Abstract: Information virality is an increasingly important topic in modern media environments, but it often remains overlooked in discussions about information security. This presentation will explain why information virality is a cybersecurity concern and how it can be exploited to manipulate public discourse. By utilizing theories from prominent cultural psychologists and employing natural language processing techniques, we will demonstrate methods for capturing viral discourse and identifying additional features linked to behavioral patterns that may motivate participation in discussions. This talk will focus solely on the methodology and our preliminary findings, as the research is still ongoing.
