The webcam is a crucial tool for remote communication but poses privacy risks, particularly through a threat known as CamFecting, where unauthorized access can occur via malware, malicious websites, or system vulnerabilities. Preventive measures include using antivirus software, disabling the webcam when not in use, and physically covering the camera with privacy caps or tape. Signs of unauthorized access include unexpected illumination of the webcam light, unusual camera behavior, unknown files on the system, abnormal data consumption, and decreased battery life. To deactivate the webcam, users can adjust settings in major browsers and operating systems. Maintaining digital hygiene, such as regularly updating software, using security systems like firewalls and VPNs, and being cautious of phishing attempts, is essential to minimize risks.
