Hello folks, I've written a script (BATCH) to automatically load the program
from a previous saved state.
This script only works on Windows, but I guess it could be adapted to other OS
I've written it based around multi-core extension given in the link below.
Another feature of this script is that it automatically saves the password to
a txt file. (Tee.exe is used for this intent).
- Use Andreas Meier's PDF multi-threating extension - download
- tee.exe -> it was hard for me to find this linux command for windows, but I've uploaded it for your benefit
How to use it:
Just place the tee.exe and the batch file in the same directory as
Run the pdfcrack as normal, according to your own parameters, then when you
close the program, you can just resume the brute force attack by running /
double clicking the batch file.
Just in case, here is the script for the batch file I've created:
:: NUMBER_OF_THREADS - This next line sets the maximum number of cores / threads to be used
:: display the header
echo Resuming the Brute Force Attack using %numOfThreads% threads
:: if 'savedstateperiodic.sav' is newer than 'savedstatecrash.sav' then copy it's contents to *..crash.sav
xcopy /d /q /y savedstateperiodic.sav savedstatecrash.sav > nul
:: start the brute force attack
@ echo on
pdfcrack.exe -l savedstatecrash.sav -t %numOfThreads% | tee log.doc
:: Save / Append Password
findstr /c:"found user-password:" log.doc >> passwords.txt && echo. >> passwords.txt && echo User-Password was saved to: passwords.txt
:: delete the log file
:: display message and exit
echo Press any key to exit . . .
pause > nul
