Imago is a forensic tool that will help to find Digital evidence from images. It is a command-line tool that is compatible with Windows, Linux, and macOS operating systems. In this article, we will take a closer look at Imago Forensic Tool, how it works, and its benefits in forensic investigations.
This tool will help you to store collected information about the image in a CSV file or in an SQLite database. This tool can help to extract more data like longitude, latitude, city, nation, and zip code.
Installing imago
Now let’s look at how can we install the imago tool on your computer. You can do this by the following command.
pip install imago
You can find the GitHub repo here
once you successfully installed the imago tool by the above command now let’s look at how can we use this tool to find digital evidence from an image
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)
Example
$ imago -i /home/solvent/cases/c23/DCIM/ -o /home/solvent/cases/c23/ -x -s -t jpeg -d all
