Imagine you're working on your laptop, doing homework or anything else, and suddenly the green light (or red, in my case) with your integrated webcam flashes a second and then off again. What would ignore? Or you would begin to investigate to see if it is something more serious?
If you want to know what programs are actively using your webcam, or think is working even though the indicator light is off, here's a short guide to help you.
First, you need a program that can display this information. Thanks to Windows Sysinternals, there is a practical software for this: Process Explorer.
Just you run the tool, you'll need to know the name of your webcam to identify the processes connected to it. This could be a bit complicated for less experienced users who know where to look.
If you have an integrated webcam, will appear in the menu under "Dispositivos de imagen" (my program is in Spanish) where you need to click on the detail bar, open the drop-down menu and select the device name (Physical Device Object), such as " \Device\0000009c". Copy the value and returns to Process Explorer.
Click the magnifying glass icon or press Ctrl+F and insert the device name to find the active processes that are using your webcam. If this search shows suspicious activity, you can let your antivirus check if the program is using it is malicious.
It is important to note that while Process Explorer will let you stop the selected process, not eliminate infiltrations on your machine, if there is one. Therefore, we recommend using a scanning solution reliable and multi-layered security, to locate malicious activity.
This method can also be applied to microphones, which could be targets of spyware. And if you think that will not work or you will not use the program, as simple as plugging your webcam and microphone save you from invaders.
