Explain how to use steganalysis tools.
What will be an ideal response?
ANSWER: You can use several different steganalysis tools (also called “steg tools”) to detect, decode, and record hidden data, even in files that have been renamed to protect their contents. A steganalysis tool can also detect variations of an image. If a graphics file has been renamed, a steganalysis tool can identify the file format from the file header and indicate whether the file contains an image. Although steganalysis tools can help identify hidden data, steganography is generally difficult to detect. In fact, if steganography is done correctly, in most cases you can’t detect the hidden data unless you can compare the altered file with the original file. Check to see whether the file size, image quality, or file extensions have changed. If so, you might be dealing with a steganography image.
