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]

now you can crack any image!,

example on how to use stegbrute

stegbrute -f image.jpg -w wordlist.txt -x results.txt

where -f is the file you want to crack, -w is the wordlist (a big list of passwords), -x is where you want to save your results, output :

https://github.com/R4yGM/StegBruteBruteforcing the file 'image.jpg' with the wordlist 'wordlist.txt' using 3 threads
(thread-0) Failed to crack the file, finished the passwords 178.02ms
(thread-2) Failed to crack the file, finished the passwords 284.84ms
password try: cool123 - Success
File extracted!
Password: cool123
Results written in: results.txt
Tried passwords : 62
Successfully cracked in 499.64ms

Enter fullscreen mode Exit fullscreen mode

it’s pretty fast, stegbrute tried 62 passords in half a second! as you can see it also shows the status of every thread

Comparision

I saw around also stegcracker wich is also a great program so i tried to compare it to stegbrute, and these are the results:

stegcracker :

# time stegcracker image.jpg wordlist.txt | grep -E "real|user|sys"real    0m1.754s
user    0m0.420s
sys     0m0.362s
Enter fullscreen mode Exit fullscreen mode

stegbrute :

# time stegbrute -f image.jpg -w wordlist.txt | grep -E "real|user|sys"real    0m0.553s
user    0m0.366s
sys     0m0.460s
Enter fullscreen mode Exit fullscreen mode

this says that stegbrute is more faster than stegcracker (i also tried to compare using other large wordlists)

Benchmark

I also made a benchmark of stegrute using different large wordlists i found on the internet

the table can be found here

these values ​​of course can vary on due to your machine power
