The Internet of Things is a platform where every day devices become smarter, every day processing becomes intelligent, and every day communication becomes informative. While the Internet of Things is still seeking its own shape, its effects have already stared in making incredible strides as a universal solution media for the connected scenario. The potential benefits of Internet of things (IoT) are almost limitless and IoT applications are changing the way we work and live by saving time and recourses and opening new opportunities for growth, innovation and knowledge creation. The Internet of Things allows private and public-sector organizations to manage assets, optimize performance, and develop new business models. Sensor is a device that detects events or changes in the environment, and transform signals from different energy domains to the electrical domain then provides a corresponding output. IoT devices are vulnerable to sensor-based threats due to the lack of proper security measurements available to control use of sensors by apps. By exploiting the sensors (e.g., accelerometer, gyroscope, microphone, light sensor, etc.) on an IoT device, attackers can extract information from the device, transfer malware to a device, or trigger a malicious activity to compromise the device. In this survey, we explore various threats targeting IoT devices and discuss how their sensors can be abused for malicious purposes. Specifically, we present a detailed survey about existing sensor-based threats to IoT devices and countermeasures that are developed specifically to secure the sensors of IoT devices.
