Finding Vulnerabilities in IoT Devices : Ethical Hacking of Electronic Locks

Abstract: Internet of Things (IoT) devices are becoming more ubiquitous than ever before, and while security is not that important for every type of device, it is crucial for some. In this thesis, a widely available Bluetooth smart lock is examined through the lens of security. By using well-known attack methods, an attempt is made to exploit potential vulnerabilities in the system.The researched lock was found to have design flaws that could be considered low-impact vulnerabilities, but using the system without these flaws in mind could lead to harmful outcomes for the lock owner.Except for the design flaws, no real security problems were discovered, but the methods used in this thesis should be applicable for further IoT security research.
