A VTuber, short for Virtual YouTuber, is an online content creator who uses a digital avatar - often anime-inspired - to stream or produce videos. These avatars are typically animated in real-time using motion capture technology, which tracks the creator's movements and facial expressions. VTubers interact with their audience much like traditional streamers, but their true identities are usually concealed behind their digital personas. While VTubers are most popular on platforms like YouTube and Twitch, they can also be found on other streaming services. In cybersecurity, VTubers may face unique challenges, such as protecting their real identities, securing their motion capture data, and preventing unauthorized access to their streaming accounts or avatar assets.
