I need to make sure the content is informative but also responsible. Highlight security risks and legal issues. Maybe provide an example of using a known steganography tool like Steganography Online or Snow.exe for educational purposes. But since the user mentioned "StegSpy," maybe that's a hypothetical tool. Alternatively, they might be referring to a specific software they heard about. In any case, I should avoid providing direct download links or methods unless it's from official, trusted sources.
