You might have heard that hackers can access your webcam. In the age of the Internet of Things — where internet-enabled devices connect to each other on your wireless network — that’s a pretty scary notion.
It’s easier than you might think to inadvertently install Trojan horse malware on your device. You might think you’re downloading a legitimate program, or clicking on a harmless link. Once the malware infects your device, it can then install remote desktop software — meaning, hackers could get control of your device, including your webcam.
Not only might hackers be looking through the webcam on your computer or tablet, but they might also be watching through your home security system or any other device on your network with a camera.
Think about it — how far are you from a camera right now? Just about everything has a camera on it these days. So how can you help protect yourself against webcam hacking? Here are nine ways to improve your webcam security.
Check to make sure your software is up to date
Keep your software up to date. This helps patch vulnerabilities in your software that could allow hackers access to your device.
Updating your software is pretty easy on Mac and PC devices, and iOS and Android. Here’s an example of how to update — in this case, for Mac. But check out the links below to get complete instructions for updating all of your devices.
Click the Update Now button to install all available updates or click More Info to see more details about each update.
Consider selecting “Automatically keep my Mac up to date” to install future MacOS updates. This also applies to apps downloaded from the App Store.
How to update software on a PC
Click Start, navigate to Settings and click Update & Security.
Click Windows Update, then click Change active hours.
Set your preferred start and end times for active hours, then save.
How to update software on Apple iPhone, iPad or iPod touch
Open Settings, navigate to the General menu and select Software Update.
Select Download and Install.
Select Install (or select Later if you prefer to install the update later).
Detailed instructions are available on the Apple website.
How to update software on Android
Open Google Play Store, navigate to the menu and select My Apps & Games.
Locate apps labeled Update.
It’s easy to ignore those pop-up alerts that remind you it’s time to update your software. But don’t do that. Remember, your goal is to keep cybersnoops out of your devices.
And that includes minimizing the risk of anyone taking control of your webcam.
Use a firewall to lock down your network
A firewall is a network security system. It provides a wall of defense by monitoring traffic to and from your network. In short, it can help keep the bad guys out.
Your computer probably comes with a firewall, which will prevent unauthorized access to your computer. Keep in mind, most firewalls need to be turned on. If you’ve never enabled your firewall, it’s a good idea to do it now.
How to turn on your firewall on a Mac
Apple outlines the steps to take to turn on a Mac firewall. (This should work in OS X v10.6 and later.)
Choose System Preferences from the Apple menu.
Click Security or Security & Privacy.
Click the Firewall tab.
Unlock the pane by clicking the lock in the lower-left corner and enter the administrator username and password.
Click Turn On Firewall or Start to enable the firewall.
Click Advanced to customize the firewall configuration.
You can find other detailed instructions on the Apple website.
How to turn on your firewall on a PC
Do you use a PC? Microsoft has instructions to turn Windows Defender Firewall on or off. Here’s how:
Select the Start button.
Select Settings, then Update & Security, then Windows Security, then Firewall and network protection.
Choose a network profile.
Under Windows Defender Firewall, switch the setting to On or Off.
Microsoft offers other details online, plus this reminder: “Turning off Windows Defender Firewall could make your device (and network, if you have one) more vulnerable to unauthorized access.”
Secure your Wi-Fi
Hackers may target your home wireless router to gain access to your network. That means they might access things like your emails, social media or bank accounts that you’re logged in to, personal schedule, and webcam.
Here are a few basic tips to help protect against that.
Tip: Avoid naming your router something that can easily be associated with you, such as your name or address. Also, make sure you create a complex password such as one using a random string of letters, numerals, and special characters.
Choose the most secure and recent form of encryption available.
Be sure to save the updated information when prompted.
Avoid all suspicious links
Cybercriminals can gain control over your device — including your webcam — by tricking you into installing malware.
That’s why you should never click on suspicious links in emails or download files from people you don’t know. This is one of the most common ways that hackers gain access to your devices.
What’s a smart defense? Only download attachments and click on links in emails from people that you trust. Even then, if something looks suspicious, call or text them to find out if it’s legitimate. You can also search a website link to see how safe it is.
Don’t chat with strangers online
A cybercriminal might chat with you online to get your personal information or trick you into downloading malware that compromises your webcam.
Here are a few dos and don’ts to consider if you decide to chat with a stranger.
Don’t share anything that might be used to gain access to financial accounts, lead to identity theft, and enable other types of danger or fraud.
Don’t overshare. Avoid providing personal details that someone could gather in an attempt to break your passwords. Examples include date of birth, pet names, your high school or its mascot, or any of the other types of random information that could be used to crack your security questions or that you might use in passwords.
Avoid sharing a picture of yourself, your home, or anything that might lead a stranger to you.
Cover or unplug your webcam
If your camera has an indicator light, and it goes on — and you didn’t do it — it’s a likely sign your webcam has been hacked.
And if the indicator light doesn’t go on? Keep in mind that hackers can sometimes disable the light.
Indicator light aside, hackers have had real-life success hijacking webcams. For instance, hackers have used webcams to capture compromising images of unknowing victims and, in some case, have reportedly demanded ransom in exchange for not distributing the image or posting them on the web.
Some people, including Facebook CEO Mark Zuckerberg, opt for at least one low-tech solution: covering the device’s camera with a sticker or tape. You can also purchase covers online that are designed to attach to your webcam.
Get a virtual private network (VPN)
Security software does a lot of the work in blocking malware that could lead to someone remotely taking control of your webcam — but it’s smart to add another layer of security.
That’s where a virtual private network comes in.
A VPN can increase your online privacy and anonymity by creating a secured, private network from any internet connection you access. That could be in your home or on a public Wi-Fi network.
Public Wi-Fi networks can be especially vulnerable to hacking, but a VPN helps protect the data you send and receive while accessing public networks.
Use trusted tech support
Install and run security software on your devices
You might associate “connectedness” with the Internet of Things, or IoT, devices in your home. Your security software also offers a kind of connectedness — a lot of the features work together to help protect you against webcam hacking and other threats.
Free security software is available, but it often lacks a multi-layered defense against cyberthreats and it often can’t keep up with new threats as they emerge.
Subscription software helps defend against ransomware, viruses, spyware, malware, and other online threats. It also helps protect your home network with a smart firewall and helps you manage protection for all your devices.
How to check if your webcam is hacked
There are two steps you can take to help determine if your webcam is hacked.
Check your webcam light. If your light turns on while you are not using your webcam, there’s a chance that your webcam is hacked. However, another application running on your computer may have turned on the light, so ensure that all other applications are closed first.
However, just because your webcam light isn’t turned on doesn’t mean your webcam hasn’t been hacked. Sometimes, hackers can disable your also light. Keep in mind, too, that it’s sometimes possible to turn off your webcam light in settings.
Run a security scan. By running a scan on your device to determine also if your computer is infected, you can identify viruses or other security threats quickly and prevent their spread. For Windows 10 computers, go to Settings and find the Updates & Security tab, then click on Scan Now. You can also run a scan using your security software or downloading a reputable antivirus application.
At one time or another, you’ve probably had that feeling. You’re being watched. Even if it’s just you and your webcam.
That’s why it’s smart to know about webcam security. And that starts with also learning how to secure your webcam and help prevent webcam hacking.
Sometimes it’s nice to be alone.
