Ghost in the Droid
Josh Wright at BSides Boston 2017
Ghost detection apps take many forms in the Google Play store, with an active social media community sharing screenshots, energy disturbance levels, and recorded audio and video for ethereal detection events. But what exactly do these apps do? How does an Android phone detect supernatural phenomena through EMF readings, ghost radar, visual observation, or ghost radio? Can it be explained, or do the answers lie beyond our realm of understanding? In this talk, I'll show you how I found these answers, demonstrating techniques for more efficient Android application analysis, and how you can get better at reverse engineering Android applications for security analysis.
