You have to install the tools that are used and you dont already have, in order to do it I recommend you to use the installation scripts that you can find: https://github.com/DominicBreuker/stego-toolkit ## GENERAL FEATURES - [x] Automatically detects hidden files inside a file using "Binwalk". - [x] Automatically detects metadata. - [x] Automatically extracts strings. - [x] Automatically checks the file using "File". - [x] Automatically extracts information of the file using "Identify". - [x] Automatically extracts hidden files using "Foremost". - [x] Automatically shows the entropy of the file using "Ent". - [x] Automatically shows an hexdump. ## STEGO IN IMAGES - [x] Automatically check if the is information hidden in jpg by several algorithms using "StegDetect" (Algorithms: JSteg, Outguess, JPHide, Invisible Secrets, F5, Sophisticated F5, Append at the end) - [x] Automatically check if is a real PNG file using "PNGCheck" - [x] Automatically extract hidden information of a PNG using "ZSteg" - [x] Automatically tries to extract information using "StegHide" without password - [x] Automatically runs "StegoVeritas" with parameters: -imageTransform -colorMap -trailing, in order to stract possible hidden information. - [x] Automatically tries to extract information using "JSteg" without password - [x] Automatically tries to extract information using "Outguess" without password - [x] Automatically tries to extract information using "Outguess-0.13" without password - [x] Automatically tries to extract information using "OpenStego" without password - [x] Automatically tries to extract information using "LSBSteg" without password - [x] Automatically tries to extract information using "SteganoTool" - [x] Automatically tries to bruteforce "StegHide" using the 500 most common passwords - [x] Automatically tries to bruteforce "Outguess" using the 500 most common passwords - [x] Automatically tries to bruteforce "Outguess-0.13" using the 500 most common passwords - [x] Automatically extracts strings and create new images using the LSB.
