Aperi'Solve

I . What is Aperi'Solve?

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.

II . Why Aperi'Solve

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.

III . Features

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

IV . Application

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.

V . Run with Docker-Compose
