An organization is concerned about potential attacks using steganography to hide malicious data within image files. After a recent breach, the incident response team found that an attacker had managed to sneak past their defenses by hiding a keylogger inside a legitimate image. Given that the attacker has knowledge of the organization’s steganography detection techniques, which method of steganalysis would likely be the most effective in detecting such a steganographic attack in the future?

A. Chi-square attack, where the analyst performs probability analysis to test whether the stego object and original data are identical

B. Known-message attack, where the analyst has a known hidden message in the corresponding stego-image and looks for patterns that arise from hiding the message

C. Known-stego attack, where the analyst knows both the steganography algorithm and original and stego-object

D. Chosen-message attack, where the analyst uses a known message to generate a stego-object in order to find the steganography algorithm used
