안드로이드 운영체제는 웹페이지에서 사용자가 입력하는 보안 정보를 가로채는 피싱 공격에 노출되어 있다. 본 논문은 피싱 공격을 가능하게 하는, 두 가지 보안 취약점을 발견하였다. 첫째, always-on-top 기법은 공격 앱이 최상위 화면 위에 투명한 UI를 배치하여 사용자의 입력을 가로챌 수 있게 한다. 둘째, 공격 앱이 웹 브라우저가 현재 방문 중인 웹페이지의 정보를 안드로이드 API를 통해 접근할 수 있다. 본 논문은 이 취약점을 이용하여 웹페이지를 공격하는 기법을 제안한다. 이 기법은 보안 관련 웹페이지 방문을 탐지하고, 이 웹페이지에 입력하는 정보를 탈취한다. 인기 있는 웹사이트를 대상으로 한 실험을 통해 제안된 기법의 정확도와 공격 위험성을 확인하였다.

Purpose - Through the analysis of the characteristics of overseas direct purchase websites and the relevant empirical analysis of the quality of service delivery, the activated theory/strategy and significance of the overseas direct purchase are sorted out. Research design, data, and methodology - In the process, to make more effective analysis, several analysis tools and analysis programmes are used, IBM SPSS Statistics 23.0 and IBM SPSS AMOS 23.0. Results - Among the characteristics of the overseas direct purchase website, the security, convenience and information provided by the overseas direct purchase have already had a positive impact on the satisfaction. The quality of the delivery service is composed of four factors: rapidity, reliability, intimacy and correctness. The research results indicate that the satisfaction level has a positive impact on the re-purchase intention. Conclusions - The significance of this study has the characteristics of overseas direct purchase sites which have confirmed that security convenience and intelligence availability have a positive impact on satisfaction and re-purchase intent. It is important to have a safe and reliable access to shopping sites on overseas direct purchase sites. In the characteristics of overseas direct purchase sites, the interaction have no positive effect on satisfaction and re-purchase intention.

The study aimed to elucidate how to design a learning environment on the premise of micro-learning (ML) and investigate its impact on website designing skills and achievement motivation among secondary school students. Adopting the experimental approach, data were collected through an achievement test, a product evaluation form, and a test to gauge motivation for achievement. The sample was divided into two experimental groups. Results revealed statistically significant differences at 0.05≥α between the mean scores of the two groups that experienced ML, irrespective of the two modes of presenting the video in the pre-test and post-test, as for the test of websites design skills, product evaluation form, and achievement motivation test. Besides, there have been statistically significant differences at 0.05≥α between the mean scores of the first experimental group that had exposure to ML using the split-video presentation style and the scores of the second experimental group that underwent ML using continuous video presentation style in the post cognitive test of website design and management skills in favor of the group that had segmented-video-presentation ML. Another salient finding is the nonexistence of significant differences at 0.05≥α between the mean scores of the first experimental group that underwent segmented-video-presentation ML and the grades of the second experimental group that received ML with continuous video presentation style in the post-application of the product scorecard of websites designing skills and the motivation test. In light of these salient findings, the study recommended using ML in teaching computer courses at different educational stages in Saudi Arabia, training computer and information technology teachers to harness ML in their teaching and using ML in designing courses at all levels of education.

Phishing website has become a crucial concern in cyber security applications. It is performed by fraudulently deceiving users with the aim of obtaining their sensitive information such as bank account information, credit card, username, and password. The threat has led to huge losses to online retailers, e-business platform, financial institutions, and to name but a few. One way to build anti-phishing detection mechanism is to construct classification algorithm based on machine learning techniques. The objective of this paper is to compare different classifier ensemble approaches, i.e. random forest, rotation forest, gradient boosted machine, and extreme gradient boosting against single classifiers, i.e. decision tree, classification and regression tree, and credal decision tree in the case of website phishing. Area under ROC curve (AUC) is employed as a performance metric, whilst statistical tests are used as baseline indicator of significance evaluation among classifiers. The paper contributes the existing literature on making a benchmark of classifier ensembles for web phishing detection.

급변하는 IT환경만큼 다양한 형태의 외부 침입에 의한 보안이슈가 발생하고 있다. 웹 어플리케이션에 대한 취약점을 이용한 공격은 갈수록 늘어나고 있고, 각 기업은 취약점 발생의 원인을 찾아서 조치하여 외부 침입을 막고 자사의 시스템 및 주요 정보를 보호하기 위해 노력하고 있다. 특별히 감독규정에 의하여 각 금융기관 및 전자금융업자는 6개월에 한번 씩 공개용 홈페이지에 대한 취약점 분석평가를 실시하고 그 결과를 금융위원회에 보고하도록 되어있다. 본 연구에서는 감독규정에서 정의하는 웹 취약점 항목을 기준으로 실제 금융기관의 점검 사례를 바탕으로 발생빈도가 높은 항목을 분석하고 이에 대한 효율적인 대처방안과 발생을 미리 예방할 수 있는 방안을 제시하고자 한다.

Purpose - Transparency, seller reputation, and website security are considered to be important factors that influence online customer purchasing decisions in China. This paper empirically examines the relative influence of Taobao.com on customers' online purchasing decisions. Research design, data, and methodology - We perform structural equation analysis, with a sample of 306 observations. The data comes from consumers' real transaction experiences from a specific website. This gives the results of our study more generalizability than studies using subjects who are not asked to engage in real transactions. Results - The results of this study reveal that perceived security and perceived reputation are critical factors affecting consumer trust and perceived transparency is most closely associated with purchase intention. Conclusions - The findings suggest that perceived transparency plays a significant role in increasing online consumer's purchase intention. The knowledge of the relative impacts of these factors and their roles in the customer transaction experience will be useful in developing customized sales strategies. The results of this study reveal that perceived transparency exerts a stronger effect than perceived reputation on consumer purchase intentions.
