Query: Screen Gleaning: A Screen Reading TEMPEST Attack on Mobile Devices
  Exploiting an Electromagnetic Side Channel   We introduce screen gleaning, a TEMPEST attack in which the screen of a
mobile device is read without a visual line of sight, revealing sensitive
information displayed on the phone screen. The screen gleaning attack uses an
antenna and a software-defined radio (SDR) to pick up the electromagnetic
signal that the device sends to the screen to display, e.g., a message with a
security code. This special equipment makes it possible to recreate the signal
as a gray-scale image, which we refer to as an emage. Here, we show that it can
be used to read a security code. The screen gleaning attack is challenging
because it is often impossible for a human viewer to interpret the emage
directly. We show that this challenge can be addressed with machine learning,
specifically, a deep learning classifier. Screen gleaning will become
increasingly serious as SDRs and deep learning continue to rapidly advance. In
this paper, we demonstrate the security code attack and we propose a testbed
that provides a standard setup in which screen gleaning could be tested with
different attacker models. Finally, we analyze the dimensions of screen
gleaning attacker models and discuss possible countermeasures with the
potential to address them.
