Capacitive Touchscreens at Risk: A Practical Side-Channel Attack on Smartphones Via Electromagnetic Emanations

Capacitive touchscreens in modern smartphones introduce severe side-channel vulnerabilities. However, existing attacks often require restrictive conditions or invasive measurements. This paper presents TESLA, a novel, contactless electromagnetic EM side-channel attack that exploits inherent EM...

Remotely Controlling Touchscreens

Researchers have demonstrated controlling touchscreens at a distance, at least in a laboratory setting: The core idea is to take advantage of the electromagnetic signals to execute basic touch events such as taps and swipes into targeted locations of the touchscreen with the goal of taking over...

Attackers Can Use Electromagnetic Signals to Control Touchscreens Remotely

Researchers have demonstrated what they call the "first active contactless attack against capacitive touchscreens." GhostTouch, as it's called, "uses electromagnetic interference EMI to inject fake touch points into a touchscreen without the need to physically touch it," a group of academics from...
