New opportunities for immersive and interactive experiences have been created by the incorporation of Virtual Reality (VR) and Augmented Reality (AR) technology into a variety of industries, including business, healthcare, education, and entertainment. But this progress also brings with it hitherto unheard-of cybersecurity risks. Cyberattacks are drawn to VR/AR environments because of the complex data streams they include, including biometric data, personal data, and real-time geographical mapping. This study investigates the cybersecurity threats related to VR/AR platforms, including identity theft, device manipulation, data breaches, and invasions of privacy. It also covers new dangers such as malware directed at immersive apps and the use of sensory weaknesses to create bodily damage in real life. These vulnerabilities are made worse by the absence of standardized security standards in VR/AR systems, underscoring the necessity of strong security frameworks. End-to-end encryption, multi-factor authentication, biometric data protection, and the creation of safe software and hardware ecosystems are highlighted as viable remedies. In addition, ethical issues pertaining to data ownership and privacy are explored, along with suggestions for legislative actions to shield consumers from online dangers. Maintaining the security of VR/AR technologies is essential to building confidence and providing consumers worldwide with secure, immersive experiences as they develop.
