Stegbrute – Fast Steganography Bruteforce Tool Written In Rust Useful For CTF’s

stegbrute is a fast steganography brute force tool written in Rust using also threads to achieve a faster execution

Dependencies

Stegbrute cannot run without steghide!, to install steghide run :

apt-get install -y steghide

if you are not in a debian distribution you can download it from steghide website

Installation

stegbrute can be installed in different ways:

Cargo

throught cargo (Rust package manager)

if you don’t have cargo you can install it either from apt or by downloading Rust lang

cargo install stegbrute

this will work for every platform

Debian distributions

if you have ubuntu/kali or other debian distributions you can install the .deb file you find on the releases section, then unpack the file and run it

wget https://github.com/R4yGM/stegbrute/releases/download/0.1.1/stegbrute_0.1.1_amd64.deb &&
dpkg --install stegbrute_0.1.1_amd64.deb

Docker

if you don’t have docker installed you can follow their guide

first you have to pull the docker image (only 4.93 MB) from the docker registry, you can see it here, if you don’t want to pull the image you can also clone the repository and then build the image from the Dockerfile

docker pull r4yan/stegbrute:latest

you can also decide to pull different images by replacing ‘latest’ with a stegbrute version, ex.

docker pull r4yan/stegbrute:0.1.0

if you don’t want to pull the image you can download/copy stegbrute Dockerfile that can be found here and then build the image from the Dockerfile

then if you want to launch the container you have to first create a volume to share your files to the container

docker volume create --name stegbrute_data

then move or copy the files you want to use for stegbrute inside the volume folder wich usually is here /var/lib/docker/volumes/stegbrute_data/_data by just doing

cp wordlist.txt /var/lib/docker/volumes/stegbrute_data/_data && cp file.jpg /var/lib/docker/volumes/stegbrute_data/_data

and now run stegbrute

docker run -v stegbrute_data:/stegbrute_data -it --rm --name stegbrute r4yan/stegbrute:latest <options>

replace the <options> with the options/arguments you want to give to stegbrute, once you did everything you don’t have to pull/build the image again only if there are new updates or features

Always save your results inside the volume and not in the container because then the results will be deleted! you can save them by adding this option -x /$VOLUME_NAME/results.txt or --extract-file /$VOLUME_NAME/results.txt

if you added this and did everything correctly at the end of every attack you’d find the results inside the folder /var/lib/docker/volumes/stegbrute_data/_data

this will work for every platform

Executable

you can also download the already compiled programn and then execute it, example :

wget https://github.com/R4yGM/stegbrute/releases/download/0.1.1/stegbrute && chmod +x stegbrute
mv stegbrute /usr/local/bin/

Usage

stegbrute is very simple to use and it gives you many options, you can view the program help with the -h or –help option

StegBrute 0.1.1

Steganography bruteforce tool

USAGE:
    stegbrute [FLAGS] [OPTIONS] --file-name <file-name> --wordlist <wordlist>

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information
    -v, --verbose    shows every try the program does

OPTIONS:
    -x, --extract-file <extract-file>       the file name path where you want to write the results [default:
                                         stegbrute_results.txt]
    -f, --file-name <file-name>          the file name path you want to crack
    -t, --threads <threads>              number of threads to bruteforce the file [default: 3]
    -w, --wordlist <wordlist>            path of the wordlist

for example :

Options :

• -x or --extract-file with <file_name> will save the results of the extracted data into the file_name, if no file is specified stegbrute will save your results inside ./stegbrute_results.txt file

• -t or --threads with <number_of_threads> will launch a number of programs bruteforcing the file simultaneously, incrementing the number of threads doesn’t always mean this will run more faster it all depends on how many threads your machine can handle

• -f or --file_name with <file_name> the file name that stegbrute is going to attack, must be one of these supported formats : JPEG, BMP, WAV or AU

• -w or --wordlist with <wordlist> the file where stegbrute is going to take the passwords line by line and then start trying them to the file you want to crack, if you don’t have one you can install for example rockyou.txt
