How can I tell if my webcam has been hacked?
Milica Vojnic, a Data Security Expert at Wisetek explained that there are a number of tell-tale signs that can indicate someone is accessing your webcam without your knowledge:
Unfamiliar Programs or Desktop Icons: "If you notice any unfamiliar programs or icons on your computer, it could be a sign that someone has gained access to your webcam. Unusual desktop icons can be a sign that your webcam has been hacked because they may indicate that a hacker has installed remote access software on your computer."
Unusual Computer Activity: "If your computer is running slow or behaving in unexpected ways, this may be a sign that someone is remotely controlling your webcam."
Unusual network activity: "If you notice any unusual network activity, such as data being sent or received when you're not using your webcam, it could be a sign that someone has hacked into it."
The webcam LED light is on when not in use: "Normally, the webcam LED light should turn on only when you are using the webcam. If the light is on when you're not using the webcam, it could be a sign that someone else is."
Pop-up messages or notifications: "If you receive pop-up messages or notifications when you're not using your webcam, it could be a sign that someone has hacked into it."
Unusual software update: "If your webcam software or driver is unexpectedly updated, it could be a sign that someone has taken control of your webcam."
What do I do if my webcam has been hacked?
If you suspect your webcam has been hacked, you need to take immediate action, do not let the issue linger, Vojnic explained, adding some tips for if you suspect you may have been hacked.
Disconnect from the internet: "Disconnect your computer from the internet to prevent any further access by the hacker. This will stop them from being able to control your webcam or steal your personal information."
Run a full system scan: "Running a full system scan using a proper, reputable antivirus program is a necessity. This will check for any malware or malicious software that may have been installed on your system and will help to identify and remove any potential threats."
Change all of your passwords: "Change all of your passwords, especially the ones related to your email and other personal accounts in order to prevent hackers from accessing your personal information."
Uninstall any suspicious software: "Uninstall any suspicious software or programs that you may have recently downloaded or installed. This could include remote access tools or other malicious software."
Check for unauthorised access: "Check for any unauthorized access to your computer by reviewing your system logs and security settings. This will help you identify any suspicious activity and take appropriate action."
Consider disabling or covering your webcam: "If you are concerned about future hacking attempts, consider disabling or covering your webcam when not in use. This will physically prevent hackers from accessing your webcam."
How can I avoid this happening in the future?
Avoiding this can be a relatively simple process according to Vojnic, explaining some common sense steps to ensure you do not get hacked.
Use a webcam cover: "A physical webcam cover is the most effective way to prevent hackers from accessing your webcam. It is a small sliding cover that can be placed over the lens of your webcam."
Keep your operating system and software up-to-date: "By keeping your operating system and software up-to-date, you can ensure that any security patches and updates have been applied, which can help protect your computer from known vulnerabilities."
Use a firewall: "A firewall can act as a barrier between your computer and the internet, blocking incoming connections from hackers. This can help prevent hackers from being able to gain access to your computer and webcam."
Use strong passwords: "Strong and unique passwords can make it more difficult for hackers to gain access to your computer and other accounts. Avoid using easily guessable information such as your name, birthdate, or common words. Use a combination of upper and lowercase letters, numbers, and special characters to make it harder for hackers to crack."
Be cautious when downloading files or clicking on links: "Malicious files and links can be used to install malware or remote access software on your computer, which can give hackers access to your webcam. Be careful when downloading files from the internet or clicking on links in emails, and only download files or click links from trusted sources."
Use anti-virus software: "Anti-virus software can help detect and remove malware and other malicious software that may be on your computer. Keep your anti-virus software up-to-date and run regular scans to help protect your computer from hacking."
Limit the use of public or unsecured networks: "Public or unsecured networks can be vulnerable to hacking, as they may not have the same level of security as a private network. Consider using a Virtual Private Network (VPN) to encrypt your connection when using public wifi, or avoid using public wifi altogether if possible."
