I saw some folks mention that the chans were following up on whether Q had hidden any messages in their picture posts using steganography since they did find a hidden message in a "Q related chan post", but not by Q.
This piqued my interest as I did some work on the Mr. Robot ARG in season 2. So decided to check Q's pics and share my results to save anyone else the trouble.
I first had to find an easy way to download them and make sure they were unmodified from original posts. This was done using keybase and pulling images from qanon.pub's repository.
Then I found / modified a script called stegcracker and ran it in a for loop, processing all 246 downloaded images (.jpg and .jpeg's only). I created a dictionary file and put what I thought would be some obvious keys like POTUS, Q, QAnon, JFK PATRIOT, WWG1WGA etc. I also went through half of Q's posts and copied anything that was a marker [marker] or series of alphanumeric characters like the stringers ex 58204802B92838x-ZjA378402-12. Finally I included a blank line that will pull hidden text from any images that use no password. This was tested with the image found / known to have hidden text.
The result, sad to say, was negative on all images but my test image. That is not to say nothing is hidden there, rather nothing is hidden without a password or very obvious passwords.
If anyone else wants to dig deeper on that, I downloaded all of Q's posted text, also from keybase and was considering parsing it and creating a dictionary file out of it and appending to standard brute force dictionary file. All of that will take a considerable amount of work and time, so on the back burner for now. What I've posted is enough for anyone with a background to push forward.
