Which type hides web objects behind other objects and uploads them to a web server?

• A. Web Steganography
• B. Spam/Email Steganography
• C. DVD-ROM Steganography
• D. Natural Text Steganography

Answer: (A)

Hiding data inside web-based resources and using a web server as the carrier is web steganography. This approach specifically targets web objects—like images, HTML, CSS, or other web assets—and embeds secret information within them. The data can then be uploaded to a web server as part of a covert channel, making the payload blend with ordinary web content and pass through the server unnoticed.

Other forms focus on different carriers: email steganography hides data inside emails or attachments, DVD-ROM steganography hides data within the data on a DVD, and natural text steganography conceals information within ordinary text through formatting or word choice. None of these inherently center on web objects and uploading to a web server in the same way, so the web-focused variant is the best match for the described scenario.
