Abstract

Wireless home alarm systems are being widely deployed, but their security has not been well studied. Existing attacks on wireless home alarm systems exploit the vulnerabilities of networking protocols while neglecting the problems arising from the physical component of IoT devices. In this paper, we present new event-eliminating and event-spoofing attacks on commercial wireless home alarm systems by interfering with the reed switch in almost all COTS alarm sensors. In both attacks, the external adversary uses his own magnet to control the state of the reed switch in order to either eliminate legitimate alarms or spoof false alarms. We also present a new battery-depletion attack with programmable electromagnets to deplete the alarm sensor's battery quickly and stealthily in hours which is expected to last a few years. The efficacy of our attacks is confirmed by detailed experiments on a representative Ring alarm system.
