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.

Checklist to See If Your Webcam Has Been Hacked 1. Is There a Light on Next to the Webcam? The light can vary in color but it should be a tiny little small dot of light peeking out from the webcam. If this light is there, your webcam is on. If you didn’t turn on the webcam and the light is there, you probably just want to restart your computer. Mar 27, 2017  REVEALED: How to tell if your PC or Mac has been HACKED FRESH technology has been developed to keep up with hackers accessing webcams. Jan 26, 2017  Mac webcams include a light that turns on when your webcam is in use. With the right command, you can check which application is actually using your webcam. Webcam spying is not some niche issue—-it’s very real.

How To Tell If Your Webcam Is Hacked Macbook Pro

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.

1. 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.

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.

2. 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.)

1. Choose System Preferences from the Apple menu.
2. Click Security or Security & Privacy.
3. Click the Firewall tab.
4. Unlock the pane by clicking the lock in the lower-left corner and enter the administrator username and password.
   

5. Click Turn On Firewall or Start to enable the firewall.
6. 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:

1. Select the Start button.
2. Select Settings, then Update & Security, then Windows Security, then Firewall and network protection.
3. Choose a network profile.
4. 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.”

3. 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.

1. Create a name and password for your router in Security Settings, then select a type of encryption (more about his in No. 2 below).
   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.
2. Choose the most secure and recent form of encryption available. That’s probably Wi-Fi Protected Access 2, also known as WPA2.
   

3. Be sure to save the updated information when prompted.

4. 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.

5. 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.
  

6. 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.

7. 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.

8. Use trusted tech support

Unethical technicians could install remote-access programs when your computer is in the shop. Make sure you trust your tech. The same goes for remote support. Giving remote control of your computer could make you vulnerable to having your webcam hijacked. Always password protect your personal data before allowing a technician to access your computer, and ensure that you’ve read the technician’s privacy policy first. After their work is completed, it’s also a good idea to change the password to any program or system that the technician had remote access to, for an added layer of security.

9. 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.

1. 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 light. Keep in mind, too, that it’s sometimes possible to turn off your webcam light in settings.

2. Run a security scan. By running a scan on your device to determine 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 learning how to secure your webcam and help prevent webcam hacking.

Sometimes it’s nice to be alone.

Get multiple layers of protection for your Cyber Safety. Don't wait!

You turn on your MacBook and feel that something is wrong: some files have disappeared, or new files were added. You wonder if someone has been watching your computer.

So, how to tell if someone is remotely accessing your MacBook? You need to check your logs, verify that no new users were created, make sure that remote login, screen sharing and remote management are disabled, and no spyware is running on your computer.

First things first. If you suspect that someone is controlling your laptop and if there is a chance that they watching you thru the webcam immediately apply a cover on laptop’s webcam. You can find my favorite webcam covers here.

What is remote access and how is it configured on MacBooks?

There are three ways to access MacOS remotely: allow remote logins from another computer, enable Screen Sharing or allow access by using Remote Desktop. Both ways are legitimate, but if you don’t remember doing any of them you need to know how to turn on and off those possibilities.

Remote login to MacOS

Computers that run MacOS as an operating system can log in to your Mac using Secure Shell (SSH). Steps to enable remote login are the following:

1. Go to System Preferences. You can get there by clicking on the apple icon on the left of the top bar. After you clicked on apple icon you will see a drop-down menu where you should click on System Preferences menu item.
2. Find Sharing folder and double click. Click on Remote Login checkbox on the left.
3. Now you have the option to allow access either for all user or only specific users.

Once Remote Login is enabled then users with access can use SSH to log in and browse your computer’s contents.

Access to Mac screen using Screen Sharing

If you need help from IT to make changes on your MacBook or maybe you are collaborating on a project and want to share your screen you can enable Screen Sharing. Steps to enable as follows:

1. Go to System Preferences.
2. Find Sharing folder and double click. Click on Screen Sharing checkbox on the left.
3. Allow access either for all user or only specific users.

