2. OverSight


Mac malware often spies on users by recording audio and video sessions, sometimes in an undetected manner. OverSight monitors a mac’s mic and webcam, alerting the user when the internal mic is activated, or whenever a process accesses the webcam. One of the most insidious actions of malware, is abusing the audio and video capabilities of an infected host to record an unknowing user. Macs, of course, are not immune; malware such as OSX/FruitFly, OSX/Crisis, OSX/Mokes, and others, all attempt to spy on Mac users.

OverSight constantly monitors a system, alerting a user whenever the internal microphone is activated, or the built-in webcam is accessed. And yes, while the webcam’s LED will turn on whenever a session is initially started, new research has shown that malware can surreptitious piggyback into such existing sessions (FaceTime, Sykpe, Google Hangouts, etc.) and record both audio and video – without fear of detection.

    I personally just disable my mic. When it’s disabled, it won’t be detected by 3rd party software. My webcam’s led light is hardwired to the actual webcam. Which means that there is no way to turn on the webcam without opening the led light too. I think that all Laptop webcams should be made like that.

      well, both have pro and cons, if you have a laptop tracking software installed and needs to capture images via the webcam after it was stolen, then a hardwired LED defeats that purpose.

        My Laptop is used for work which means that it never leaves my side. However, I do get your point. I guess it comes down to personal preference then.

    I wonder why there are no real/physicales switches which allows to switch them off. I had an old Asus netbook (eeePC) which had an in-build slider to cover the camera. Much nicer than tape.

      Probably because of design – minimalism.
