons is critical for investigating and resolving ACH fraud cases efficiently. Staying updated on NACHA’s ongoing rule changes is an essential aspect of maintaining a secure and compliant ACH processing environment.

Investigating and resolving ACH fraud cases involves a systematic approach. It starts with verifying the fraudulent transaction by gathering evidence from various sources – transaction records, bank statements, supporting documentation, and communication logs. Then, I work with internal and external stakeholders, such as law enforcement and other banks involved, to determine the scope and source of the fraud. This investigation may include interviewing involved parties, analyzing network traffic logs, and working with digital forensics experts if necessary. Once the source of fraud has been confirmed and validated, steps are taken to recover the funds. This may include collaborating with financial institutions, initiating chargebacks, and potentially pursuing legal action against the perpetrators. Documentation of the entire investigation process is crucial for future reporting and regulatory compliance. The ultimate goal is not only to recover lost funds but also to prevent similar instances in the future by implementing improved security measures and updating monitoring systems.

My approach to ACH fraud detection leverages a multi-faceted toolkit combining advanced analytical techniques with robust software solutions. I utilize a combination of rule-based systems, machine learning algorithms, and network analysis to identify suspicious transactions.

• Rule-based systems: These define specific criteria, like unusually large transaction amounts or multiple transactions from the same IP address in a short period, flagging potential fraud.
• Machine learning: I employ supervised and unsupervised learning models (e.g., anomaly detection algorithms like Isolation Forest or One-Class SVM) to identify patterns indicative of fraudulent activity that might be missed by rule-based systems. This allows for the detection of more sophisticated and evolving fraud schemes.
• Network analysis: This technique helps visualize relationships between accounts, businesses, and individuals involved in transactions, revealing potential money laundering schemes or coordinated fraud rings. For example, detecting unusual connections between seemingly unrelated accounts can be a crucial indicator.
• Data Visualization Tools: Tools like Tableau or Power BI are crucial for creating dashboards displaying key metrics and fraud trends, allowing for proactive identification of emerging threats.

Imagine it like this: rule-based systems are like having a metal detector – it’s good at finding obvious things. Machine learning is like having a trained bloodhound – it can sniff out more subtle patterns. Network analysis provides the map to see how everything connects.

Data analysis is the cornerstone of effective ACH fraud detection. I utilize a structured approach, beginning with data collection and cleansing, followed by exploratory data analysis, and finally, predictive modeling.

• Data Collection and Cleansing: This involves gathering transaction data from various sources, ensuring data quality through cleaning, and handling missing values. This could include transaction amounts, dates, payer and payee information, IP addresses, and geolocation data.
• Exploratory Data Analysis (EDA): EDA involves summarizing and visualizing the data to identify patterns, anomalies, and potential relationships between variables. This step often involves creating histograms, scatter plots, and correlation matrices to understand the data’s characteristics. For example, identifying a sudden spike in transactions from a particular geographic location might be a red flag.
• Predictive Modeling: Based on the insights from EDA, I develop and deploy machine learning models (e.g., logistic regression, random forests, gradient boosting machines) to predict the probability of a transaction being fraudulent. These models are trained on historical data, with known fraudulent and legitimate transactions, to learn patterns that distinguish between the two.

For instance, I might analyze historical data to find that transactions exceeding $10,000 from previously unknown accounts originating from specific IP addresses are highly correlated with fraud. This insight helps refine my fraud detection models.

My experience encompasses a range of fraud prevention software, including both commercially available solutions and custom-built systems. I’m proficient in using platforms that offer real-time transaction monitoring, anomaly detection capabilities, and robust reporting features.

• Real-time transaction monitoring: This allows for immediate identification of suspicious activity and enables timely intervention to prevent losses.
• Anomaly detection: Software incorporating machine learning algorithms helps identify deviations from established patterns, even those not explicitly defined by rules.
• Case Management: Features that allow for efficient tracking and investigation of suspicious transactions, providing detailed audit trails.
• Integration Capabilities: I have experience integrating fraud prevention software with existing banking systems and databases to ensure seamless data flow and analysis.

For example, I’ve worked extensively with a system that integrates with our core banking system to analyze transaction data in real-time, instantly flagging high-risk transactions and providing alerts to our investigation team. This proactive approach significantly reduces fraud losses.

