Explanation
Victor is performing Active Attacks against the steganographic image. Active Attacks in steganography involve deliberately manipulating or transforming the stego image to detect, disrupt, or destroy hidden data. The techniques described - smoothening, contrast reduction, pixel averaging, noise reduction, sharpening, rotating, resampling, and softening - are all image manipulation operations applied to the carrier image. These transformations attempt to remove or corrupt the embedded secret data without necessarily knowing the steganography algorithm used. The other options are different attack categories: Steg-Only Attack means the attacker only possesses the stego object; Chosen-Stego Attack means the attacker can choose which stego objects are generated; and Stegdetect is a specific automated detection tool, not an attack category involving image manipulation.
