Stegdetect is an automated tool for detecting steganographic content in images.

URL: http://www.outguess.org/detection.php

This repo contains the 0.6 sources with compilation fixes for modern dev environments and Android (ARM).

To build on x86_64 you must prefix the commands with linux32, like so

    $ linux32 ./configure
    $ linux32 make

You can now run stegdetect from the local directory: ./stegdetect

This Android build is sort of fragile, there are many compile warnings.

You must set the environment variable NDK_BASE to the root location of your Android NDK.

    $ make clean
    $ make -f Makefile.android

Stegdetect does two types of F5 detection, simple and "slow". Simple merely looks for a comment in the header, which any savy coder has removed. This method is enabled with the "-tf" option.

The "slow" F5 detection is enabled with "-tF"

To run detection on a directory of JPEGs use:

    for img in `find /path/to/images/ -iname "*jpg"`; do
        ./stegdetect -tF $img;
    done

Android

    $ adb push stegdetect /data/local/tmp
    $ adb shell
        for img in `ls /sdcard/PixelKnot/*jpg`; do
            /data/local/tmp/stegdetect -tF $img
        done
