“…The authors are able to cause interruptions in a CIED, as well as dominate true signals in an ECG while using only 50 mW to transmit. A more recent paper using EMI to attack sensors, trick or heat [59], focuses on the effect of EMI on temperature sensors. In this work, Tu et al can alter the temperature of baby incubators from a distance, even through walls, with a small hand-held device.…”

“…They report that this defense can be easily and cheaply applied to almost any system and has a true positive detection rate of 100% [70]. This would be highly effective when deployed against the exploit in trick or heat [59] as it would filter malicious signals injected.…”

“…They even have been shown capable of disrupting aircraft landing systems [46]. Medical systems that are traditionally offline, such as baby incubators [59] and medical dosage regulators [43], have also been attacked. Even commonly used gyroscopes and accelerometers have been exploited [52,58], and these can and do belong to many traditional and cyber-physical systems.…”

Sensors play an integral role in numerous devices across a diverse range of domains. While cyber-physical systems and the Internet of things use them extensively, sensors can also be commonly found in many standalone electronic devices. Concerns over the susceptibility of sensors to malicious attacks have led academia to focus on the security of these sensors. To help unite these efforts, we propose a lexicon to easily differentiate between types and methods of attacks on sensors. Using these definitions, one can quickly and clearly understand the method and the target of an attack. We examine the most recent and influential attacks on sensors, especially when they are acting as edge nodes of systems, as well as defenses against said attacks. We then seek to categorize these methods according to our lexicon, demonstrating its usefulness and solidifying the meaning of proposed terms.

“…On the other hand, if the attack goal is to inject a precise waveform into the sensing system to incite a specific response from the system, the down-converted signal must closely resemble a sensor output that is known to trigger some desired behavior in the system [75] [98] [99] [100]. Thus, the injected out-of-band signal must be shaped such that when it is downconverted, it is transformed into the attacker's desired sensor output.…”

“…Temperature Sensor as Target: Tu et al [100] show that they can use EMI signals to inject spoofed readings into various temperature sensors. In this attack, they are able to manipulate temperature sensor readings by taking advantage of the amplifier without tampering with the system or triggering any alarms related to abnormal temperatures.…”

With the emergence of low-cost smart and connected IoT devices, the area of cyber-physical security is becoming increasingly important. Past research has demonstrated new threat vectors targeting the transition process between the cyber and physical domains, where the attacker exploits the sensing system as an attack surface for signal injection or extraction of private information. Recently, there have been attempts to characterize an abstracted model for signal injection, but they primarily focus on the path of signal processing. This paper aims to systematize the existing research on security and privacy problems arising from the interaction of cyber world and physical world, with the context of broad CPS applications. The primary goals of the systematization are to (1) reveal the attack patterns and extract a general attack model of existing work, (2) understand possible new attacks, and (3) motivate development of defenses against the emerging cyber-physical threats.
