Resumen

Abstract Fraud presents a serious problem and arising issue for all of society at national and global levels. According to global fraud research conducted by the Association of Certified Fraud Examiners, it is estimated that the average company loses about 5% of its annual revenue due to different types of business fraud. Total estimated annual fraud losses according to global ACFE research reaches about 4.7 trillion dollars. Business frauds also present an important issue for the Croatian economy, business community and society as a whole. Thereby, considerable attention should be given to this issue with the aim of raising awareness throughout society on fraud and its negative and destructive impact on all of society. The main purpose of this paper is to examine differences in fraud characteristics between state-owned and private companies in the Republic of Croatia. Research was based on data on business frauds obtained by the Association of Certified Fraud Examiners Croatia which included 124 respondents. Data were related to frauds that occurred in Croatian companies in 2021 and 2020. In this paper we focused on fraud characteristics such as fraud loss, type of fraud, fraud duration and methods of fraud detection in order to determine whether fraud in privately owned companies differs significantly from fraud in state-owned companies. Research results revealed how differences in fraud characteristics among privately and state-owned companies exist. Based on a sample of Croatian companies that were victims of fraud, it is noted how fraud in state-owned companies lasts longer and creates greater loses in comparison to fraud in private owned companies. Moreover, data related to estimated fraud loss and fraud duration were statistically significant in terms of differentiating these two groups of companies. Based on data on discriminatory variables a logistic regression model correctly classified 78.46% of companies in the group of companies that are privately or state-owned.

Resumen

Prevention of fraud (fraudi) is an act or an effort to prevent or detain a person from not doing an act of fraud which is found to be detrimental. This study aims to determine the effect of competence in human resources, whistleblowingi systemi and individual morality in the face of preventive fraud (fraudi) in managing the financial management of Desai in Desai in Klungkung District. This research was conducted in all Desai offices in Klungkung District. With a total sample of 87 Desai apparatus, the sampling method used was purposive sampling. Data analysis techniques used in this research are Descriptive Statistics, Validity Test, Reliability Test, Classical Assumption Test, Multiple Linear Regression, Determination Coefficient, F Test and T Test. The results of the study show that the competence of human resources does not affect the prevention of fraud (fraudi). Whistleblowingi systemi positively influences the prevention of fraud (fraudi). Individual morality has a positive effect on preventing fraud (fraudi).

Resumen

This paper provides insight into financial statement fraud instances investigated during the late 1980s through the 1990s within three volatile industries—technology, health care, and financial services—and highlights important corporate governance differences between fraud companies and no-fraud benchmarks on an industry-by-industry basis. The fraud techniques used vary substantially across industries, with revenue frauds most common in technology companies and asset frauds and misappropriations most common in financial-services firms. For each of these three industries, the sample fraud companies have very weak governance mechanisms relative to no-fraud industry benchmarks. Consistent with prior research, the fraud companies in the technology and financial-services industries have fewer audit committees, while fraud companies in all three industries have less independent audit committees and less independent boards. In addition, this study provides initial evidence that the fraud companies in the technology and health-care industries have fewer audit committee meetings, and fraud companies in all three industries have less internal audit support. This study of more current financial statement fraud instances contributes by updating our understanding of fraud techniques and risk factors in three key industries. Auditors should consider the industry context as they evaluate the risk of financial fraud, and they should compare clients' governance mechanisms to relevant no-fraud industry benchmarks.

Resumen

With the extensive use of credit cards, fraud appears as a major issue in the credit card business. It is hard to have some figures on the impact of fraud, since companies and banks do not like to disclose the amount of losses due to frauds. At the same time, public data are scarcely available for confidentiality issues, leaving unanswered many questions about what is the best strategy. Another problem in credit-card fraud loss estimation is that we can measure the loss of only those frauds that have been detected, and it is not possible to assess the size of unreported/undetected frauds. Fraud patterns are changing rapidly where fraud detection needs to be re-evaluated from a reactive to a proactive approach. In recent years, machine learning has gained lot of popularity in image analysis, natural language processing and speech recognition. In this regard, implementation of efficient fraud detection algorithms using machine-learning techniques is key for reducing these losses, and to assist fraud investigators. In this paper logistic regression, based machine learning approach is utilized to detect credit card fraud. The results show logistic regression based approaches outperforms with the highest accuracy and it can be effectively used for fraud investigators.

