The internet has made the world more linked than ever before. While taking advantage of this online transition, cybercriminals target flaws in online systems, networks, and infrastructure. Businesses, government organizations, people, and communities all across the world, particularly in African countries, are all severely impacted on an economic and social level. Many African countries focused more on developing secure electricity and internet networks; yet, cybersecurity usually receives less attention than it should. One of Africa's major issues is the lack of (...) adequate digital security infrastructure, which has harmed businesses, governmental institutions, and individual communities more than it has helped. The majority of African countries operate without cybersecurity measures in place to combat cyberattacks. Only a few examples of today's cyber risks include digital extortion, business email intrusion, data breaches, online fraud, ransomware, and phishing, and new types of cybercrime are always developing. Due to the advent of new technology, cybercriminals have become more organized and quicker in their attacks and alliance creation. To maintain a secure digital environment for all internet users, this study focused on the challenges, solutions, and need for African countries to improve their online safety by tackling cybercrime, online fraud, and cybersecurity concerns. The objective of this study is to offer practical and long-term answers to the problems posed by cybercrime, with a continuing emphasis on enhancing online safety. It will assess the effectiveness of cutting-edge cybersecurity measures, legislative frameworks, and cross-border cooperative efforts, as well as potential areas for improvement. Additionally, the study will examine cutting-edge methods like blockchain technology, machine learning, and other cutting-edge methods that could improve our using digital defences to stop cybercrime.

This thesis, which is based on six peer-reviewed publications, is a theoretical and qualitative treatment of the ways in which social and contextual factors serve as a resource for understanding the particularities of ‘cybercrime’ that emanates from Nigeria. The thesis illuminates how closer attention to Nigerian society aids the understanding of Nigerian cybercriminals (known as Yahoo Boys), their actions and what constitutes ‘cybercrime’ in a Nigerian context. ‘Cybercrime’ is used in everyday parlance as a simple acronym for (...) all forms of crimes on the internet, whereas ‘cybercrime’ in a Nigerian context is rooted in socioeconomics and determined by it. In particular, the defrauding of victims for monetary benefit is the most significant theme that emerged from the analysis of Yahoo Boys. While all six publications are situated at the intersections of multiple fields of study, they all share a common endorsement of the constructionist/interpretivist position. The six published works comprise: [a] three conceptual publications; and [b] three empirical publications. The conceptual publications deconstruct the meanings of multiple taken-for-granted concepts in cybercrime scholarship and develop more robust conceptual lenses, namely: (1) ‘Digital Spiritualization’; (2) ‘The Tripartite Cybercrime Framework – TCF’; and (3) ‘The Synergy between Feminist Criminology and the TCF’. These new conceptual lenses represent the candidate’s contribution to developing theory in the field. Alongside this, the empirical section includes three sets of qualitative data, which include: (1) interviews with seventeen Nigerian parents; (2) lyrics from eighteen Nigerian musicians; and (3) interviews with forty Nigerian law enforcement officers. These diverse sources of qualitative data provide a more fully-developed understanding of ‘cybercrime’ in the Nigerian context (and elsewhere). All six-published works, while individually contributing to knowledge, collectively shed clearer light on the centrality of cultural context in the explanation of ‘cybercrime’. (shrink)

This article is a theoretical treatment of feminist epistemology of crime, which advocates the centrality of gender as a theoretical starting point for the investigating of digital crimes. It does so by exploring the synergy between the feminist perspectives and the Tripartite Cybercrime Framework (TCF) (which argues that three possible factors motivate cybercrimes – socioeconomic, psychosocial, and geopolitical) to critique mainstream criminology and the meaning of the term “cybercrime”. Additionally, the article examines gender gaps in online harassment, cyber‐bullying, (...) cyber‐fraud, revenge porn, and cyber‐stalking to demonstrate that who is victimised, why, and to what effect are the critical starting points for the analysis of the connections between gender and crimes. In turn, it uses the lens of intersectionality to acknowledge that, while conceptions of gender and crime interact, they intersect with other categories (e.g., sexuality) to provide additional layers of explanation. To nuance the utilitarian value of the synergy between the TCF and the feminist perspectives, the focus shifts to a recent case study (which compared socioeconomic and psychosocial cybercrimes). The article concludes that, while online and offline lives are inextricably intertwined, the victimisations in psychosocial cybercrimes may be more gendered than in socioeconomic cybercrimes. These contributions align the TCF to the feminist epistemology of crime in their attempt to move gender analysis of digital crimes “from margin to centre”. (shrink)

