Computer Cameras: Always On?

Computer cameras can be a window into your life, and it is possible for hackers to take over your camera without your knowledge. While the indicator light is a warning sign, it can be disabled by an attacker. There have been instances of webcam spying by government agencies, schools, and individuals. To protect your privacy, it is recommended to cover your webcam when not in use and to update and patch your devices, drivers, and applications regularly.

How to know if your camera is hacked

While it may sound like a plot from a Hollywood film, it is possible for someone to hack your camera and spy on you. This is known as "camfecting" and can be achieved by slipping remote-control malware into your device. This gives hackers access to your camera, as well as your personal files, messages, and browsing history.

• Check your camera indicator light: If the light is on or blinking, even though you haven't turned on your camera, it could be a sign of spying. However, it could also be another program or browser extension running in the background, so further investigation is needed.
• Check browser extensions: Reboot your computer and launch your browser. If the camera light turns on, the issue is likely with one of the browser extensions. Deactivate them one by one to identify the culprit.
• Check applications: Launch applications one by one and see if the camera indicator light turns on. If it does, you've found the problematic app. Unfamiliar or unnecessary apps should be uninstalled immediately.
• See if your webcam process is running: Go to the Task Manager and look for all currently running programs. Check for webcam utility, but don't panic if you find it, as it may be a default setting. Restart your computer and check if the webcam utility has started automatically.
• Try running the webcam: Close all programs and apps and activate your webcam. If you get an error message stating that your camera is already in use, it might be hacked.
• Look for audio and video recordings: Check the folder where your webcam stores its files. Go through your recordings and see if there are any you don't remember making. Also, double-check your webcam's settings and folder location, as hackers may change this to hide their activity.
• Run a malware scan: If you find unfamiliar software using your camera, scan your system for malware immediately. If this doesn't solve the problem, consult a tech professional.

Additionally, here are some extra tips for computer cameras specifically:

• Check the data flow of your security camera: Track the data flow on your network and pay attention to sudden spikes in network traffic, which can indicate invalid logins or unusual activity.
• Check for strange noises: If you hear strange voices or noises coming from your security camera, it's a sign that someone is spying on you.
• Observe abnormal movements: If your security camera is following your movements or rotating abnormally, it may have been hacked.
• Check security settings: Check if the security settings or password has been changed. Hackers may leave their mark by changing the camera name to something like "Upgrade Firmware" to show off their talents.

How to avoid computer camera spying

Computer cameras can be hacked, giving malicious actors control over how they function. This means that hackers can use your device's camera to spy on you and search for personal information. Luckily, there are several steps you can take to prevent or identify this type of activity on your device.

Use a firewall

A firewall protects your system by monitoring network traffic and blocking suspicious connections. Check your security settings and make sure your computer's built-in firewall is up and running.

Use a reliable antivirus

Choose an antivirus with advanced protection against malware, spyware, and viruses. An antivirus program will detect and neutralise malicious threats before they can do any harm.

Avoid phishing traps

Hackers may disguise themselves as support agents and contact you about an issue with your system. They may then ask you to download remote-access software, which will allow them to access your camera and manage its permissions. Treat emails from unknown senders with caution and don't click on suspicious links or download attachments.

Stay secure on public Wi-Fi

Public Wi-Fi networks are extremely vulnerable to hacking. Always use a VPN to secure your connection and protect yourself from unwanted snoopers.

Cover your webcam

This is the easiest and most reliable way to prevent someone from watching you through your computer camera. You can use tape or buy a webcam cover that attaches to your device and slides open or closed.

Question what hackers have on you

If you receive threatening messages claiming that someone has hacked your webcam, don't take it at face value. These may be social engineering attacks, where scammers try to play with your emotions without having any actual footage of you.

Can someone hack your webcam without the light coming on?

The short answer is yes. While the indicator light on your webcam can alert you to a potential hack, it is not always reliable. There are some advanced attacks that can take over your laptop's camera without the light blinking.

In theory, the indicator light should be hardwired to turn on when the camera starts recording. However, whether or not the light switches on depends on the device's firmware, which can be overridden. Researchers proved this back in 2013 when they managed to hack a MacBook camera without the LED light ever coming on.

If you suspect that your webcam has been hacked, there are several steps you can take to check and enhance your computer camera security:

• Check if the camera indicator light is on. If the light is on or blinking even though you haven't turned on the webcam, it might be a sign that your device is spying on you. However, it could also be another program or browser extension running in the background, so further investigation is needed.
• Reboot your computer and launch your browser. If the webcam light turns on, the problem is likely with a browser extension. Deactivate your extensions one by one to identify the culprit.
• Check known and unknown applications. Launch applications one by one and see if the webcam indicator light turns on. If it does, you've found the issue. If not, continue testing applications until you find the one using the webcam.
• See if your webcam process is running. Go to the Task Manager and look for all currently running programs under the Processes tab. Don't panic if you find the webcam utility here, as it may simply be a default setting to launch upon reboot. To test this, restart your computer and check if the webcam utility has started automatically.
• Try running the webcam. Close all programs and apps and activate your webcam. If you get an error message stating that your camera is already in use, it might be hacked or there could be an app running in the background.
• Look for audio and video recordings. Go to the folder where your webcam stores files and check for any recordings you don't recognise. Also, double-check your webcam's settings and folder location to ensure they haven't been changed without your knowledge. However, don't rely solely on this method, as hackers may be livestreaming instead of recording.
• Run a malware scan. If you find unfamiliar software, scan your system for malware and move any suspicious files to quarantine. If the problem persists, consult a tech professional.

To avoid webcam hacking, it's important to be proactive with your cybersecurity. Here are some tips to protect your webcam from hackers:

• Use a firewall to monitor network traffic and block suspicious connections.
• Install a reliable antivirus program with advanced protection against malware, spyware, and viruses.
• Be cautious of phishing attempts, such as emails from unknown senders or people disguising themselves as support agents.
• Stay secure on public Wi-Fi by using a VPN to protect your connection.
• Cover your webcam with tape or a sliding cover when not in use.
• Be sceptical of threatening messages claiming to have webcam footage of you. These could be social engineering attacks aimed at playing with your emotions.

Why cover your webcam?

While it may seem like an exaggeration from movies and TV shows, the idea that someone could hack your laptop camera and spy on you is not too far-fetched.