Resumen

ABSTRACT This study uses survey data gathered by the Association of Certified Fraud Examiners (ACFE) and provided to the Institute for Fraud Prevention (IFP) to examine differences in the profile of financial reporting fraud (FRF) between private companies and public companies. Although private companies represent a significant portion of the economy, largely due to lack of data on these companies, most research on FRF examines only public companies. The primary objective of this study is to determine how private company FRF is different from FRF in public companies. Our multivariate tests reveal that public companies have stronger anti-fraud environments, are more likely to have frauds that involve timing differences, tend to experience larger frauds, have frauds that involve a larger number of perpetrators, and are less likely to have frauds that are discovered by accident. Overall, it appears that the stronger anti-fraud environment in public companies leads public company FRF perpetrators to use less obvious fraud methods (i.e., timing differences) and to involve larger fraud teams to circumvent the controls. These public company frauds are larger than in private companies, and their larger size may make them more likely to be detected through formal means, rather than by accident. Based on the results, we encourage auditors and others to be particularly attuned to the unique risks of the public versus private setting.

Resumen

This paper uses data collected for an MA Thesis on Security Managers’ perspectives on challenges facing Commercial Banks in Preventing Frauds in Nairobi County, Kenya. The study was motivated by continued rise of frauds in commercial banks in the county, despite the extensive mitigation measures put in place to deter frauds. The study established the nature of frauds prevalent in Kenya commercial banks in Nairobi County, assessed the determinants of fraud in Kenya commercial banks, determined Bank Security Managers Capacity in fraud prevention, and finally examined Security Managers perceptions on the relationship between the existing preventive measures and emerging Bank fraud trends in Nairobi County, Kenya. The study was grounded by the Fraud Triangle concept and adopted a case study qualitative design. The main method of data collection was the interview. The study comprises of 50 respondents: 39 main respondents and 11 Key Informants. The census sampling Method was used to select respondents for the study. Data was transcribed and the transcriptions coded using NVIVO software. The study established three major types of frauds; Management frauds, Non-Management Frauds and Third Party Frauds, all said to be on an increase trend. According to this study fraud rates are higher at Nairobi County (90%), than at other counties (70%). Mobile and Internet banking frauds were found to be the new threats challenging commercial banks because by their very nature because of technological sophistication, were committed from geographical location including outside the country. The study established two major determinants of frauds; Fraudsters Perspectives and institutional related factors. Major fraudster’s perspectives include; condition under which people can rationalize their prospective crimes, opportunities to commit crimes, perceived suitability of targets for fraud, technical ability of the fraudster, the possibility and likelihood of the fraud being discovered and the nature of consequences. Institutional factors that influence fraud prevalence include; weak accounting and control systems, and ineffective internal audits. According to the study, technological sophistication has outsmarted many security managers in the banking sector, because of their technological skills gaps in Fraud forensics. Finally, the study established the relationship between existing preventive measures and emerging Bank fraud trends in Nairobi County. Major policy recommendations suggested to cut frauds at the nib include; benchmarking for best internationally recognized standards such as carrying out expected and unexpected audits, enforced internal controls, regular training of security managers, and review of commercial banks organogram that will place security managers at a position to police frauds perpetrated by management.

Resumen

Asia Pacific is the region with the highest number of losses in the world. While Indonesia ranks fourth in the number of frauds, it has the highest increase in frauds based on the CPI index. This study aims to examine employee fraud triggered by the six components of the fraud hexagon. This study tries to develop the hexagon fraud element by adding power distance elements and using ethical values as a moderating variable. This study conducted a survey of 351 respondents. Using a purposive sampling method, the heads of funds, heads of credit, heads of treasurers and heads of accountants were selected as respondents in 128 rural banks in Bali. PLS displays an adjusted R2 value of 0.331. Not all elements of the fraud hexagon are proven to influence fraud. Only pressure, opportunity, rationalization, and ego affect employees in committing fraud. Meanwhile, power distance as an additional element of the fraud hexagon can increase fraud. Ethical values can become an anti-fraud strategy in reducing employee pressure and ego in committing fraud. The results of this study will provide input for rural bank managers to anticipate factors that increase employee fraud and increase the role of ethical values in suppressing employees’ desire to commit fraud.

