“…Around 14.6% indicated that they received a text message (SMS) requesting that they urgently provide their bank account information, and that money was withdrawn from their account after providing the account information. This is consistent with the findings of [16], who reported that the majority of their respondents were victims of cyber-attacks after disclosing their banking information via text messages. Around 7.9% of respondents reported receiving a call from an unknown person claiming to be a bank customer representative, requesting their bank account information, which was subsequently provided, and money was withdrawn from their accounts.…”

Digital finance is widely regarded as one of the most effective means of financially empowering women and increasing their financial inclusion. On the other hand, cybercriminals are constantly looking for new ways to exploit vulnerabilities and developing ever more sophisticated attack methods. As a result, the cyber risk exposures and prevention of female heads of farm households in Southern Nigeria were investigated in this paper. Unsuccessful transactions by mobile applications and POINT OF SALES (POS) terminals were often encountered by female heads, and yet their money was debited, and it took a long time for their money that was debited from unsuccessful transactions to be reversed. Avoiding lonely ATMs and not going to the ATM during late hours, ignoring emails and text messages instructing them to provide online banking details, no longer using birthdates, addresses, and other words or numbers that would make it easier for attackers to figure out their passwords, and not using the same passwords for all their different accounts were the most common cybersecurity measures used by female heads. Access to digital financial products and services was influenced by factors such as marital status, household size, business experience, internet access, possession of an ICT device, and perceived security risks. These findings call for interventions by the Central Bank of Nigeria (CBN) through policies that will improve consumer education and reduce vulnerabilities, especially among women. The CBN should also develop a forum that is easily accessible to customers for filing complaints, and erring banks should be sanctioned.

“…Nigeria has also passed anticybercrime legislation, the Cybercrime Act, 2015 (Mohammed, Mohammed, andSolanke 2019). However, Nigeria appears to be severely under-resourced in terms of being able to cope with cybercrime and financial crime investigations (INTERPOL 2018h;Omodunbi et al 2016), making it fertile ground for offenders and a place where the increasingly online population may find itself at risk of being victimised from domestic or regional offenders.…”

McMurdie 2016), due to the quickly-evolving and vast nature of these crimes (Holt 2018), which typically involve more effort and cross-border expense and access difficulties than do most offline crimes in the Pursue mode. Policing has been slow to adjust to the rise of digital crimes and fraud, not least because it often means giving up functions currently performed, which meet resistance (HMICFRS 2019a(HMICFRS , 2019b."Effectiveness" in policing cybercrime needs to be clearly defined and should be seen on a spectrum. The evolution of cybercrime and cyber offender strategies is fast paced, making studying and reporting on them a difficult task. In addition to this challenge, the vast majority of research is undertaken, produced, and disseminated in English and focuses on a minority of sites where actively publishing western academics are based (Cross 2018).Yet, the scope of cyber offenders, their involvement in a range of illegal activities, and the costs of policing cyber offenders, stemming from cross-jurisdictional offences, generate serious concerns for law enforcement agencies throughout the world (Carroll and Windle 2018; Gilmour 2014; Malby et al. 2013). However, little is known about the attitudes of law enforcement towards cyber offenders in those countries in which statesponsored and state-tolerated cyber offending occurs: it is simply assumed or inferred from unsuccessful pursuit that little is being done there, at least until they victimise their local populations, setting aside often well-informed and severe reactions to those deemed to be "political opponents" or acting without authorisation from those in power. Cyber offenders operate broadly across borders, creating mutual legal assistance problems, which arise from variation in legal definitions provided by different statutes (Harkin, Whelan, and Chang 2018; McMurdie 2016) as well as institutional problems of conflicting priorities even where the offenders are not statesponsored or state-tolerated/corruptors. Except where political pressure or comity can be applied from abroad, enforcement agencies generally prioritise their domestic cases over international ones. As a result, cyber offenders encounter police services that differ in their approaches for detecting, investigating, and disrupting incidents associated with cyber offenders and their collaborators/competitors. These discrepancies, in turn, lead to uncertainties about the use of disruption strategies and their effectiveness, particularly in cross-border contexts, in addition to any uncertainties for evaluations arising from uneven but generally poor data availability.With limited resources and expertise, especially in opportunity principle countries where discretion is formally allowed, 1 law enforcement must make explicit or implicit strategic decisions in its approach, focusing on what it believes will yield the largest impacts while working within the political and economic constraints of its local CrimRxiv Evaluating Criminal Transactional Methods in Cyberspace as Understood in...

“…Cybercrimes have been defined as fraudulent activities carried out with the use of computers, the internet and other IT devices, hence the crime is digital in nature (Okeshola and Adeta, 2013). Omodunbi et al (2016) identified the forms of cybercrimes as fraudulent electronic mails, impersonation, identity theft, blackmail, forgery, cyber harassment, hacking, spamming, automated teller machine (ATM) spoofing, piracy and phishing. Broadhurst et al (2014) proposed a framework for tracking the evolution of the organisational forms that cybercrimes take to mitigate cybercrime occurrences.…”

Purpose The purpose of this study is to use a decision support model based on the Analytical Hierarchy Process (AHP) and Pareto analysis (PA) for ranking the impact of different kinds of cybercrime in organisations in the financial sector to support decisions on cybercrime mitigation. Design/methodology/approach From a structured questionnaire to the staff of 17 licensed banks in South Africa in charge of management, administration and operations, the perceived effect of cybercrime on the organisation’s goals, namely, organisation’s profitability, goodwill, customers’ satisfaction and risk management was derived. The pairwise comparison of the organisation’s goals and identified forms of cybercrime was done using the AHP. Findings The results obtained indicate that there was a consensus (100% of the answers) that the effect of cybercrime has negatively impacted the organisation’s objectives profitability and goodwill. Also, still 95.23% of the respondents agreed that the effect of cybercrime has negatively impacted the level of customers’ satisfaction, while only 7.15% saw an impact on the organisation’s risk management processes. Using these results in the AHP, analysis delivers a hierarchical order about the relevance of prevalent forms of cybercrime for the organisation´s cybercrime mitigation. The PA further shows the magnitude of the forms of cybercrime relative to each other. Practical implications Hence, this study provides a decision support framework for organisational management in the quest to explore the impact of cyber fraud. It can serve as a practical guided approach for the application of AHP analysis for the existing and emerging forms of cybercrime. Originality/value The novelty of this study lies in the fact that the combination of the AHP and PA to support solving a multi-criteria decision problem relating to the prevalence of cybercrime has not been sufficiently highlighted by the existing literature.
