Abstract

Ransomware has emerged as one of the biggest security threats to organizations and individuals alike. As technical solutions are developed the creators of ransomware are also improving the sophistication of such attacks. A combination of technical and behavioral measures is required to deal with this problem. This study investigates computer users’ motivation to adopt security measures against ransomware, using protection motivation theory (PMT) as a theoretical foundation. We conducted empirical research, using a survey methodology, collecting data from 118 respondents. Using partial least squares structural equation modelling our analysis provides support for several factors influencing protection motivation in this context. These include perceived threat severity and perceived threat vulnerability, mediated by fear. Self-efficacy is shown as a significant coping factor. Maladaptive rewards and response costs both have a significant negative influence on protection motivation. The results provide support for the use of fear appeals and PMT to influence protection motivation in the context of ransomware threats.
