How to Check If Your Webcam Is Being Used to Spy on You

With work from home becoming the norm, many of us have been relying on webcams to stay connected. These cameras let us join virtual meetings for work and online hangouts with friends. But webcam spying by bad actors can happen easily.

Someone watching through a small laptop or personal computer camera may sound farfetched. And if you don’t make a hat out of tinfoil, aliens will take over your brain, right?

Except, it is true that webcams can be used for spying.

Seeing someone with a piece of tape over their webcam isn’t that unusual. Even Facebook’s founder does it. At conferences now, you might even receive a branded sliding webcam cover as swag.

How Webcam Computer Spying Works

How can someone access your webcam in the first place? Typically, they’ve installed malware. The malicious software allows them to remotely control your computer and view its webcam.

A cybercriminal might access your webcam using spy software, a remote access trojan (RAT). The software spreads through freeware, spam emails, infected attachments, or fake website links.

The software allows the remote user to take control of your computer. They could view your online activity, read messages, or capture screens and keystrokes, and they’ll be able to turn your webcam on to spy on you – without you knowing it.

The webcam light located near the lens will indicate whether camera is currently recording. However, it’s easy to miss and many people don’t understand what the light means.

Your PC Webcam is Vulnerable to Spying

Well, there’s that piece of tape, or you might use a Post-It note to cover the camera, but that doesn’t address the bigger issue. Since we’re talking about malware here, the usual rules apply.

• Don’t trust attachments, even from people you know.
• Hover over external links to see where they will take you before clicking.
• Question the credibility of any freeware you might download onto your computer.
• Install a good antivirus system, especially one that checks emails.
• Put a good firewall in place to prevent attackers from accessing your computer.
• Install patches for your operating system, browser, and software to keep security current.

While we’re talking about webcams, keep in mind your smartphone camera and any surveillance cameras need protection too. So, if you are wondering can hackers see you through your phone camera - they most definitely can. On your phone, keep your passcode private and make sure antivirus and security patching is up to date. With a surveillance system, always change the default password – you’d be amazed how many people don’t bother to do so – as that’s just making the hackers job easy for them!

Want to be sure you’re not being spied on? Our IT experts can make sure you have a strong firewall in place to monitor network traffic and block suspicious activity. We can also ensure your antivirus and malware security is top notch.

How to Tell if Someone is Spying on Your Computer?

If you suspect that someone may be spying on your computer, it's important to take action quickly. Here are some signs and methods to detect potential spying or unauthorized activity:

1. Unusual Activity and Performance

• Sluggish Performance: If your computer is suddenly slow or unresponsive, it could indicate malicious software or spyware running in the background.
• Frequent Crashes or Freezes: Repeated crashes, freezes, or unexpected reboots may be signs of malicious activity.
• High CPU/Memory Usage: Use the Task Manager (Windows) or Activity Monitor (macOS) to check for high CPU or memory usage by unknown programs.

2. Strange Network Activity

• Unusual Network Traffic: If your internet usage seems unusually high when you aren’t using it, it could be a sign that spyware is sending data from your computer.
• Network Monitor: Use tools like Netstat (Windows) or Little Snitch (macOS) to monitor active network connections and look for suspicious or unknown activity.

3. Unknown Programs or Processes

• Unfamiliar Applications: Check for unfamiliar or unwanted programs in your list of installed applications. Spyware often hides under names that look like legitimate software.
• Task Manager/Activity Monitor: Check for running processes that you don’t recognize. Look for high-resource processes or those running from unusual locations.

4. Browser Changes or Pop-Ups

• Unexpected Browser Extensions: Spyware often installs malicious browser extensions. Regularly check your browser for unfamiliar extensions and remove them.
• Strange Pop-Ups: Frequent pop-up ads or new toolbars appearing in your browser can be signs of adware or spyware.

5. Antivirus or Security Software Disabled

• Disabled Antivirus: If your antivirus or firewall is unexpectedly turned off, it could be a sign that someone or something is trying to bypass security measures.
• Check Security Settings: Ensure your antivirus, firewall, and security software are active and running properly. If they’ve been disabled without your knowledge, it’s a red flag.

6. Unusual Webcam or Microphone Activity

• Webcam Light Turns On: If your webcam’s light turns on without your permission, it could be an indication that someone is remotely accessing it.
• Microphone Activation: Use your system’s privacy settings to check if any unauthorized apps have recently accessed your microphone.

7. Unauthorized Logins or Account Activity

• Login Alerts: If you receive alerts or notifications about logins from unknown devices or locations, it could be a sign that someone is spying on your computer remotely.
• Check Event Logs: On Windows, you can use Event Viewer to see if there’s any suspicious login activity. On macOS, you can check Console for similar log entries.

8. Suspicious Emails or Links

• Phishing Emails: Spyware is often delivered through phishing emails or suspicious attachments. Be cautious of unsolicited emails, especially if they ask you to download files or click on links.
• Account Breach Warnings: If your online accounts show signs of unauthorized access, it could indicate that your computer has been compromised.

9. Unfamiliar Files or Settings

• Unexpected Files: Look for unfamiliar files or folders that you didn’t create, especially in system folders. Spyware often hides in obscure locations.
• Altered System Settings: If your system settings, homepage, or preferences change without your intervention, it might be a sign of malware or spyware.

10. Security Software Alerts

• Antivirus Warnings: If your antivirus or anti-malware software alerts you to potential threats, take these warnings seriously and scan your system for infections.

Steps to Protect and Remove Spyware:

• Run a Full System Scan: Use a reliable antivirus or anti-malware program (e.g., Malwarebytes, Bitdefender) to scan your system for spyware or malware.
• Update Your Software: Ensure that your operating system, browsers, and applications are up-to-date to patch vulnerabilities that could be exploited.
• Check Active Connections: Use a network monitoring tool to see if there are any suspicious connections to your computer.
• Disconnect from the Internet: If you believe someone is spying on you, disconnect from the internet to prevent further unauthorized access.
• Reset Passwords: Change your passwords for important accounts, especially if you notice suspicious account activity.
• Perform a Factory Reset: If spyware is persistent and difficult to remove, consider performing a factory reset of your device. Ensure you back up essential files before doing so.

By monitoring your system for these signs and using proactive security measures, you can detect and remove spyware, protecting your computer from further intrusion.
