“Security researcher and former NSA staffer Patrick Wardle is this afternoon demonstrating a way for Mac malware to tap into live feeds from the built-in webcam and microphone,” ben Lovejoy reports for 9to5Mac. “His presentation is being delivered at the Virus Bulletin conference in Denver later today.”

“Although any unauthorized access to the webcam will light the green LED – a firmware-level protection that is exceedingly difficult to bypass – Wardle’s presentation shows how a malicious app can tap into the outgoing feed of an existing webcam session, like a FaceTime or Skype call, where the light would already be on,” Lovejoy reports.

“Wardle has created an app that monitors webcam and microphone activity, and will alert you when a new process accesses either,” Lovejoy reports. “A pop-up will alert you, advise the name of the process and ask whether you want to allow or block access.”

MacDailyNews Take: We’ve been taping our Mac cameras for several years. Call us paranoid, but first see the related articles below. That’s why we use camJAMR iSight camera covers on our iMacs and MacBook Airs. They’re black, so they work perfectly with our iMacs and they’re removable/reusable. We’ve stuck and unstuck them hundreds of times. We just leave them on and peel them aside when we want to use the iSight camera.
