[SPEC] Picture Stenography
Stteegogo

I'm not new to the whole Cloverfield thing, but yeah, I'm a guest. Razz
I'm wondering how you go about trying a password on a JPG file that was found to have jphide.. I know how to use stegbreak, and I've tried numerous dictionayr files with millions of words with no success, but I don't know how to try my own password.

Also, if you put large6.jpg into photoshop and boost the WHITE levels all the way, there's strange markings around the strap of the back of the hat, in the bottom image. I can upload in a minute and show.

Steg doesn't always mean we need to crack a password. Often it means there's actual hidden discrepencies in the photo.

A common way of finding Steg within pictures is to save them as a very low quality file. Often, the part of the image containing steg data will stand out.

The markings on the hat don't seem natural, considering this isn't a picture of a real hat, it's clearly a photoshop created hat, and those images have no purpose in being there.




This is the logo. Clearly it was pasted on, and it -used- to have a slightly different colored backround, off black.
Perhaps there's something beneath it? Or perhaps that small Slusho image itself contains something special?

This hat picture is wonky, that's for sure.

The typo made it seem importrant before, but perhaps maybe it was only a typo.

Weird that it had stenography in it though, though there is a chance of it happening by accident, which is maybe why they changed it.

Steg detection is not perfect from what I remember during ILB. Lots of pics with nothing in them came back positive for steg.

In this case, the tees and hat look like they were made on a make-your-own-apparel site like CafePress. Upload your graphics and tattoo them on pre-made shirt and hat images. Customize the stitching/piping on the hat, upload a couple crappy GIFs for the hat graphics and you'd probably get something like discrepancies in the images above.

Just my $0.02

Anyway, the hat image is gone now.

Indeed, this can be closed. Unless someone else finds something in images.

steg detection on 1-18-08.jpg
Is it worth it?

I got a positive one star on the http://www.1-18-08.com/1-18-08.jpg picture
using 1.41 sensitivity. Is it worth it to try destegging it? What do you think?

Doesn't hurt to try . . . I think that if enough people try and desteg the image and we are off track, "Big Brother" will guide us down the right path . . .
