Abstract： Touchscreen-based electronic devices such as smart phones and smart tablets are widely used in our daily life. While the security of electronic devices have been heavily investigated recently, the resilience of touchscreens against various attacks has yet to be thoroughly investigated. In this talk, I will show that touchscreen-based electronic devices are vulnerable to intentional electromagnetic interference (IEMI) attacks in a systematic way and how to conduct this attack in a practical way. I will show how to calculate both the minimum amount of electric field and signal frequency required to induce touchscreen ghost touches. I will further analyze our IEMI attack on real touchscreens with different magnitudes, frequencies, duration, and multitouch patterns. This new attack works directly on the touchscreen circuit regardless of the touchscreen scanning mechanism or operating system. I will conclude the talk with potential solutions for touchscreen protection against IEMI, or similar, attacks.