In the real world there are people who enter the homes and steal everything they find valuable. In the virtual world there are individuals who penetrate computer systems and "steal" all your valuable data. Just as in the real world, there are uninvited guests and people feel happy when they steal or destroy someone else's property, the computer world could not be deprived of this unfortunate phenomenon. It is truly detestable the perfidy of these attacks. For if it can be (...) observed immediately the apparent lack of box jewelry, penetration of an accounting server can be detected after a few months when all clients have given up the company services because of the stolen data came to competition and have helped it to make best deals. Cybercrime is a phenomenon of our time, often reflected in the media. Forensic investigation of computer systems has a number of features that differentiate it fundamentally from other types of investigations. The computer itself is the main source of information for the investigator.

The article is based on lyrics from 2007 to 2017 involving 18 hip-hop artists. All the songs I studied were by male singers apart from one entitled, “Maga no need pay,” which involved seven multiple artists. In all the songs, the glamorization of cybercrime and cybercriminals was one of the most significant themes. The implications are discussed.

The modern computer environment has moved past the local data center with a single entry and exit point to a global network comprising many data centers and hundreds of entry and exit points, commonly referred as Cloud Computing, used by all possible devices with numerous entry and exit point for transactions, online processing, request and responses traveling across the network, making the ever complex networks even more complex, making traversing, monitoring and detecting threats over such an environment a big challenge (...) for Network forensic and investigation for cybercrimes. It has demanded in depth analysis using network tools and techniques to determine how best information can be extracted pertinent to an investigation. Data mining technique providing great aid in finding relevant clusters for predicting unusual activities, pattern matching and fraud detection in an environment, capable to deal with huge amount of data. The concept of network forensics in cloud computing requires a new mindset where some data will not be available, some data will be suspect, and some data will be court ready and can fit into the traditional network forensics model. From a network security viewpoint, all data traversing the cloud network backplane is visible and accessible by the cloud service provider. It is not possible to think now that one physical device will only have one operating system that needs to be taken down for investigation. Without the network forensics investigator, understanding the architecture of the cloud environment systems and possible compromises will be overlooked or missed. In this paper, we focus on the role of Network Forensic in a cloud environment, its mapping few of the available tools and contribution of Data Mining in making analysis, and also to bring out the challenges in this field.

Cyber bullying affects many adolescents and teens on a daily basis; it is a form of violence that can do lasting harm to people at different ages and social status in a society. Cyber bullying is real experience that has been in existence for a quite a long time; Bullying statistics show that cyber bullying is a serious problem among teens and gaining roots among adults. By being more aware of cyber bullying, teens and adults can help to fight it. (...) Cyber bullying involves using technology, like cell phones and the Internet, to bully or harass another person. The introduction of social media and other communication systems has seen several people being bullied online by those who are already proficient on the platforms. The reasons behind cyber bullying might or might not be mala-fide but its existence isn’t in the best interest. It has been looked at mainly from the teens’ effect both in physical and psychological perception not realizing that adults are also equally affected. The impact on adults comes in different forms and has serious impact on the families and work places. The impact at work places affects productivity due to psychological trauma, legal involvement, shame/embarrassment whenever it goes public. Some people have gone to point of resigning from jobs, others have buried themselves into work for fear of victimization, others have committed suicide - At whatever level of status in society there is a great repercussion that is if situation is not put under control the victim can easily go down to a total down trend. Cyber bullying has fatal consequences and existing laws about it are woefully lacking despite some legal measures having been put in place but it gets tricky especially if the cyber bully is anonymous. There are cybercrime cells that help in preventing cyber bullying or minimize the happenings to set up a good working environment that may increase individual productivity and increase organisations profits.

