stegdetect

Note: This repo is a code mirror of the original source which is now dead. Here is a working archive of the page.

Stegdetect and Stegbreak have been developed by Niels Provos.

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

This repo has been updated to compile cleanly on Ubuntu since the original project appears to be abandoned and no longer accepts pull requests.

Tested on Ubuntu 16.04 and 18.04 only(17.x likely works though)

Building on 64-bit Systemgs

    $ linux32 ./configure
    $ linux32 make

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

Build for Android

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

Usage

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
