Individuals and organizations are relying on social media in sharing information and knowledge. On the other hand, criminals find social media applications as a rich place to attack using techniques like phishing, fraud, and blackmail. While the rate of blackmail crime is growing, there is a lack of literature. The dangerous consequences of online blackmail alert organizations to have certain regulations related to information security. This study aims to examine the impact of information security regulation factors like information security awareness, policies, and culture toward avoiding online blackmail threats. The study proposes a model that has constructs from technology threat avoidance theory (TTAT), the theory of planned behavior (TPB), and organizational control (OC). A quantitative approach based on an online survey was conducted to collect data from 547 employees and students from different industrial backgrounds. SPSS and SmartPLS software were used to analyze the collected data. The results show that information security culture and information security awareness has an impact on user's motivation to avoid online blackmail threats through attitude. Furthermore, perceiving a mandated policy significantly impacts avoidance behavior. In addition, apathy and anticipated regret have a significant role in avoidance motivation. These results give evidence on the importance of the social factors in impacting the avoidance motivation using TTAT model. It contributes theoretically to having a basic and conceptual framework for future studies related to TTAT. Practically, the study encourages organizations to focus more on specifying policies and building an information security culture to ensure compliance and motivation by users to avoid these threats. Besides that, it shows the importance of having a mandated formal policy in impacting the user to behave correctly in avoiding online blackmail threats.
