How to stop people from accessing my MacBook webcam


The threat of unwanted access to your webcam raises sufficient malaise to arrange for precaution. In 2013, research from John Hopkins University, reported by the Washington Post, exposed how MacBook and iMac webcams could be infiltrated without activating the LED indicator light.

Apple’s security measures force any program launching from its computers’ CPU to automatically trigger the webcam LED light if it needs camera access.The research paper revealed, however, that the chip inside the iSight camera, called the micro-controller, could be reprogrammed to prevent the LED light from turning on – which is how hackers and intelligence agencies can secretly see what you’re doing.

Though the study was published in 2013 and looked at MacBook and iMac models predating 2008, the authors of the paper said newer models could continue to be exploited in similar ways.

The easiest way to prevent access to your camera is, of course, to cover it with black tape or a sticky note. But if you want a more sophisticated solution, Parallels Toolbox’s Block Camera feature may what you need.
