Apple's MacOS is known to be one of the more secure operating systems out there. However, due to its increasing popularity and expanding user base, hackers and cybercriminals are starting to victimize iMacs and MacBooks more and more.
One particular worrisome attack is webcam hijacking and spying. These kinds of exploits allow hackers to secretly record video and audio from a compromised computer.
We've warned you about recent Mac malware like Eleanor and the cross-platform threat Mokes that purport to take over webcams, but unauthorized activity from these infections is easy to spot. The Mac's built-in iSight video camera has firmware-level protection that turns on the embedded camera's LED light whenever it's in use, even by malware.
This makes it harder for hackers to access the Mac's camera undetected since the light indicator always alerts the user whenever the camera is being used. If your webcam light turns on without your consent, then that's a sure sign that someone is accessing it remotely.
But what if the malware activates when you are using your Mac's camera on purpose?
