Which type hides one OS in another?

• A. Video Steganography
• B. DVD-ROM Steganography
• C. Web Steganography
• D. Hidden OS Steganography

Answer: (D)

Steganography is about hiding data inside other data so it remains unseen. When that hidden data is an entire operating system, the approach is described as Hidden OS Steganography. This type focuses on concealing a second OS within a host environment so that normal tools and users don’t notice its presence, and it can be booted or accessed in a controlled way. The idea is not just to hide small files or messages inside media or web content, but to embed a complete operating system inside another system’s space—often by using hidden partitions, specialized bootloaders, or other stealthy storage methods that keep the hidden OS out of sight. Video steganography hides information inside video files, DVD-ROM steganography hides data in DVD media or its structure, and web steganography hides data within web content or traffic. None of these describe concealing an entire operating system within another, which is why Hidden OS Steganography is the best fit.