Resumen

La presente investigación busca entender la importancia de la aplicación de la Auditoría Forense como herramienta de apoyo en empresas del sector transporte. Para tal fin se analizó conceptos, métodos y herramientas que son utilizados para la reducción del fraude financiero y tributario, además se revisaron los conceptos de Control, Fraude Financiero y Tributario del sector de transporte de carga terrestre. Para el plan de investigación, se plantea la hipótesis del Impacto de la Auditoría Forense como herramienta de apoyo, para detectar y reducir el fraude financiero y tributario en las empresas del sector transporte. Dicha hipótesis alternativa es rechazada con un 5% de significancia. En la metodología de investigación, se ejecutó un estudio de tipo documental, el cual fue llevado a cabo por entrevistas a tres expertos del tema. Para ello, se elaboró un cuestionario con el propósito de identificar si se tenía conocimiento sobre Auditoría Forense, y conocer sobre los procesos de control con los que cuentan las empresas del rubro. Como resultado de la aplicación del instrumento cualitativo y cuantitativo, se puede establecer que mediante la aplicación de la Auditoría Forense como herramienta de apoyo se logra detectar y prevenir fraudes. De esta forma, se demuestra que la Auditoría Forense brinda ventajas y que al implementarla como herramienta de apoyo se obtienen grandes resultados. Luego del respectivo análisis de interpretación de los resultados de dicha investigación, se puede concluir que la aplicación de la Auditoría Forense como herramienta de apoyo no reducirá los casos de robos y fraude intencionales: a mayor control en los procesos se disminuirá las posibilidades de cometer fraude y se incrementará un mayor control en las áreas más sensibles del rubro.
This research seeks to understand the importance of the application of Forensic Audit as a support tool in companies in the transport sector. For this purpose, concepts, methods and tools that are used for the reduction of financial and tax fraud were analyzed, and the concepts of Control, Financial and Tax Fraud of the land freight transport sector were also reviewed. For the research plan, the hypothesis of the Impact of Forensic Audit is presented as a support tool, to detect and reduce financial and tax fraud in companies in the transport sector. This alternative hypothesis is rejected with a 5% significance. In the research methodology, a documentary study was executed, which was carried out by interviews with three experts on the subject. For this, a questionnaire was prepared with the purpose of identifying if there was knowledge about Forensic Audit, and knowing about the control processes that the companies in the field have. As a result of the application of the qualitative and quantitative instrument, it can be established that through the application of Forensic Audit as a tool to support internal auditing, fraud can be detected and prevented. In this way, it is demonstrated that Forensic Audit offers advantages and that when implementing it as a support tool, great results are obtained. After the respective analysis of interpretation of the results of said investigation, it can be concluded that the application of Forensic Audit as a support tool will not reduce cases of intentional theft and fraud: greater control in the processes will reduce the chances of committing fraud and greater control will be increased in the most sensitive areas of the item.

Resumen

This paper uses statistical learning to examine and compare three different statistical methods with the aim to predict credit card fraud. The methods compared are Logistic Regression, K-Nearest Neighbour and Random Forest. They are applied and estimated on a data set consisting of nearly 300,000 credit card transactions to determine their performance using classification of fraud as the outcome variable. The three models all have different properties and advantages. The K-NN model preformed the best in this paper but has some disadvantages, since it does not explain the data but rather predict the outcome accurately. Random Forest explains the variables but performs less precise. The Logistic Regression model seems to be unfit for this specific data set.

Resumen

This thesis investigates fraud and the situation on Internet with e-commerce today, to point on some potential threats and needed countermeasures. The work reviews several state of the art e-fraud schemes, techniques used in the schemes and statistics on the extent of e-fraud. This part shows that e-frauds are today both sophisticated and widespread.

