Research SummaryWe examined darknet user discussions on the Dread forum to identify key themes and emerging topics in fraud planning, focusing additionally on elderly victimization. Using the conceptual framework of criminogenic learning to study the process of fraud planning in darknet communities of practice, we analyzed the content of original user posts (n = 818) and comments (n = 1365) collected from the Dread forum. We identified nine unique fraud categories, of which payments‐related fraud was the most‐discussed fraud category and accounted for 25% of original user posts. We further found our sampled forum content to be dominated by the theme of learning or knowledge sharing in eight of the nine fraud categories, which appeared in more than 44% of original user posts. Our content analysis revealed specific insights into why and how darknet forum users may target people, including the elderly subpopulation, for different types of fraud. Overall, our research demonstrates the diversity of opinion and knowledge sharing among darknet forum users in relation to planning and committing fraud against the elderly, views on who is a suitable target and why, and what veteran and aspiring fraudsters consider to be important information for success in fraud.Policy ImplicationsUtilized independently or as part of a multistage strategy of darknet data analysis, our research method can be used to monitor criminally active darknet forums for current and emerging themes in fraud against general populations and vulnerable subpopulations, such as the elderly, and to develop strategies to identify, disrupt, or destroy hubs of criminal planning and knowledge sharing. Our study additionally informs policy makers of certain elder‐specific vulnerabilities that might be addressed by more up‐to‐date elder cybercrime awareness campaigns and initiatives. Our findings also highlight the presence of insider threats that may inform discussions on how health and financial institutions can better regulate these cybersecurity risks.
