Covert channels circumvent security measures to steal sensitive data undetectable to an onlooker. Traditionally, covert channels utilize global system resources or settings to send hidden messages. This chapter introduces covert channels and focuses on a novel covert channel on Android-based Internet of Things (IoT) devices. Particularly, we were able to make a covert channel using notifications a user gets from everyday applications. The chapter will also present this covert channel by discussing the framework, evaluating the performance, and demonstrating the functionality and flexibility of the proposed model.
