How to search for evidence of Camfecting (webcam hacking) on MB? I'm worried about camfecting (webcam hacking). The built-in camera light on my macbook (running OSX) is not on, but it isn't hard wired so that doesn't say a lot.

Can I watch outbound traffic in activity monitor to detect data egress (live streaming seems most likely when camfecting is in progress)?
Objective See has an application that continuously monitors webcam and microphone activity called OverSight. It throws up a notification if either become active and has worked well for me. 

Note: the developers rightly warn that this software may not catch all malicious use of the webcam or microphone.
