I am currently trying to figure out a steganography challenge. I was given 3 images, a secret.txt file and a "binary" file. There are no instructions as this was part of another challenge. I am looking for someone to point me in the right direction. I just cant seem to make anything out of it lol. Here is a link to the files.
Not looking for anyone to solve this for me, just offer some guidance on tools to use and what direction to go. Thank you for your help.
For JPG images it is possible to use a tool called Stegdetect to identify images which are suspicious to bare the steganographic content and identify a tool used to hide the message. It can even try to decode or bruteforce some of the algorithms. Original site of the tool disappeared from internet, but you can still download the tool from some trustworthy archives like Debian - https://archive.debian.net/etch/utils/stegdetect Here is guide how to install on Kali linux - http://rfc.red/installing-stegdetect-in-kali-linux/ http://freecode.com/projects/stegdetect/
