Security analysis of a modern smart camera

Abstract: IoT devices have historically lacked in the security standards but at the same time it is a continuously growing market it is important that the security analyzes continue in order to evaluate the development of the security in the IoT industry. This research is a security analysis of the Deltaco SH-IPC05 WIFI Camera, it is an inexpensive device that can be accessed through a mobile application from anywhere on the internet via the cloud. It follows the Practical and Agile Threat Research for IoT (PatrIoT) methodology and is delimited to network traffic and the software of the device. Due to legal limitations the cloud is not included in the analysis and the hardware security is not included due to time constraints. The device was found to use default credentials for its Open Network Video Interface Forum (ONVIF) service, but it is easy for a user to change the default password from the mobile application if the user can guess what the default password is, and the service is not enabled by default. Three DoS attacks were identified to be effective, two of which caused the device to crash and reboot and the third one prevented the camera from responding until the attack ended. One of the attacks that consistently crashed the camera, could keep crashing the camera repeatedly thus keeping it offline. When analyzing the network traffic, it was possible to consistently detect the packets that notified users of motion or sound detection by looking for specific TCP packet sizes and ports. Although some issues were found the device appeared to be generally secure with encrypted network traffic and minimally exposed services.
