Abstract

It is undeniable that sensors are the backbone for any IoT, smart devices or Industrial Control Systems and have been playing an important role in the technology world. They play a major role in taking inputs from the surrounding and giving output to the respective systems. But what if these sensor based systems operate in an unintended manner? What if their inputs inadvertently lead to compromising the system? Also, how often do organizations talk about security in Sensors? In this talk we will discuss various attacks which can be used to hack sensor based systems using Physics. This talk will also discuss some mitigations for such attacks.

Physics has been an important part of our daily life electronics, straight from the smartphone we own to the cars and everything in between have sensors installed in their respective hardware. Since there are sensors installed in the hardware, any attacker can modify the electrical signals received in the sensors and cause the device or target system to behave in a different way and compromise the system.

Key topics covered include optic spy attacks, transduction attacks, electromagnetic interference (EMI) attacks, lamphone attacks, and UV-light based attacks, along with mitigations for each.