This article is a theoretical treatment of the ways in which local worldviews on wealth acquisition give rise to contemporary manifestations of spirituality in cyberspace. It unpacks spiritual (occult) economies and wealth generation through a historical perspective. The article ‘devil advocates’ the ‘sainthood’ of claimed law-abiding citizens, by highlighting that the line dividing them and the Nigerian cybercriminals (Yahoo-Boys) is blurred with regards to the use of magical means for material ends. By doing so, the article also illustrates that the (...) intersectionality of the spirit world and the acquisition of wealth (crime or otherwise) is connected with local epistemologies and worldviews, and its contemporaneity has social security benefits. Therefore, the view that the contemporary manifestations of spirituality in cyberspace signify a ‘new-danger’ and an ever-increasing outrage in the Nigerian society is misplaced. I conclude that if people believe all aspects of life are reflective of the spiritual world and determined by it, the spiritual realm, by implication, is the base of society, upon which sits the superstructure comprised of all aspects of life, especially wealth. Inferentially, this conceptual position that the spirit world is the base of society is an inversion of Orthodox Marxist’s theory of economic determinism. (shrink)

This study sets out to examine the ways Nigerian cyber-fraudsters (Yahoo-Boys) are represented in hip-hop music. The empirical basis of this article is lyrics from 18 hip-hop artists, which were subjected to a directed approach to qualitative content analysis and coded based on the moral disengagement mechanisms proposed by Bandura (1999). While results revealed that the ethics of Yahoo-Boys, as expressed by musicians, embody a range of moral disengagement mechanisms, they also shed light on the motives for the Nigerian cybercriminals' (...) actions. Further analysis revealed additional findings: “glamorization/de-glamorization of cyber-fraud” and “sex-roles-and-cultures”. Having operated within the constraint of what is currently available (a small sample size), this article has drawn attention to the notion that Yahoo-Boys and some musicians may be “birds of a feather.” Secondly, it has exposed a “hunter-and-antelope-relationship” between Yahoo-Boys and their victims. Thirdly, it has also highlighted that some ethos of law-abiding citizens is central to Yahoo-Boys’ moral enterprise. Yahoo-Boys, therefore, represent reflections of society. Arguably, given that Yahoo-Boys and singers are connected, and the oratory messages of singers may attract more followers than questioners, this study illuminates the cultural dimensions of cyber-fraud that emanate from Nigeria. In particular, insights from this study suggest that cyber-fraud researchers might look beyond traditional data sources (e.g., cyber-fraud statistics) for the empirical traces of “culture in action” that render fraudulently practices acceptable career paths for some Nigerian youths.

To secure computers and information systems from attackers taking advantage of vulnerabilities in the system to commit cybercrime, several methods have been proposed for real-time detection of vulnerabilities to improve security around information systems. Of all the proposed methods, machine learning had been the most effective method in securing a system with capabilities ranging from early detection of software vulnerabilities to real-time detection of ongoing compromise in a system. As there are different types of cyberattacks, each of the existing (...) state-of-the-art machine learning models depends on different algorithms for training which also impact their suitability for detection of a particular type of cyberattack. In this research, we analyzed each of the current state-of-the art machine learning models for different types of cyberattack detection from the past 10 years with a major emphasis on the most recent works for comparative study to identify the knowledge gap where work is still needed to be done with regard to detection of each category of cyberattack.

