Android Side Channel Attack

Have you heard about Spearphone, a newly demonstrated attack that takes advantage of a hardware-based motion sensor, called an accelerometer, which comes built into most Android devices and can be unrestrictedly accessed by any app installed on a device even with zero permissions?

Earlier this month, The Hacker News covered a story on research revealing how over 1300 Android apps are collecting sensitive data even when users have explicitly denied the required permissions.

The research was primarily focused on how app developers abuse multiple ways around to collect location data, phone identifiers, and MAC addresses of their users by exploiting both covert and side channels.

Now, a separate team of cybersecurity researchers has successfully demonstrated a new side-channel attack that could allow malicious apps to eavesdrop on the voice coming out of your smartphone's loudspeakers without requiring any device permission.