Assessing ACH fraud risk requires a holistic approach, encompassing both internal and external factors. I use a combination of quantitative and qualitative methods.

• Quantitative Analysis: This involves analyzing historical fraud data to identify trends, frequency, and cost of fraud events. Key metrics include the number of fraudulent transactions, the total value of losses, and the average time to detect fraud.
• Qualitative Analysis: This includes evaluating internal controls, employee training, and the organization’s overall security posture. I conduct risk assessments considering factors like the strength of authentication procedures, access controls, and employee awareness of fraud schemes.
• External Factors: Keeping abreast of emerging fraud trends and threats within the financial industry is critical. This includes staying updated on evolving attack vectors and regulatory changes.

Imagine it like a house security assessment: quantitative analysis is like checking the locks and windows, qualitative is assessing the overall security system, and external factors are considering neighborhood crime rates.

My strategies for mitigating ACH fraud risk are multi-layered and focus on prevention, detection, and response.

• Prevention: This includes implementing strong authentication methods (e.g., multi-factor authentication), robust access controls, and employee training programs to raise awareness of potential fraud schemes. Regular security audits and penetration testing are also vital.
• Detection: Leveraging the tools and techniques mentioned previously (rule-based systems, machine learning, network analysis) are crucial for timely identification of fraudulent activity. Real-time monitoring and alert systems are essential.
• Response: This involves establishing clear incident response procedures, including steps for investigation, containment, remediation, and post-incident analysis. Close collaboration with law enforcement and financial institutions is crucial for recovering losses and prosecuting perpetrators.

A layered approach is crucial; it’s like building a castle with multiple layers of defense—each layer adds to the overall security, making it much harder for attackers to breach.

Communicating findings from ACH fraud investigations requires clarity, conciseness, and a focus on actionable insights. I tailor my communication to the audience – whether it’s technical staff, management, or regulatory bodies.

• Executive Summaries: For senior management, I provide concise summaries highlighting key findings, impacts, and recommended actions.
• Detailed Reports: For technical teams, I provide detailed reports with data visualizations, timelines, and technical analyses to support the findings.
• Regulatory Reporting: When required, I prepare reports for regulatory bodies, adhering to strict reporting standards and guidelines.
• Data Visualization: Using charts, graphs, and dashboards is effective in presenting complex data in a readily understandable way.

For example, a graph showing the trend of fraudulent transactions over time can immediately highlight patterns and inform strategic decision-making.

I have extensive experience in developing and implementing ACH fraud prevention policies. My approach involves a thorough understanding of the organization’s specific risks, regulatory requirements, and best practices.

• Risk Assessment: Conducting thorough risk assessments to identify vulnerabilities and prioritize areas needing attention.
• Policy Development: Drafting comprehensive policies that cover authentication, authorization, access control, transaction monitoring, and incident response.
• Implementation and Training: Working with stakeholders to ensure effective implementation of policies and providing training to employees to increase awareness and compliance.
• Monitoring and Review: Regularly monitoring the effectiveness of policies and making adjustments as needed based on evolving threats and industry best practices.

I view policy development as an iterative process. It’s not a one-time event but rather a continuous improvement cycle to adapt to the ever-changing landscape of fraud techniques.

Staying ahead in ACH fraud requires a multi-pronged approach. I consistently monitor industry publications like the NACHA (National Automated Clearing House Association) Operational Letters and advisories, which provide crucial updates on emerging threats and best practices. I also actively participate in webinars and conferences hosted by organizations such as the Association of Certified Fraud Examiners (ACFE) and attend specialized workshops focused on emerging payment fraud schemes. Furthermore, I subscribe to reputable cybersecurity newsletters and follow key thought leaders and researchers on social media platforms dedicated to fraud prevention. Finally, internal data analysis within our organization is critical, allowing me to identify trends and patterns in our own ACH transactions that might foreshadow future attacks.

Think of it like a detective: you need to know the criminal’s methods before you can catch them. Staying current on these industry publications is like reading the criminal’s playbook.