This article is about the manifestations of similarities between two seemingly distinct groups of Nigerians: cybercriminals and politicians. Which linguistic strategies do Twitter users use to express their opinions on cybercriminals and politicians? The study undertakes a qualitative analysis of ‘engaged’ tweets of an elite law enforcement agency in West Africa. We analyzed and coded over 100,000 ‘engaged’ tweets based on a component of mechanisms of moral disengagement (i.e., advantageous comparison), a linguistic device. The results reveal how respondents defend the (...) actions of online fraudsters (“the deviant group”) by strategically comparing them to the wrongful acts of corrupt politicians (“the respectable group”). Similarly, the results show how respondents positioned this linguistic strategy to compare “the powerless group” (online fraudsters) and “the powerful group” (politicians) in society. Indeed, tweet responses suggest that the Economic and Financial Crimes Commission (EFCC) generally looks downwards for culprits (i.e., online fraudsters) while ignoring fraudulent politicians. We conclude that the process by which some actions are interpreted as a crime compared to others is a moral enterprise. (shrink)

Phishing is one of the most effective ways in which cybercriminals get sensitive details such as credentials for online banking, digital wallets, state secrets, and many more from potential victims. They do this by spamming users with malicious URLs with the sole purpose of tricking them into divulging sensitive information which is later used for various cybercrimes. In this research, we did a comprehensive review of current state-of-the-art machine learning and deep learning phishing detection techniques to expose their vulnerabilities and (...) future research direction. For better analysis and observation, we split machine learning techniques into Bayesian, non-Bayesian, and deep learning. We reviewed the most recent advances in Bayesian and non-Bayesian-based classifiers before exploiting their cor- responding weaknesses to indicate future research direction. While exploiting weaknesses in both Bayesian and non-Bayesian classifiers, we also compared each performance with a deep learning classifier. For a proper review of deep learning-based classifiers, we looked at Recurrent Neural Networks (RNN), Convolutional Neural Networks (CNN), and Long Short Term Memory Networks (LSTMs). We did an empirical analysis to evaluate the performance of each classifier along with many of the proposed state-of-the-art anti-phishing techniques to identify future research directions, we also made a series of proposals on how the performance of the under-performing algorithm can improved in addition to a two-stage prediction model.

While this article sets out to advance our knowledge about the characteristics of Nigerian cybercriminals (Yahoo-Boys), it is also the first study to explore the narratives of the Economic and Financial Crimes Commission (EFCC) officers concerning them. It appraises symbolic interactionist insights to consider the ways in which contextual factors and worldview may help to illuminate officers’ narratives of cybercriminals and the interpretations and implications of such accounts. Semi-structured interviews of forty frontline EFCC officers formed the empirical basis of this (...) study and were subjected to a directed approach of qualitative content analysis. While prior studies, for example, indicated that only a group of cybercriminals deploy spiritual and magical powers to defraud victims (i.e. modus operandi), our data analysis extended this classification into more refined levels involving multiple features. In particular, analysis bifurcates cybercriminals and their operations based on three factors: [a] educational-attainment, [b] modus-operandi, and [c] networks-collaborators. Results also suggest that these cybercriminals and their operations are embedded in “masculinity-and-material-wealth”. These contributions thus have implications for a range of generally accepted viewpoints about these cybercriminals previously taken-for-granted. Since these criminals have victims all over the world, insights from our study may help various local and international agencies [a] to understand the actions/features of these two groups of cybercriminals better and develop more effective response strategies. [b] to appreciate the vulnerabilities of their victims better and develop more adequate support schemes. We also consider the limitations of social control agents’ narratives on criminals. (shrink)

Web page phishing is a type of phishing attack that targets websites. In a web page phishing attack, the attacker creates a fake website that looks like a legitimate website, such as a bank or credit card company website. The attacker then sends a fraudulent message to the victim, which contains a link to the fake website. When the victim clicks on the link, they are taken to the fake website and tricked into entering their personal information.Web page phishing attacks (...) are a serious threat to online security. They can be very effective, as they often look very convincing. To protect yourself from web page phishing attacks, you should be suspicious of any emails or messages that ask for your personal information. Do not click on links in emails or messages from unknown senders. If you are unsure whether a website is legitimate, do not enter your personal information. Therefore, in this study, we present a novel approach to detect whether a web page is phishing or legitimate using a neural network model. (shrink)
