Why You Want to Cover Up Your Webcam

Some of the most security-conscious people in tech keep a piece of tape over their laptop camera. There is a good reason for that.

Webcam spying sounds like science fiction, but it is a real and well-documented threat. Remote access trojans, often called RATs, can give an attacker full control of a computer, including the camera and microphone. They usually arrive the same way other malware does: through a malicious attachment, a pirated app or a fake update.

The real risk

How cameras get hijacked

Once a RAT is installed, an attacker can quietly take pictures or record video. Many laptops show an indicator light when the camera is on, and that light is a helpful signal, but it should not be your only line of defense. Users often miss it, and external or older cameras may not have a reliable indicator at all.

Criminals use captured images for blackmail, and some sextortion scams simply claim to have footage in the hope that frightened people will pay. Either way, the camera becomes leverage.

A physical cover is a control that malware cannot switch off.

Cover it, but don’t stop there

A sliding webcam cover costs a few dollars and takes seconds to install. Many newer laptops include a built-in privacy shutter. Use it whenever you are not on a call. Just remember that the microphone is not blocked by a camera cover, and a compromised computer has far bigger problems than the camera.

• Keep software updated: Most malware relies on known, already-fixed vulnerabilities.
• Review app permissions: In Windows and macOS privacy settings, check which apps can use the camera and microphone and remove any you do not recognize.
• Avoid pirated software and random downloads: They are one of the most common ways RATs are delivered.
• Use reputable endpoint protection: Modern tools can flag remote access software behaving suspiciously.
• Watch for signs: An indicator light that turns on unexpectedly, strange network activity or new programs you did not install.

About sextortion emails: If you receive a message claiming someone recorded you and demanding cryptocurrency, it is almost always a bluff sent to thousands of people, sometimes quoting an old leaked password to seem believable. Do not pay or reply. Change that old password if you still use it anywhere, and report the email.

Simple, cheap, effective

Security does not always require expensive tools. A small cover, sensible app permissions and a well-maintained computer remove one of the creepiest risks on the list, and give you real peace of mind during every video call.
