Webcam hacking, or camfecting, is a serious threat to your privacy and security. It involves remotely accessing your camera, often through malware installed via phishing attacks. This can allow hackers to spy on you, steal sensitive information, and even blackmail or extort you. To protect yourself, it's important to know the signs of a hacked webcam. Firstly, check your webcam indicator light. If it's on or blinking when you haven't turned it on, it could indicate a hack. Next, check your browser extensions and applications. If your webcam light turns on when you open your browser, it may be due to a malicious extension. Additionally, look for unknown applications running in the background that could be using your webcam. Check your storage files for any unexpected audio or video recordings, and review your security and webcam settings for any unauthorized changes. Finally, scan your computer for malware using reliable antivirus software. Taking these steps can help you identify and address a potential webcam hack.

What You'll Learn
Check the camera indicator light
Most webcams have an indicator light that turns on whenever the camera is in use. This light is usually hardwired to the camera, making it hard for hackers to turn on the camera without the light coming on. However, it is not impossible for hackers to override the firmware and turn on the camera without the light.
If you suspect your computer camera has been hacked, check the camera indicator light. If the light is on and you are not using the camera, this could be a sign that your camera has been hacked.
Indicator lights can sometimes be controlled by software, which hackers can access with malware. If this is the case, the indicator light may flicker on even when the camera is not in use. This could be a sign that your camera has been hacked and that someone is spying on you.
However, it's important to note that an indicator light turning on could also be due to another program or browser extension running in the background and using your webcam. To check this, reboot your computer and launch your browser. If the webcam light turns on, the problem is likely with a browser extension. You can deactivate your extensions one by one to identify the culprit and take back control.
If the indicator light is acting abnormally, such as blinking or turning on at strange times, this could also be a sign that your camera has been hacked.

Check browser extensions
If you suspect your computer camera has been hacked, one of the first things you should do is check your browser extensions. Browser extensions can access your camera, so it's important to review and remove any extensions that you don't recognise or no longer need.
Here's a step-by-step guide to checking your browser extensions:
- Reboot your computer: This will ensure that any active extensions are not running in the background when you start your investigation.
- Launch your internet browser: Pay attention to whether the webcam indicator light turns on as soon as you open the browser. If it does, it's likely that one of your browser extensions is the culprit.
- Deactivate your extensions one by one: Start by disabling all extensions and then enabling them one by one. After enabling each extension, restart your browser to narrow down which extension may be causing the problem.
- Identify and remove the problematic extension: Once you've identified the extension causing the issue, delete it immediately. It could be a poorly designed extension or a malicious attempt to access your camera.
- Consider alternative solutions: If you find an extension that you regularly use is causing the problem, look for alternative solutions. There may be similar extensions available that do not require access to your webcam.
- Keep your extensions up to date: Make sure to keep your extensions and browser up to date. Updates often include security patches and improvements that can help protect your privacy.
- Review extension permissions: Be cautious when installing new extensions. Review the permissions requested by each extension and only grant access to your camera when necessary.
- Regularly review and remove unused extensions: It's a good practice to periodically review and remove any extensions that you no longer use. This reduces the potential attack surface for hackers.
Remember, while checking your browser extensions is an important step, it's just one part of securing your computer camera. Be sure to follow additional steps, such as keeping your antivirus software up to date, covering your webcam when not in use, and regularly scanning for malware.

Check for unknown applications
If you suspect that your computer camera has been hacked, one of the first things you should do is check for unknown applications. This involves going through your list of applications and identifying any that you don't recognise or remember downloading. On a Windows device, you can do this by going to "Settings > Privacy > Camera" and scrolling through the app list to see which apps have access to your camera. From there, you can disable the apps that you don't want to use your camera.
On a Mac, you can type the command "lsof | grep “AppleCamera”" in the Terminal to see your webcam history and identify which applications have been accessing your camera. Alternatively, you can try the commands "lsof | grep “iSight”" or "lsof | grep “VDC". If you find an unknown application, you can use the process ID and the command "sudo kill -9 XXXX" to terminate the application.
It's important to note that simply disabling or removing an unknown application may not be enough to fix the issue. If you find an unknown application, it's recommended to scan your computer system for malware immediately. If malware is detected, move the file to quarantine. If this doesn't solve the problem, you may need to seek help from a tech professional.
In addition to checking for unknown applications, there are other steps you can take to enhance your computer camera security. This includes using a reliable antivirus program, being cautious of phishing attempts, and covering your webcam when it's not in use.

Check for audio and video recordings
If you suspect that your computer camera has been hacked, one way to check is to look for audio and video recordings on your device.
To do this, go to the folder where your webcam stores its files. Check your webcam's settings and whether the folder location has been changed without your knowledge. However, don't rely solely on this method, as some hackers might simply livestream everything they see through your webcam to their device.
Another way to check for audio recordings is to use a computer audio recorder. There are several options available, including:
- Chrome Audio Capture: This is a browser extension that allows you to record audio from your computer browser. Simply install the extension and choose the audio source you want to capture.
- Audacity: This is a free and professional audio capture software that can be used for any purpose of sound recording, including recording vocals, creating songs, and capturing voice calls. It offers advanced audio editing tools and supports multiple output formats.
- Movavi Screen Recorder: This is a desktop app that can capture any kind of audio on your computer, including music, microphone sound, and audio from a live stream. It also offers basic editing features such as trimming and cutting.
- Windows Voice Recorder: This is a built-in Windows tool that allows you to capture external sounds from your computer microphone. However, it doesn't capture internal audio playing on your computer.
- Screen Capture: This is an online app that records PC audio for free. It has a simple interface and can capture audio and video simultaneously or separately.
By using one of these tools, you can check for any audio recordings on your device that you don't recognise or didn't create yourself. This can help you determine if your computer camera has been hacked.
