If you’ve ever had doubts about whether your webcam is being used to spy on you. Then let us be the first to tell you that in today’s world that’s not such a crazy idea as it once was.
There have been countless reports of people’s laptop cameras being hacked. Once hackers gain access to the camera they record sensitive/personal information of the person in question and use that footage to blackmail them.
If this article, we will show you how to check if your laptop camera has been hacked and what to do about it.
How To Tell If Your Laptop Camera Has Been Hacked?
Check Your Laptop’s Webcam Light
Whenever your laptop webcam is in use, the little LED light placed next to the webcam usually illuminates in a red/yellow/blue. If your not using any application/website that is currently using your webcam and you see this light turn on.
This is the first indication that the webcam on your laptop has been hacked. If you see the light pulsating that could mean that the webcam is being used to record video.
Restart your laptop to see if this issue goes away. If it returns a little while after restarting then there could be software running on your laptop in the background that automatically takes control on the camera on startup.
However sometimes if your laptop is a few years old, that LED light might have burned out. So even if the webcam is being used you’d never know if it was hacked in the first place.