Since real world frauds are deemed impossible to fully cover in order to predict potential new e-frauds, the thesis adopts a different approach. It suggests two abstraction models for fraud cases, a protocol model and a functional model. These are used to perform analysis on case studies on both telecom frauds and e-frauds. The analysis presents characteristics for both types of frauds. Using one of the abstraction models, the functional model, conceptually similar cases among telecom frauds as well as e-fraud cases are identified. The similar cases in each category are then compared, using the other abstraction model, the protocol model. The study shows that concepts from telecom frauds already exist in e-frauds.

Several challenges and some possibilities in e-fraud prevention and detection are also extracted in the comparative study of the different categories. The major consequence of the challenges is e-frauds’ higher scalability compared to telecom frauds.

Finally, this thesis covers several existing countermeasures in e-commerce along with specific countermeasures against auction fraud, phishing and spam. However, it is shown that these countermeasures do not address the challenges in e-fraud prevention and detection to a satisfactory extent. Therefore, this thesis proposes several high-level countermeasures in order to address the challenges.

Segundo a Teoria do Triângulo da Fraude, para ocorrer um comportamento fraudulento é necessário combinar "incentivo", "oportunidade" e "racionalização". Este estudo teve como finalidade averiguar a postura dos administradores e directores financeiros perante a fraude, abordando apenas o lado do incentivo. O presente estudo teve como base um inquérito enviado para administradores e directores financeiros de Sociedades Anónimas Portuguesas. No estudo foram analisadas variáveis sociodemográficas (género, idade, nível de habilitação, posse de habilitação académica na área financeira, estado civil) e variáveis organizacionais (número de trabalhadores da organização, tratar-se de uma empresa familiar ou estar incluída num grupo económico, assim como o sector de actividade em que está inserida). Os resultados obtidos mostram que não existe um perfil específico de modo a uma pessoa se sentir incentivada para cometer fraude.
According to the theory of the Fraud Triangle, for a fraudulent behaviour to occur it is needed to combine "incentive", "opportunity" and "rationalization". This study had the goal to find out how the administrators and financial directors react when confronted by fraud, approaching only the incentive side. The present study was based on an enquire sent to administrators and financial directors of Anonymous Portuguese Societies. In this study were analysed sociodemographic variables (gender, age, qualification level, possession of financial related academic qualification, civil status) and organizational variables (number of workers in the organization, being a family business or to be included in an economic group, as well as the activity sector it is part of). The results showed there is not a specific profile that incentives a person to commit fraud.

O transporte marítimo de mercadorias é uma actividade abrangentemente regulada por via do direito marítimo, pelo que, a compreensão da natureza jurídica do navio ou o estudo do alcance que determinados documentos comportam, como o conhecimento de embarque (Bill of Lading), são aspectos necessários ao entendimento das particularidades da fraude marítima. A par da complexidade legal e documental intrínsecas às actividades de transporte marítimo de mercadorias, aspectos como o seu carácter internacional e o elevado número de agentes que intervêm no sector, são vistos como factores críticos à ocorrência de fraudes na esfera do transporte marítimo. Com base neste enquadramento, a investigação conclui que a tecnologia Blockchain, enquanto uma DLT - Distributed Ledger Technology, especialmente por via da resolução da problemática do double spending sem recurso a uma entidade centralizadora, e uma vez ultrapassados os desafios de adopção generalizada da tecnologia, pode vir a mitigar ou mesmo resolver grande parte da problemática da fraude marítima tal qual se conhece, especialmente a de carácter documental.
It is estimated that maritime fraud - fraud involving ships and / or cargo transported by sea - is currently causing losses up to several billion US dollars annually. Maritime freight is an activity that is broadly regulated through maritime law, so understanding the legal nature of the ship or examining the scope of certain documents, such as the Bill of Lading, is necessary to comprehend the maritime fraud. In addition to the legal and documentary complexity inherent in maritime freight transport activities, aspects such as its international character and the large number of agents involved in the sector are seen as critical factors for the occurrence of maritime fraud. Based on this framework, the research concluded that Blockchain technology, while DLT - Distributed Ledger Technology, especially by solving the problem of double spending without recourse to a centralization entity, and once overcome the challenges of general adoption of the technology, can mitigate or even solve much of the problems of maritime fraud as it is known, especially those involving documents.

