    Cyber-crime Science is an emerging area of study aiming to prevent cyber-crime by combining security protection techniques from Information Security with empirical research methods used in Crime Science. Information security research has developed techniques for protecting the confidentiality, integrity, and availability of information assets but is less strong on the empirical study of the effectiveness of these techniques. Crime Science studies the effect of crime prevention techniques empirically in the real world, and proposes improvements to these techniques based on this. Combining both approaches, Cyber-crime Science transfers and further develops Information Security techniques to prevent cyber-crime, and empirically studies the effectiveness of these techniques in the real world. In this paper we review the main contributions of Crime Science as of today, illustrate its application to a typical Information Security problem, namely phishing, explore the interdisciplinary structure of Cyber-crime Science, and present an agenda for research in Cyber-crime Science in the form of a set of suggested research questions

    Artificial intelligence techniques have grown rapidly in recent years, and their applications in practice can be seen in many fields, ranging from facial recognition to image analysis. In the cybersecurity domain, AI-based techniques can provide better cyber defense tools and help adversaries improve methods of attack. However, malicious actors are aware of the new prospects too and will probably attempt to use them for nefarious purposes. This survey paper aims at providing an overview of how artificial intelligence can be used in the context of cybersecurity in both offense and defense.Web of Science123art. no. 41

    User experiences of TORPEDO: TOoltip-poweRed Phishing Email DetectiOn

    We propose a concept called TORPEDO to improve phish detection by providing just-in-time and just-in-place trustworthy tooltips. These help people to identify phish links embedded in emails. TORPEDO's tooltips contain the actual URL with the domain highlighted. Link activation is delayed for a short period, giving the person time to inspect the URL before they click on a link. Furthermore, TORPEDO provides an information diagram to explain phish detection. We evaluated TORPEDO's effectiveness, as compared to the worst case “status bar” as provided by other Web email interfaces. People using TORPEDO performed significantly better in detecting phishes and identifying legitimate emails (85.17% versus 43.31% correct answers for phish). We then carried out a field study with a number of TORPEDO users to explore actual user experiences of TORPEDO. We conclude the paper by reporting on the outcome of this field study and suggest improvements based on the feedback from the field study participants

    Each month, more attacks are launched with the aim of making web users believe that they are communicating with a trusted entity which compels them to share their personal, financial information. Phishing costs Internet users billions of dollars every year. Researchers at Carnegie Mellon University (CMU) created an anti-phishing landing page supported by Anti-Phishing Working Group (APWG) with the aim to train users on how to prevent themselves from phishing attacks. It is used by financial institutions, phish site take down vendors, government organizations, and online merchants. When a potential victim clicks on a phishing link that has been taken down, he / she is redirected to the landing page. In this paper, we present the comparative analysis on two datasets that we obtained from APWG's landing page log files; one, from September 7, 2008 - November 11, 2009, and other from January 1, 2014 - April 30, 2014. We found that the landing page has been successful in training users against phishing. Forty six percent users clicked lesser number of phishing URLs from January 2014 to April 2014 which shows that training from the landing page helped users not to fall for phishing attacks. Our analysis shows that phishers have started to modify their techniques by creating more legitimate looking URLs and buying large number of domains to increase their activity. We observed that phishers are exploiting ICANN accredited registrars to launch their attacks even after strict surveillance. We saw that phishers are trying to exploit free subdomain registration services to carry out attacks. In this paper, we also compared the phishing e-mails used by phishers to lure victims in 2008 and 2014. We found that the phishing e-mails have changed considerably over time. Phishers have adopted new techniques like sending promotional e-mails and emotionally targeting users in clicking phishing URLs

    Corporations and individuals continue to be under Phishing attack. Researchers categorizes methods corporations and individuals can employ to reduce the impact of being caught in a Phishing scheme. Corporation enable technical mechanisms such as automated filtering, URL blacklisting, and manipulation of browser warning messages to reduce phishing susceptibility costing billions of dollars annually. However, even with robust efforts to educate employees about phishing techniques through security awareness training the abundance of attacks continues to plague organizations. This study aims to identify whether a correlation exists between mindfulness and phishing susceptibility. The goal of this research is to determine if mindful individuals are less susceptible to phishing. By showing individuals with increased awareness are significantly able to identify areas that phishing attempts exploit. Based on a review of the literature a misconception exists between end-users, corporation and Internet Service Providers (ISP) regarding ownership of Phishing identification. Specifically, individuals blame ISPs and corporate information technology departments for failing to protect them from Phishing attacks. Still, the truth of the matter is that the end-user is ultimately the weakest link in the phishing identification chain. The methodology of this study polled participants through initial screening focusing on whether the individuals were mindful using the Mindful Attention Awareness Scale (MAAS) survey. Conclusions seen in this study in contrast with other studies saw no significant correlation between Mindfulness and phishing susceptibility, increase in cogitative ability or increase in Phishing identification. Thus, continued use of MAAS survey questionnaire is necessary to screen other groups for phishing awareness prior to focusing on other phishing cues

    Changing users' security behaviour towards security questions: A game based learning approach

    Fallback authentication is used to retrieve forgotten passwords. Security questions are one of the main techniques used to conduct fallback authentication. In this paper, we propose a serious game design that uses system-generated security questions with the aim of improving the usability of fallback authentication. For this purpose, we adopted the popular picture-based "4 Pics 1 word" mobile game. This game was selected because of its use of pictures and cues, which previous psychology research found to be crucial to aid memorability. This game asks users to pick the word that relates to the given pictures. We then customized this game by adding features which help maximize the following memory retrieval skills: (a) verbal cues - by providing hints with verbal descriptions, (b) spatial cues - by maintaining the same order of pictures, (c) graphical cues - by showing 4 images for each challenge, (d) interactivity/engaging nature of the game.Comment: 6, Military Communications and Information Systems Conference (MilCIS), 2017. arXiv admin note: substantial text overlap with arXiv:1707.0807

    Phishing rates are increasing yearly and continue to compromise data integrity. The need to guard business information is vital for organizations to meet their business objectives and legal obligations. The purpose of this phenomenological study was to explore security ambassadors’ perceptions of motivating their peers to adopt safe internet behaviors in a large medical campus in Minnesota. Hackman and Oldham’s job characteristic motivation theory was used to frame the study. Data were collected from semistructured interviews with 20 security ambassadors. Data coding and analysis yielded 7 themes: rewarding, value, personal interest, limited information security knowledge, increased interest, communication, and topics lacked variety. Participants stated that they perceived the ambassador program to be of value to the organization and employees, to be rewarding to the ambassador, and to generate increased interest in information security topics among their peers. Results may be used to develop intervention techniques and applications to prevent malicious phishing attempts in health care and other industries, resulting in safer patient/client environments
