and activate it without the webcam owner's permission. The remotely activated webcam can be used to watch anything within the webcam's field of vision, sometimes including the webcam owner themselves. Camfecting is most often carried out by infecting the victim's computer with a virus that can provide the hacker access to their webcam. This attack is specifically targeted at the victim's webcam, and hence the name ''camfecting'', a
portmanteau
A portmanteau word, or portmanteau (, ) is a blend of wordsTrojan software through which the camfecter can control the victim's webcam. The camfecter virus installs itself silently when the victim runs the original application. Once installed, the camfecter can turn on the webcam and capture pictures/videos. The camfecter software works just like the original webcam software present in the victim computer, the only difference being that the camfecter controls the software instead of the webcam's owner.

Risk sources
A computer that does not have an up-to-date webcam software or any ''anti-virus'' (or firewall) software installed and operational may be at increased risk for camfecting. Softcams may nominally increase this risk, if not maintained or configured properly.
Preventive software
Recently{{when, date=December 2019 webcam privacy software was introduced by such companies such as Stop Being Watched or Webcamlock. The software exposes access to a webcam, and prompts the user to allow or deny access by showing what program is trying to access the webcam. Allowing the user to accept a trusted program the user recognizes, or terminate the attempt immediately.
There is now a market for the manufacture and sale sliding lens covers that allow users to physically block their computer's camera and, in some cases, microphone.
