As the impact of cyberthreats on businesses and governments across the globe keeps increasing, it is more important than ever to understand how threat actors and groups operate in the cyber underground and in particular how they maintain their effectiveness: what makes certain actors or groups so successful? By increasing our understanding of the social patterns and psychological traits of these individuals - an area of cybersecurity often overlooked, attendees will be able to improve mitigation efforts by anticipating how future threat actors will exhibit specific characteristics and how their successes influence others to adopt similar strategies. In this session, Maurits Lucas will present the results of an analysis of more than 12 years of tracking and reporting on a variety of actors and groups in the cyber underground which allowed Intel471 to identify seven specific habits of highly effective actors and groups that Mr Lucas will present, along with examples.
