Which tool can hide a secret file within an innocuous image, video, or music file?

• A. StegoStick
• B. Snow
• C. OpenStego
• D. Spam Mimic

Answer: (A)

Hiding data inside another file is steganography—the practice of concealing a secret payload so its very existence isn’t obvious. StegoStick is a steganography tool designed to embed a secret file into innocuous media, such as an image, a video, or a music file. It works by taking your payload and encoding it within the cover file in a way that doesn’t noticeably alter its appearance or behavior, producing a stego file that looks like a normal media file but carries hidden data inside. This makes StegoStick a good fit for the scenario described, since it explicitly supports concealing a file within various types of media. Snow and OpenStego are also steganography tools, but they’re typically more limited in scope—Snow is primarily used for hiding data in images (often text), and OpenStego focuses on image-based hiding with fewer multimedia formats. Spam Mimic isn’t a steganography tool at all.
