The Mac version of the Shazam music discovery application keeps the device’s microphone active even after the user has switched off the app. While it doesn’t appear that Shazam is trying to spy on users, this behavior does have some security implications.
Patrick Wardle, director of research at Synack, recently warned that malware could silently spy on Mac OS X users through the device’s webcam and microphone by piggybacking on legitimate applications that use these functions, such as FaceTime and Skype.
