Computer Hacking Forensic Investigator (CHFI v10) — Question 267

In which of these attacks will a steganalyst use a random message to generate a stego-object by using some steganography tool, to find the steganography algorithm used to hide the information?

Answer options

• A. Chosen-message attack
• B. Known-cover attack
• C. Known-message attack
• D. Known-stego attack

Correct answer: A

Explanation

The correct answer is A, Chosen-message attack, as it involves the use of a specific random message to generate a stego-object, which helps in identifying the underlying steganography algorithm. The other options involve either known data or do not utilize a random message in the same manner, making them unsuitable for this type of analysis.
