Aperi'Solve is a platform which performs layer analysis on image.
The platform also uses "zsteg", "steghide", "outguess", "exiftool", "binwalk", "foremost" and "strings" for deeper steganography analysis.

Even if Aperi'Solve is available at the URL https://www.aperisolve.com, you can install a cli alias with the following command:

sudo sh -c"$(curl -fs https://www.aperisolve.com/install.sh)"

Aperi'Solve has been created in order to have an "easy to use" platform which performs common steganalysis tests such as LSB or steghide. The platform is also a quick alternative for people who didn't manage to install zsteg (ruby gem) properly.

Aperi'Solve is based on Python3 with Flask and PIL module, the platform currently supports the following images format: .png, .jpg, .gif, .bmp, .jpeg, .jfif, .jpe, .tiff.

The platform allow you to:

• Visualise each bit layer of each channel for a given image (ie. LSB of Red channel).
• Browse and Download each bit layer image.
• Visualise zsteg informations such as text encoded on LSB
• Download zsteg files such as mp3 encoded on LSB
• Download steghide files using a defined password
• Download outguess files using a defined password
• Visualise exiftool informations such as geolocation or author
• Visualise binwalk informations
• Download binwalk files such as zip in png headers
• Download foremost files such as zip in png headers
• Visualise strings output

The Aperi'Solve platform is a Flask web service (/web) (python 3.7) with backend daemons (/backend) which perform analysis.

Both of the two part has its own docker container.

You can pull all the images from the GitHub Container Registry. A simple docker compose file is included in the repos. Just use:

docker compose -f docker-compose.yml up

Then check your browser at http://localhost:5000/.
