Webcams should be covered when not in use because hackers could be using them to spy on people a charity has warned.
Hackers are able to gain access to victims’ computers using a piece of malicious software (malware) called a remote-access Trojan (Rat). Many Rats now include a function allowing a hacker to access the victim’s webcam without their knowledge.
The malware is spread in infected files or by tricking the victim – known as a “slave” or “bot” – into visiting a specific webpage.
The chief executive of Childnet International, Will Gardner, says it has anecdotal evidence of webcams being hacked, although it is rare.
“It’s difficult to say how commonplace it is, but it can happen,” he says. “The key advice is not clicking on links or opening attachments from people you don’t know. Pointing your webcam at a wall or covering it up can be good practice, and closing the laptop lid.
The chief executive of the government’s Get Safe Online campaign, Tony Neate, says: “The most at-risk computers are those running older software which has not been updated, and those without up-to-date anti-virus software installed, making it even more crucial that people ensure their computer has the latest version of anti-security software installed across all devices.”
Webcam safety advice:
- Webcams can be affected by viruses so be wary of emails and social network messages from strangers
- Make sure anti-virus and firewall protection is kept up to date
- Avoid putting webcams in bedrooms or other private areas
- Unplug the webcam, cover the lens or point it at a blank wall when it is not in use
- Be sure you can trust the person you are chatting to and remember webcam footage can be recorded and potentially shared online
- If you have been the victim of inappropriate sexual contact via webcam tell a trusted adult and report it to the police via the Child Exploitation and Online Protection centre (Ceop)
