Mathieulh's image for LV0 decryption FW 3.73 is fake in my opinion (proof in thread)
I do not know if Mathieulh did, or did not decrypt the LV0, but, from what I can tell the image shown around the net as being proof is edited.
I'm not programmer. Lines of code look like alien language to me so this is not "code proof" it's just an image analysis done by myself.
With that out of the way, let's get to it. I'm not going to get into the depths of image editing, but let's just say that whenever you paste things from one image to another, or when you cover them up using anything else than the exact same color code, noise is present around the target area. Even black (there are different shades of black).
Anyway, when image compression is applied (bmp, jpeg, png, etc) the raw file gets distorted. Most often where high contrast is present. Black and White are as high of a contrast as you'll ever going to get, so noise "naturally" appears between them following the image lines, however, if the image has been edited the noise tends to become omnipresent (it's everywhere) in the edited area.
In the attachment you will find a high contrast picture of the image that floats around the net. I think it speaks for itself.
Disclaimer : I want to point out however that this is my own opinion. This is not "fact" by any stretch of the imagination, I just applied what I know about image editing and reach a conclusion, you can reach one for yourself. If I had to chose between fake and real, I would go with fake.
Have a nice day!