I have extensive experience collaborating with law enforcement agencies on ACH fraud investigations. This typically involves providing detailed transaction data, including timestamps, originating accounts, and beneficiary details. I help investigators understand the technical aspects of the fraud, like how the attackers gained access or manipulated the system. A recent case involved a sophisticated business email compromise (BEC) scheme where fraudulent ACH payments were made to accounts controlled by the perpetrators. My involvement included providing the forensic timeline of events, helping to reconstruct the attacker’s actions and trace the funds. We worked closely to gather evidence and build a successful case, leading to the arrest and prosecution of the individuals responsible. Maintaining confidentiality and following proper legal procedures is paramount in these collaborations.

Effective communication and clear documentation are crucial during these investigations. Think of it as a puzzle; we provide the pieces, and law enforcement puts the puzzle together.

False positives, where legitimate transactions are flagged as fraudulent, are a major challenge in ACH fraud detection. We use a multi-layered approach to minimize them. Firstly, we continuously refine our fraud detection models, using machine learning algorithms that adapt to evolving fraud patterns. This involves regular model retraining using both historical and new data. Secondly, we implement a robust review process. Alerts are prioritized based on risk scores, with the highest-risk alerts reviewed by trained analysts who verify the validity of the flag. If a false positive is identified, we analyze the reasons behind it to improve our model’s accuracy. Finally, we provide clear and concise explanations to users regarding why a transaction was flagged, enhancing trust and reducing disruption.

Imagine a security system with too many sensors; it’s going to trigger alarms for everything. Our goal is to fine-tune the system to accurately identify genuine threats while minimizing unnecessary disruptions.

Current ACH fraud detection technologies, while effective to a degree, have limitations. One key challenge is the evolving nature of fraud schemes. Attackers are constantly adapting their tactics, making it difficult for static rule-based systems to keep pace. Another limitation is the reliance on historical data. Novel fraud schemes that haven’t been previously observed may slip through the cracks. Furthermore, the lack of real-time transaction monitoring in some cases creates a delay in identifying and mitigating fraud. Finally, the sheer volume of transactions processed daily makes it computationally intensive and challenging to analyze every single transaction in real-time with high accuracy.

Think of it as an arms race; as soon as we develop a defense, the attackers find a way to circumvent it. This constant evolution necessitates ongoing improvements and adaptations to our detection systems.

Prioritizing ACH fraud alerts is a critical aspect of effective fraud management. We use a risk-scoring system that takes into account several factors, including the transaction amount, the sender’s history, the beneficiary’s reputation, and the presence of any suspicious patterns or anomalies. Alerts with higher risk scores are prioritized for immediate investigation. For example, a large, unexpected transaction from a new customer to an unfamiliar account would receive a high priority, while a small transaction from a long-standing customer with a clean history might be placed lower on the queue. Additionally, we consider factors such as the type of payment (e.g., CCD vs. PPD) and any associated metadata. This layered approach ensures that resources are focused on the most critical threats first.

It’s like triage in a hospital; you address the most critical patients first. Similarly, we prioritize the most concerning fraud alerts to minimize losses.

My experience encompasses various ACH payment types, each with unique vulnerabilities. CCD (Credit entries) payments, for example, are relatively less prone to fraud due to their nature as push payments from the originator. However, they can still be targets for BEC schemes or if the originator’s system is compromised. PPD (Prearranged payment) payments, common for recurring bill payments, are vulnerable to account takeover fraud, where attackers gain access to customer accounts to alter payment details. WEB (Web Debit) payments, utilized for online transactions, are susceptible to phishing attacks and malware infections that steal customer credentials. Understanding these vulnerabilities allows us to tailor our detection strategies. For instance, for PPD payments, we might focus on detecting changes in payment amounts or beneficiary details that deviate from established patterns.

Different payment types present unique attack vectors, much like different locks require different keys to open them. We need specific strategies to secure each type of payment.

Preventing ACH fraud requires collaboration across various departments. I work closely with the IT department to ensure system security and monitor network traffic for suspicious activity. With the compliance department, I ensure adherence to industry regulations and best practices, maintaining secure and auditable processes. The customer service team is crucial in identifying and addressing potential fraud indicators reported by customers. Collaboration with the finance department allows us to quickly investigate fraudulent transactions and initiate chargebacks. Finally, regular communication and information sharing across all departments are critical for a cohesive and effective fraud prevention strategy. This cross-functional approach builds a comprehensive defense system.

Think of it as a team sport; effective fraud prevention requires coordinated efforts from different players to achieve a common goal.

