The paper addresses the phenomenon that consumers buy and use mobile apps extensively despite the fact that many have only little specific knowledge about them. In particular this article seeks to explore how consumers deal with the risks and possible security frauds of mobile ecosystems.

Most importantly, they have high trust in the mobile ecosystem and the actors involved in it. Furthermore, they perceive themselves of being capable to deal with the risks involved in app consumption.</p
