Victor works as a professional Ethical Hacker for SecureEnet Inc. He has been assigned a job to test an image, in which some secret information is hidden, using Steganography. Victor performs the following techniques to accomplish the task:
1. Smoothening and decreasing contrast by averaging the pixels of the area where significant
color transitions occurs.
2. Reducing noise by adjusting color and averaging pixel value.
3. Sharpening, Rotating, Resampling, and Softening the image.
Which of the following Steganography attacks is Victor using?

I agree, Active Attacks seems to fit best here.

Definitely not Stegdetect, that's for sure.
YO

Wait, is he really doing all that just for Steganography?
SE

I think it's more like a Chosen-Stego Attack.
LE
Leila

Sounds like he's using Active Attacks.
LE

I recall that Chosen-Stego Attacks involve selecting specific images to hide data, but I’m not confident if that applies here.
RE

I feel like the techniques Victor used are more about manipulating the image rather than detecting hidden information. Maybe it's a Steg-Only Attack?
BL

This seems similar to a practice question we had on Active Attacks. I think it might be related to that, but I could be wrong.

I remember studying the different types of Steganography attacks, but I'm not entirely sure which one fits Victor's techniques.
DE

I'm not entirely sure about this, but I'm leaning towards Chosen-Stego Attack. The image processing steps seem aimed at analyzing the steganographic content rather than just detecting its presence.
LE

I'm feeling pretty confident about this one. The combination of smoothing, noise reduction, and image manipulation techniques points to a Stegdetect Attack.
DO
Dona

Okay, I think I've got this. The techniques described sound like they're trying to detect and extract hidden information, so I'm going to go with Steg-Only Attack.
CE

Hmm, I'm a bit confused by the wording here. I'll need to make sure I understand the differences between the attack types before selecting an answer.
LO

This seems like a tricky question. I'll need to carefully review the techniques mentioned and think through the different types of steganography attacks.

This seems straightforward to me. The question states that a full risk-based testing strategy has been applied, so the answer must be D. 97% of the risk items have been tested, with only 3% remaining.
VI

Okay, I've got this. Ned is looking for information and samples from the vendor, so an RFI is definitely the way to go. I'll make sure to emphasize that in my answer.

It's tricky because the loops seem a bit off. Didn't we look at something similar where we had to consider edge cases?
MA

Right, so back to A, D, and E then?
VE

Hmm, I'm a bit unsure about the "transfer balance" configuration. I'll need to double-check the details on that one to make sure I understand it correctly.

I'm going to go with 'Chosen-Stego Attack' for this one. Victor seems to be purposefully trying to extract the hidden information, rather than just passively detecting it.

Haha, Victor's like a secret agent, trying to uncover that hidden message! I bet he's having fun with all those image manipulation techniques. Just don't get too carried away, dude!

Reducing noise, sharpening, and softening the image? Sounds like Victor is really trying to enhance the image to get a better look at that hidden data. I'll guess 'Steg-Only Attack' for this one.
LE
Lenny

Yes, reducing noise and sharpening the image can help reveal hidden data.
EL
Elizabeth

I agree, he seems to be focusing on enhancing the image.