Strong internal controls are the bedrock of a robust ACH fraud prevention program. Think of them as the multiple locks on a high-security door – each layer adds a significant hurdle for fraudsters to overcome. Without these controls, your organization is vulnerable to a wide range of attacks, from simple employee errors to sophisticated schemes.

• Segregation of Duties: No single individual should have complete control over the entire ACH process. This prevents one person from initiating, authorizing, and processing transactions, minimizing the opportunity for fraud. For example, one person authorizes payments, another initiates them through the ACH system, and a third person reconciles the accounts.
• Access Controls: Strict access controls limit who can initiate ACH transactions or access sensitive financial data. This often involves multi-factor authentication (MFA), strong passwords, and regular password changes. Imagine a situation where only authorized personnel with unique logins and MFA can access the ACH system – this prevents unauthorized access.
• Regular Audits and Reconciliation: Regular internal audits and reconciliation of ACH transactions are crucial for detecting discrepancies and anomalies. This is like a regular health check for your financial system; early detection of issues enables prompt corrective actions. These audits should include a comparison of internal records with bank statements.
• Employee Training: Thorough employee training on ACH fraud awareness and prevention best practices is essential. Regular refresher courses are also needed to stay updated on emerging threats and techniques. Training should cover phishing, social engineering, and internal control weaknesses.
• Regular Review of Vendor Relationships: Periodically review the security practices of your vendors who handle your ACH transactions. This ensures that your organization isn’t indirectly exposed to vulnerabilities within their systems.

Implementing these controls proactively minimizes vulnerabilities and significantly reduces the likelihood of successful ACH fraud attempts. Ignoring them invites disaster.

My experience with forensic accounting techniques in ACH fraud investigations is extensive. It often involves meticulous data analysis, tracing the flow of funds, and reconstructing transactions to pinpoint the source and method of the fraud. I’ve utilized various techniques, including:

• Data Analytics: Using specialized software to analyze large datasets of ACH transactions, identifying unusual patterns, outliers, and anomalies that might indicate fraudulent activity. For example, detecting unusually high transaction volumes from a specific account or to an unusual beneficiary.
• Transaction Tracing: Following the trail of funds through multiple accounts and financial institutions to identify the ultimate recipient of the fraudulent payments and potentially uncovering other related crimes.
• Document Review: Scrutinizing internal documents, such as payment authorizations, bank statements, and email communications, to corroborate transaction data and identify potential perpetrators. Examining the communication logs could reveal if there was any suspicious communication prior to the fraudulent transaction.
• Interviewing Witnesses: Conducting interviews with employees, clients, and other relevant individuals to gather information and corroborate findings from data analysis and document review. Gathering firsthand accounts of suspicious activities is critical.

In one particular case, I used data analytics to identify a pattern of ACH debits originating from a specific department, leading to the discovery of an employee manipulating the system for personal gain. By carefully tracing the funds, we were able to recover a significant portion of the stolen money.

Ensuring accuracy and completeness in ACH fraud investigations requires a rigorous, multi-faceted approach. Think of it like solving a complex puzzle; every piece is crucial. We utilize the following steps:

• Establish a Clear Scope and Methodology: Define the specific objectives, timeline, and methodology for the investigation upfront. This provides a roadmap and keeps the investigation focused.
• Secure and Preserve Evidence: Properly secure and preserve all relevant electronic and physical evidence to ensure its admissibility in any legal proceedings. This could involve securing computer systems, capturing network traffic logs, and obtaining relevant bank statements.
• Chain of Custody: Maintain a meticulous chain of custody for all collected evidence to ensure its integrity. This is critical for legal admissibility.
• Data Validation and Reconciliation: Verify the accuracy and consistency of data obtained from various sources. This involves cross-checking information from multiple databases, bank statements, and internal records.
• Independent Verification: Whenever possible, have multiple investigators review findings and conclusions to minimize bias and ensure objectivity. This provides a layer of quality control.
• Documentation: Maintain detailed and comprehensive documentation throughout the investigation process. This provides a complete record for review and potential legal proceedings.

Through meticulous attention to detail at every stage, we maintain a high level of confidence in the accuracy and completeness of our investigations.