Resumen

Segundo relatório da auditoria KPMG, 69% das empresas admitiram ser vítimas de algum tipo de fraude. Em 2010, no setor bancário foram perdidos aproximadamente R$ 1,5 bilhões devido às fraudes financeiras cometidas em clientes considerando apenas as fraudes documentais e as perdas com fraudes bancárias eletrônicas superaram os 900 milhões neste mesmo ano. Os tipos de fraudes cometidas foram diversos, dentre eles a fraude durante a abertura de contas, cheques clonados, falsificação de documentos, alterações de códigos de barras e clonagem de cartões. A fraude é um problema frequente nas organizações e bastante discutido no mercado, porém verificou-se a existência de uma lacuna teórica quando se trata de gestão da fraude externa. O objetivo do trabalho foi a estruturação de um quadro conceitual para a Gestão da Fraude Financeira e a sua comparação com a prática.Este é um estudo qualitativo exploratório e foi realizado por meio da análise baseada na Teoria Fundamentada definindo categorias a partir da literatura disponível e a sua comparação com entrevistas feitas em um banco de varejo brasileiro e uma associação de instituições financeiras, além dos artigos jornalísticos. Com relação à utilização dos resultados esta é uma pesquisa aplicada já que seu resultado pode, além de contribuir para a discussão teórica, ser aplicada em qualquer organização interessada em gerir a fraude financeira. Os resultados da elaboração do quadro conceitual mostram que a gestão da fraude financeira externa tem quatro fases: a Contínua, a Prevenção, Detecção e a Reação e as categorias definidas estão inseridas nelas. Quanto à comparação da teoria com a prática, nem todos os aspectos verificados na literatura puderam ser encontrados nos relatos das entrevistas e nos artigos jornalísticos analisados.
According to KPMG audit report, 69% of companies admitted being victims of some kind of fraud. In 2010, the banking sector have lost approximately R$ 1.5 billion due to financial fraud perpetrated on customers considering only documentary fraud and the electronic banking fraud losses exceeded R$ 900 million in the same year. The types of fraud were many, including fraud during account opening, cloned checks, forgery, alteration barcode and card cloning. Fraud is a common problem in organizations and widely discussed in the market, however it was found that there is a theoretical gap when it comes to managing external fraud. The objective of this research was to structure a conceptual framework for the Management of Fraud and its comparison with the practice. This is an exploratory qualitative study and was conducted through analysis based on Grounded Theory defining categories from the available literature and interviews with comparison to a bank and an association of financial institutions, in addition to news articles. Regarding the use of results is an applied research its result can also contribute to the theoretical discussion, and be applied to any organization interested in managing financial fraud. The results of the development of the conceptual framework shows that the management of external financial fraud has four phases: Continuous, Prevention, Detection and Reaction and the defined categories are located in them. Regarding the comparison of theory with practice, not all aspects verified in the literature could be found in the reports of interviews and newspaper articles analyzed.

Resumen

The anonymity of online networks makes tackling fraud increasingly costly. Thanks to the superiority of graph representation learning, graph-based fraud detection has made significant progress in recent years. However, upgrading fraudulent strategies produces more advanced and difficult scams. One common strategy is synergistic camouflage —— combining multiple means to deceive others. Existing methods mostly investigate the differences between relations on individual frauds, that neglect the correlation among multi-relation fraudulent behaviors. In this paper, we design several statistics to validate the existence of synergistic camouflage of fraudsters by exploring the correlation among multi-relation interactions. From the perspective of multi-relation, we find two distinctive features of fraudulent behaviors, i.e., alienation and marginalization. Based on the finding, we propose COFRAUD, a correlation-aware fraud detection model, which innovatively incorporates synergistic camouflage into fraud detection. It captures the correlation among multi-relation fraudulent behaviors. Experimental results on two public datasets demonstrate that COFRAUD achieves significant improvements over state-of-the-art methods.

Resumen

In the present monetary situation, credit card use has gotten normal. These cards allow the user to make payments online and even in person. Online payments are very convenient, but it comes with its own risk of fraud. With the expanding number of credit card users, frauds are also expanding at the same rate. Some machine learning algorithms can be applied to tackle this problem. In this paper an evaluation of supervised and unsupervised machine learning algorithms has been presented for credit card fraud detection.

