Do hackers really spy on people through their phone’s cameras and webcams? The short answer: Yes. Webcams and cameras on phones can be hacked, giving bad actors full control over how they work. As a result, hackers can use a device’s camera to both spy on individuals and search for personal information. Fortunately, there are steps you can take to prevent or identify this type of activity on your phone and computer.

What can a hacker do with your device’s camera?

If a hacker gains access to your device, they can turn your camera on and off, look directly through it, take photos with it, or even listen to you using your device’s microphone. The good news (if you can call it that) is that modern devices use an indicator light or icon whenever the camera is active. If you see this light appearing at random, when you know that none of your trusted apps are using the camera, you might have a problem.

If a hacker breaks into your device, they’re probably looking for specific information, rather than just spying on you in general. In most cases, however, hackers do not target individuals. Instead, they prey on security camera data held by large corporations – in one case, giving them access to hundreds of hours of recordings 150,000 security cameras in hospitals, warehouses and prisons.

However, individuals are also targeted by hackers. Malware and other malicious files can allow hackers to access your camera, in addition to passwords or important information that you have stored on your phone or computer. Cyber ​​security best practices help you protect your computer from these files or identify them if your computer is infected.

Facial recognition and productivity trackers

Large organizations can also use cameras to track individuals. Many universities are starting to consider use facial recognition systems who follow students and professors with cameras around campus.

Privacy experts have raised similar concerns about new productivity tracking tools that have emerged in recent years. Most productivity trackers aren’t overly complex. They simply track activity on an employee’s computer, such as keystrokes and mouse movements, and report the percentage of time the employee is considered active. The software can also take screenshots which are stored online for managers to review.

However, new trackers are starting to experiment with slightly more invasive techniques, including webcams to monitor employee attention.

According to market research firm Gartner, approximately 60% of large employers use productivity tracking software to keep tabs on their employees, although most of these employers probably use the simpler tracking software. Regulatory limit what employers can and cannot track, but you may not be protected by law depending on where you live.

How to prevent your device from becoming a spy camera

If you are worried about the impact of your webcam on your privacy, there are some simple steps you can take to prevent others from using your camera maliciously.

Laptop webcam privacy covers are small pieces of plastic that fit over your camera and open or close. When closed, they prevent the camera from seeing anything, even if it is on. These covers are affordable and can be found at most electronics stores or online. Just be aware, however, that a blanket alone won’t stop hackers from eavesdropping on you or using your computer if your device is compromised.

Turning off your laptop or phone when not in use will also prevent hackers from using your camera. However, a device in hibernation or “sleep” can still be vulnerable.

Security policies can also prevent or identify camera breaches

Good general cybersecurity practices, as well as those rated by the CISA, will help you make sure a hacker is not using your camera. Knowing how to tell if your computer is infected is essential.

If your webcam’s light turns on or flashes when you’re not using it, for example, if you’re not in a Zoom meeting or if you’re not testing the camera, it could indicate that a hacker or a malware accesses it. If you notice this happening, check your device’s camera permissions to see which apps and services are using it:

  • The Windows: Start> Settings> Privacy and security> Camera.
  • Mac: System Preferences> Security & Privacy> Camera.
  • Android: Settings> Privacy> Authorization manager> Camera.
  • iOS: Settings> Privacy> Camera.

You might be surprised by what you see here. Disable permission for any app or service that you don’t want to use with your camera. Skype? Good. Random app you’ve never heard of? Wrong.

Monitoring your phone or computer for unusual storage files, strange network activity, and unfamiliar applications can also help you detect the after-effects of malware.

In most cases, you shouldn’t need to download another Windows antivirus program. While built-in tools like Windows Defender haven’t always been effective, current versions are comparable to most commercial antiviruses. Making sure your antivirus is running regular scans should protect your computer from most threats, as long as you avoid suspicious links and files while browsing the web (please don’t click on strange links).

On Mac, remember to activate the firewall. This built-in feature blocks connections from the internet and other devices to unauthorized apps and services, which can help prevent camera spyware. You will find this option in System Preferences> Security & Privacy> Firewall.

If in doubt, seek professional help

If your system appears to have a virus that your antivirus cannot catch, you can take your computer to a trusted repair store or cybersecurity expert for a closer look. Cyber ​​security is no joke and hackers are getting more and more devious; Sometimes the best approach to identify and remove spy camera malware is to take the machine to a trained professional.
