<p>Many countries are becoming aging societies and Korea is not an exception. This study explores the vulnerability of the elderly to online phishing scams, focusing on South Korea. We examine how the rapid adoption of digital technology has left the elderly susceptible to cybercrime, particularly online fraud. Semi-structured interviews with elderly persons were conducted and the interview data were analyzed using thematic analysis. The themes that emerged from the data include the widespread use of smartphones for daily activities, a lack of knowledge and readiness regarding online fraud, dependence on intimate relationships for support and advice, and insufficient provision of public and private support mechanisms. Reflection on some key theoretical frameworks related to aging, vulnerability, and victimhood reveals that the elderly’s characteristics, such as trustfulness and loneliness, as well as the social conditions in which they are embedded, increase their risk of victimization. The findings highlight that government interventions, such as the establishment of centers to support the online activities of the elderly, are needed to protect the elderly from online fraud and to improve their digital literacy and security awareness.</p>
