“…4 We used keywords such as identity theft and phishing in news search on Factiva. A similar approach has been used in previous research to identify related news on cybercrime (e.g., Bose and Leung 2014). 5 In 2013, only the top 250 of Information Week 500 were available.…”

“…The dependent variable CSAR measured the standardized short-term market reaction as a result of ITC adoption in the event window [0, 1]. Cross-sectional regression has been commonly used in previous event studies (Andoh-Baidoo and Osei-Bryson 2007; Bose and Leung 2014;Chatterjee et al 2001). It served as a robustness check alongside the event study.…”

“…The regression is shown in equation (H1). Following previous studies, quantile regression with Huber-White estimator of variance was used because this regression was known to be robust to outliers and non-normality of disturbance term, and could minimize cross-sectional and cross-correlational heteroscedasticity (Bose and Leung 2014;Koenker and Hallock 2001). The definition of variables used is shown in Table I1 and the results are shown in Table I2.…”

Previous studies on IT investment using event studies investigated different aspects of IT. For example, Dos Santos et al. (1993) studied IT innovativeness andChatterjee et al. (2002) focused on different functionality aspects of IT (e.g., infrastructure and application). Apart from general IT investment, there were also a few studies specific to IT applications (e.g., ERP, e-business, and security). Nevertheless, the steps of the event study adopted in previous studies were similar. All previous studies first analyzed abnormal return based on subsamples followed by subsampling analysis. Most studies adopted a three-day event window around IT investment announcements. Both parametric and nonparametric tests (e.g., sign test and Corrado's rank test) were used to determine the level of significance of abnormal return in the estimation period. Furthermore, most of the sample data were from the United States. Meng and Lee (2007) was the only study that compared the reaction of IT investment in the United States with that in China. A summary of previous research on IT investment using event studies is shown in Table A1.

“…Manab, Kassim, and Hussin (2010) believe that the importance of risk management practices to the companies' performances and value creation have encouraged the companies to continuously improve their risk management efforts. By studying the objectives and effects of risk management, Lien and Li (2013) and Bose and Leung (2014) propose that risk management may have protective effects on firm value, but such effects will vary with risk management measures. From the aforementioned literature, we can conclude that a correlation exists between risk management and firm value.…”

Relationship between initiative risk management and firm value: evidence from Chinese financial listed companies

This study considers 189 Chinese financial listed companies between 2009 and 2013 as research samples to establish indicators for evaluating the initiative risk management behaviour of financial enterprises. This work further examines the relationship between initiative risk management and firm value. Results show that financial enterprises could effectively increase firm value by taking initiative risk management measures, such as setting up departments or positions that specialize in risk management, using financial derivative instruments or engaging popular international accounting firms as audit institutions. Moreover, results reveal that the permeability of initiative risk management has an unstable effect on firm value, that is, a nonlinear relationship exists between the permeability of initiative risk management and firm value.

“…For instance, a total of 42,212 unique phishing websites was reported in June 2014 by the Anti-Phishing Working Group (APWG, 2014), whereas the financial loss inflicted upon worldwide organization in December 2014 was estimated to be $453 million (EMC Corporation, 2015). These alarming trends have resulted in the loss of consumers' trust in using E-commerce websites because they are feared to become fraud victims (Bose and Leung, 2014). In summary, phishing attacks have resulted in widespread leakage of sensitive information, monetary loss and crippled businesses' reputation.…”

A B S T R A C TThis paper proposes a phishing detection technique based on the difference between the target and actual identities of a webpage. The proposed phishing detection approach, called PhishWHO, can be divided into three phases. The first phase extracts identity keywords from the textual contents of the website, where a novel weighted URL tokens system based on the N-gram model is proposed. The second phase finds the target domain name by using a search engine, and the target domain name is selected based on identity-relevant features. In the final phase, a 3-tier identity matching system is proposed to determine the legitimacy of the query webpage. The overall experimental results suggest that the proposed system outperforms the conventional phishing detection methods considered.
