Imago Forensics - Imago Is A Python Tool That Extract Digital Evidences From Images


Imago is a python tool that extract digital evidences from images recursively. This tool is useful throughout a digital forensic investigation. If you need to extract digital evidences and you have a lot of images, through this tool you will be able to compare them easily. Imago allows to extract the evidences into a CSV file or in a sqlite database. If in a JPEG exif are present GPS coordinates, Imago can extract the longitude and latitude and it can convert them to degrees and to retrieve relevant information like city, nation, zip code... Imago offers also the possibility to calculate Error Level Analysis, and to detect nudity these functionalities are in BETA.

Setup

Setup via pip
  1. Install imago:
$ pip install imago
  1. Once installed, one new binary should be available: :
$ imago
And then it should output the imago's banner

Requirements:
python 2.7
 exifread 2.1.2
 python-magic 0.4.15
 argparse 1.4.0
 pillow 5.2.0
 nudepy 0.4
 imagehash 4.0
 geopy 1.16.0

Usage
usage: imago.py [-h] -i INPUT [-x] [-g] [-e] [-n] [-d {md5,sha256,sha512,all}]
                 [-p {ahash,phash,dhash,whash,all}] [-o OUTPUT] [-s]
                 [-t {jpeg,tiff}]
 
 optional arguments:
   -h, --help            show this help message and exit
   -i INPUT, --input INPUT
                         Input directory path
   -x, --exif            Extract exif metadata
   -g, --gps             Extract, parse and convert to coordinates, GPS exif
                         metadata from images (if any)It works only with JPEG.
   -e, --ela             Extract, Error Level Analysis image,It works only with
                         JPEG. *BETA*
   -n, --nude            Detect Nudity, It works only with JPEG, *BETA*
   -d {md5,sha256,sha512,all}, --digest {md5,sha256,sha512,all}
                         Calculate perceptual image hashing
   -p {ahash,phash,dhash,whash,all}, --percentualhash {ahash,phash,dhash,whash,all}
                         Calculate hash digest
   -o OUTPUT, --output OUTPUT
                         Output directory path
   -s, --sqli            Keep SQLite file after the computation
   -t {jpeg,tiff}, --type {jpeg,tiff}
                         Select the image, this flag can be JPEG or TIFF, if
                         this argument it is not provided, imago will process
                         all the image types(i.e. JPEG, TIFF)
The only required argument is -i which is the base directory from which imago will start to search for image file. You should also provide at least one type of extraction (i.e. exif, data, gps, digest).

Example:
$ imago -i /home/solvent/cases/c23/DCIM/ -o /home/solvent/cases/c23/ -x -s -t jpeg -d all
Where:
  • -i path: is the base directory, where imago will search for file
  • -o path: the output directory where imago will save the CSV file, with the extracted metadata
  • -x : imago will extract EXIF metadata.
  • -s: the temporary SQLite database will not be deleted after the processing.
  • -t jpeg: imago will search only for jpeg images.
  • -d all: imago will calculate md5, sha256, sha512 for the jpeg images.