Reporting ACH fraud to regulatory bodies is a critical aspect of our responsibility. This process typically involves adhering to strict reporting deadlines and providing comprehensive documentation. The specific regulatory bodies and reporting requirements vary depending on the jurisdiction and the nature of the fraud. However, generally this involves:

• Identifying the Relevant Regulatory Bodies: Determining which regulatory bodies need to be notified, such as the Financial Crimes Enforcement Network (FinCEN) in the US, or equivalent agencies in other countries.
• Gathering Required Information: Compiling all necessary information, including details about the fraud, the affected accounts, the amount of losses, and any identified perpetrators. This might include detailed transaction logs and internal audit findings.
• Preparing and Filing the Report: Preparing the report according to the specific requirements of the regulatory body and submitting it within the prescribed deadlines. These reports typically adhere to specific formats and often require extensive detail.
• Follow-up and Cooperation: Cooperating fully with the regulatory body during the investigation and providing any additional information they may request. This often involves providing testimony and cooperating with their investigations.

Timely and accurate reporting is not only a legal requirement but also crucial for helping to prevent future instances of fraud and protecting the financial system.

Managing the workload of an ACH fraud investigation team requires careful planning and prioritization. We leverage several strategies:

• Prioritization Matrix: We use a prioritization matrix to rank cases based on factors like the amount of potential loss, the complexity of the fraud, and the urgency of the situation. This ensures that the most critical cases are addressed first.
• Case Management System: We utilize a case management system to track the progress of each investigation, assign tasks to team members, and monitor deadlines. This provides a centralized repository for all case-related information.
• Workload Balancing: We regularly review the workload of each team member and adjust assignments to ensure a fair and manageable distribution of tasks. This minimizes burnout and maximizes productivity.
• Specialized Roles and Skills: We have team members with specialized skills in areas like data analysis, forensic accounting, and legal compliance. This ensures that each case receives the appropriate level of expertise.
• Regular Team Meetings: We hold regular team meetings to discuss ongoing investigations, share best practices, and identify any potential bottlenecks or challenges. This facilitates effective collaboration.

By proactively managing workload, fostering collaboration, and leveraging technology, we ensure efficient and effective investigations without compromising quality.

Measuring the effectiveness of our ACH fraud prevention program relies on a combination of quantitative and qualitative metrics. We track:

• Number of Fraudulent Transactions: This is a straightforward measure of the success of our preventative measures. A decrease in this number indicates a successful program.
• Amount of Losses from Fraud: Tracking the total financial loss from successful fraud attempts. A reduction in losses indicates improvements in prevention efforts.
• Time to Detect Fraud: Measuring the time it takes to identify and respond to fraudulent activity. A shorter detection time minimizes potential losses.
• Mean Time to Resolution (MTTR): The average time taken to resolve a fraud case after detection. Efficient resolution minimizes disruption.
• False Positives: Tracking the number of false positives generated by our detection systems. This helps refine the system to minimize interruptions and increase efficiency.
• Employee Training Completion Rates: Monitoring employee participation and completion of fraud awareness training programs. This demonstrates the effectiveness of the training initiatives.

By continuously monitoring and analyzing these metrics, we can identify areas for improvement and refine our program to enhance its effectiveness. It’s an iterative process, continually adapting to evolving threats.

Machine learning (ML) significantly enhances ACH fraud detection capabilities. Traditional rule-based systems struggle to keep pace with sophisticated fraud schemes. ML algorithms, on the other hand, can identify complex patterns and anomalies that humans might miss.

• Anomaly Detection: ML algorithms can analyze massive datasets of transaction data, identifying unusual patterns and deviations from established norms that may indicate fraudulent activity. This is especially effective in detecting new or evolving fraud schemes.
• Predictive Modeling: ML models can predict the likelihood of fraudulent transactions based on historical data and various features. This allows for proactive interventions, preventing fraud before it occurs.
• Real-time Fraud Detection: ML algorithms can be integrated into real-time transaction monitoring systems, flagging potentially fraudulent transactions immediately for review. This allows for rapid response and minimized financial losses.
• Automated Investigation: ML can automate certain aspects of the investigation process, such as data analysis and pattern recognition, freeing up investigators to focus on more complex cases. This increases efficiency.

For example, an ML model might identify a suspicious transaction based on factors like the transaction amount, the time of day, the recipient’s location, and the history of the sender’s account. This kind of sophisticated analysis is beyond the capabilities of manual review.