Now on another Mac (from which you want to access to your Mac) start Screen Sharing app. You can start it by clicking Command and Space buttons. In a popup form type Sharing and hit Enter. Type your computer name. In my case, I had to type in “dev-pros-MacBook-Pro.local”.

A new window will pop up with the shared screen of another computer. Now you can control the screen.

Remote Desktop with Remote Management

Finally, it is possible to login to a computer with MacOS by enabling Remote Desktop. Steps to enable as follows:

1. Go to System Preferences.
2. Find Sharing folder and double click. Click on Remote Management check box on the left.
3. Allow access either for all user or only specific users.
4. There will be different Sharing options where you can fine-tune the type of access to allow: observe, change settings, delete, copy and even restart the computer.

Now you can access this Mac from Apple Remote Desktop – it’s an application you can buy from Apple Store and at the time of writing it’s cost was $79.99.

If your Mac is being monitored, it will show this image (two rectangles) in the top right-hand corner near your computer time:

When that symbol appears, you will be able to tell if you are being monitored. You can also disconnect the viewer by clicking on Disconnect option:

You can also click on “Open Sharing Preferences…” which will open Sharing folder in System Preferences.

Since the question you had was if someone remotely accessing your computer then the chances are that you don’t need any of sharing capabilities mentioned above.

In this case, check all options on Sharing folder under System Preferences to make sure that nobody is allowed to access it and turn off (uncheck) all options.

Verify if new users were created

As we’ve seen already remote login or sharing options require assigning access roles to the local users. If your system was hacked it is very likely that the hacker has added a new user to access it. To find out all users in MacOS perform the following steps:

1. Start Terminal app by either going to Applications and then Utilities folder or clicking Command and Space and typing Terminal in the popup window.
2. In the Terminal window type:

On my laptop it listed dev1, nobody, root and daemon.

If you see the accounts, you do not recognize then they probably have been created by a hacker.

In order to find when the user account was used to log in last time type the following command into the Terminal:
last

For each account, MacOS will list the times and dates of logins. If the login to any of the accounts happened at an abnormal time, it is possible that a hacker used a legitimate account to log in.

Check the logs

It may be useful to check the system logs for any possible access issues.

In order to find a system log, click on Go option in the top menu or simultaneously click Shift, Command and G. In the “Go to Folder” popup type: /var/log and hit Enter.

Now find system.log file and scan for word sharing. For instance, I found following screen sharing log entries:

These were log entries when someone logged in to my system remotely:

Check for spyware

How To Tell If Your Webcam Is Hacked Macbook

If you are still suspecting that spyware is running on your machine you can use a third party application like Little Snitch which monitors applications, preventing or permitting them to connect to attached networks through advanced rules. Setting up the rules for Little Snitch, however, could be complicated.

How To Tell If Your Mac Webcam Is Hacked

One of the common spyware applications is a keystroke logger or keylogger. Keyloggers used to be apps that record the letters you type on the keyboard, but they significantly in last years. Suffice to day that keyloggers can take screenshots every 30 seconds or even track your chat activity, including the messages sent to you.

I believe that keyloggers are much greater security threat because they are easier to install and the powerful features they offer. Check my article about keyloggers here: How to know if my Mac has a keylogger

Security Best Practices

1.Change passwords regularly
One thing you should immediately if you are suspecting that someone is logging to your system is to change your password. And the password should be complex enough so that other people wouldn’t be able to guess it. This means avoiding using things like birthdate, first or last name or relatives, house or apartment number, etc. As a rule of thumb the password must be long enough (8 – 32 characters) and include at least 3 of the following character types:

• Uppercase letter (A-Z)
• Lowercase letter (a-z)
• Digit number (0-9)
• Special characters such as ~!@#$%^&*

2.Enable Security Updates by clicking on “Automatically keep my Mac up to date” in Software Update folder in System Preferences.

3. Install Antivirus. I received a lot of emails where people described suspicious activity on their Macs. I found that in about 60-70% cases, the culprit was malwareand not someone breaking into the computer. It’s a myth that Macs don’t get viruses. If you need proof check the next article I wrote after testing 12 antivirus programs after injecting 117 malware samples on my Mac:
