Hey ChatGPT, Is This Message Phishing?
No full textThis paper investigates the effectiveness of AI-based tools, with a focus on utilizing ChatGPT as a test platform, in email phishing detection, addressing the pressing need to combat this pervasive threat in the digital landscape. With phishing attacks causing substantial financial losses amounting to billions of dollars annually, innovative approaches are essential to mitigate their impact. We propose leveraging ChatGPT for email phishing detection, capitalizing on its machine learning and natural language processing capabilities to classify emails based on nuanced patterns and variations in phishing techniques. Unlike traditional rule-based approaches, AI-based tools offer a promising avenue for enhanced detection accuracy. Through rig-orous testing focusing on binary mail classification, incorporating metrics such as accuracy, specificity, sensitivity, precision, and the F1 Score, ChatGPT demonstrates commendable performance, achieving an overall accuracy of 75.75% and an impressive sensitivity of 98.4 %. These findings underscore the potential of AI-based tools as valuable assets in mitigating phishing threats. Comparison with FortiSandbox, a widely-used solution, reveals promising potential for AI-based tools, albeit with recognition of the need for further development and refinement. Our evaluation, encompassing various aspects of. eml file analysis, highlights both the strengths and limitations of AI-based tools in identifying phishing emails. While this research lays a strong foundation for leveraging AI -based tools in email phishing detection, there exist opportunities for improvement. Addressing identified limitations and exploring future research directions will be crucial in advancing the efficacy of AI-based tools and enhancing email security measures against cyber threats
Attacks and vulnerabilities of Wi-Fi Enterprise networks: User security awareness assessment through credential stealing attack experiments
No full textEnterprise Wi-Fi networks are essential for businesses and public administrations as they provide a perfectly scalable and secure system. In the university environment, they are often deployed to offer services to students. One of the most famous university Wi-Fi Enterprise networks is Eduroam, which stands for education roaming; it is a worldwide Wi-Fi access and roaming service widely adopted by the international research and education community. It is based on 802.1x mechanisms that use TLS tunnels for achieving mutual authentication goals, and, as such, it requires careful configuration of mobile devices and responsible users’ behaviors to avoid trivial attacks carried out with rogue Access Points (APs). Differently than employees in a corporate network whose devices are properly configured by ICT teams, the user base of Eduroam consists of (likely) millions of students and professors around the world, with a myriad of different and uncontrolled devices. To assess the security of 802.1x in general, and more specifically that of Eduroam, we ran attacks against two communities of students of increasing size in order to test how users (and their devices) react when rogue 802.1x APs appear in the list of available networks. We then focused our attention on devices, and investigated their detailed dependence on different WPA-Enterprise configurations and certificate settings. The aftermath is that, even with a completely passive attack (users are keeping devices in their pockets), it is possible to steal credentials from more than one-third of the students. While most of the 802.1x vulnerabilities employed in this work should be considered somewhat known (being disclosed in former technical papers), our work appears to raise a threefold concern: (i) most pragmatic 802.1x configurations appear to be grossly insecure; (ii) no Apple's iPhone felt in our attack unless explicitly forced by the user, owing to its reduced possibility for a user to misconfigure the terminal; and (iii) the awareness of Wi-Fi authentication threats even in relatively skilled end users is close to zero
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