Resumen

Credit card transaction fraud costs billions of dollars to card issuers every year. Besides, the credit card transaction dataset is very skewed, there are much fewer samples of frauds than legitimate transactions. Due to the data security and privacy, different banks are usually not allowed to share their transaction datasets. These problems make traditional model difficult to learn the patterns of frauds and also difficult to detect them. In this paper, we introduce a novel framework termed as federated meta-learning for fraud detection. Different from the traditional technologies trained with data centralized in the cloud, our model enables banks to learn fraud detection model with the training data distributed on their own local database. A shared whole model is constructed by aggregating locallycomputed updates of fraud detection model. Banks can collectively reap the benefits of shared model without sharing the dataset and protect the sensitive information of cardholders. To achieve the good performance of classification, we further formulate an improved triplet-like metric learning, and design a novel meta-learning-based classifier, which allows joint comparison with K negative samples in each mini-batch. Experimental results demonstrate that the proposed approach achieves significantly higher performance compared with the other state-of-the-art approaches.

Resumen

As a matter of fact, it is usually taken for granted that the occurrence of unauthorized behaviors is necessary for the fraud detection in online payment services. However, we seek to break this stereotype in this work. We strive to design an ex-ante anti-fraud method that can work before unauthorized behaviors occur. The feasibility of our solution is supported by the cooperation of a characteristic and a finding in online payment fraud scenarios: The well-recognized characteristic is that online payment frauds are mostly caused by account compromise. Our finding is that account theft is indeed predictable based on users' high-risk behaviors, without relying on the behaviors of thieves. Accordingly, we propose an account risk prediction scheme to realize the ex-ante fraud detection. It takes in an account's historical transaction sequence, and outputs its risk score. The risk score is then used as an early evidence of whether a new transaction is fraudulent or not, before the occurrence of the new transaction. We examine our method on a real-world B2C transaction dataset from a commercial bank. Experimental results show that the ex-ante detection method can prevent more than 80\% of the fraudulent transactions before they actually occur. When the proposed method is combined with an interim detection to form a real-time anti-fraud system, it can detect more than 94\% of fraudulent transactions while maintaining a very low false alarm rate (less than 0.1\%).

Resumen

In this paper, we argue that setting up a new Digital Public Infrastructure - a National Fraud Portal (NFP) - is the only way to address fraud and consumer scams efficiently. NFPs provide a technological solution as a shared facility for banks, law enforcement, the Financial Intelligence Unit (FIU), the central bank, the conduct supervisor, and other stakeholders. Further down the line, NFPs can connect to one another as cross-border criminal activity increases (a likely consequence of suppressing fraud domestically). The National Fraud Portal (NFP) enables: The real-time tracing and tracking of fund movements across the banking system that allow banks to recover funds for victims quickly The validation and prioritization of cases across the economy using data-driven models The faster identification of new mule accounts at a reduced cost More accurate methods for fraud detection and risk scoring that employ Graph AI deployed on network data. The real-time provision of risk scores and features to banks via APIs, allowing them to improve their fraud models and make faster, more accurate decisions about preventing fraudulent payments before settlement. In this paper, we detail the technological components of the National Fraud Portal. The paper is a result of FNA’s work building technology for National Fraud Portals in Southeast Asia, as well as conversations with over 100 institutions across 20 countries that are actively working on, or have an interest in tackling the problem of fraud and scams.

Resumen

This study was undertaken to guide the FSA and the National Food Crime Unit (NFCU) on the development of future strategies and operational activities to improve food fraud prevention. Its aims were to: (1) Investigate successful initiatives and strategies for fraud prevention and especially food fraud prevention; (2) understand what has worked well in preventing commodity-based fraud (including food fraud) and the lessons learned from these initiatives and strategies; (3) provide recommendations which could be adopted by the NFCU and incorporated into the unit’s key strategies; and (4) provide recommendations for any future research required within this area. The key research questions which underpinned these objectives were: (1) What food fraud prevention strategies and initiatives have been implemented in the UK and other countries? (2) What strategies and initiatives have been implemented to prevent and tackle commodity-based fraud in other industries? (3) What conditions need to be in place to enable fraud prevention strategies to be successful?
